The answer is <span>A. The Y chromosome doesn't experience crossing-over.

</span>The crossover of chromosomes is the exchange of genetic material between homologous chromosomes. In males, X and Y chromosomes pairs but they cannot exchange genetic material except at the ends of the chromosomes called pseudoautosomal regions. So, greatly, the Y chromosome <span> doesn't experience crossing-over.
</span>
Through the process of elimination:
B. A mother gives X chromosome and a father gives Y chromosome to the son.
C. The mitochondria cannot be passed in the nucleus of a cell since it is another organelle.
D. It is thought that mitochondria is passed only from mother to her offspring, so they cannot vary greatly.

How do sulfur and phosphorus move from the biotic to the abiotic pools during their cycles? A) Primary consumers eat producers.

worty [1.4K]

Answer:D) Decomposers break down the remains of producers and consumers

Explanation:A biotic pool is a tidal pool with diverse and changing habitats of living factors. We can say they are important mini ecosystems within the larger ecosystem.

The abiotic pool involves the elemental phases of nature,the non living parts of the ecosystem. Decomposition (break down) of elements/organic compounds is the characteristic bridge between both pools into what is known as nutrients.

This tell us that the ultimate dead part of producers and consumers are used up in this process.

Some of the nutrients released in the biogeochemical cyclic process includes sulfur and phosphorus and they move through the ecosystem.

Note: The biogeochemical cycle is a pathway of movement for chemical elements.

The chemical elements in nature moves through both biotic and abiotic components via abiotic and biotic interaction in the ecosystem

Few abiotic factors includes rocks, air, water, and chemicals while biotic factors includes living organisms activities.

All living and non living elements of nature play vital roles in the great biogeochemical cycle.

Drag each tile to the correct location. Determine whether each sentence describes oceanic crust, continental crust, or both. It

neonofarm [45]

Given what we know, the three sentences in this question all describe the properties of oceanic crust.

<h3>What is the oceanic crust?</h3>

The oceanic crust is the outer layer of the earth, located at the bottom of the oceans.
It contains three layers, ordered by number.
During subduction, this remains the topmost crust.
It is formed by the solidification of magma.
The oceanic crust is known to be very dense.

Therefore, we can confirm that the sentences in the question describe oceanic crust given that this is the topmost crust during subduction, formed by the solidifying of magma, making it a much denser rock than the other forms of crust.

predict if the sensory nerves in a persons foot are nonfunctional, would the person feel pain if the foot was severely burned

irina1246 [14]

Nerves are cells that can detect any type of pressure, movement, or anything of that nature. If we didn't have nerves, we couldn't feel pain. If the nerves in a foot are damaged, you wouldn't feel the pain of it being burned.

The process by which ions join to reform the solid is called dissolution

mestny [16]

I believe the process by which ions join to reform the solid is called precipitation. It is a process in which ions leave a solution and regenerate an ionic solid. For example; Ag+(aq) + Cl-(aq) = AgCl (s). Dissolution on the other hand is the process in which an ionic solid dissolves in a polar liquid; it is the opposite of precipitation.
