How are the number of chromosomes maintained during asexual reproduction?
Harrizon [31]

Answer:

<em>The number of chromosomes is maintained through the process of mitosis during asexual reproduction. </em>

Mitosis can be described as a process in which a cell divides and produces two daughter cells which are exactly similar to the parent cell. The chromosome number of the daughter cells will be the same as the parent cells. No crossing over or recombination occurs during this type of cell division. Hence, mitosis is an effective way to maintain the chromosome number of organisms which reproduce asexually.

Name two effects unbalanced forces can have on an object. Provide an example of each effect.​
stealth61 [152]

The two kinds of unbalanced forces are:

  • Net Force: Is the vector sum of all forces acting (pushing or pulling) on an object.
  • Resultant Force: is a force that alone produces the same acceleration as all those forces.

To effects that unbalanced forces have on objects are:

  • Can make an object move or stop.
  • Can speed up or slow down an object.

Here are some examples:

  • When falling out of a plane when sky diving, this is making you move faster. Then when you are using a parachute, you are slowing down.
  • A man uses force to roll down an object from the top of a hill.
