Answer:
Arteries carry oxygenated blood away from the heart. Veins carry the blood back to the heart. Veins contain valves that ensure blood flows in only one direction. Arteries don’t require valves because pressure from the heart is so strong that blood is only able to flow in one direction.
Explanation:
Answer: the atoms are istopes
Explanation:
Answer:
Species A: 2
Species B: 56
Species C: 162
Explanation:
Codons are sequence of 3 purine or pyrimidine bases that codes for amino acids. Each codon in mRNA eventually binds with anticodon in tRNA during protein synthesis and gets translated into their respective amino acids. Hence, the number of amino acids in each of the species represents the minimum number of codons in each species.
<em>Therefore, species A with 2 amino acids will have a minimum codon length of 2, species B with 56 amino acids will have minimum of 56 codons while species C with 162 amino acids will have minimum codon length of 162.</em>
Answer:
9/64
Explanation:
Given, AABBGG X aabbgg = AaBbGg (F1)
Resulting F1 progeny is self fertilized.
AaBbGg X AaBbGg :
If we check individual crosses:
A a
A AA Aa
a Aa aa
3/4 of the progeny will display dominant A phenotype ( AA, Aa ). Similarly,
3/4 of the progeny will display dominant B phenotype ( BB, Bb ).
G g
G GG Gg
g Gg gg
1/4 of the progeny will display recessive g phenotype (gg).
Total offspring that will display ABg phenotype =
3/4 * 3/4 * 1/4 = 9/64
