Answer:
The star is travelling away from the earth.
Explanation:
A star’s temperature largely determines its color. Stars with higher temperature have a bluish color and stars with low temperature appear red in color. But the color of star that we observe from the earth is different from its actual color.
This variation in color is due to Doppler effect. When the movement of a star is towards the earth the frequency shifts to the higher frequency region and when the movement is away from the earth the frequency of the light emitted will shift to the lower frequency region. Color of light depends on the frequency.
The color corresponding to the lower frequency region is red and color corresponding to high frequency region is blue. So when the star moves away from the earth it appears red in color.
Answer:
They appear more Blue
Explanation:
it was right this was the last question for me it is They appear more blue
of an organism from its phenotype.
Answer:
genotype of an organism from it phenotype
So many new species of Monera were discovered that the kingdom got too large and needed to be separated.
Advances in technology revealed that some species of Monera had nuclei and some did not.
Some species of Monera were found that could live in colonies rather than as single cells.
Answer:
The correct answer is the first statement.
Explanation:
The kingdom monera has been separated into 2 domains archaea and bacteria, because of differences in their structure and operation. Bacteria have simpler RNA polymerases than archaea. So, they sow similarities with eukarya in this matter.
Archaea do not posses peptidoglycan in their cell walls like bacteria. Archaea have distinct membrane lipid bonding from eukarya and bacteria.
Thus, the correct answer is the first statement.
Glycine is an amino acid coded by GGA, GGU, GGC, GGG codons. Histidine is an amino acid coded by CAC, or CAU codons. It should be known that the mRNA chain that will be encoded must always have a START codon at the beginning and a STOP codon at the end.
Frog red blood cells have a nucleus that human red blood cells don't. This is because human RBCs eject their nucleus to allow more room for oxygen-carrying hemoglobin, while frog RBCs retain their nucleus potentially for environmental adaptability.
The organelle that frog red blood cells (RBCs) have, which human RBCs do not, is the nucleus. In mammals like humans, the nucleus is ejected from the RBCs as they mature to allow more space for hemoglobin, the protein that carries oxygen.
This makes human RBCs more efficient at oxygen transport. However, many amphibians like frogs retain the nucleus in their RBCs throughout their lifespan. The exact reason why frogs retain their nuclei is not entirely known. However, it might give the cells greater flexibility in responding to changes in the frog's environment.

Why do most biologists believe that true commensalism does not exist?
an ecosystem usually has more parasites than hosts
animals of different species usually do not like to work together
the relationships are probably mutual or parasitic
animals of the same species rarely compete with one another
Answer:
its not host or partner the answer is parasite.
