Answer:
To recieve information and control functions
Explanation:
I positive that the answer id D why because Without<span> them the Earth </span>would<span> be too cold for us, or any other living thing, to survive. Naturally occurring </span>greenhouse gases<span>, such as carbon dioxide and methane, allow solar radiation to reach the Earth's surface, while trapping radiation from the Earth on its way back out to space.

Answer:
The respiratory system as well as circulatory system (hormonal system) are involved in controlling the negative feedback of our body.
Explanation:
The respiratory system helps in controlling the negative feedback in such a way that if CO2 level increases in body the system acts in such a way so as to decrease its level in body . the system attains a normal level by increasing the blood circulation and increasing the breathing level forcing CO2 outside of our body.
in case of circulatory system, the blood has several hormones released from glands . the most common example is Insulin and Glucagon .
if a person is hypoglycemic then glucagon concentration increases and blood glucose concentration returns to normal and if a person has hyperglycemia then insulin level increases which in turn increases glucose uptake from body and body returns to normal level.
They can study the number and organization of operons by reading the genome sequence.
Answer:
C. The green allele is recessive to the yellow allele
Explanation:
Complete dominance occurs when one gene variant or allele referred to as the 'dominant allele' completely masks the expression of another allele referred to as the 'recessive allele' in heterozygous individuals, i.e., in individuals carrying one copy of the dominant allele and one copy of the recessive allele for a particular locus/gene (whereas homo-zygous individuals carry the same alleles for a given locus/gene). Mendel crossed pure lines of pea plants, i.e., homo-zygous lines for different traits such as seed color (yellow and green) and seed shape (round and wrinkled). In this case, the parental cross was YY x yy, where the 'Y' allele is dominant and encodes for yellow seed color, and the 'y' allele is recessive and encodes for green seed color. From this cross, Mendel obtained a hybrid F1 (i.e., all progeny was heterozygous with genotype Yy). An expected 3:1 ratio as observed in this case (6,022 yellow and 2,001 green seed >> 3:1 ratio) is characteristic of the progeny that results from mating between F1 heterozygous parents, where each parent has one dominant allele and one recessive allele, i.e., F1 parental cross: Yy x Yy >> F2: 1/4 YY (yellow color); 1/2 Yy (yellow color); 1/4 (green color) >> 3:1 ratio of yellow to green seeds.
