Answer:

A. by observing the formation of sedimentary rocks

Explanation:

Relative age dating does not tell us how many millions of years the rock is. It informs us that this rock is older or younger than another or if it was formed before or after a certain geological event. This is done by observing the formation of sedimentary rocks.

Relative age dating is widely used in geology and manages to bring us a lot of information about the planet's past and the formation of sediments and soil in general.

Some birds in a population have an allele for long beaks and others for short beaks. A drought has caused change in the ecosyste
valentina_108 [34]

<span>The birds with the longer beaks will be fittest in the environment post-drought because they will be able to gather resources (food) hence survive. This will enable these bords to reach reproductive again and pass down the genes. It is important to note that fitness in nature is determined by the capacity to reproduce.
</span>


<span />

<span>Natural selection will change the allelic frequency such that the allele for long neck will be more in the population while that of short beaks will reduce. This is because short beaks trait will not be able to reach reproductive age (due to starvation) because of the incapacity to gather food <span>resource hence their genes will keep reducing in the subsequent generations. 
</span></span>


<span><span /></span>

<span>Natural selection is a natural selective force that acts on a population and results to variation (differential) in the survival of the individuals in the population due to variations in phenotypes in the population. The most successful traits (phenotype that is best suited for the environment) are able to reach reproductive age, find a mate and reproduce hence leave its genes in subsequent generations</span>

Claim Evidence Reasoning. Evaluate the following claim: Meiosis is different than Mitosis.
likoan [24]

Answer/Explanation:

Yes, although they have similarities, meiosis and mitosis are different.

<h3>Similarities</h3>

Meiosis and mitosis are both types of cell division that results in the production of daughter cells.

They go through similar processes of prophase, metaphase, anaphase, and telophase.

<h3>Differences</h3>

However, mitosis produces two genetically identical diploid daughter cells from a diploid parent cell.

Meiosis produces four genetically different haploid cells from a diploid parent cell.

There are two rounds of cell division in meiosis, and only one round in mitosis.
