Answer:
The atomic model is our understanding of how the atom is structured. At one point in history, people believed that any substance was simply made of that substance and would retain that property no matter how small a quantity it was reduced to. Later, some argued that all matter was made of tiny particles called atoms. While this is correct, later researchers found that even the atoms were made of smaller particles called electron, protons, and neutrons. More recently, scientists have discovered quarks, tiny particles that makeup protons and neutrons.

3. What do shaded shapes represent
Answer:
A completely shaded circle or square indicates that a person expresses the trait. A circle or square that is not shaded indicates that a person neither expresses the trait nor is a carrier of the trait. A black X represents death of the individual.
Solids have a definite:
a Shape
b Volume
c Arrangement of atoms, molecules
d All of the above
Answer:
d all of the above :)
Explanation:
hope this helped
Answer:
D) All of the above.
Explanation:
The Shape of a solid does not change (with exceptions), and the atoms typically remain static with little freedom of movement.
The volume of the solid also stays exactly the same if no external adjustments are made.
The arrangements of atoms & molecules are definitive and packed together, giving little movement, therefore allowing the solid to keep form.

In your own words, describe the way the nervous system is organized.
Answer:
lol here!
Explanation:
The human central nervous system contains the brain, spinal cord, and retina. The peripheral nervous system consists of sensory neurons, clusters of neurons called ganglia, and nerves connecting them to each other and to the central nervous system.
also
The nervous system consists of two parts, shown in Figure 1: The central nervous system (CNS) consists of the brain and spinal cord. The peripheral nervous system (PNS) consists of nerves outside the CNS.

How can I get my own karyotype?
If you guys don't know what karyotype is, it's a photo of person's full set of chromosomes. So basically my crush keeps making fun of me and said "You're so d*mb, you probably lost a chromosome" but I didn't lose any. So I want to sign up to get my own karyotype to prove I have a full set of chromosomes. Do you guys know which site I can sign up and pay to get my karyotype done? Thx
Answer: really any doctor
Explanation: karyotype tests are done typically during pregnancies, i’m sure a medical facility could do it.

Messenger RNA created through the process of transcription moves from the:
A: nucleus out to the ribosomes where translation takes place
B: ribosomes into the nucleus where
translation takes place
C: nucleus out to the lysosomes where translation takes place
D: ribosomes out to the nucleus where translation takes place
Answer: a
Explanation: transcription takes place in the nucleus. RNA leaves the nucleus to go to the ribosome where translation occurs.
Phage are viruses that must infect bacteria to reproduce. Viral genomes do not contain all the genes needed to produce all proteins necessary for DNA replication, RNA transcription, and protein translation; instead the viruses force bacterial proteins and enzymes to express phage genes instead of bacterial genes.
Phage are very adaptable, and their behavior depends on whether conditions are favorable or unfavorable for making more phage.
When bacteria are plentiful (favorable conditions), viral DNA within the bacteria remains separate from the bacterial chromosome, and the virus forces the bacteria to make more virus. When the amount of virus becomes too much for the cell to hold, the membrane ruptures, and viruses are released to infect surrounding bacteria. This is known as the lytic cycle.
When bacteria are scarce (unfavorable conditions), the viral DNA within the bacteria becomes integrated into the bacterial chromosome. The bacteria survive and are still able to reproduce; viral DNA is transmitted to daughter cells when the bacteria reproduces. This is known as the lysogenic cycle.
As you just read, phage depend on bacteria to reproduce. Phage can be maintained by infecting a culture of bacteria with a strain of phage, and then plating the bacteria on an agar plate to grow.
Suppose that you isolate two mutant strains of phage - one strain cannot enter the lytic cycle and the other strain cannot enter the lysogenic cycle. You also grow wild-type phage as a control. You see three different phenotypes:
A plate with no missing bacteria- the lawn of bacteria is intact
A plate with spots/circles (called plaques) where there are absolutely no bacteria in the circles
A plate with spots/circles (called plaques) where there are some bacteria in the center of the circles.
Based on what you know about what happens in each cycle, match the plating results with the identity of the strain.
Drag each plate into the correct category.
Answer:
A plate with no missing bacteria- the lawn of bacteria is intact----strain with lysogenic cycle.
A plate with spots/circles (called plaques) where there are absolutely no bacteria in the circles---- lytic cycle
A plate with spots/circles (called plaques) where there are some bacteria in the center of the circles----- wild type phage.
Explanation:
The strain which cannot enter the lytic cycle having no missing bacteria on the plate because the virus remains inside the bacterial cell while on the other hand, the other strain that cannot enter the lysogenic cycle having no bacteria on the circle due to infection of virus spreads throughout the cells and no bacterial cell remains uninfected. One plate having some bacteria and some space having no bacteria due to virus of wild type that shows both cycles.
How does aerobic respiration differ from anaerobic respiration ?
I need long answer, and correctly explained.
Answer:The difference between aerobic and anaerobic respiration.
Aerobic respiration Anaerobic respiration
1. Aerobic respiration refers to complete breakdown of metabolic fuels in presence of oxygen. 1. Anaerobic respiration is the process of partial breakdown of fuel (glucose) in absence of oxygen.
2. It includes glycolysis, citric acid cycle and oxidative phosphorylation. The first two processes take place in the cytoplasm while last one occurs in mitochondria. 2. Glycolysis is followed by ethanol fermentation (occurs in yeast) or lactic acid fermentation (in muscles and microbes like lactic acid bacteria).
3. The end products are carbon dioxide and water. 3. End products of ethanol fermentation are ethanol and carbon dioxide; that of lactic acid fermentation are lactic acid
4. Owing to complete oxidation of glucose, a large amount of energy is produced (36-38 ATP molecules) 4. Incomplete oxidation of glucose does not release all stored energy and only 2 ATP molecules are produced.
Anaerobic respiration is carried out by yeast and other anaerobic organisms like lactic acid bacteria, E. coli, Staphylococcus, Clostridium etc.
