Answer:
Substances that do not form ions when they dissolve in water are called non-electrolytes. And example of a non-electrolyte is sugar. Sugar will readily dissolve in water but doesn't form cations and anions in solution. That is, there are no charge carriers formed.
It is very difficult to add or remove electrons from an atom that has eight electrons in its outer shell.
True

Answers
Explanation:
Electrons are typically removed from the valence shells, which are the highest s and p orbitals. Also, Hund's rule still applies here, but backwards. Electrons will be removed from their orbitals until all of them are unpaired, and then the unpaired ones will be removed.
May be true because velence shell is the outermost shell which can be removed.

PLEASE HELP ME IF YOU DONE THIS BEFORE Part 1: Introduction
Title
Title your lab report with a few words that
summarize the lab investigation
Purpose
The lab report should begin with one or two
sentences that state the purpose of the
investigation what you want to see, practice, loam
about, or test. The purpose statement answers the
question "What am I trying to find out by doing this
experiment?"
The three most common types of labs are:
inquiry labs, in which you measure how
changing one variable affects another variable
discovery labs, in which you observe a scientific
phenomenon, perhaps for the first time.
forensic labs, in which you gather and analyze
data as evidence to build an argument in
response to a question, as in a court case,
All three types of labs give you an opportunity to
learn important scientific skills and concepts.
Question
At its core, science is about inquiry, or the act of
asking questions and seeking answers. Most labs
begin as the result of a question, which is why the
introduction of your lab report should include a
question. For example, suppose you notice that you
seem to play basketball better at the court in one
park than in another. After conducting research, you
realize that one of the surfaces of the court at the
park is different from that of your driveway. As a
result, you might formulate the scientific question
"What effect does the court surface have on the
height that the basketball bounces?" To answer this
question scientifically, you could perform several
experiments and gather data,
Hypothesis (or Prediction)
A hypothesis is an initial answer to a question, a
possible explanation or expectation based on prior
knowledge or research. Before starting most lábs,
you will formulate a hypothesis. It should be listed in
the introduction of your tab report
A good scientific hypothesis states conditions,
expected results, and possible reasons for those
results, For example, you could respond to the
basketball question with a hypothesis like "If the
court surface is smooth concreto, as the park's
court is, then the basketball will bounce higher,
because smooth surfaces have better contact with
the ball." Like this hypothesis, hypotheses are often
structured using the format "il then, because
which is described below.
The "it' portion of the hypothesis describes
something that you will change in the experiment
• The "then" portion of the hypothesis describes
what you think will happen as a result of that
change
• The "because" portion of the hypothesis
describes the ason why you think that change
will occur
In other laboratory activities you will be asked to
make a prediction. You will conduct background
research, then predict the outcome of a known
scientific process
Special Note about inquiry Labs
For inquiry labs, questions are generally
written in the form of "What is the effect of X on
Y?" Hypotheses will generally be in the form of
X [describe how you will change X during the
experiment), then Y will predict how y will
change in response), because give your
reason." In many inquiry labs the variables
lend themselves to a scatterplot (X-Y plot)

For anyone else who needs help just write an essay on what ionic bonds are. Then write what covalent bonds are. Then write the difference between them. It’s better than getting in trouble for using someone else’s work.
The student guide made it very confusing as if you were doing a project but it’s not, it’s just an essay.
Answer:
Was gonna use some links but {insert anger} brainly doesn't allow it.
Explanation:
There are primarily two forms of bonding that an atom can participate in: Covalent and Ionic. Covalent bonding involves the sharing of electrons between two or more atoms. Ionic bonds form when two or more ions come together and are held together by charge differences.

How Enzymes Function Enzymes are biological catalysts. They can increase the rate of chemical reactions as much as a millionfold by lowering the energy barrier of a reaction.
Part A - Enzymes and activation energy The graph presents three activation energy profiles for a chemical reaction (the hydrolysis of sucrose): an uncatalyzed reaction, and the same reaction catalyzed by two different enzymes. Rank these by reaction rate, as measured by the rate of product formation (from the most product formed to the least product formed). To rank items as equivalent, overlap them.
Part B - Factors that affect enzymes Complete this vocabulary exercise relating to enzymes. Match the words in the left-hand column to the appropriate blank in the sentences in the right-hand column. HelpReset cofactor specific denatured substrate active site catalyst complex
1. An enzyme is when it loses its native conformation and its biological activity.
2. An enzyme is considered a because it speeds up chemical reactions without being used up.
3. An enzyme is considered because of its ability to recognize the shape of a particular molecule.
4. A , such as a vitamin, binds to an enzyme and plays a role in catalysis.
5. When properly aligned, the enzyme and substrate form an enzyme-substrate (ES) .
6. A substrate binds to an enzyme at the , where the reaction occurs.
7. In a catalyzed reaction a reactant is often called a _________.
Answers
Answer:1. An enzyme is denatured when it looses its native conformation and its biological activity. Enzyme is a protein and at high temperatures, the shape of the proteins is altered, preventing it from its function. In addition change in pH above optimal may also cause denaturation of enzymes inactive.
2. An enzyme is considered a catalyst because it speeds up chemical reaction without being used up. A catalyst is a substance that speeds up chemical reactions by reducing the activation energy of the reactants, they are not consumed during the reactions. Enzyme are biochemical catalysts that speeds up chemical enzymatic reactions without being consumed just like normal catalysts.
3. An enzyme is considered specific because of its ability to recognize the shape of a particular molecule. One property of enzyme is that they are substrate specific and will act on specific substrate, others will act on a specific type of chemical bond or functional group, while others will catalyze only one reaction (absolute specificity)
4. A cofactor such as a vitamin, binds to an enzyme and plays a role in catalysis. Cofactors are mostly metal ions (such as Zn ions or iron ions) or coenzymes are inorganic and organic chemical that aid the activity of enzymes. Coenzymes are non protein molecules mostly vitamins or vitamins derivatives that enhance enzyme activity.
5. When properly aligned, the enzyme and substrate form an enzyme-substrate (ES) complex. Es complex is the intermediate formed when a substrate molecule interacts with the active sites of an enzyme. After the formation of the complex then the substrate undergoes a chemical reaction and is converted to product.
6. A substrate binds to an enzyme at the active-site, where the reactions occurs. Active sites is a region on the enzyme where substrate molecules bind and undergoes a chemical reaction where it is converted to product. These sites contain the binding site and the catalytic site.
7. In catalyzed reaction, a reactant is often called a substrate. Substrate molecule is the substance that is acted upon by an enzyme and is converted to a product. The substrate forms an interaction with the binding site of the active site then the catalytic site of the active site converts the substrate to a product during catalysis.
1. Denatured
2. Catalyst
3. Specific
4. Cofactor
5. Complex
6. Active Site
7. Substrate
The induced fit model states an substrate binds to an active site and both change shape slightly, creating an ideal fit for catalysis. When an enzyme binds its substrate it forms an enzyme-substrate complex. ... The enzyme will always return to its original state at the completion of the reaction.
"The active site of the enzyme has a complementary rigid structure" belongs to the key and lock system

It is constant over equal periods of time, in accordance with Kepler's second law of motion. The right response is a.
It is constant if the planet moves at a constant speed. Option C
Describe Kepler's law.?The orbits of planets around the Sun are described by Johannes Kepler's laws of planetary motion, which were published between 1609 and 1619.
Kepler's second rule of planetary motion gives an explanation for the speed of a planet in an elliptical orbit around the Sun.
It asserts that similar areas are moved in equal lengths of time along a line drawn between the Sun and the planet.
As a consequence, the planet moves faster as it gets closer to the Sun and slower as it moves further away.
The transition from geocentrism to heliocentrism was ushered in by Kepler's laws of planetary motion.
Together with Earth, they provide the first quantifiable connection between the planets. Additionally, they depict a period when the key issues of the day were evolving.

Over 99.9% of the solar system is composed of hydrogen and helium. How does this help to explain the size differences between the terrestrial planets and the gas giants?
Answers
Explanation:
Gas giants/Jovian planets are also called the outer planets, they are made of gases, they are large and less dense, more moons. Terrestrial/Rocky planets are also called the inner planets. They are made of rocky surface, denser than Jovians, and small, little or no moons.
The information about the composition of solar system has great significance in providing data about size between the terrestrial planets and the gas giants planets.
The size differences occur between the terrestrial planets and the gas giants due to the presence of different concentration of gases in their compositions. Gas giants planets are also called the outer planets which are made up of gases.
They are large in size but having less density and more moons while on the other hand, terrestrial planets are made of rocky surface. They are also called the inner planets. They are more denser than gas giant planets, small in size and less or no moons so we can conclude that there is a great size differences between the terrestrial planets and the gas giants.

Stem cells are used to treat some human diseases.
Stem cells can be collected from early embryos. These stem cells have not begun to
differentiate, so they could be used to produce any kind of cell, tissue or organ. The
use of embryonic stem cells to treat human diseases is new and for some diseases,
trials on patients are happening now.
Stem cells can also be collected from adult bone marrow. The operation is simple
but may be painful. Stem cells in bone marrow mainly differentiate to form blood
cells. These stem cells have been used successfully for many years to treat some
kinds of blood disease. Recently there have been trials of other types of stem cell
from bone marrow. These stem cells are used to treat diseases such as heart

its attention during the early days of the civil rights movement on doing which of the following?
Answers
Answer:
Although the Declaration of Independence stated that "All men are created equal," due to the institution of slavery, this statement was not to be grounded in law in the United States until after the Civil War (and, arguably, not completely fulfilled for many years thereafter). In 1865, the Thirteenth Amendment was ratified and finally put an end to slavery. Moreover, the Fourteenth Amendment (1868) strengthened the legal rights of newly freed slaves by stating, among other things, that no state shall deprive anyone of either "due process of law" or of the "equal protection of the law." Finally, the Fifteenth Amendment (1870) further strengthened the legal rights of newly freed slaves by prohibiting states from denying anyone the right to vote due to race.
Despite these Amendments, African Americans were often treated differently than whites in many parts of the country, especially in the South. In fact, many state legislatures enacted laws that led to the legally mandated segregation of the races. In other words, the laws of many states decreed that blacks and whites could not use the same public facilities, ride the same buses, attend the same schools, etc. These laws came to be known as Jim Crow laws. Although many people felt that these laws were unjust, it was not until the 1890s that they were directly challenged in court. In 1892, an African-American man named Homer Plessy refused to give up his seat to a white man on a train in New Orleans, as he was required to do by Louisiana state law. For this action he was arrested. Plessy, contending that the Louisiana law separating blacks from whites on trains violated the "equal protection clause" of the Fourteenth Amendment to the U.S. Constitution, decided to fight his arrest in court. By 1896, his case had made it all the way to the United States Supreme Court. By a vote of 8-1, the Supreme Court ruled against Plessy. In the case of Plessy v. Ferguson, Justice Henry Billings Brown, writing the majority opinion, stated that:

Which of the following allows water to move much faster across cell membranes? A) the sodium-potassium pump B) ATP C) peripheral proteins D) aquaporins
Answers
Answer:
D
Explanation:
I believe the answer would be aquaporins
Aquaporins efficiently speed up the total rate of water diffusion across the cell membrane due to the slow diffusion of water through the lipid bilayer, hence option D is correct.
What are aquaporins?Aquaporins (AQP) are essential membrane proteins that act as conduits for the passage of water and, occasionally, tiny solutes.
The Na+ K+ pump is an electrogenic transmembrane ATPase that was initially identified in 1957. It is located on the cytosolic side of the cell's outer plasma membrane. For every ATP, the Na+ K+ ATPase pumps 3 Na+ out of the cell and 2K+ into the cell.
Therefore, animals, plants, and microorganisms all have them preserved. Every aquaporin molecule has a pore in the middle, according to structural investigations of the molecules.
