Through my research I found questions similar to this with answer choices:
A) medicinal material excreted by macrophages
B) the death of macrophages
C) pathogens trying to infect the area
D) blood cells losing their hemoglobin
The best answer among the following choices would be the second option aka B) The death of Macrophages because cutting your knee is cutting your skin since something sharp went through the layers it basically killed things in order to get to you, to make you feel the pain, so as a result of the cut, it killed the macrophages, which are like your security system for your immune system that protects you, but the cut broke through and harmed the skin.
Answer:
of diffusion
Explanation:
Molecules move down a concentration gradient without the need to use energy. This means they move from a high concentration to a low concentration. This occurs across a semi-permeable membrane, like the cell membrane, by simple diffusion.
Answer:
Option-1 and 4
Explanation:
Fatty acids can be distinguished into two types: saturated and unsaturated fatty acids.
The saturated fatty acids are the fats that do not contain any double bond as a result of which they are tightly packed and are found in solid-state whereas unsaturated fatty acids are the acids that contain double bond in their structure and are found in liquid form.
The cold-tolerant species show an adaptation to survive in cold species by modifying their cell membrane composition that is they increase unsaturated fatty acids which help in maintaining the fluidity of the cell membrane.
Thus, in the given question option-1 and 4 show, this adaptation and are true options.
DNA polymerase is a type of enzyme that is responsible for forming new copies of DNA, in the form of nucleic acid molecules. Polymers are Nucleic Acid, which are large molecules made up of smaller, repeating units that are chemically connected to one another.
Answer:
Dendrite to axon to cell body
Explanation:
Rabies virus is transmitted to human body when an infedted animal bites into human muscles. It enters into neurons via dendrites and travels via axon to cell body.
