It is useful for the walls of capillaries to consist of a single layer of thin, flattened cells in order to easily diffuse oxygen and nutrients easily from the blood and into the capillaries. Not only that, but this also makes it more efficient for carbon dioxide and other waste molecules to diffuse from the capillaries and into the blood. If capillaries were thicker than a cell, then it would be more difficult for materials to diffuse through the thick layer of cells.
The phenotype of the F1 generation offsprings will be black. They will be heterozygous in nature.
<h3><u>Explanation:</u></h3>
The genes for the fur colour in horses are completely dominant and the dominant colour is black and is represented by B. The recessive colour is chestnut and is represented by t.
The genotype of the homozygous black horse is BB. and the genotype of the homozygous chestnut coloured parent is tt.
The gametes from the black parent =B.
The gametes from the chestnut parent = t.
So the genotype of the F1 offspring = Bt.
It is a heterozygous black horse because the black gene is completely dominant over chestnut gene.
Tt - because heterozygous means [different] so it’s 2 different letters
Answer:
The amount of light that a plant has determines how much the plant grows, plants need sunlight for photosynthesis, and photosynthesis is how they make food so if a plant has little to no sun it won't grow well.
4 earth months i think that is not totally correct
