How are photosynthesis and cellular respiration alike?

1 answer:

3 0

The two main processes by which plant cells absorb, release, and use energy are photosynthesis and respiration. The process of photosynthesis is present in the chloroplasts of a pant cell. Photosynthesis uses the sun’s rays in the form of electromagnetic energy to convert it into chemical energy to be used for the plants. It needs proteins that are present in the plants to perform a series of necessary conversions. Moreover, the energy from the sun is the main catalyst to convert the carbohydrates in the plant into simpler sugars. And then a series of complex reaction takes place that their end product is oxygen. The oxygen produced is the cellular respiration.

As a result of global warming, what evolutionary changes could we infer might eventually be seen in polar bears?

mina [271]

Answer:

Loose of body hair, reduction of body fat percentage and changes in life habits.

Explanation:

One of the most notorious changes would be the loss of body hair, due to the temperature increase. The amount of hair that polar bears now posses, helps them with keeping their body warm in very cold temperatures, as well as the body fat, which would also be reduced because of the excess of heat. Finally, their life habits could also change, as for example, part of the body fat helps them with hibernation, so these periods could be reduced or even lost.

Suppose the human trait for freckles is controlled by a simple dominant and recessive relationship at one locus. Freckles, F, is

Dennis_Churaev [7]

Answer:

0.549 is the frequency of the F allele.

0.495 is the frequency of the Ff genotype.

Explanation:

FF or Ff genotypes determine freckles, ff determines lack of freckels.

In this class of 123 students, 98 have freckles (and 123-98= 25 do not).

If the class is in Hardy-Weinberg equilibrium for this trait, then the genotypic frequency of the ff genotype is:

q²= 25/123

q²=0.203

q= $\sqrt{0.2$

q= 0.451

q is the frequency of the recessive f allele.

Given p the frequency of the dominant F allele, we know that:

p+q=1, therefore p=1-q

p=0.549 is the frequency of the F allele.

The frequency of the Ff genotype is 2pq. Therefore:

2pq=2×0.549×0.451

2pq=0.495 is the frequency of the Ff genotype.
