Answer:
A - Hypothalamus and Antidiuretic Hormones
Explanation:
Whenever their is a sudden change in the fluid level in the bodyb, either the blood, sugar, etc., the osmoreceptors, a special group of cells within the hypothalamus part of the brain, will detect this.
Thereafter, a signal is sent to the posterior pituitary gland to release the antidiuretic hormones (ADH), whose job is to maintain the fluid level by causing an increase in water reabsorption into the body through the expansion of the epithelial cells of the kidney.
Answer:
Genotype: 100% or 4/4 of the progeny will be heterozygous for the trait, Yy.
Explanation:
<u>Available data:</u>
- Two plants differ in the seed color they produce.
- One plant produces green seeds, the other produces yellow seeds.
- Yellow is the dominant phenotype, over green which is the recessive phenotype
- The parental plants are true-breeding
Let us say that the allele Y expresses yellow color and is dominant over the allele y which expresses the green color and in the recessive one.
Cross: a green-seeded plant with a yellow-seeded plant
Parental) YY x yy
Phenotype) Yellow seeds Green seeds
Gametes) Y Y y y
Punnet square) Y Y
y Yy Yy
y Yy Yy
F1) Phenotype: 100% of the progeny will be yellow-seeded
Genotype: 100% or 4/4 of the progeny will be heterozygous for the trait
