Answer:
Bb ll for the black short-legged horse
bb Ll for the brown long-legged horse
bb ll for the offspring
Explanation:
In order for the offspring to have the two recessive traits, the parents must have been carrying the recessive genes on at least 1 allele. The first horse is black, but it must have a little b for the offspring to gain a little b from it. The second horse and the offspring are brown, so they must both have two little b's. The same goes for the length of the legs. The first horse and offspring must have two little l's because they have short legs and the second horse must have 1 little l in order for the offspring to inherit 1.
Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs.
Explanation:
5. The larger the cell, the harder it is to get nutrients and gases to move in and out of the cell.
6.Small
7.Small, as they have a higher surface area to volume ratio which allows them to rely on oxygen and material diffusing into the cell to survive.
8.Prokaryotic cells have internal folding of cell membrane which is responsible for certain functions like respiration.
And in Eukaryotic are compartmentalised which is a method to increase surface area.
