Under a microscope, gram-positive bacteria (when dyed with the gram stain) appear in purple-colored structures due to the peptidoglycan cell wall.
<h3>What are gram-positive bacteria?</h3>
Gram-positive bacteria are microorganisms (bacteria) that may be colored with crystal violet stain due to the presence of a peptidoglycan-based cell wall.
In conclusion, under a microscope, gram-positive bacteria (when dyed with the gram stain) appear purple-colored structures due to the peptidoglycan cell wall.

I had just learned this! The answer is D.
Producers, which are the base of the food chain for ecosystems are essential and do not require oxygen to cycle energy and matter, as they create oxygen through photosynthesis. Plants are producers that use this process to capture light energy and use it to convert carbon dioxide and water into an organic substance known as glucose.
The answer is punctuated equilibrium. This is a theory in evolutionary biology that says the evolution of different species proceeds in a characteristic way of relative stability for very long periods interspersed with shorter periods. During this period new species emerge as others become extinct.
Answer: Antibodies are proteins that are found in the body on the surface of red blood cells and in the blood plasma ,they are very sensitive to foreign bodies and bad viruses and bacteria,when they notice the presence of anything that poses harm or a threat to the body system,they track it down and fight/destroy it.
Antibodies also play crucial role in hemostasis(stoppage of bleeding) in the sense that when the body is wounded or when someone gets a cut antibodies that are found in the plasma and some substances found in the platelets are released to play a role in sending signal to the blood clotting factors in the blood to be released to arrest the bleeding and prevent the person from bleeding out their entire blood.
