Answer:
Tan fur helps the mice protect themselves from predators
Explanation:
The entrenchment of this phenotype in the population is powered by natural selection pressures. The mice with fur color that enable them to camouflage with their environment are predated less than mice with other fur colors. These tan mice are therefore more likely to survive and pass their genes to the next generation. Through successive generations, the allelic frequency for the tan fur color increases until it is the dominant allele in the population.
Answer:
Wind and moist air is drawn by the prevailing winds towards the top of the mountains, where it condenses and precipitates before it crosses the top. The air, without much moisture left, advances across the mountains creating a drier side called the "rain shadow".
The windward side of the mountain is the side of the mountain that the wind blows into. This side is where all the rain tends to be because of the air cools as it rises, making clouds. The opposite side is called the leeward side. This is where the air sinks, leaving the side much more warm and dry.
Explanation:
In a food chain, only 10% of energy is transferred from one trophic level to another trophic level. If the energy produced at the producer level is 1000 J, then the energy available at the primary consumer level will be 100 J and energy available at the secondary consumer level will be 10 J.
Answer:
A photosynthetic cell within a plant leaf produces chemical energy, stored within glucose molecules.
Explanation:
The energy captured from sunlight by Photosystems in chlorophyll is used to split a water molecule and reduce carbon dioxide to carbohydrates. This energy from sunlight is therefore stored in the chemical bonds of the glucose molecules. It is thereafter harnessed during cellular respiration when the chemical bonds of glucose are broken and the energy transferred to make ATP molecules.
<span>We have two surfaces of nerve cell the outer and inner surface
- resting : when the outer layer ion charges more positively than the inner layer - depolarization : we have the counter part of this state
- repolarization : return to the polarization
- hyperpolarization : the inner negative ion charges will be more negative even more than the resting potential
I hope that this is the answer that you were looking for and it has helped you.
