exchange of gases in the human breathing system takes place in the?​

Answers

Answer 1
Answer

alveoli

Explanation

During gas exchange oxygen moves from the lungs to the bloodstream. ... This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Answer 2
Required Answer :-

The exchange of gases takes place in the alveoli.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Additional information :-

Alveoli are microscopic air sacs.

They are the primary sites of exchange of gases. Gas exchange also occurs in lungs and tissues by diffusion.

Atmospheric air contains little CO2, but blood flowing in pulmonary capillaries has a higher concentration of CO2.

CO2 diffuses from higher concentration in blood across walls of alveolar capillaries to lower concentration in air in alveoli.

Blood coming into pulmonary capillaries is oxygen poor and alveolar air is oxygen rich.

Oxygen diffuses from higher concentration in alveoli across walls of alveolar capillaries to lower concentration in blood.

The sequence of events which produces another generation of organisms is called as the Life cycle.

What is Life cycle?

Life cycle is defined as the series of changes which members of a species undergo from the beginning of a given developmental stage to the beginning of the same developmental stage in a subsequent generation.

In many simple organisms including bacteria and various protists, the life cycle is completed within a single generation where an organism begins by fragmentation of an existing individual and the new organism grows to maturity which then splits into two new individuals, so the life cycle is complete.

Thus, the sequence of events which produces another generation of organisms is called as the Life cycle.

What are abiotic factors in an ecosystem?

An ecosystem is a place where biotic factors (that have a life) and abiotic factors (that have no life) converge, for the balance of the ecosystem both are necessary.

For example, in an ecosystem, animals and plants are the biotic factors, and among them, there are relationships such as animals that feed on other animals or others that feed on plants. But this life would not be possible if there were no factors such as water, sun, soil, oxygen, among others. So, the correct answer is C.

Thus, option "B and F" is correct.

How does a forest fire impact a population of birds that nest in the trees.

Answers

Answer:

If a forest fire occurs it will impact a population of birds that nest in those trees because their habitat will be burnt down. This will provoke the birds to find a new habitat which can be hard if the entire forest is burnt down. Additionally resources such as food will be burned down as well.

Assuming birds escape a fire, smoke might still affect their health in ways that aren’t very well understood. Scientists have found that smoke can damage lung tissue and leave the animals susceptible to potentially lethal respiratory infections.
