Population B: L, E
Population C: G, J
Explanation:
Biologists studying disease susceptibility in mice used genetic techniques to look for gene flow in 12 wild populations of mice. The populations (designated A through L) were located along a 210-km transect line.
Answer:
Genotype - AaMm
Phenotype - Heterozygous purple stem and fruit with two locules
Explanation:
Given
Trait 1 - Recessive allele for green color stem is represented by a
and dominant allele for purple color stem is represented by A
Trait 2 - Production of two locules in the tomato fruit is a dominant trait and is represented by "M" and production of multiple locules in the tomato fruit is a recessive trait and is represented by "m"
F1 cross is carried between tomato plant with purple stem and fruit with two locules (AAMM) and a tomato plant that have fruit with multiple locules and a green stem (aamm)
The following offspring will be produced
AM AM AM AM
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
am AaMm AaMm AaMm AaMm
Genotype - AaMm
Phenotype - Heterozygous purple stem and fruit with two locules
The coronary artery supplies blood to the heart. if there are blockages, you will have a heart attack, since this artery supplies oxygen rich blood to the heart. Without it, the heart can die
The right answer is The first image (the left one).
An atrium is an upper cavity of the heart, delimited by a thin wall, receiving blood from the bloodstream. There are two in the human heart, they allow the passage of blood from the veins (cellars and lungs) to the ventricles (right and left).
In its upper part (near the entrance of the superior vena cava) is located the sinus node, microscopic structure from which the electrical impulse which ensures the contraction of the heart (especially atrium) ...
The depolarization of the action potential is conducted step by step in the cells of the right and left atria, accompanied by a contraction of the muscle fibers.
