When tissues are harmed by bacteria, trauma, heat, or any other cause, an inflammatory reaction occurs.
<h3>What happen when a honey bee stings?</h3>
When a honey bee stings or a disease infects damaged cells, chemicals are released. chemicals are a group of substances that include prostaglandins, histamine, and bradykinin. These substances promote swelling by forcing blood vessels to leak fluid into the tissues.
During the inflammatory reaction, the following processes occurred:
Redness, swelling, and loss of function are all symptoms of heat.
Inflammation is the body's natural defense system. Damaged cells, irritants, and infections are recognized by the immune system, white blood cell kills the antigen and stimulates the other defense cell to act. this process is called a macrophage.

Answer:
Natural selection happens to...
A: Species
Answer:
a.genetic code in the nucleus- DNA
b. main component in a ribosome- rRNA
c. translated with introns removed- mRNA
d. attached to amino acids -tRNA
e. translated including introns- pre-mRNA
Explanation:
a. DNA- is a nucleic acid molecule that acts as a genetic material in the organisms. In eukaryotes, the DNA molecule is present in the nucleus of the cell
.
b. rRNA- is a molecule formed by the transcription but does not undergo translation and is directly involved in the formation of the ribosome structure which provides the site for the protein synthesis.
c. mRNA- is the RNA formed from the DNA by transcription which contains the message for the formation of the protein molecule. The mRNA is formed after the modification like splicing which removes the non-coding sequence.
d. tRNA-transfer RNA is involved in the translation of mRNA as it brings a specific amino acid to the peptide after it recognizes the codon.
e. pre-mRNA- is the mRNA molecule that has not undergone any modification and thus contains the non-coding sequence also.
Answer:
the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
