Describe one type of factor that controls cell division.

1 answer:

7 0

The cell cycle is controlled by many cell cycle control factors, namely cyclins, cyclin-dependent kinases (Cdks) and cyclin-dependent kinase inhibitors (CKIs). Cyclins and Cdks, which are positive regulators of the cell cycle, activate cell cycle factors that are essential for the start of the next cell cycle phase.

Factors Affecting Cell Division
Nutrients. The nutrients present in the cell affect cell division. ...
Genetics. Genetic code regulates cell division. ...
Chemicals. Exposure to toxic chemicals such as pesticides and some cleaning chemicals can cause cell mutation. ...
Stress. Stress affects cell division.

CR endurance is determined by a. the amount of oxygen the body is able to utilize per minute of physical activity. b. the length

Amanda [17]

Answer:

The answer is A.

Explanation:

The CR endurance that is given in the question, or cardio respiratory endurance, can be described as the heart's, the muscles' and the lungs' ability to be able to work together effectively through extended periods of physical activity and it can be determined by measuring the amount of oxygen that the body uses in a minute during the said physical activity.

I hope this answer helps.

What are the chances a heterozygote passes on either a dominant or recessive allele?

melisa1 [442]

Answer:

A parent with one copy of a dominant allele and one recessive coded Ww for the widow's peak is called heterozygous for a trait and has a 50 percent chance of passing on the dominant allele to each of his or her offspring, regardless of the gene inherited from the other parent.

This type of membrane transport moves substances against the concentration gradient from an area of low concentration to an area

sashaice [31]

Answer:- Active transport

Explanation:-

There are two types of membrane transports

1. Passive transport - this type of transport occurs without the input of any energy and the molecules move along the concentration gradients that is from high concetration to low concentration.

2. Active transport- this type of transport takes place to move the molecules against the concentration gradient that is from low concentration to high concentration.

The active transport is of two types:

1. Primary active transport- in this type of transport ATP is used as an energy source to move the substances against the concentration gradient.

2.Secondary active transport - in this type of transport the gradient formed by the active transport is utilized and it involves the movement of 2 substances at a time aross the membrane. That is the movement of one molecule is coupled to another.

The membrane proteins that are associated with active transport are called as carrier proteins. These proteins have a binding site for the molecules that they transport. Once they bind to the specific molecules, a conformation change is induced and this leads to the transport of the molecule across the membrane.

So, the active transport is basically responsible for utilizing the energy from ATP and carrier proteins to move the substances across the membrane against their concentration gradient i.e. from low concentration to high concentration.
