Answer:
-involve cell division
-meiosismakes haploid cells(23 chromosomes) while mitosis makes diploid cells (46 chromosomes)
Answer:
c. number and variety of organisms vs. changing environment
Explanation:
In an ecosystem populations are in dynamic equilibrium with each other, for when a population decreases the population of its predators also decreases, because the various populations are dependent on each other for survival. What we can understand from this is that the diminishing population of a species has caused a change in the environment, making that environment unsuitable for the predator population.
In other words, dynamic equilibrium occurs when the size of a population of a species varies with changes in the environment in which they live. For this reason we can state that the number and variety of organisms vs. changing environment best indicates the dynamic balance of an ecosystem.
The answer is <span>Take consistent amounts of saliva samples from a number of people who have not eaten in 8 hours and measure the quantity of amylase in each sample.
First, the researcher needs to know the quantity of amylase in the <u>same</u> amount of saliva. Thus the amount must be consistent and not varying.
Next, people must not eat in 8 hours, so they are all in the same condition at the moment of collecting saliva. If some eat immediately before the sample collecting while some eat 8 hours before, the content of their saliva will be different.
For the correct results, all conditions must be the same.</span>

To find the functional connection's purpose in <em>A. thaliana's</em> chromatin, transcription, and splicing. It was studied and evaluated with the RNAPII processivity (involvement of TFIIS), chromatin structure (roles of BRM, SWI3c, and H1.3 in AS), and spliceosome formation were all investigated at three separate levels (characterization of the role of spliceosome disassembly factor NTR1 in the selection of splice sites).
The alteration of RNAPII elongation rate as the mechanism for NTR1 and TFIIS influences splicing.
Lack of NTR1 causes both localized lower RNAPII levels at those splice locations as well as defective splicing. This can be translated as quicker transcription elongation over those sites in accordance with the kinetic concept of transcription/splicing coupling.
