A punnet square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. The diagram is used by biologist to determine the probability of an offspring having particular genotype. Base on that the possible answer would be that the<span> two parents should have genotype a of something like XXi x XY where Xi is the allele for red eye colour</span>
Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane<span>. Carbon dioxide, </span>the<span> byproduct of </span>cell<span>respiration, is small enough to readily diffuse out of a </span>cell<span>. Small uncharged lipid molecules can </span>pass through the<span> lipid innards of </span>the membrane<span>.</span>
Answer:
c. A single enzyme typically reacts with many different substrates.
Explanation:
Enzymes are proteins that have catalytic activity and they are specific. This means that a single enzyme has only one specific substrate. They act as a "lock and key" complex, so one substrate activates to one enzyme.
Also, enzymes accelerate the rate of a reaction by lowering its activation energy. Finally, they can act in an aqueous environment, so the answer is c.
Symaptric speciation is the formation of new species in populations that live in the same geographic area, while allopatric speciation occurs when the population is separated by a geographcial area. So, according to this: The difference between the sympatric speciation and the allopatric speciation is that sympatric speciation involves a behavioral barrier, while allopatric speciation involves a physical barrier.
I would say it would respond w/ it hurting and your gasping for air because when you run for a long periods of time u get a pain that hurt from running so much and because your dehydrated and ran out of breath
