Which of the five stages of respiration takes place at the alveoli?

Answers

Answer:

External respiration is the exchange of gases with the external environment, and occurs in the alveoli of the lungs.

The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. External Respiration. Exchange of gases between air and blood at pulmonary capillaries (Alveoli) is the second stage. So it would be the 2nd stage

When the Earth's continental crust and ocean crust formed, they were different densities. Why did they differ in density and how did this affect their formation?

A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

B.) The continental crust was thicker and more dense. It sunk below sea level, separating land from water.

C.) The continental crust was thinner and less dense. It rose above sea level, separating land from water.

D.) The continental crust was thinner and more dense. It sunk below sea level, separating land from water.


I think it’s B, but I’m not completely sure. Help please!

Answers

Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

Explanation:

The Ocean crust is made out of rocks like basalt with a thickness of about four miles. The Continental crust on the other hand is made out of granite and other similar minerals and is between six and 47 miles in thickness which makes it thicker than the Oceanic crust.

With basalt being more dense than granite, the Oceanic crust sank and the Continental crust rose thereby separating land from water.

Answer:

Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

Which product is the result of light reactions in photosynthesis? O A. Water B. Glucose O c. Carbon dioxide OD. Oxygen ​

Answers

Answer:

D. Oxygen

Explanation:

Plants absorb carbon dioxide (CO2) and release oxygen for humans and animals to breathe in. Afterward, they'll release CO2 for plants to absorb, which forms a cycle.

Answer:

Oxygen

Explanation:

Both light dependent and light independent reactions in photosynthesis create glucose. But, only light dependent reactions convert carbon dioxide to oxygen.

Light independent: Carbon dioxide + water --> ATP and NADP(Energy/Glucose) and water

Light dependent: Carbon dioxide + water + light --> Glucose(ATP and NADP), water, and oxygen

Answer:

D) Evaporation, condensation, precipitation, runoff, collection

Please give me brainlyest

Explanation: The water cycle shows the continuous movement of water within the Earth and atmosphere. System that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Then I does runoff and creates a new water source or goes back to a water source.

Choose a statement that explains why competitive exclusion occurs between different species.
Limited resources are easily shared.
There are unlimited resources in the ecosystem.
Competition decreases the health of all animals.
One competitor is best at using a limited resource.

Answers

Limited resources are easily shared I believe

The statement "Limited resources are easily shared" is the one correct about the competitive exclusion between different species.

What is competitive exclusion?

It is the result of the competition in which a species is expelled by another more efficient species from a part of the available habitat.

Characteristics of the competitive exclusion

The competitive exclusion principle states that two species cannot occupy the same ecological niche in the same habitat.

If there are limited resources, eventually one species will exclude the other, given a certain period of time, through “competitive exclusion”.

Therefore, we can conclude that the competitive exclusion states that two species occupying the same niche cannot coexist in the long term since they would enter into competition for limited resources.

Does natural selection affect humans? How and why

Answers

Answer:

Yes it does affect humans.

Explanation:

Natural selection acts on the phenotype, but evolution is a change in the frequency of alleles in a population over time, a change in genotype. So natural selection acts on phenotype, but it is the connection to genotype that makes it the mechanism of evolution. Many traits vary among different members of a population of humans and animals, from body size to hair color, and those differences are often linked to differences in genes. Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. In scientific terms, these hazards are referred to as selection pressures. They put pressure on us to adapt in order to survive the environment we are in and reproduce. It is selection pressure that drives natural selection "survival of the fittest" and it is how we evolved into the species we are today.
