Answer & Explanation: Cholera as a disease is any of the several acute infectious diseases of humans and domestic animals caused by certain strains of the Vibrio cholerae bacterium.
a) It is unlikely to spread directly from one person to another. So the risk of becoming ill through casual contact is quite low. However, for those with weakened immunity, they could possible contract the disease on contact leading to infection.
b) Signs of infection is usually marked by severe gastrointestinal symptoms such as diarrhea, abdominal cramps, nausea, vomiting and dehydration
c) Some of the different ways the disease could be spread include ingestion of contaminated water. Bacteria present in the faeces of an infected person are usually the main source of contamination.
Answer:
Cell deterioration
Explanation:
Once the cells first come in contact, they immediately create a cell shield that is composed of weaker cells, while the rest continue their work, the problem with this, is that their is a lack of cells to do work and the weaker cells are slowly dying and creating holes for the harmful chemicals to enter, as the cells deteriorate they clot together and create a lump in a final attempt, and it ends up creating deadly weight in the lungs.
The answer is TRUE. Oxidative phosphorylation is usually a redox
reaction in which energy is released and used to form ATP from ADP and Pi. Oxygen
is the main electron acceptor. In eukaryotes, these redox reactions are
carried out by a series of protein complexes (electron transport chain) within
the inner membrane of the cell's mitochondria. NADH dehydrogenase or complex I is the
first protein in the electron transport chain. The reaction that is catalyzed
by this enzyme is the two electron oxidation of NADH by coenzyme Q10 or
ubiquinone.
Answer:
The correct answer is D reduce environmental stimuli
Explanation:
Respiratory acidosis occur when a person is exposed to an atmosphere contain high amount of Carbon dioxide.As a result the carbon dioxide enters within the person"s body and reacts with water molecule to form carbonic acid(H2CO3).This ultimately leads to decrease the blood pH causing respiratory acidosis.
Respiratory acidosis can be treated by moving that person to an atmosphere containing very low amount of carbon dioxide,as a result to maintain homeostasis the carbonic acid present in the body will under breakdown to generate water and carbon dioxide.Thus the concentration of carbonic acid can be reduced which result to increase the blood pH.
The answer is C; Many copies of a DNA Fragment
The specific DNA sequence has been doubled. This cycle of Denature-Anneal-Extend is repeated, usually about 35 times, by using a thermocycler over 2-3 hours (the "chain reaction" of PCR). This produces 34,359,738,368 copies of DNA (That's 2^35)!
