<u>Answer:</u>
Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs). ROSs can damage mitochondria. Damaged mitochondria generate more ROSs than healthy mitochondria. This is an example of a positive feedback mechanism
The reactive oxygen species that are given out by the mitochondria during cellular respiration are the major cause of aging. Though this has a lot of negative effects but this also has a small amount of positive effects such as the start of angiogenesis or cell proliferation.
Answer: B. Red blood cells released by immune cells cause increased blood flow to the infection site; this increased blood flow brings other red blood cells to the area more quickly.
Hey There,
The answer to your question is:

Answer;
- Proteins, nucleotides;
Amino acids are needed to build proteins just as nucleotides are needed to create DNA.
Explanation;
-Amino acids bond together to make long chains. Those long chains of amino acids are also called proteins. Protein plays a crucial role in almost all biological processes and amino acids are the building blocks of it. A large proportion of our cells, muscles and tissue is made up of amino acids, meaning they carry out many important bodily functions, such as giving cells their structure.
-Nucleotides are the building blocks of nucleic acids; they are composed of three subunit molecules: a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group.
That body parts are called "Homologous Organs" which are similar in origin & structure.
Hope this helps!
