<span>D is the correct answer. Coral reefs need sunlight to grow, so they grow best in shallow water (up to 50m deep) as this means sunlight can reach them. They require salt water to grow and warm temperatures of 20 - 32 degrees Celsius.</span>
Answer:
B. A sperm cell
Explanation:
Meiosis creates gametes/sex cells, such as the sperm and egg.
So, sperm cells are formed by meiosis.
Meiosis doesn't create fertilized eggs, it instead creates normal egg cells.
Meiosis also doesn't create heart and bacterial cells because those are made in mitosis.
So, B is the correct answer.
The fourth one that looks like an M. This is because it describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups.
A.DNA
B.RNA
C.DNA
D.RNA
E.RNA
F.DNA
Explannation : RNA has not T
Answer:
DNA strand = complementary strand
GCAAG = CGTTC
TTACG = AATGC
GATAC = CTATG
CGGAT = GCCTA
DNA strand = mRNA strand
CGATT = GCUAA
GCTTA = CGAAU
GCATC = CGUAG
TTCAT = AAGUA
Explanation: A complementary strand is not the same in base composition and sequence with the template strand. In DNA, anywhere adenine is found in the template strand, thymine is found in the complementary strand and anywhere cytosine is found in the template strand, guanine is found in the complementary strand. But in RNA, anywhere adenine occurs in the DNA template strand, uracil occurs in the mRNA strand, wherever thymine occurs in the DNA template strand, adenine occurs in the mRNA strand and wherever guanine occurs in the DNA template strand, cytosine occurs in the mRNA strand.
Summarily, in DNA adenine pairs with thymine while cytosine pairs with guanine while in mRNA, adenine pairs with uracil, while cytosine pairs with guanine.
