Answer: DNA

Explanation:

According to the cell theory the all the cells carry out functions which is required for life.

This means that the cell must contain DNA. DNA is responsible for carrying the genetic information from one generation to another generation.

The genetic information provides the information for the protein synthesis. So, it is very important for the living beings and is found in every cell of the organism.

Why do plant cells have a cell wall and plant cells don’t?
Minchanka [31]
So animal cells can have various shapes, but plant cells only havethe shapes of their cell walls. That's nice for plants, because it gives them the ability to grow up and out, where they can get lots of sunlight for making their food.

In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants tohave rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change siz
Exactly why plant cell have wall and animal cell don't :-Cell walls are supporting structures that help the plant to have a fixed shape and protect it from injury. Other than that, it helps to keep the plant turgid so that it can stay firm and upright. Because when it enters a high water potential solution, as water moves in, the water exerts turgor pressure on the cell wall and the cell wall thus exerts an opposing pressure to keep water out. Hence cell wall is needed for the plant.

On the other hand, animal cells do not need to keep the structures, as they have the skeletal system to protect the organs and cushion them against any external Injuries.


This was the all information I had thank you.

Movement of the chromosomes during anaphase would be most affected by a drug that
My name is Ann [436]

Answer:

The options are missing, the options are:

A) prevents the duplication of centrosomes. B) prevents nuclear envelope fragmentation C) prevents shortening of microtubules. D) prevents attachment of the microtubules to the kinetochore. E) prevents nucleosome formation

The answer is C

Explanation:

Cell division is a characteristics of all living cells. Whether meiosis or mitosis, the chromosomes separate in the Anaphase stage. Prior to the anaphase stage is the metaphase, where spindle microtubules attach to the kinetochores of each chromosome and aligns them at the centre of the cell called METAPHASE PLATE.

Thus, since the aligning of chromosomes at the metaphase plate has to do with attachment of microtubules to chromosomes' kinetochores, the drug that will hinder movement of chromosomes to opposite poles will not stop formation of microtubules. Instead, it will prevent the formed microtubules attached to each chromosome from shortening, as it is the shortening of microtubules that facilitates the pulling apart of the chromosomes they are attached to.
