Answer:
The orchids derive nutrients from the association at very young stages of its life cycle while the fungi obtain water and organic matter
Explanation:
As stated in this question, fungi species belonging to the phylum Basidiomycota form mycorrhizal associations with a flowering plant called orchids. This relationship is a mutualistic one because both participants benefit from the relationship.
In this association, the young orchid plant relies on the mycorrhizal fungi's metabolism to get nutrients needed for its development in form of carbohydrates while the fungi in return gets water (from the roots of the plant) and organic matter.
Groundwater is stored beneath the earth's surface in soil pore spaces and cracks and openings in rock formations.
Answer:
C.) Disruptive selection
Explanation:
Disruptive selection is also called as diversifying selection. Here, two or more extreme phenotypes are preferred over the intermediate phenotype. Since more than one phenotype is preferred here, the genetic diversity of the population increases over generations.
For example, in lobsters alpha males are able to successfully mate by using force. Smaller males can also sneak in alpha males's territory and successfully mate. Hence, both alpha males and small males will be preferred over medium sized males in lobsters increasing the overall genetic diversity of population.
Two spotted leopards produce a litter of four cubs. Three of the cubs are spotted and one is solid black. The black coat is<u> Recessive Trait</u>
Explanation:
A recessive trait is a trait that have been expressed when an organism has two recessive alleles or two forms of a gene.
Traits are called the physical/non-physical characteristics of a organisms that can or cannot be observed.
Physical characteristics like hair, eye color can be observed while other characteristics like the shape of blood cells cannot be observed.
It is important to note that if the trait is dominant, one of the parents will have the trait. Dominant traits does not skip a generation. In case the trait is recessive, neither of the parent will have the trait .Recessive trait can skip a generation
So we can say that in the case mentioned in the question
Two spotted leopards produce a litter of four cubs. Three of the cubs are spotted and one is solid black. The black coat is<u> Recessive Trait</u>
