WHAT IS The 2nd phase of mitosis

Biology
1 answer:
kogti [31]3 years ago
4 0

Answer:

When prophase is complete, the cell enters prometaphase — the second stage of mitosis. During prometaphase, phosphorylation of nuclear lamins by M-CDK causes the nuclear membrane to break down into numerous small vesicles. As a result, the spindle microtubules now have direct access to the genetic material of the cell.

Uracil pairs with adenine rather than with guanine.</span><span>

Which type of muscle can be found inside organs?
inessss [21]

Answer:

The correct answer is - smooth muscles.

Explanation:

inside the organs, there are internal muscles present that build walls of most of the organs like the stomach, heart, blood vessels, intestines, and more hollow organs. These muscles are composed of ininvoluntary muscles.

These muscles can not be controlled as these are meant to be working on their own with the stimulus. The role of such muscles is to push or pull the various material such as blood, or food through the organs.

Thus, the correct answer is - smooth.

During exercise, venous return of blood to the heart increases. based on your knowledge of starling's law, what would happen to
trapecia [35]

Answer:

The stroke volume of the heart will also rise since exercise is the process where heart is working with great internal pressure or we can say it is in a state of being distended, this ultimately will cause a greater strength of contraction.

This is just in accordance with Stroke’s law that states that stroke volume of the heart increases if the volume of blood in the ventricles, before contraction if all other factors remain same or unchanged. When a large amount of blood rushes in the ventricle, it stretches the muscle fibers of heart that ultimately causes a rise in the force of contraction.  

Significance:

This actually helps in the synchronization of output from heart with arterial blood supply, venous return and humoral length without regulating or producing any other changes in the body.
