Answer:
(46)
Explanation:
in a humans, each cell normally contains 23 pair of chromosomes, for a total of 46, these pairs, called autosomes, look the same in both males and females.
Answer:
The oxygen atoms of CO2 originated from glucose and the oxygen atom of H2O is originated from normal oxygen molecule that act as reactant during the break down of glucose by oxidation.
Explanation:
C6H12O6+6O2=6CO2+6H2O+Energy
In the above reaction glucose is being reduced to generate CO2 .As a result the oxygen of CO2 is originated from glucose.
The above also deals with the reduction of oxygen to H2O.From that point of view it can be stated that the oxygen atom of H2O originates from molecular oxygen that act as reactant.
<u>Answer:</u>
The alternative complement pathway kill the invading microbial cell by enhancing the phagocytosis of microbes by host cells.
Option: (C)
<u>Explanation:</u>
-
The complement pathway is an immune system which destroys the microbes with protein complex and phagocytes.
- It has tree types namely 'classical, alternative and lectin pathway'.
-
In alternative complement pathway complex
protein complex kills the microbes in two ways,
- It attaches to the cell wall of the bacteria and kills by lysis
- Stimulates the formation of "Membrane Attack Complex(MAC)" which causes lysis of the bacteria.
Answer:
C
Explanation:
<em>A person with garbled speech may have experienced damage to the frontal lobe portion of the brain.</em>
<u>This is because the left portion of the frontal lobe of the brain is an area that has been touted to be responsible for the control of speech in humans. Research in the past has shown that damage to that region of the brain affects the formation of spontaneous speech as well as motor speech control.</u>
Hence, garbled speech in someone that has experienced stroke can be attributed to damage to the frontal lobe.
Correct option: C.
Answer:
The correct answer is C the extraction of high energy electrons remaining from glycolysis and citric acid cycle .
Explanation:
Electron transport chain(ETC) occur in mitocondria and is the last process of aerobic respiration.ETC deals with the transfer of electron from the reducing equivalent such as NADH,FADH2 thereby oxidising them to their oxidized form NAD+,FAD.
The liberated electron from these equivalents utilizes the proton motive force come from the transport of H+ ion cytosol to mitocondrial matrix and then result in the phosphorylation of ADP to form ATP along with H2O by the reduction O2.
