The map shows areas of upwelling. Climate scientists predict that upwelling
may intensify along the western coast of the United States. What effect is
more intense upwelling likely to have on this area?

A. More starved marine species

B. Diminished ocean productivity

C. Fewer marine species

D. More nutrients for photosynthesis

Answer:

I think the answer may be D for you because for me the correct answer was “more thriving fish in the area” I’m so sorry if that isn’t the correct answer though

A wildfire burns through a grassland in the dry Texas Hill Country. The grass on the knolls burns and turns into ash, and the ash forms a layer on the ground. With the first rain, seedlings begin to sprout. Which of the following is most likely to occur in the coming years?

A
The Hill Country will see a decrease in species diversity because the main plants in the area have burned away.

B
The Hill Country will see no change in species diversity because the number of new species will equal the number of old species.

C
The Hill Country will see a decrease then an increase in species diversity because all of the old species will be replaced by new species.

D
The Hill Country will see an increase in species diversity because the soil has been enriched by the ash.

Every organism has a unique ecosystem in which it lives. This ecosystem is its natural habitat. This is where the basic needs of the organism to survive are met: food, water, shelter and a place to breed. All organisms need to adapt to their habitat to be able to survive. Animals and plants with adaptations that make them better suited for the environment will survive and reproduce better than those less suited for the environment. What adaptations are beneficial in the taiga or boreal ecosystem, marked B on the map? Select ALL that apply

Read through this series of events that lead to cellular respiration, or the production of energy in your body. Put these events in the correct order by numbering them from 1 to 5 in the blank boxes next to the events.

You eat a hamburger and breath oxygen
Oxygen and glucose combine to form carbon dioxide, water, and ATP.
Energy is used by cells in your body to function and grow; you exhale carbon dioxide.
Oxygen goes immediately from your lungs to blood vessels to cells.
Food molecules in the hamburger are broken down into glucose in the digestive system.

Let’s think about mutations in the context of selection and evolution. Normally, random mutations are very rare, but this process can be accelerated by using DNA damaging agents. Imagine you are working with yeast. Normally, high levels of salt kill yeast. However, you are conducting a random genetic screen to find salt-tolerant mutants. You use a DNA damaging agent (like EMS, or UV light) to damage the yeast DNA, then look for growth on plates with salt.

a. Does putting the yeast on salt cause the beneficial mutation? Why or why not?
b. If you screened your mutagenized yeast cell population on caffeine (another substance that normally kills them), could you find caffeine tolerant ones? (assume there is the potential for genetic resistance to caffeine).

Suppose that you have cancer cell line X was treated with drug Y to
increase the expression levels of protein Z which is a tumor

On a shade-grown coffee plantation, smaller coffee plants grow in the shade
of forest trees. The practice produces fewer coffee beans than growing
coffee in full sun, but it is more sustainable because it provides habitat for
forest birds. What is one disadvantage of shade-grown coffee farming?
O A. It provides farmers with only one kind of crop.
B. It generates lower profits from coffee bean sales.
О
C. It increases soil erosion.
O D. It reduces habitat for native species.

3) Besides pH, what other soil factors affect producers?

4) What is the main reason plants require water

If Bob and Mary were to have four offspring, what would be the
probability that all of the offspring would be blue?
Hints
a. 0.5 x 0.5 x 0.5 x 0.5 = 0.0625 or 6.25%
b. 50 x 50 x 50 x 50 = 6,250,000 or 62.5%
C. 0.5 +0.5 +0.5 +0.5 = 2.0 or 200%
d. It would be impossible for them to have four blue offspring in a row.

She is puzzled that the clone does not have an effect, even though she knows, based on available mutants, that loss of the function of this gene causes worms to die as larvae. You look at the sequence of the DNA she used to make the feeding clone and discover that it corresponds to an intron in the gene. What would you say to the student to explain why her experiment did not succeed
