Answer:
The statement that is least true of an endocrine gland is d. all hormones are steroids.
Explanation:
The endocrine glands are a set of glands that are devoid of excretory ducts (they are ductless glands), produce and release hormones (messenger substances) directly into the bloodstream. The hormones can be steriodeas, produced by endocrine cells from cholesterol and non-steroids, synthesized from amino acids (Proteins, peptides, glycoproteins, derived from simple amino acids)
I think it’s thermosphere :)
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
