The reason is to help in seed dispersal. Seed dispersal is the movement or transport of seeds away from the parent plant. Due to the fact that plants have very limited mobility they have to rely upon variety of dispersal; vectors to transport their seeds, including both abiotic and biotic factors. Seed dispersal is important because if seed are not dispersed, many germinating seedlings will grow very close to the parent plant which would result to competition between every one of the seedlings as well as the parent. The competition for essential growth factors such as light, space, water and nutrients.
<span>The organic chemicals that help
cell membranes to conserve internal fluids are the phospholipids. They are
composed of fatty acid, glycerol, phosphate group and a polar molecule. The phosphate
group and polar head region of the phospholipids is attracted to water while
the fatty acid is repelled by water. They are a major component of the cell
membrane in which it encloses the organelles of the cell. It also limits what
enters and exits the cell because of its two heads.</span>
Answer:
earthworms and phytoplankton I think
Explanation:
earthworms are decomposers so thats their job and I'm not sure about the other one I'm kinda guessing but I know it's none of the others so it has to be that one
According to Gloger's rule, endothermic creatures should have darker hues in hot, rainy areas. The so-called complex Gloger's rule also states that animals should be more rufous in warm, dry regions.
Explains the connection between animal color variation and large-scale climate gradients. Bernhard Rensch gave it that name in 1929 to honor Constantin W.L. Gloger, who was one of the first to write about relationships between animal pigmentation and temperature in 1833.
Gloger's rule, as it is known now, states that mammals and birds should be darker in warm, humid settings than in colder, dry ones.
Gloger's rule-related color variation is mostly caused by variations in melanin pigmentation, according to this quick reference.
The most prevalent pigment in birds and mammals, melanin's are of two primary types: pheomelanin's, which produce brown, buff, and rufous colors, and eumelanin's, which produce black and different shades of grey. Both generate intermediate hues when combined.

Answer:
Explanation:
Hardy Weinberg law is represented by the equation below
p² + 2pq + q² and states that the frequency of alleles and genotypes will remain constant in the absence of evolutionary disturbances such mutation, natural selection, migration and the population is large and mating is random.
where p² represent the frequency of homozygous dominant geotypes and 2pq represent the frequency of heterozygous genotypes and q² represent the frequency of the homozygous genotypes
p is the frequency of the dominant alleles and q is the frequency of the recessive alleles.
given
q² = 25% = 0.25
q = √0.25 = 0.5
