When the data in an investigation does not support the original hypothesis, you can modify your hypothesis to support the experimental data. However, you should NEVER change your experimental data to fit your hypothesis.

The hypothesis is an educated, which is based on the researches done in the past and are well established. The hypothesis is a guess, which is testable. The experiments based on the hypothesis are performed and the data is collected. In case, the data obtained from the experiment does not match the hypothesis then the hypothesis may not be valid, hence, the hypothesis needs a revision in such cases.

Which area of biology states that living things undergo gradual, structural, and functional changes over long periods of time

Tasya [4]

Given what we know, we can confirm that the area of biology that states that living things undergo gradual, structural, and functional changes over long periods of time is referred to as evolution.

<h3>What we know about evolution. </h3>

This is a theory that was put forward by Charles Darwin.
Evolution accounts for the structural and functional changes that are passed down from one generation to the next.
The changes produced by evolution are very slow in that they may take many generations to complete a noticeably change.
These changes are hereditary.

Therefore, we can confirm that the theory of evolution put forward by Charles Darwin states that living things undergo gradual, structural, and functional changes over long periods of time.

There are 100 cats in a population that follows hardy-weinberg conditions. 4 cats display a recessive white coat color. how many

mr Goodwill [35]

We know that Hardy-Weinberg conditions include the following equations:

$p^{2}+2pq+ q^{2}=1$

where $p+q=1$

And where p = dominant, and q = recessive; this means that $p^{2}$ is equal to the homozygous dominant, $2pq$ is the heterozygous, and $q^{2}$ is the homozygous recessive .

So we have 100 total cats, with 4 having the recessive white coat color. That means we have a ratio of $\frac{4}{100}$ or 0.04. Let that equal our $q^{2}$ value.

So when we solve for q, we get:

$q^{2}=0.04$

$q=\sqrt{0.04} =0.2$

Now that we have our q value, we can use the other equation to find p:

$p+q=1$

$p+0.2=1$

$p=0.8$

So then we can solve for our heterozygous population:

$2pq=2(0.8)(0.2)=0.32$

This is the ratio of the population. So we then multiply this number by 100 to get the number of cats that are heterozygous:

$0.32*100=32cats$

So now we know that there are 32 heterozygous cats in the population.

Beginning with a cell that just fertilized ( 1 cell ) how many times must it divide to become a 64 cell blastomere ?

natka813 [3]

A cell that just fertilized has to divide 6 times to form a 64 cell blastomere.

<u>Explanation:</u>

Human reproduction begins with the fusion of male gamete sperm and female gamete ovum. The fusion of sperm and ovum forms the zygote that is diploid. The zygote then undergoes mitotic division to develop into embryo.

The zygote first divides into two and the two individual cells divide again to form four individual cells and so on. Thus the number of cells after each division can be represented by the equation $2^n$ where n is the number of divisions. in the question it is given that the blastomere has 64 cells.

$2^n=64$

n=6

This means that the fertilized cell has to divide 6 times to develop into 64-celled blastomere.
