<span>The answer is molecular clocks.

Molecular clocks use rates of mutation to measure evolutionary time. This technique is based on the fact that mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages and vice versa.</span>

Mendel's law of______ governs which allele is expressed in an individual.​
allsm [11]

Answer:

Mendel stated that each individual has two alleles for each trait, one from each parent. Thus, he formed the “first rule”, the Law of Segregation, which states individuals possess two alleles and a parent passes only one allele to his/her offspring. One allele is given by the female parent and the other is given by the male parent.

Why doesnt your dna look like the double helix model that Watson &amp; Crick discovered?
LenKa [72]
<span>Everyone’s DNA are different because they are different people. One part of DNA are your genes. The genes are what you look like, hair color, eye color, everything that you can get from your parents. Even if you have a twin, it’s not necessary that you two would have the same genes. For example, one could have green eyes and the other could have brown eyes.

A rock can be highly permeable but also non-porous. <br> True <br> False
vekshin1
<h3><u>Answer;</u></h3>

The above statement is <u>false</u>

<h3><u>Explanation</u>;</h3>
  • Rocks have different porosity and permeability characteristics, which means that water does not move around the same way in all rocks below ground.
  • Permeability greater than 250 mD are considered very good, while permeability less than 1 mD are considered poor.
  • Low porosity normally results in low permeability, but high porosity does not necessarily imply high permeability. It is possible to have a highly porous rock with little or no interconnections between pores.

Describe pulmonary circulation

Answer:

Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.
