Explanation:
<u>Answer</u>: 0.83 (=0.88-0.05)
Growth rate is the speed/rate at which the number of individuals within a population increases.
As the current growth rate of the fog beetles is 83%, the population will increase with 1660 individuals per reproductive cycle (N=N0*r --> N=2000*0,83 --> N=1660).
Explanation:
The problem says that the hairless phenotype never breeds true. That means that it's not the result of a homozygous genotype (H₁H₁ or H₂H₂), so it is caused by the heterozygous genotype (H₁H₂).
The <u>expected </u>offspring from the cross between two Mexican hairless would be:
<h3>P
H₁H₂ x
H₁H₂</h3><h3>F1 1/4
H₁H₁, 2/4
H₁H₂ and 1/4
H₂H₂.</h3>
And the <u>expected</u> phenotypic ratio 3:1. However, the observed offspring shows a 2:1 ratio. What's happening?
If the observed phenotypic ratio in the offspring of a monohybrid cross (a single gene with two alleles) is 2:1, we can suspect that one of the genotypes is lethal in homozygosis and therefore does not appear in the progeny (the puppies are born dead).
If we proposed that the H₂ allele is lethal in homozygosis, then:
- The H₁H₁ genotype would cause normal puppies --> 1
- The H₁H₂ genotype would cause hairless puppies --> 2
- The H₂H₂ is lethal and causes the death of puppies --> 0
The phenotypic ratios change to 2:1, as observed in the experiment.
Answer: The correct answer is- Solar energy, carbon dioxide, and water.
Light dependent reactions comprise the first phase of photosynthesis (formation of food by green plants and algae in presence of sunlight) process.
This phase occurs in the thylakoid membrane of chloroplast.
During this phase, a green pigment chlorophyll absorbs energy from sunlight (in the presence of carbon dioxide and water) and convert it into chemical energy in the form of ATP and NADPH.
This energy is further utilized in the formation of food (glucose) in the next phase, which is a light independent phase of photosynthesis.
In photosynthesis, oxygen is produced by splitting of water molecule and it is released in the atmosphere.
Thus, solar energy, carbon dioxide, and water is the right answer.
