<h3><u>Answer;</u> </h3>
= 3.68 g/cm³
<h3><u>Explanation;</u></h3>
Density is given by dividing the mass of a substance by its volume.
Thus; Density = mass/ volume
In this case; mass = 92 g and Volume = 25 cm³
Therefore;
Density = 92 g/ 25 cm³
<u>= 3.68 g/cm³</u>
True
Genotype determines the phenotype and if the genotypes are the same, then the phenotypes will be the same as well.
Answer:
conservative replication model
Explanation:
In their experiment, Meselson and Stahl found that the DNA duplexes present after the first round of replication had intermediate density. This occurred since the semiconservative process of DNA replication of one DNA molecule (having both strands with 15N) forms two DNA duplexes each with one parental strand (15N) and one newly formed strand (14N).
If they had found two duplexes of two different density, this would have supported the conservative replication model. In this case, the DNA replication of the parent DNA molecule would have formed two DNA duplexes. One DNA molecule would have both the parental DNA strands with 15N while the other DNA duplex would have both newly formed strands with 14N.
Oxygen plays an important/ key role in both systems.
All of them should be correct except for the upper left box of question 8. The correct genotype of the box should be WW instead of Ww.
When making a punnett square, all the results in the 4 boxes are combinations of the alleles present in the parents. The different combinations in the square are listed according to the allele on its left and on its top. For example, in question 9, the first box of the square (left upper) should be a combination of R and R, because the allele on the left side and the top (outside the box) are R and R. And the 2nd box, which is the upper right, should be Rr, because the allele on top is r and the allele on the left is R. Always put upper case in front, so the answer is Rr.
Same concept for other boxes, just match the alleles on the top of it, and the left side of it (the ones outside the box), and rearrange the upper/lower cases, and you'll get the correct answer.
