Answer:
a. This is actually a case of frequency-dependent selection. With too many cheaters in a population, the fruiting body's stalk is not built well, and all individuals have lower fitness.
Explanation:
Frequency dependent selection is a process in evolution whereby the
a gene, genotype or phenotype varies depend on the percentage of that gene, genotype or phenotype that is present in the population.
There are two types of frequency dependent selection:
a. Positive frequency dependent selection.
b. Negative frequency dependent selection.
Answer:
1. Use a Rain Barrel. There are several options when it comes to water catchment systems, so if you don't love the look of rain barrels, there are other systems.
2. Plant Trees or Shrubs. A great choice for any landscape, trees and shrubbery serve several purposes.
The right answer is the size.
Crystallization is the operation that consists, of a solution (solvent + solute) or a molten solid, to form a crystallized solid. The solute crystallizes in general in a predefined geometrical form (cubic, face-centered cubic, etc.), including or not solvent molecules (eg pure NA2SO4 or [Na2SO4, 10H2O]). The form or chemical formula of the crystals may depend on the crystallization temperature.
There are two ways of crystallization: The dry way and the wet way (in solution)
In crystallization in solution: the solute is initially in the liquid phase in a solvent. It is crystallized (solidification ordered according to a regular structure) within the solution either by solvent evaporation, or by cooling the solution, or both.
<span>Answer: Bone marrow stem cells have been shown to generate cartilage, bone, and muscle when injected directly into the injured site
