How does the enzyme present in the globular myosin head play its role during muscle contraction​
kifflom [539]

In addition to binding actin, the myosin heads bind and hydrolyze ATP, which provides the energy to drive filament sliding. This translation of chemical energy to movement is mediated by changes in the shape of myosin resulting from ATP binding.

Between a Black father bear (genotype BB) and a Brown mother bear (genotype bb), they had several baby bears.Black fur allele (B
Karolina [17]

Answer:

100% or 1

Explanation:

This question involves a gene coding for fur color in bears. According to the question, black fur allele (B) is dominant over the brown fur allele (b). This means that a bear heterozygous for fur color (Bb) will be phenotypically black.

In this question, a black father bear (genotype BB) and a brown mother bear (genotype bb) were crossed, the baby bears will all have a genotype Bb (see punnet square in the attached image). Since all the offsprings of this cross have genotype Bb, this means that 100% will have black fur.

Calculate the population. There is a flock
laiz [17]

Answer:

C. Population shrinks; 15 birds in  the end

Explanation:

Let us understand some of the given terms;

  immigration is a form of migration in which organisms comes into a territory.

  emigration is a form of migration in which organisms leaves a place

 population is a group of organisms of the same species

Given:

Population  = 21 birds

Immigrant = 3 birds

Emigrants  = 9 birds

 Population change = total number of birds + immigrant  - emigrants

                                   = 21 + 3 - 9

                                     = 15 birds

The population will shrink giving 15 birds in the end

Cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called _____.
Montano1993 [528]

Cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.

<h3>What are prokaryotic cells?</h3>

Prokaryotes are organisms whose cell (or cells) are characterized by the absence of a nucleus or any other membrane-bound organelles.

Prokaryotic cells are opposed to their eukaryotic counterparts that possess a membrane-bound nucleus that houses their genetic material (DNA).

Examples of prokaryotes are as follows:

  • Bacteria
  • Archeaebacteria

Therefore, cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.

Phosphorus is required to synthesize the deoxyribonucleoside triphosphates used in DNA replication. A geneticist grows some E. c
Harlamova29_29 [7]

Answer:

<h2> After one round: one strand of DNA  will contain radioactive 3232P, while the other strand  will not contain any radioactive phosphate. </h2><h2> After two rounds:  here 50%  of DNA will have 3232P in both strands, while 50% will contain 3232P in one strand and nonradioactive in the other strand. </h2>

 

Explanation:

1. In the initial sample which is immediately removed after addition of radioactive isotope of phosphorus ( 3232P), hence there is  no incorporation of 3232P into the DNA because replication in the medium containing 3232P has not yet occurred.  

2. After one round of replication in  radioactive isotope of phosphorus ( 3232P) containing  medium, here  only one newly synthesized strand of DNA molecule will contain 3232P, while the other strand  will not contain any  radioactive isotope of phosphorus ( 3232P),  because DNA replication occurs in semi-conservative way.

3. After two rounds of replication in medium which contains radioactive isotope of phosphorus ( 3232P), here 50% of the DNA molecules will have  radioactive isotope 3232P in both strands, while the rest 50% will contain 3232P in only one strand and nonradioactive phosphorous in the other strand.
