Answer:

The correct answer is conserving the energy of glucose and related molecules in chemical form that the cell can use for work

Explanation:

Glycolysis is an important process of cellular respiration.it occurs in the cytoplasm.

Glycolysis deals with the break down of glucose and formation of 2 molecules of ATP along with pyruvate.pyruvate then enter into miticondria to carry out the TCA cycle which result in the formation of ATP, NADH,FADH2 and oxaloacetate. NADH is also formed during Glycolysis.

In the final process of aerobic respiration known as oxidative phosphorylation the reducing agents such as NADH and FAFH2 are oxidized by liberating electrons and phosphorylation of ADP occurs by the energy generated by proton motive force resulting in the formation of ATP.

The so formmed ATP is a high energy compound which is utilized by our body to carry out various process such as muscle contraction ,fatty acid biosynthesis etc.

In rabbits, short hair is due to a dominant allele, S, and long hair to its recessive allele, s. Black hair is due to a dominant

Natali5045456 [20]

Answer:

SsBB x SsBB

SsBB x SsBb

Explanation:

SS- short hair

ss - long hair

BB- black hair

bb- white hair

Total the number of offspring produced = 2518+817=3335

Where 2518= short haired, black offspring SSBB or SsBb

817= Longed Hair, black offspring ssBB or ssBb

To get the offspring proportion for short hair black offspring

2518/3335×100 = 75.5%

long-haired, blackoffspring =817/3335×100 = 25%

This gives ratio of 3:1 as against the proposed dihybrid phenotypic ratio of Mendel experiment 9:3:3:1

Now, if you remember a dihybrid cross results in 9:3:3:1 phentoype ratio. That is when both parents are heterozygous for both alleles. So we can rule that out since it doesn't match our 3:1 ratio.

Since all the offspring are black , it means one parent is homozygous dominant for black and the other parent is either homozygous or heterozygous for the black allele.

Since the ratio is 3:1, for the hair length

That leaves us with the short hair. Since the ratio is 3:1, both parents are heterozygous for hair length.

Therefore, the possible parental genotype is

SsBB x SsBB

SsBB x SsBb

Niche is like a profession because everybody in our world performs a different job. Niche is somewhat defines like what you do, how you do it, where you do it and when you do it.In ecology, a niche is a term about the relational position of every species like dolphin. In where dolphin can potentially be in another ecological niche by travelling from one place to another. Profession are something like finding your specialty, your place and your niche in the world.
