How does mitosis differ in plants and animals?

Answers

Answer 1

Answer: Well, you are already know that cell plate in plant cells divides it in half and later it becomes a cell wall.

Answer 2

Answer: "In animal cells, the cell membrane pinches in the middle and the cytoplasm divides. In plant cells, the appearance of a cell plate shows that the cytoplasm is being separated." - Glencoe Science Book 7th Grade "Life Science"

The above refers to the division of the cytoplasm, which is called cytokinesis. Although cytokinesis accompanies mitosis, it is not strictly part of it; mitosis is nuclear division.

*

In animal cells there is an organelle, the centriole, which is not found in plants. The centriole divides in two during prophase, and each daughter-centriole moves to a position that will be one pole of the spindle.

However, the centriole is not essential for mitosis in animal cells, and plant cells do not have one.

The term "microtubule organizing center" (MTOC) is used for any structure that forms the spindle. It is not yet clear what the MTOC is in plants.

A student pushes against a tree with a force of 10 newtons (N). The tree does not move. What is the amount of force exerted by the tree on the student?1) 0 N
2) 5 N
3) 10 N
4) 20 N

Answers

The amount of force exerted by the tree on the student is 10 N

Given that,

A student pushes against a tree with a force of 10 newtons (N). The tree does not move.

Based on this, we can say that

The amount of force should be same as each & every action should be equivalent & in the opposite reaction as the newton third law of motion.

Therefore we can conclude that The amount of force exerted by the tree on the student is 10 N

10 newtons (N). If the tree had less, it would be pushed. If it had more, it would push the kid (not possible).

A scientist wants to make a dna fingerprint and she has used polymerase chain reaction pcr and restriction enzymes. What should her next step be

Answers

The first step will be amplifying the DNA sample using the PCR machine. Only small sample may be used for DNA fingerprinting. the DNA is being amplified by a way f heating so as it can denature to single-stranded where tag polymerase is being synthesized by an enzyme.

step2. Take the restriction enzyme then and also the product then mix them together.

step3. by use of gel electrophoresis you learn the sample.

step 4. both results for the fingerprints and the ones you were testing so as to find if there is any banding.

She should amplify the DNA sample with the PCR machine
Mix the product with the restriction enzymes.
Run the sample on a gel electrophoresis and
compare the result with that of the fingerprint to find a match in banding
