If you used a radioactive label to trace the pathway of carbon through cell respiration, the label would begin in glucose and en in co2. TRUE
Cells produced at the end of telophase II have half as many replicated chromosomes as cells that started the process.<span>Telophase I is the stage double stranded chromosomes arrive at poles of each cell.</span>
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>
Answer:
b. genes have no difficulty crossing the species barrier.
Explanation:
DNA is a universal molecule, by now it is known that has the same structure in pigs, birds, an other living things.
When a gene is transfer to other species, the most difficult action is that the living thing that is the receptor, can adopt this new sequence of DNA and reproduce it again as part of the new DNA.
In some examples like in pigs and humans, we are so closely that you can use some DNA pigs or tissues to replace in humans when is neccesary in a surgery.
Answer:
chitin and murein
Explanation:
The chemical compounds that distinguish bacteria cell from yeast cell are
chitin and murein
Chitin is a polysaccharide present in the exoskeleton of fungi made up of chains of modified glucose known as N-acetylglucosamine. N-acetylglucosamine is derived from glucose
While murein is a mesh like structure made up of sugar and amino acids. Murein forms a layer outside the plasma membrane of bacterial cell.
