Answer:
The science of biology explains the origin and persistence of life, and studies the changes in living things
Explanation:
The answers to this question are the following:Base- pairing rule where RNA was made where the U strand being paired with A-strand and the C strand being paired to G-strand in transcription within the nucleus. This is done along with the strong strand in "DNA."
The answer in the first line is "Base-pairing rule" while in the second line is "DNA"
They attach to the membrane at specific receptor sites. Once attached the virus injects its DNA or RNA into the cell. Enveloped viruses are enclosed in a membrane similar to that of the host cell. The virus and the envelope fuse and the virus enters the cell through endocytosis. To make it easier viruses hijack a cell then they inject their genetic material into the cell and try to take over then it uses the cell to make more
Answer:
A. VG = 80
B. Broad sense heritability = 0.80
C. Narrow sense heritability = 0.30
D. Average yield = 430 Units
Explanation:
A. Given that
VA = 30
VD = 50
VI = assumed not available
Therefore
Total genetic variance (VG) = VA + VD
= 30 + 50
= 80
VG = 80
B. Given that
VP = 100
VG = 80
Broad sense heritability, H2 = VG/VP
= 80/100
= 0.80
C. Given that
VA = 30
VP = 100
Narrow sense heritability, h2 = VA/VP
=30/100
= 0.30
D. The difference in selection = 500 - 400
= 100
Recall,
Selection response is heritability multiplied by selection differential.
That is
R = h2S
Selection differential = 100
Heritability h2 = 0.30
Selection response = 0.30 × 100
= 30units
Therefore, expected average yield = 400 + 30
= 430 Units
Answer:
C
Explanation:
C the order of the three nitrogen bases in a DNA molecule
