The chemical energy that animal cells use most directly to produce heat and to carry out life processes comes from _______.

1 answer:

4 0

The chemical energy that animal cells use most directly to produce heat and to carry out life processes come from the oxidation of glucose using oxygen. Cells generate energy from the controlled breakdown of food molecules. During cellular respiration the cells use food molecules, mostly glucose to generate energy in the form of ATP, that used to drive all cellular activities.

How is solar energy absorbed and admitted by earths surface?

mylen [45]

Answer:

About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Of the 340 watts per square meter of solar energy that falls on the Earth, 29% is reflected back into space, primarily by clouds, but also by other bright surfaces and the atmosphere itself. About 23% of incoming energy is absorbed in the atmosphere by atmospheric gases, dust, and other particles. The remaining 48% is absorbed at the surface

Lena [83]

Answer:

No, observed and expected frequencies are different.

Observed frequencies: p2 = 0.56 , 2pq = 0.375, q2 = 0.062

Expected frequencies: p2 = 0.774 , 2pq = 0.211, q2 = 0.014

Explanation:

Given frequency of recessive genotype (q2)= 14/ 1006 = 0.0139

Frequency of recessive allele s (q) = square root of 0.0139 = 0.12

Frequency of dominant allele S (p) = 1-q = 1-0.12 = 0.88

Expected frequency of homozygous recessive genotype = 0.12 x 0.12 = 0.014

Expected frequency of homozygous dominant genotype = 0.88 x 0.88 = 0.774

Expected frequency of heterozygous dominant genotype = 2pq = 2 x 0.88 x 0.12 = 0.211

Observed frequencies in population 2

Observed frequency of homozygous dominant genotype = 308 / 549 =0.56

Observed frequency of heterozygous dominant genotype = 206 / 549 =0.375

Observed frequency of homozygous recessive genotype = 34 / 549 =0.062

Observed frequencies do not match with expected frequencies.

What is one possible message that one cell might send to another cell

Andreas93 [3]

<span>that really just depends on what type of cells we are talking about here. :) Bacterial cells can send a huge array of signals, like in pathogenic bacteria at the time of colonization, they send out signals to neighboring cells in the form of chemical substances to produce virulence factors like toxins. In short, gene regulation changes are brought about. This is just one example and is one of the effects of a process called Quorum Sensing. </span>
