Which layer of Earth has the highest density and temperature?

Biology
1 answer:
MrRissso [65]3 years ago
5 0
<span>Because of the difference in materials and the compression of gravity at depth, the inner core is the highest density. The lowest is the crust which is basically floating on the mantle. While no one has drilled that far, the basic assumption from magnetism and pieces of other planets delivered as meteors is that the inner material is iron, nickel and other heavy magnetic elements along with heavy radioactive elements.

The final answer to your question is C. core.

I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. A scheme of blood circulation
Soloha48 [4]

Answer:

The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.

Explanation:

In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.

Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.

Explain the 6 steps of how Darwin theorized how the finches formed new species:
Scilla [17]
Overproduction
Most species produce more offspring than can survive.

Competition
Since living space and food are limited, organisms must compete for the necessities.

Variation
Differences between individuals in a population.

Adaptations
Any kind of inherited trait that improves an organism's chances of survival.

Natural selection
The environment selects organisms with optimal traits to be the parents of the next generation.

Speciation
Over many generations, favorable adaptations accumulate and may result in a new species.
