The correct answer is throughout all of history.

The scientific knowledge was used to know the information from the days when the life on earth started or we can say that we have the knowledge of the time when the earth was formed. We have all the knowledge, factual information and description of all the event throughout all of the history.

During the early days of deciphering the human genome, scientists were surprised to find that the number of genes appeared to be

Alekssandra [29.7K]

Given what we know, we can confirm that the aspect of nucleic acids and transcription that can help explain this discrepancy is that of alternative splicing.

<h3>Alternative Splicing.</h3>

This process allowed the cells to use a single gene for the creation of various proteins.
This process includes the separation of RNA at splicing sites to create new versions of the mRNA strand.
This helps to increase the diversity of mRNA's available and create more proteins.

Therefore, given that alternative splicing allows the cells to create multiple forms of distinct proteins from a single gene, this allowed our organisms to develop the vast number of proteins we use, without the need for a much larger genome.

When the blood glucose level decreases during a fast or between meals, the pancreas releases glucagon. Glucagon signals the live

Liula [17]

Answer:

Glucagon signals the liver to start producing glucose.

Explanation:

Glucagon signals the liver to start producing glucose from the breakdown of amino acids through gluconeogenesis process. When the glucose level decreases in the body due to fasting or starvation, the pancreas release glucagon which provides signals to the liver to produce glucose form non carbohydrates substances present in our body. This production of glucose increases the concentration of glucose in the blood and the body used this glucose for the generation of energy molecules in the form of ATP.

Lena [83]

Answer:

No, observed and expected frequencies are different.

Observed frequencies: p2 = 0.56 , 2pq = 0.375, q2 = 0.062

Expected frequencies: p2 = 0.774 , 2pq = 0.211, q2 = 0.014

Explanation:

Given frequency of recessive genotype (q2)= 14/ 1006 = 0.0139

Frequency of recessive allele s (q) = square root of 0.0139 = 0.12

Frequency of dominant allele S (p) = 1-q = 1-0.12 = 0.88

Expected frequency of homozygous recessive genotype = 0.12 x 0.12 = 0.014

Expected frequency of homozygous dominant genotype = 0.88 x 0.88 = 0.774

Expected frequency of heterozygous dominant genotype = 2pq = 2 x 0.88 x 0.12 = 0.211

Observed frequencies in population 2

Observed frequency of homozygous dominant genotype = 308 / 549 =0.56

Observed frequency of heterozygous dominant genotype = 206 / 549 =0.375

Observed frequency of homozygous recessive genotype = 34 / 549 =0.062

Observed frequencies do not match with expected frequencies.
