Which compositional layer is divided between three mechanical layers?

Answers

Answer 1

Answer:

The compositional layer that is divided between three mechanical layers is the Earth's crust. The Earth's crust is the outermost layer of the Earth's solid surface and is composed of several distinct mechanical layers, namely the lithosphere, the asthenosphere, and the mesosphere.

1. Lithosphere: The lithosphere is the rigid, outermost mechanical layer of the Earth's crust. It is composed of the uppermost part of the mantle and the crust. The lithosphere is broken into tectonic plates that float and move on the semi-fluid asthenosphere below.

2. Asthenosphere: The asthenosphere is a semi-fluid, plastic-like layer beneath the lithosphere. It is composed of hot, weak, and partially molten rock materials. The asthenosphere allows the tectonic plates of the lithosphere to move and interact with each other.

3. Mesosphere: The mesosphere, also known as the lower mantle, is the deepest mechanical layer beneath the asthenosphere. It is a more rigid and solid layer compared to the asthenosphere. The mesosphere extends from the bottom of the asthenosphere to the Earth's outer core.

Together, these three mechanical layers form the Earth's crust, which is the outermost compositional layer of the Earth.

Calcium levels in the body are maintained by hormones. If the blood calcium level rises above a set point, calcitonin is secreted by the thyroid gland and sets into motion responses to lower the blood calcium back to the set point. If the blood calcium level falls below a set point, the parathyroid gland secretes parathyroid hormone that sets into motion responses to raise the blood calcium.

Answers

Answer: Primary growth.

Explanation:

Most of the primary growth occurs at the tips, apices of the stem and roots. It results in the growth of plant in height.

This is caused as a result of rapidly-dividing cells that lies in the apical meristem at the root and shoot tip of the plant.

This growth enables the plant to absorb water from the roots and sunlight at the shoots in order to grow.

Why is it that two species cannot occupy the same niche for an extended period of time?

Answers

A niche is a specie's function in its habitat or its level on the food chain, so two species competing at the same level for the same food and habitat eventually one species will have to migrate or starve due to lack of food.

Answer:

In terms of ecology a niche can be defined as role or function an organisms play within the ecosystem. A niche represent the interaction of an organism with the living and non living components of the ecosystem. It is represented by predator-prey relationships, parasitic and mutualistic properties and other functions. The two species cannot occupy the same niche for an extended period of time, this can be explained by competitive exclusion principle. According to this principle, no two species can have the same ecological niche. The two or more species competing for the same resource in an ecosystem the one species having more favorable adaptations will be able to thrive resources better than others. Therefore, this will result in the decrease in abundance, migration and extinction of weak and less competitive species.

A plant with the dominant trait, wrinkled seeds, is crossed with a plant that has non-wrinkled seeds. All of the offspring are all wrinkled-seeded. What is the likelihood that the gametes of the wrinkled-seeded parent plant contain one non-wrinkled allele?

Answers

The answer is 0 percent.

If we represent dominant trait (wrinkled seeds) with A and recessive trait (non-wrinkled seeds) with a, then genotypes are AA (dominant homozygous), Aa (heterozygous), and aa (recessive homozygous). The phenotype of wrinkled seed is determined by genotypes either Aa or AA. Since the cross of a plant with wrinkled seed with a plant with non-wrinkled sees gives only wrinkled-seeded offspring, the plant with wrinkled seeds must be dominant heterozygous.
Let's look at both examples.
If wrinked-seeded parent contains one non-wrinkled allele, it must be heterozygous (Aa):

Parents: Aa x aa
Offspring: Aa Aa aa aa

So, the 50% of offspring has wrinkled seeds and 50% has non-wrinkled seeds.

If the wrinkled-seeded parent does not contain any non-wrinkled allele:
Parents: AA x aa
Offspring: Aa Aa Aa Aa

Thus, all of the offspring are heterozygous and all of them have wrinkled seeds.
