How does mitosis differ in plant and animal cells? How does plant mitosis accommodate a rigid, inflexible cell wall?

Biology
1 answer:
yarga [219]2 years ago

Answer:

All manifestations of mitosis noted so far occur in animal and plant cells, and there are two differences between them. Astral and anastral mitosis: In astral mitosis, the centrioles of the animal cell are involved in the fibers of the aster. Anastral mitosis, on the other hand, is when we don't find both centrioles and asters in plants.

The other difference is Cytokinesis: In animal cells, since there is no cell wall, there is a strangulation of the plasma membrane, and cytokinesis is called centripetal. In plant cells, due to the presence of a cell wall, it is not possible to have a strangulation division. What occurs is an agglomeration in the equatorial region of vesicles originated from the Golgi complex. These vesicles unite, forming a thin strip, separating the daughter cells. After this process, the synthesis of the cell walls extends from the center to the periphery, under the name of the centrifugal division.

Why is the cell theory a theory and not a law?. A. The cell theory describes the natural world.. B. The cell theory explains the
anzhelika [568]

The correct answer is C.
Cell theory is a theory, not a law because the cell theory does not have enough support to become a law.
 Cell theory is referred to as the history of scientific theory. All cells come from pre-existing cells, and that is the basic unit reproduction and a basic unit of all organisms. The three tenets of cell theory are,
 1. cells arise from pre-existing cells.
2. The cell an organizational basic unit and structure in organisms.
3. All living organisms are composed of more or one cells. Cell theory did not become a law because the scientist who discovered it, did not give it a credit to become a law but a theory.
Since it did not have enough support to become a law.

Leonardo is a five-year-old boy. While playing on the shore, he threw an empty, capped, plastic bottle into the waves. What do y
Orlov [11]

Answer:

B: I saw it an hour ago and I didn't want to answer because there are too many ifs. I tried, but it could be wrong.

Explanation:

This is not as simple as it sounds and I have a feeling that the correct answer is in the head of the person designing the question. In other words, I could easily get it wrong.

It depends on whether the tide is going in or going out to start with. The question would be a whole lot easier if the bottle was dropped miles from shore.

A: The bottle is capped. A is certainly not true. The low density of the bottle will keep it afloat until something happens that determines it's permanent direction. Not A.

B: It will if nothing else influences it. There will always be waves around that will insure an up and down movement. This is a possible answer, but not a certain one. A five year old could not throw it very far to start with. Let's read the rest.

C: Maybe. It has happened. The bottle needs a good start and the tide going out to happen.  Let's read the last 2.

D: Not in a million. Not D.

E: It won't be still. The ocean is always moving. Not E.

I'm going to pick B, but it is not a slam dunk.

Ymorist [56]

Answer:

The normal body temperature for humans is 37 degrees Celsius. Most of the enzymes of a human's bodywork best at this temperature. If an enzyme was discovered which works best at 39 degrees Celsius, then it means that the enzyme works at elevated temperatures for events which require slightly higher temperatures.

The enzyme will most probably work for overcoming fever or for reducing the temperature of the body after exercise.
