The answer is NO. This is because different environments require different adaptations. A desirable trait in one environment may be inconsequential or detrimental in another environment. This is the reason also why evolution is continuous as natural selection acts on traits of a population to ensure desirable traits are retained with changes in the environment in a dynamic world.
Answer:
Explanation:
In a lake, oxygenic phototrophs produce new organic material as well as O₂. If primary production rates are very high, the resultant excessive organic matter production can lead to bottom-water O₂ depletion from respiration and the development of anoxic conditions. This in turn stimulates anaerobic metabolisms, including anaerobic respirations and fermentations.
Organic matter that is not consumed in surface layers sinks to the depths and is decomposed by anaerobes.
When alleles are recombined during sexual reproduction, they can produce dramatically different phenotypes. Thus, sexual reproduction is a major source of variation within many population. Asexual<span> production is when there is one parent that produces offspring that are identical to the parent. Basically a copy of the parents DNA.
Your answer in short is B

Answer:
PP = 25%
Pp = 50%
pp = 25%
Explanation:
Using punnett square, we can predict the percentage probability of genotypes.
P p
P PP Pp
p Pp pp
In this cross we have,
PP = 1/4 = 25%
Pp = 2/4 = 50%
pp = 1/4 = 25%
We have ratio,
1 : 2 : 1
