Mitosis and meiosis are the two ways by which cells reproduce. As a result, they share several steps in their respective processes. Meiosis adds another division and a step that mixes the genetic material, but in both cases the cell must duplicate its DNA, pull it apart into two sets, place the sets on each end of itself, and then divide down the middle. Both mitosis and meiosis produce fresh new cells based on their parent cells' genes.
Answer:
<em>Test group is a group that is modified or </em><em>changed by the researcher </em><em>and is then compared to the </em><em>experimental group while carrying out an experiment. </em>
Explanation:
While observing the data of the test group, it has to be compared with the control group to see if there is any effect of the treatment on the test or not. The control can be positive or negative or both to which the test group is compared.
As the individual body size of an organism increases, the population density for this organism in a given habitat tends to decrease.
<span>It has been shown that an inverse relationship between the size of an animal and its local abundance exist. Animals with larger body size have higher energetic requirements, resource exploitation, and susceptibility to predation and thus the competition is bigger. Yet, the density–body size relation depends on the physical complexity of the habitat and population of a species.</span>
Question: Please use the following information to answer the question(s) below. A group of six students has taken samples of their own cheek cells, purified the DNA, and used a restriction enzyme known to cut at zero, one, or two sites in a particular gene of interest.
Analysis of the data obtained shows that two students each have two fragments, two students each have three fragments, and two students each have one only. What does this demonstrate?
Answer:
"The two students who have two fragments have one restriction site in this region."
Explanation:
A restriction enzyme, restriction endonuclease, or restrictase is an enzyme that cuts DNA into trashes at or close precise appreciation sites inside particles identified as restriction locations. Restriction enzymes are one session of the wider endonuclease collection of enzymes. In the laboratory, restriction enzymes (or restriction endonucleases) are used to cut DNA into minor trashes. The scratches are constantly made at exact nucleotide arrangements. Unlike restriction enzymes recognise and cut diverse DNA sequences.
Temperature can cause an enzymes shape and function to alter due to the fact that once an enzyme reaches its optimum level, if it goes over it begins to denature. If the temperature is below optimum, then an enzyme will work at a slower rate. Also, the pH can affect an enzyme.
