Answer: I know the answer is environmental science because I just took the test.
Explanation:
Hannah must be working in the environmental science discipline.
Environmental science is a branch of science that deals with the study of the environment.
In environments, there are both living and nonliving factors. The living factors are called biotic factors and the nonliving factors are called abiotic factors.
The living factors include all the living organisms ranging from plants to animals while the nonliving factors include soil, temperature, salinity, sunlight, wind, pressure, etc.
Both the living and nonliving factors interact with each other in a rather complex way.

Which of the following is TRUE about the polarity of water?
(1 Point)
only H atoms have electrons
electrons are more strongly attracted to the H atom
electrons are more strongly attracted to
the O atom
electrons are shared equally between all atoms within the molecule
Answer:
electrons are more strongly attracted to the O atom
Explanation:
It is true that in the in the polarity of water, electrons are more strongly attracted to the oxygen atom compared to the hydrogen atom.
In a water molecule, there are two atoms, hydrogen and oxygen. These atoms are bonded together by covalent bonding. Oxygen is more electronegative compared to Hydrogen. It pulls the shared electron more itself compared to hydrogen. This leaves a net negative charge on the oxygen and net positive charge on the hydrogen. The charge separation makes water polar.Which process best describes the effect of weathering on Earth’s surface?
A. volcanoes erupting
B. new mountains forming
C. evaporation of surface water
D. rocky cliffs breaking down
Help please!! What force pulls the "dust" together into a cloud
Answer: gravity
Explanation:
Answer:
GRAVITY pulls dust and gas in interstellar clouds together, but because the electrostatic force over short distances is so much stronger than gravity, even a small electrostatic repulsion between dust grains can influence (and possibly prevent) a cloud's collapse.

• What is a genetically modified organism/food? What was the first GM food commercially available?
• What benefits do GM foods offer to both the consumer and agricultural industry?
• What risks do GM foods present to consumers? (Ex: health, economic, etc.)
• What are the laws/regulations affecting GM foods in the United States?
• In your opinion, do consumers have a right to know if the foods they are buying contain GMOs?
• How are you personally affected by GM foods? If the foods you enjoy eating were genetically
modified, would you consider changing your diet?
Answer:
Genetically modified food is food whose genes have been modified in some way to bring more desirable traits
Explanation:
Some benefits GMOs
-Diesease and drought resistant crops
-Faster growing organism/faster food production
-Lower prices of food since more is being produced
-Decreased use of pesticides
It doesn't change anything if the food consuumers use are GMO or not. Most foods don't have to list every specific ingredient the purchaser is consuming, so why would they need to specify if GMOs are used when they are completely harmless?
Everyone is personally affected by GM foods/organisms. The food prices would be a lot higher if it wasn't for GMOs.
If the foods I enjoy eating were GMOs I wouldn't change my diet since there are no proven downsides to eating GM foods.
1. The cells in our bodies are surrounded by these types of solutions.
3. When an animal cell is places in this solution, it will burst (get layer)
4. When an animal cell is placed in this solution, it will shrivel or shrink (get smaller).
A) isotonic solution
B) hypertonic solution
C) hypotonic solution
Answer:
1. The cells in our bodies are surrounded by these types of solutions. → Isotonic solution.
3. When an animal cell is places in this solution, it will burst (get layer) → Hypotonic solution.
4. When an animal cell is placed in this solution, it will shrivel or shrink (get smaller) → Hypertonic solution.
Explanation:
The cells in the body are in a balance of substances —concentration of solutes— between their cytoplasm and the extracellular space. This balance is dynamic in living beings, due to the constant exchange of ions and substances between the intracellular and extracellular space. For this reason, the extracellular medium is isotonic with the cytoplasm.
A cell can lose or gain water depending on the amount of solutes that a medium has in which it is found, with respect to the cytoplasm. This difference in solutes concentrations produces an osmotic gradient that drags water from the least concentrated solution to the most concentrated, through the process of osmosis, which seeks to achieve an equilibrium of concentrations.
When a animal cell is exposed to a hypertonic solution —with a higher concentration of solutes— it loses water and tends to dehydrate and become smaller.An animal cell in a hypotonic solution receives water, so it can expand and even burst.In practice, the concentrations of intracellular and extracellular solutes depend not only on the osmotic gradient, but also on the concentration gradient of substances.

The two insulated beakers shown contain equal amounts of identical liquids. The temperature of Beaker A is 80°C. The temperature of Beaker B is 50°C. A copper rod connects the beakers. The system is then left alone for several hours. What would you expect to find when the system is examined after this time?
Answer:
After several hours, both beakers are expected to have the same temperature of 65°C
Explanation:
Given that:
The temperature in beaker A = 80°C
The temperature in beaker B = 50°C
The copper rod used to connect allows transference to heat and temperature from beaker A to the beaker B because it is a good conductor of heat and electricity. After several hours, movement of heat and the temperature have occurred and they have both reached equilibrium.
Therefore, after several hours, both beakers are expected to have the same temperature of 65°C
i.e.
= ((80 + 50)/2) °C
= (130/2)°C
= 65 °C

Edwards v. South Carolina is significant because it provides protection to protestors.
South Carolina, 372 U.S. 229 (1963), was a landmark decision of the US Supreme Court which states that the First and Fourteenth Amendments to the United states Constitution forbade the state government officials to force a crowd to disperse when they are marching legally in front of a state house for their rights and against the irregularities.
The Supreme Court ruled that South Carolina had violated the First Amendment rights of peaceable assembly, speech, and petition when the police forcefully dispersed a peaceful protest against segregation so we can conclude that Edwards v. South Carolina is significant because it protect protestors.

D
Explanation:

Diatoms are photosynthesizing algae having a siliceous skeleton (frustule) and are found in almost every aquatic environment including fresh and marine waters, soils, in fact almost anywhere moist.
Cell Organelles present in Diatoms work together to carry out all the life functions.
What is Diatom?Diatoms as mentioned above are unicellular organisms which occur either as solitary cells or in colonies and can take different shapes.
Individual cells range in size from 2 to 200 micrometers.
A unique feature of diatom anatomy is that they are surrounded by a cell wall made of silica (hydrated silicon dioxide), called a frustule. These frustules have structural coloration due to their photonic nanostructure, prompting them to be described as "jewels of the sea" and "living opals".
Movement in diatoms primarily occurs passively as a result of both ocean currents and wind-induced water turbulence.
Similar to plants, diatoms convert light energy to chemical energy by photosynthesis, but their chloroplasts were acquired in different way.
Diatoms are classified as eukaryotes due to presence of cell organelles i.e. with a nuclear envelope-bound cell nucleus, that separates them from the prokaryotes archaea and bacteria.
Diatoms are a type of plankton called phytoplankton, the most common of the plankton types. Diatoms also grow attached to benthic substrates, floating debris, and on macrophytes.
They comprise an integral component of the periphyton community.
Another classification divides plankton into eight types based on size.
Diatoms are used to monitor past and present environmental conditions, and are commonly used in studies of water quality.
What are Cell Organelles?Cell organelles are specialized structure which perform specific functions in cells.
Among the more important cell organelles are the nuclei, mitochondria, and ribosomes, which assemble proteins.
Based on the presence and absence of organelles, cells are divided into Prokaryotic and Eukaryotic cells.

Which of the following can you correctly infer from the graph about how the pH affects the enzyme's role in the target chemical reaction?
A line graph showing rate of enzyme action versus pH. The graph indicates pH on the x-axis with a numbered line increasing to the left. The graph also indicates the rate of enzyme action as it increases on the Y-axis. A line starts at approximately 4.5 on the x-axis and climbs to a steep peak at approximately 9 on the x-axis. The line then declines at the same rate and levels out to its starting position at approximately 13 on the x-axis.
There is a specific pH range in which the enzyme effectively lowers the reaction's activation energy.
Increasing the pH makes it easier for the enzyme to lower the activation energy of the target reaction.
As the pH increases, the activity of the enzyme to lower reaction activation energy is decreased.
The enzyme will not assist the chemical reaction at a pH that is below 6 or above 12.
Answer:
I'm going to say since I cannot see the graph i'm guessing that it shows an enzyme at its peak and lowering so i'm going to say the first one 1) There is a specific pH range in which the enzyme effectively lowers the reaction's activation energy

If a fault is currently locked, it is not moving. True O False
Answer:
if it is not slipping, then no
Explanation:
A locked fault is a fault that is not slipping because frictional resistance on the fault is greater than the shear stress across the fault (it is stuck). Such faults may store strain for extended periods that is eventually released in an earthquake when frictional resistance is overcome. Have a great day! :)
Which activity uses ATP to raise body temperature?
shivering
storing fats
panting
hibernating
Answer:
shivering it creates energy, 60% of which is wasted on heat
Shivering uses ATP to raise body temperature. So the correct option is A.
What is shivering?Without your conscious involvement, your body controls how it reacts to stress, illness, heat, cold, and other situations. When you are too hot, for instance, you sweat to cool the body, but you don't have to think about it. And you shiver naturally when you're chilly.
Your muscles quickly contract and release, which results in a shudder. Your body naturally tries to warm up as it becomes cooler, which is why you are experiencing this uncontrollable muscular activity.
The only reason you shiver, though, is in response to the cold. You may tremble and shiver due to a variety of factors, including illness. You could start to shiver as the temperature falls below what your body considers comfortable. Your body's surface heat production might increase by around 500% when you can see yourself shivering. However, shivering will only temporarily warm you up.
Your muscles will eventually run out of glucose (sugar) to use as fuel and become too exhausted to contract and relax after a few hours. The temperature during which shivering begins varies depending on the individual. Children, for instance, may shiver more readily in reaction to higher temperatures than an adult with greater body fat would.
Therefore the correct option is A.
