A would have it.
A is hetrozygous person. Since it is dominant, you only need 1 "H" to recieve the gene. Since B has two "h", it would not contain the disease.
Answer:
Because the water molecules are small, many of them can surround one molecule of the solute and form hydrogen bonds.
Explanation: Because of the attraction, the water molecules can pull the solute molecules apart so that the solute dissolves in the water.
Answer: First, the bacteria will adjust and then it will divide.
Explanation:
Once the bacterial species is put into the cultural medium, there the bacteria present in the medium needs to acclimatize in the medium and then start growing.
There is a lag phase before the log phase because first the bacteria will adjust into the medium and then start dividing.
As we know that the growing medium contains amino acids, growth factors, enzymes and many more things which first needs to be utilized by the bacteria and then it will start dividing.

Answer:
"As a molecule moves through the plasma membrane it passes through <em>a hydrophilic layer of phospholipid heads then a hydrophobic layer of phospholipid tails and then another hydrophilic layer of phospholipid heads".</em>
Explanation:
Biological membranes are formed by two lipidic layers, proteins, and glucans.
Lipids characterize for being amphipathic molecules, which means that they have both a hydrophilic portion and a hydrophobic portion at the same time. These molecules have a lipidic head that corresponds to a negatively charged phosphate group, which is the polar and hydrophilic portion. They also have two lipidic tails that correspond to the hydrocarbon chains -the apolar and hydrophobic portion- of the fatty acids that esterify glycerol.
Membrane lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane.
Through this lipidic bilayer, some molecules can move from one side of the cell to the other, which happens because of concentration differences. When this occurs, molecules must pass through the hydrophilic layer of phospholipid heads then through the hydrophobic layer of phospholipid tails and then again through another hydrophilic layer of phospholipid heads.
