The correct answer is option A.
The immune system safeguards the body against the probable harmful materials by reacting and determining the antigens. Antigens are the components situated on the surface of viruses, cells, bacteria, or fungi. The immune system destructs and determines, or attempts to destroy the components, which comprise antigens.
Nonspecific or innate immunity is the defense system with which an individual is born. It safeguards the person against all the antigens. Innate immunity includes barriers, which keep the harmful substances from getting inside the body. These barriers make the first line of defense in the immune reaction.
Cell membrane of a cell is responsible for the substances
that goes in and out of the cell’s cytoplasm and organelles. It is transports
different materials externally to internally and vice-verse. Hence the cell
membrane is like
<span><span>1. </span>The wall,
window and door of a house.</span>
<span><span>2. </span>The
security guard of a certain bank</span>
<span><span>3. </span>Or the
military sector of a country.</span>
Like these three real-life examples, they regulate and
control the flow of certain entities from outside to inside and vice-versa.
Answer:
C. Oxygen supply
Explanation:
Autotrophs make their own food with carbon dioxide and create oxygen as a byproduct. Heterotrophs need oxygen to create energy and create carbon dioxide as a byproduct. Therefore, if there are no autotrophs, the carbon dioxide in the air won’t be able to be used to turn to oxygen, which heterotrophs need. The heterotrophs will use up all of the oxygen in the air, leaving lots of carbon dioxide behind. This is why we need plants and trees! Thus, the answer is C.
I hope this helps! :)
