Chromosomes are the X looking things.  Each person has 23 i think because together it is 46.  Meiosis is when they divide to make more.  I hope this helped!! Good Luck!!! :)

Which statement accurately describes the relationship between cytokinesis and mitosis?
miv72 [106K]
I believe that Cytokenesis follows Mitosis, because cytokenesis is the actual split of the cells' membranes (after telophase)! Hope this helps

Imagine a species with three loci thought to be on the same chromosome. The recombination rate between locus A and locus B is 35
Vesnalui [34]

Answer:

<h2>Recombination rate or recombination frequency between locus A and locus C is either 2% or 50%. </h2>

Explanation:

As given,

Recombination frequency between locus A and B is 35%, means that the distance between A and B is 35 cM.

Recombination frequency between locus B and C is 33% , means the distance between B and C is 33 cM.

Therefore, if the locus C is present between A and B, then the recombination frequency between A and C would be 2%

A-----C ----------B

A---C= 2%

A----B= 35%

B---C= 33%

So, here the recombination frequency between A and C is 2%, means their distance is 2 cM.

If the locus C is as,   A---35---B--33----C ;   A-----B------C

A-----B= 35%

B------C= 33%

A-----C= 33+35= 68%

As rule, maximum frequency can not exceed 50%, as here the Recombination frequency between A and C = 50%.

The diagram below represents a change in guard cells that open and close pores in a plant) This Change directly helps to A. incr
AveGali [126]

The correct answer is option C, that is, regulate water loss.  

Guard cells refer to the cells enclosing each stomata. They assist in monitoring the rate of transpiration by closing and opening the stomata. The guard cells possess the tendency to monitor the closing and opening of stomata by changing shape. The shape of the guard cells modifies on the basis of the concentration of potassium ions and water found in the cells themselves.  

The stomatal pores get closed when carbon dioxide is no longer needed for the process of photosynthesis. The guard cells swell when movement of water takes place inside these pores, and thus, the opening of stomatal pores occurs, and as water moves out, the guard cell closes. Thus, guard cells play an essential role in regulating water loss.
