Answer:

c. There is uncontrolled cell division.

Explanation:

There is uncontrolled cell division that result in the improper functioning of a checkpoint protein in a cancer cell because checkpoint protein monitors and control the the process of cell cycle. If mutation occurs in this checkpoint protein, the cycle is no longer in control which leads to the uncontrolled cell division and we also know that cancer is a disease which occurs due to uncontrolled division of the cell.

What do we mean when we refer to a cell as differentiated?
Otrada [13]

Answer:

We mean that a cell changes to another type of cell.

Explanation:

<em>Stem cells </em>are a type of cell that has the potential to become a specialized cell, this change or differentiation, is possible thanks to the activation or deactivation of certain genes that promote (or inhibit) the expression of certain proteins that origins different types of cells (fmuscle cells, osteocytes, neurons). This differentiation happens when the cells receive cues internally ( through signals or contact between a group of cells and another or through transcription factors) or externally.

Then, a differentiated cell is a cell that had gone under the previously described process.

I hope this information is useful to you!

In an experimental study of the effect of copper deficiency on coat color in bicolored juvenile rats, the independent variable i
lana [24]

Answer:

amount of copper

Explanation:

<em>The independent variable would be the amount of copper fed into the experimental rats.</em>

An independent variable during an experiment is a variable whose value is not dependent on any other variable being measured in the experiment.

The value of an independent variable is not changed by any other variable in an experiment. In actual fact, the effect of the independent variable is being tested on other variables (dependent variables) in the experiment.

<u>Hence, in an experimental study of the effect of copper deficiency on coat color in rats, the amount of copper fed into the system of the rats will be varied and the effects of this variation on the coat color of the rats would be observed by measuring relevant variables. Therefore, the amount of copper is the independent variable.</u>

What specific key factor starts the breathing process in a newborn infant?
kvv77 [185]
Chemical factors: This is due to internal stimuli. Changes in the blood such as decrease in O2, increase in CO2 and decrease in PH cause impulse in the carotid artery which stimulates the respiratory centers in the medulla and cause breathing.

Mechanical factors: also called external stimuli. Compression of the fetal chest during delivery forces small amount of lung fluid out of the lungs. This increase in pressure in the chest draws air into the lungs.
