Answer:

Option (C)

Explanation:

The color of the stars is very important as it is directly related to its surface temperature. The extremely hotter stars appear to be bluish in color and the less hotter stars appears to be reddish or yellowish in color. The temperature of hot bluish stars ranges from 10,000 K to 50,000 K. The sun's surface temperature is inversely proportional to the wavelength of lights. The blue stars are comprised of lights that peaks at shorter wavelengths and have extremely high temperatures. On the other hand, the yellow stars are comprised of lights that peaks at longer wavelengths and have a comparatively lower temperature.

Thus, the stars that are bluish in color are of high intensities compared to the yellow stars.

Hence, the correct answer is option (C).

When two genes from two different people are sequenced and aligned, it is discovered that there are multiple sequence difference

SSSSS [86.1K]

Answer:

The mutations lie at locations where they don't affect protein sequence due to degeneracy of the genetic code.

Explanation:

Genetic code is the set of the triplet codons each of which code for a specific amino acid. The nucleotide sequence of mRNA is read in the form of triplets during the process of protein synthesis and the respective amino acid is added to the growing polypeptide chain. The genetic code is degenerate. This means that more than one triplet code specifies one amino acid and some amino acids are encoded by more than one codon.

For instance, genetic codes CUU, CUC, CUA, CUG specify amino acid "leucine". Therefore, any change in the DNA sequence that replaces one code for the leucine with another would not affect the amino acid composition of the protein. This would result in the synthesis of proteins with the same amino acid sequence from both the wild type and mutated genes.

S phase
M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs. The cell grows (more...) The duration of these cell cycle phases varies considerably in different kinds of cells.

6. Endocrine glands ________. a. secrete hormones that travel through a duct to the target organs b. release neurotransmitters i

grandymaker [24]

Answer:

The correct answer is option C. secrete chemical messengers that travel in the bloodstream.

Explanation:

Endocrine glands are organ or gland that secrets hormones that are chemical messengers travel through the bloodstream instead of the duct. There are several glands that are part of the endocrine system such as the thyroid gland, pancreas, hypothalamus, and others.

These chemical agents are the travel through the blood and act on the site of action.

Thus, the correct answer is option C. secrete chemical messengers that travel in the bloodstream.
