Respiration is the chemical reaction that break down nutrient molecules in living cells to release energy .
in humans and other living organisms except plants, our cells need energy ATP for muscle contraction and for cell division to repair damaged tissues and growth ,also for active transport which involves movement of molecules across a cell membrane against a concentration gradient.
Answer:
It wouldn't be able to pump oxygen to your body
Explanation:
One side goes to the lungs to collect oxygen and the other side pumps the oxygen to your body. If there was no chamber the blood would not be able to flow to its proper area and you would die
Answer:
B
Explanation:
Chloroplasts have two membranes: <u>external and internal membrane.</u> These membranes contain 60% of lipids and 40% of proteins, just like the typical cell membranes. The <u>inner or internal membrane</u> is virtually non-permeable to any substances but it has transport proteins, on the other hand, the <u>outer or external membrane</u> is permeable to most of the small molecules
Answer:
It spreads by conjugative plasmid.
Explanation:
Bacterial population spreads their antibiotic resistance by conjugative plasmids, a circular DNA with locus for partitioning and origin of replication. Conjugative plasmids exist naturally in bacteria. Normally they multiplyand live inside the cells, using their synthetic machinery, but can also transfer its genes to neighbouring cells. It is this characteristic that causes rapid antibiotic resistance in bacterial population even if those bacterial species are not related to each other.
