Correct Answer: Inbreeding
Explanation:
Self pollination occurs in the flowers when the pollen grains of the flower falls on the stigma of the same due to wind or insects like moths and bees. This lead to the inbreeding.
Correct Answer: TRUE
Correct Answer: Hypertonic environment
Explanation:
Salts and sugars work to preserve foods by creating a Hypertonic environment.
Correct Answer: Some alleles are dominant, while others are recessive
Explanation:
The principle of dominance states that some alleles are dominant, while others are recessive.
Correct Answer: TRUE
Explanation:
ACTH means Adrenal Corticotrophic Hormone.
CRH - Corticotrophin Releasing Hormone produced by hypothalamus stimulates the pituitary gland to release the ACTH which in turn produces corticosteroid hormones by adrenal glands.
Hence, the given statement is TRUE.
