Answer:
A homozygous dominant trait will have both the dominant alleles of a gene for a trait. For example, the AA genotype of the 80 brown gerbils.
A heterozygous trait will have one dominant and one recessive allele for the particular gene. For example, the Aa genotype of the 64 brown gerbils.
A recessive trait will be the trait in which there is no dominant allele for the gene. The suppressed trait only occurs when both the alleles of the gene are recessive. For example, the aa genotype of the black gerbils.
The completed table is shown in the attachment.
This is true.
Facilitated diffusion is a process by which molecules are transported across the plasma membrane with the help of membrane proteins.
It is a type of passive transport in which no energy from the cell is required for the process because a concentration gradient exists that allows movement of particles without expending cellular energy.
Materials diffuse across the cell membrane with the help of membrane proteins some of which are known as carrier proteins.
Membrane proteins are proteins that are attached to, or associated with the membrane of a cell or an organelle.
Low levels of water in the blood, causes more release of anti-diuretic hormone (ADH) into the blood. It causes increases in the retention of water in the kidneys, and thus, blood volume is increased. This may be caused by dehydration and leads to less volume of urine. It is released by the hypothalamus and stored in the posterior pituitary.
