it's (+/-) 90 degrees. in total it's 180 but the equator is at zero and the two hemispheres have 90 each
Answer:
plants animals and cosmic rays
If a side of the cell is Hypertonic it means that that side has a greater concentration of solute, meaning eater will want to move to that side.
Therefore a hypertonic solution has more solute outside than inside the cell. So water will leave the cell.
Answer:
The biologist is analyzing deleterious and beneficial mutations.
Explanation:
In general, mutations are deleterious genetic changes that negatively affect the fitness of the individual in a particular environment. However, there are occasions where a mutation may be beneficial. These mutations are beneficial because they confer an adaptive advantage (for example, by generating new versions of proteins) that enable the individual to adapt to their environment, thereby increasing their chances to survive and reproduce. If a beneficial mutation is new it will be distributed disproportionately among populations, thereby it is possible to determine the novelty by determining the frequency of the mutation among populations. Ideally, this new mutation should have a value of 0 in the non-target populations (i.e., this mutation does not exist in these populations), and a very low value in the target population (i.e., this mutation appeared very recently). Since mutations provide the raw material for natural selection, it is expected that a new mutation increases their frequency in the population, but if this genetic change is deleterious in a particular environment, natural selection will decrease their frequency. Deleterious mutations are accumulated in populations with small sizes faster than it can eliminate them, thereby the identification of these genetic changes can result useful for the design of conservation strategies in endangered species.
The answer is 8,000 calories. This is because, in the transfer of energy from one trophic level to another, only 10% becomes available to be converted to biomass. The other 90% of lost into the environment as heat. This is why the energy pyramid tapers a you go up the pyramid.
