Which statement correctly describes mitotic cell division?​

Answers

Answer:

Explanation:

“Although part of your question is missing, you might be referring to this full question:

Which of the following correctly describes how mitosis and meiosis are similar?

A. Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis.

B. Crossing over occurs between homologous chromatids during both mitosis and meiosis.

C. Both mitosis and meiosis produce diploid daughter cells.

D. Both mitosis and meiosis produce genetically identical daughter cells.”

The statement that correctly describes how mitosis and meiosis are similar is “Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis”.  

Mitosis and Meiosis both are classified under cell division that tends to take place in humans and certain other animals. Both Mitosis and Meiosis have both differences and similarities in the way they result in new cells with varying goals and slightly different outcomes. Some of the similarities between meiosis and mitosis are:

During both mitosis and meiosis, cells must duplicate their DNA and pull them apart into 2 sets and further place the sets on each end of itself and then divide down the middle part

Both meiosis and mitosis results in fresh new cells depending on the genes of their parent cells  

Thus, we can conclude that the statement that correctly describes how mitosis and meiosis are similar is “Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis”. Hence, option A is the correct answer.

Observe the cut ends of the flatworms using the hand lens or the dissection microscope immediately after cutting.
What do you see?
Are there distinct differences between the two ends?
Observe the cut ends of the flatworms over a period of several days. Do the flatworm halves continue to exhibit the same degree of difference that was seen right after they were cut in two?
What kinds of changes occur in the flatworms as they recover from having been cut in two?

Answers

The above question requires a personal answer about your experience with cutting flatworms. I can't tell you what you saw in this cut, but I'll show you what happens when it occurs.

First of all, you must understand that flatworms are worms with a great capacity for cell regeneration even if several pieces have been cut.

In this case, when a flatworm is cut in half, we can see the following events happen:

At the moment of cutting, the two ends of the flatworm body are equally shaped and are straight ends, without deformations.The ends will not be different if the cut is done accurately, but it may differ slightly.After several days, the ends will present some deformations and will lose the straight shape caused by the blade.Deformations are extremely similar and change similarly.When recovering from the cuts, each side of the flatworm body formed a new flatworm and they are no different, they are the same and they are completely recovered.

This is because the cellular regeneration of flatworms is very fast and allows any part of the flatworm's body to create exactly the same beings, as they have the same genetic makeup.

a skeletal muscle generates the greatest tension when it is:

Answers

Explanation:

A skeletal muscle generates the greatest tension when it is: partially stretched before being stimulated

Skeletal Muscle generates the greatest tension when the muscle is stretched to an intermediate length, by length-tension relationship.

How tension generates in skeletal muscle?

Muscle tension is highest in skeletal muscles when stretched to an intermediate length, as indicated by the length-tension relationship.

When skeletal muscle fiber contracts, myosin heads link to actin to create cross-bridges, and the thin filaments slide across the thick filaments as the heads pull the actin, resulting in sarcomere shortening and muscular contraction stress.

The amount of stress produced by a muscular contraction is determined by two factors: the number of active muscle fibers and the frequency of neural stimulation of the muscle fibers.

Therefore greatest tension generates in skeletal muscle when it is stretched to the intermediate length.

Organisms require a variety of chemical nutrients, such as NITROGENOUS, which are components of proteins, nucleic acids, and ATP. It is an essential element for life.

Nucleic acids, either DNA or RNA, contain nitrogen in the nitrogen bases of their nucleotides (i.e., Adenine, Guanine, Cytosine and Thymine, Uracil).

Adenosine triphosphate (ATP), the energy coin of the cell, contains nitrogen in its Thymine nitrogen base.
