When Darwin wrote on the origin of species he assumed due to the fossil record that species would not evolve quickly since that

time evolutionary theorists have documented example of much more rapid evolutionary change now how would we explain the long periods relative consistency with little change in some species that we see in the fossil record?

If there is no reason to change (constant climate), then change won't occur. For example, a desert is basically always dry and hot with sand and few clouds. If a creature is fit for the climate, it will continue to exist until a severe enough climate change. For a real world example, in pre-industrial Europe, the birch trees were white. This permitted white moths to survive and not get eaten by the owls that hunt them, until the industrial revolution. Ash got on the birch trees, changing the color of the trees to a darker black. The white moths stood out, and therefore got eaten, permitting the black variant of the moths to thrive, where they were close to complete eradication before the revolution.

In studying the gene pool of a population, you find that 21% of the population exhibits the recessive trait for eye color and th
Naily [24]
In order to solve this problem we use these formula:
<span>p2 + 2pq + q2 = 1p + q = 1p = % dominant allele in the population
q = % recessive allele in the population
p2 = % homozygous dominant individuals
q2 = % homozygous recessive individuals
2pq = % heterozygous individualsFrom the given, we haveq2 = 21%Simply taking the square root,q = 4.58%</span>

Studies peg the number of proteins in the human body to be around 10,000 to several billions. This diversity is a result of the
Harrizon [31]

Answer:

The correct answer is - option B.

Explanation:

The diversity of numbers of proteins in the human body is due to the differences in the structure of proteins. This change or difference in the structure of proteins is mainly affected by the sequence of amino acids.

The order of sequence of amino acid segment or residue in the peptide chain of the protein affects the structure of the particular protein which also leads to change in the secondary and tertiary structure of the protein.

Thus, the correct answer is - option B.

Marissa is testing a hypothesis through experimentation. She believes that immersing ocean coral in carbonic acid will slow the
motikmotik

Answer:

The answer choices to this question are:

A) She releases cement particles into a random number of the coral samples.

B) She uses three different types of coral to establish her dependent variables.

C) She treats the coral samples identically with varying levels of carbonic acid.

D) She obtains her coral samples from coral reefs surrounding different continents.

Best Answer is:

A) She releases cement particles into a random number of the coral samples.

Theory:

It has been researched that ocean acidification caused by carbon dioxide emissions causes a decrement in the coral reef growth and this will keep slowing down unless steep and rapid reductions in greenhouse gas emissions are made. And the Coral reefs offered economic opportunities would advantage the surrounding communities from fishing and tourism.

i did this question so thats why i know the answer choices

hope this helpsss
