The hydrolysis of atp and preparation for reattachment to the thin filament by the myosin head called the recovery stroke.
<h3>What is myosin ? </h3>
Myosins are a class of motor proteins well recognized for their functions in the contraction of muscles and a variety of other eukaryotic motility processes. They are ATP-dependent and in charge of motility based on actin. By Wilhelm Kühne, the first myosin was identified in 1864.
<h3>When the myosin pulls the actin what is happening?</h3>
The actin is drawn along by the myosin head as it advances in the direction of the M line. The filaments migrate nearer the M line by around 10 nm as the actin is tugged. The power stroke is the name given to this motion because it is where force is generated.

It would take roughly 5 seconds knowing that sound travels 310 meters per second
Because Thymine is "replaced" with Uracil, the corresponding RNA Code for AAT would be UUA.
Answer:
Answer:
Genotype Phenotype
SS 1/4 Short hair 3/4
Ss 2/4 Short hair 3/4
ss 1/4 Long hair 1/4
Explanation:
Both are heterozygous for the trait so we can expect that the cross would be:
Ss x Ss
S s
S SS Ss
s Ss ss
So the resulting off-spring would have the following genotype and phenotype:
1 out of 4 will have a genotype of SS.
2 out of 4 or half will have a genotype of Ss.
1 out of 4 will have a genotype of ss.
But because short hair is dominant the phenotype ratios would differ because Ss and SS would express short hair, so we add up their ration:
Short hair: 1/4 + 2/4 = 3/4
Long hair: 1/4
So in summary:
Genotype Phenotype
SS 1/4 Short hair 3/4
Ss 2/4 Short hair
ss 1/4 Long hair 1/4

In the family tree below, people with the recessive trait of attached earlobes are shaded gray.
What must be true about the person labeled "A"?
A. It is a male with at least one dominant allele.
B. It is a male with two dominant alleles.
C. It is a female with at least one dominant allele.
D. It is a female with two dominant alleles.
<h2><u>Answer:</u></h2>
Its a male with atleast one dominant allele.
Option A.
<h3><u>Explanation:</u></h3>
The gene for the attached earlobe is recessive while the gene for the free earlobes is dominant. In the phylogenetic tree, we can see that both the father and mother aren't having attached earlobes. So both of them are having atleast one dominant allele which makes them have free earlobe.
In the F1 offsprings, one of the female and a male is having free earlobes. So both of them have atleast one dominant allele. The 2nd female is having an attached earlobe. So both the recessive allele have come form one parent each. So both of them are heterozygous.
Thus, the male marked as A atleast have one dominant allele. He can be a homozygous dominant, but the probability is 25%.
