If Malaria is contracted, where within the body does it reproduce before attacking the red blood cells
Answer:
the liver
Explanation:
With some species of malaria, such as Plasmodium vivax and Plasmodium ovale, the parasite can lie dormant in the liver. It can therefore take up to a year for symptoms to develop (see life cycle above). Once inside the body, the malaria parasites grow and multiply inside the red blood cells.

explain the roles of mRNA and tRNA in protein synthesis
Answer:
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein synthesis

Which of the following is an accurate description of a positive feedback loop? SC.912.E.7.7
A.
It is uncommon in nature and it makes systems stable.
B.
It is common in nature and it doesn’t change the stability of systems
C.
It is uncommon in nature and is usually caused by humans
D.
It is common in nature and it makes systems stable
Regulatory functions such as feedback loops are very common in nature and happen thousands of times every day within our bodies alone.
A feedback loop is one of the methods by which biological organisms regulate functions. Feedback loops are a self-regulatory means through which the output of a system is then used as the input. Feedback loops can be of two types:
Positive FeedbackNegative FeedbackA positive feedback loop is one in which the system is stimulated to increase the production of a product. For example, the low levels of an enzyme in the blood will cause the body to produce more of that enzyme in a positive feedback loop. A negative feedback loop is just the opposite, in which high levels will cause a decrease in production.
Feedback loops are a vital part of maintaining homeostasis and for the survival of all organisms. Therefore, we can conclude that option D is correct in stating that feedback loops are common in nature and make the system stable.
