Which one of the following accurately describes the reactions within photosynthesis? A. The light-independent reactions use ATP and NADPH.
(B.) The light-independent reactions are responsible for making ATP and NADPH. C. The light-independent reactions use the sunlight to drive its processes.
D. The light-dependent reactions are responsible for making sugars.

I put B but it was wrong.

Answers

Answer 1
Answer: It's probably C. Because it makes the most sense and photosynthesis doesn't make ATP and if you don't think C. Is the answer then put D.
Answer 2
Answer:

Answer:

The light-independent reactions use the sunlight to drive its processes.

Explanation:

This the true statement, because in photosynthesis processes, sunlight is needed to processes happen.

Remember that photosynthesis is a chemical reaction to produce food for the plants. This process take place in the leaves. Also, to this process happen is needed sunlight, water and carbon dioxide.

Hypothesis A: If heart rate is related to caffeine intake, then coffee drinkers will have higher heart rates. Hypothesis B: If a higher heart rate is related to caffeine intake, then the heart rate of most people will be higher 30 minutes after they drink a cup of coffee.

Which hypothesis is more useful and why?


A. The two hypotheses are equally useful.
B. Hypothesis A is more useful because it’s true.
C. Neither hypothesis is useful because they aren’t testable.
D. Hypothesis B is more useful because it suggests a way to test the relationship between heart rate and caffeine intake.

Answers

Answer: D. Hypothesis B is more useful because it suggests a way to test the relationship between heart rate and caffeine intake.

Hypothesis A and B both are suggesting that caffeine intake is related to higher heart rate. But hypothesis B is proving it more certainly by suggesting the affects of caffeine intake on heart rate. As, heart rate of most people will be higher 30 minutes after they drink a cup of coffee is testifying the fact, that higher heart rate is related with caffeine intake.

Therefore, hypothesis B is more useful because it suggests a way to test the relationship between heart rate and caffeine intake.
Hypotheses B is more useful because it suggests a way to test the relationship between heart rate and caffeine intake.

Larry moved from Chicago to Atlanta. For the first two years he lived there he had no allergies in the spring. Then, in the third year, he had very bad allergic reactions to spring pollens. What is the most likely explanation for this delayed effect?

Answers

This might have been the cause of not being exposed to this specific pollen during his years in Chicago. Allergic reactions can develop when the stimuli presented even when its not contagious causes the immune system to trigger and act in a defensive stance. This delayed effect may have been the cause of the sudden expression of the immune system. 

Answer:

The answer is c) his body had built up enough antibodies to cause the allergy symptoms. took the test on usa test prep.

What is punnet square?

A cross or breeding experiment's genotypes can be predicted using the Punnett square, a diagram with squares. This square bears Reginald C. Punnett's name, who created this invention in 1905.

Two heterozygous plant crosses will result:

  T         T                        Y         y

T   TT     TT                   y   Yy     yy

t    Tt       Tt                   y   Yy      yy

The ratio of TT =   1/2     The ratio of Yy =  1/2

The total ratio of TTYy is 1/2 x 1/2 = 1/4 = 25%.

Therefore, 25% of the progeny should carry the TTYy allele combination, according to expectations. The offspring produced is heterozygous.
