Answer:

power stroke

Explanation:

The process of muscle contraction requires several steps.
The most famous theory on how the contraction and relaxation of muscles take place is the sliding filament theory.
However, this theory has been refined and one important addition to it is the mechanism by which myosin can pull actin and cause shortening of the sarcomere.
For the movement of myosin, it binds and releases actin and forms cross bridges.
Myosin is subdivided into two regions - S1 and S2. The contraction of the S1 region is what constitutes the power stroke.
An important requirement of the power stroke is the hydrolysis of ATP to release an inorganic phosphate which provides energy for the process.

Based on what you know about the regulation of cell growth, make a list of questions you would ask as you observe the cells.

sertanlavr [38]

Answer:

1. What genes control the growth of cell growth?

2. What is the purpose of this regulation?

3. What happened when the cell growth is not regulated?

Explanation:

What genes control the growth of cell growth? What is the purpose of this regulation? What happened when the cell growth is not regulated?

Above are the questions which an observe would ask about regulation of cell growth. A number of genes such as oncogenes and tumor suppressor genes are involved in the regulation of cell growth and cell division. Regulation of cell growth process ensures that a cell's DNA which is dividing is copied properly as well as repair errors in the DNA. It also ensures that each daughter cell receives a complete set of chromosomes in order to gain healthy daughter cells.

3.6 In mice, the allele C for colored fur is dominant over the allele c for white fur, and the allele V for normal behavior is d

KengaRu [80]

Answer:

a) Parents Genotype should be (CC,Vv) and (cc,VV).

b) The genotypes of the parents are (Cc,Vv) and (Cc,Vv).

c) The genotypes of the parents are (Cc,Vv) and (cc,vv).

Explanation:

Mating has occured between a normal colored mice whose genotype is C_,V_ and normal white mice with genotype cc,V_. The offsprings are as follows :

1) normal mice produced 29 colored

2) 10 colored, waltzing progeny.

Thus all offspring are normal. The genotype of the first parent should therefore be CC. Waltzing trait is produced. The V gene should therefore be heterozygous in both traits.

Hence The parent genotypes should be<u> (CC,Vv) and (cc,CV).</u>

In this case the approximate ratio in which the descendants are produced is 9:3:3:1. Hence genotypes of the parents are <u>(Cc,Vv) and (Cc,Vv). </u>

In this case the approximate ratio in which the offsprings are produced is 1:1:1. The genotypes of the parents are <u>(Cc,Vv) and (cc,vv). </u>
