The correct answer is C. Estivation

Explanation:

In biology, estivation refers to a lethargic state that is mainly prompted by high temperatures, different from hibernation that occurs in the winter or at low temperatures. However, as hibernation estivation implies the organism of animals lowers the metabolic rate with the purpose of avoiding to die due to the high temperatures and the lack of resources including water. This can occur in both vertebrate and intervertebral animals including small animals. This implies, the mouse described which is a small animal probably is going through estivation as due to hot temperatures the organism lowers the metabolic rate, which is exactly what occurs in this process.

A true-breeding plant with green pods and wrinded seeds is crossed with a plant that is heterozygous for both traits. Drawa

AlekseyPX

The possible genotype would be when one of the parent is homozygous dominant - Phenotype ratio= 16:0, genotype ratio= 1 YYRR : 1YYRr: 1 yYRR: 1 YyRr.

when one of the parent is homozygous recessive the phenotype ratio is 4 yellow and round : 4 yellow and wrinkle : 4 green and round : 4 green and wrinkle and genotype ratio = YyRr: Yyrr: yyRr: yyrr or

1:1:1:1 genotype ratio.

Explanation:

The data given:

yellow and round dominant --- Y R

Green and wrinkle recessive ---- yr

It is given a true breeding plant, which means the parent plant is homozygous for the trait. Let one of the parent be YYRR

Also it is given that it was crossed with heterozygous parent so the other parent be YyRr

The cross between them is shown in punnet square as:

YR Yr yR yr

YR YYRR YYRr yYRR YyRr

YR YYRR YYRr YyRR YyRr

4 YYRR: 4 YYRr: 4 YyRR: 4 YyRr

thus genotype ratio is 1:1:1:1

phenotype ratio all 16 are yellow and round.

In case when either parent is homozygous recessive is crossed with heterozygous parent. The punnet square for this is shown as:

yyrr X YyRr

YR Yr yR yr

yr YyRr Yyrr yyRr yyrr

4 YyRr: 4 Yyrr: 4yyRr: 4yyrr

1:1:1:1 genotype ratio

phenotype ratio = 4 yellow and round : 4 yellow and wrinkle : 4 green and round : 4 green and wrinkle.

Thus phenotype ratio is 1:1:1:1

Describe the two stage life cycle of plants: the gemetophyte stage and the sopophyte stage

Bad White [126]

Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle.
