soldier1979 [14.2K]

Answer:

The correct answer is option 3. a nucleus.

Explanation:

The first genetic material present in the early organisms were RNA which was present in the microscopic organisms back then 3.5 billion years ago which means it is normal to have RNA in such microfossils chemical analysis.

Since, the nucleus was not present in early life forms of prokaryotes like bacteria. so, it is unusual to find nucleus in the fossils of stromatolite rocks.

Thus, option III is the correct answer.

erik [133]
<h3><u>Answer;</u></h3>

It occurs over many generations.

It happens at the genetic level.

<h3><u>Explanation</u>;</h3>
  • <em><u>Evolution is the process that involves change in the inherited traits of a population over generations. </u></em>
  • <em><u>The traits involved are the expressions of genes that are copied and passed from the parents to the offspring during reproduction process. Mutations in these genes results to new traits and thus heritable differences among organisms.</u></em>
  • <em><u>Therefore, evolution will only occur when there is change in gene frequency within a population over a given period of time. Genetic differences that are heritable are passed to the next generation.</u></em>

Which statement BEST supports the choice made in Part A? A The diagram shows four daughter gametes that have exchanged genetic i
lesantik [10]

A statement which best supports the choice made in Part A (independent assortment) is: C. The diagram shows four unique gametes that are the result of two chromosomes separating in different ways.

<h3>Mendel's law of independent assortment.</h3>

Mendel's law of independent assortment is a theory which states that the alleles of two or more different genes are sorted into unique gametes that are independent of each another.

This ultimately implies that, the allele that is typically being received by a gamete for one gene doesn't influence or affect the type of allele that is received for another gene.

Based on the biological process (independent assortment) shown in the image attached below for part A, we can infer and logically deduce that a statement which best supports the choice made is that he diagram shows four unique gametes that are the result of two chromosomes separating in different ways.
