<span>The two scientists, who are credited with creating the first accurate model of DNA are JAMES WATSON and FRANCIS CRICK. The success that these two scientists achieved concerning DNA structure is based on the works of other scientists, who have carried out series of research on DNA. The real proof of Watson - Crick model for DNA was released in 1982, this was after the B form of DNA was crystallized and its X ray pattern was solved.</span>
I don't get it either I just want the brainy points lol
Explanation:
The answers are: C D E. Cells are semi-permeable which means it chooses what nutrients and h2o to enter and excretes cell waste into the bloodstream.
Answer:
C
Explanation:
If the population is in equilibrium, the allele frequencies will be constant.
There is nothing about the heritability of dominant or recessive alleles that make dominant ones any more likely by nature. This rules out choices A and B.
Genetic drift mentioned in D refers to alleles leaving a population. Nothing like this was mentioned in the question, so count that answer out.
C is the only remaining answer by process of elimination. It is also the most logical choice. Directional selection refers to a process of natural selection wherein extreme phenotypes (notched leaves, or non-notched leaves) are favored. In this case, there may be some external pressure causing notched leaf plants to be more evolutionarily fit, meaning that they survive long enough to reproduce more and increase allele frequency of the dominant allele.
