Question 17 : Describe the features on this map. Where is it steepest? Explain how you can tell that it is the steepest. Which way is the river flowing and how do you know?
Answer:
It is steepest at point B and the river is flowing to the bottom right or southeast of the map.
Explanation:
We can tell that the map is steepest at point B because the lines that display altitude are closest together. Each line indicates 100 miles gained or lost to the overall altitude of the mountain. With the lines closest together, altitude is gained at the most rapid rate, and is therefore the steepest.
Additionally, we can conclude that the river is flowing southeast also because of altitude. The river runs from 1000 altitude to 500 altitude. Since rivers always run downhill, the river will run from the higher northwest point on this map to the much lower southeast point, and is therefore flowing southeast.
What would require more land to grow food crops? If all humans ate only vegetables
or ate only meat. Explain.
Answer:
If all humans ate only meat, will require more land to grow food crops
Explanation:
1) Currently, over 60% of the world food crops are eaten by animals. Given that food crops are generally consumed more than meat in a proportion of 8:1, if all humans ate only meat, the amount of land required to grow food crops will have to be increased by at least 400%
2) Presently, animal agriculture makes use of 70% of lands allocated to agriculture, such that increasing the livestock by an extra 400% will lead to mass deforestation in order to produce livestock feeds
3) It is more costlier to produce livestock than to produce crops, which will make the availability and allocation of land essential for the raising of livestock in order to reduce costs, thereby taking more land.

The role of the cell membrane is most like the job of which person?
Answer:
The officer that allows people in and out of the crime scene.
Explanation:
The cell membrane chooses what comes in and out of the cell, therefore the officer would be most similar to the job of the cell membrane.
Answer:
It has a job similar to a police officer who allows select people to enter and leave a crime scene.
Explanation:
The primary purpose of the cell membrane is to preserve the cell from its surroundings. The cell membrane manages the movement of materials in and out of cells and organelles. In this form, it is selectively perforable to ions and organic molecules. It is the same as of police officer or security guard that check the people and allow only a few to enter a specific place.

how is mitosis related to the cell cycle ?
Answer:
Mitosis is the the point in the cell cycle associated with division or distribution of replicated genetic material to two daughter cells. During mitosis the cell nucleus breaks down and two new, fully functional, nuclei are formed.
Explanation:
Answer:
In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

Answer:
Osmosis across the membrane
Explanation:
The diagram shows the movement of water molecules from outside the cell to the inside of the cell. The concentration of water molecules is higher outside of the cell than inside the cell, meaning the water molecules are moving from a high concentration to a low concentration across the semi-permeable membrane, a process called osmosis.
Exocytosis is the movement of molecules from the inside of the cell to the outside via a vesicle. The vesicle fuses with the plasma membrane and the contained substances are released outside the cell.
Active transport is the movement of molecules against their concentration gradient and requires energy.
Facilitated diffusion is used by molecules that cannot freely cross the plasma membrane (e.g. large polar molecules and ions)
Answer:
Osmosis across the membrane

Answer:
The zebra mussel invasion has had profound effects on the Hudson River ecosystem. The food web changes that the mussel has caused compare in magnitude to disturbances in other aquatic ecosystems caused by toxins, nutrient pollution, or acid rain.In spite of their small size (often no bigger than a penny) zebra mussels cause far-reaching damage to water structures and native ecosystems. ... They also negatively impact aquatic ecosystems by harming native organisms. In huge numbers, they out-compete other filter feeders, starving them.

How do high temperatures
affect enzyme activity?
Answer:
Increased temperatures can cause enzymes to work more quickly, if the temperature gets too high the enzyme stops working.
Explanation:
If the temperature around an enzyme gets too high, the enzyme loses its shape, which is known as denaturation, and ceases to work.

Is endocytosis a form of active
transport?
A. Yes, because molecules move down the
concentration gradient without using energy.
B. No, it is a form of diffusion.
C. Yes, because it requires energy to move a
molecule against a concentration gradient.
Answer:
A. Yes, because molecules move down the
concentration gradient without using energy.
Explanation:
Active transport is the energy-requiring process of pumping molecules and ions across membranes against a concentration gradient. Both endocytosis and exocytosis are active transport processes.

Kaya had an organ transplant. She went to the doctor a week later, and the doctor did a blood test. Her lymphocyte count
had increased. She went to the doctor a month later for the same test, and her lymphocyte count was higher. What is the
best explanation as to why her lymphocyte levels were increasing?
O Kaya was given antibiotics to prevent infections.
Kaya's antigens were attacking the tissue.
Kaya was not tissue typed prior to her surgery, and her body is mounting an immune response.
O Kaya took her immunosuppressant drugs weekly, which increased her lymphocyte count.
Answer:
The best explanation for the increased lymphocyte levels in Kaya is that she was not tissue typed prior to her surgery, and her body is mounting an immune response.
Explanation:
When performing an organ transplant, it must be verified whether the organ to be transplanted is compatible -by tissue typing- with the recipient, since it is recognized as a foreign body by the body and can be rejected.
One of the immunological responses to organ rejection is called cell rejection, involving T-helper and cytotoxic lymphocytes.
It is very likely that in Kaya's case the tests have not been performed correctly, and she is experiencing rejection of the organ she received. The progressive increase in lymphocytes may be an indication of this.
The other options are not possible because:
Administering antibiotics should not raise lymphocyte levels. There is no evidence of antigen attack. Immunosuppressant drugs do not increase lymphocyte count.If all of the ribosomes in a cell disappeared, which of the following will happen?

Answer:
Argon
Explanation:
Argon is a chemical element which is a gas at room temperature, has 8 valence electrons and 22 neutrons. This element belongs to the noble gas elements group.
What is Argon?Noble gas is any of the rare gases that include helium, neon, argon, krypton, xenon, and sometimes radon also and that exhibit great stability and extremely low reaction rates than other elements in the periodic table.
Argon is a chemical element with the symbol Ar and it has an atomic number of 18. It is in the group 18 of the periodic table and it is a noble gas. Argon is the third-most abundant gas in the Earth's atmosphere, at 0.9340 ppmv. It is more than twice as abundant as that of water vapor, 23 times as abundant as carbon dioxide, and more than 500 times as abundant as neon gas. Argon is the most abundant noble gas in the Earth's crust, which comprises about 0.00015% of the crust.
