In the wild, various sperm and egg cells must navigate a complex environment to complete fertilization. There are mechanisms in

g100num [7]

Answer:

pre-zygotic reproductive isolation

Explanation:

The molecules regulate the pre-zygotic reproductive isolation mechanism.

Reproductive isolation generally refers to the variety of biological processes that sustain the formation of new species of biological organisms.

Some of these processes act to prevent fertilization or the formation of zygotes between organisms that are not of the same species (pre-zygotic mechanisms) while others ensure that the product of fertilization is invalid in case the former fails (post-zygotic mechanisms).

Some pre-zygotic mechanisms ensure that there exists no form of mating among organisms that are not of the same species due to incompatible reproductive organs, but where this fails, another pre-zygotic mechanism will act so that that the mating will not lead to fertilization and there will not be formation of zygotes.

The prevention of fertilization between organisms with compatible reproductive organs but of different species is carried out by molecules. These molecules ensure that there are locks and keys in place to prevent the fertilization of the egg by the sperm.

What is the correct order of the missing ecological levels of organization? Organism -> _______ -> ______ -> ______ -&g

Ksivusya [100]

(An individual can also be defined as an Organism)

Answer:

Population, Community, Ecosystem, Biome

Explanation:

A population is a group of individuals within the same species, within the same area, and that are capable of reproducing with one another.

A community is a defined as the populations of two or more species within the same geographical area and within the same time period.

An ecosystem is a community along with its abiotic (non-living) components, such as the water and air.

A biome is a large ecological area with similar climatic conditions. A biome can have multiple ecosystems within it.

The biosphere includes all living organisms along with the spheres they interact with (lithosphere, hydrosphere, etc.).

Therefore the correct answer is Population, Community, Ecosystem, Biome, Biosphere
