Answer:
D
Explanation:
Particles move from a region of higher concentration to a region of lower concentration until the molecules are evenly contributed
Answer:
B. recycle NADH back to NAD+
Explanation:
Both respiration and fermentation share a common pathway, that is glycolysis. The redox reactions of glycolysis use NAD+ as an electron acceptor and NADH is formed. To continue the process of respiration and fermentation, oxidation of NADH into NAD+ is required so that NAD+ can serve as an electron acceptor for glycolytic reactions.
Aerobic respiration oxidizes NADH into NAD+ by transferring its electrons to the terminal electron acceptor, the molecular oxygen. On the other hand, fermentation oxidizes NADH through the formation of lactic acid or ethanol from pyruvate.
The diploid number of chromosome for a karyotype containing 47 chromosomes will be 23 XYX8.
Explanation:
In Trisomy 8 syndromes the individual has three copies of number 8 chromosome.
The karyotype is 23 XYX8.
Usually the normal organism has 2 number of eighth chromosome.
The trisomy occurs because of non disjunction in meiosis in the germ cells.
Answer:
there are 4 steps in the carbon cycle
Photosynthesis, Decomposition, Respiration and Combustion. Carbon cycles from the atmosphere into plants and living things.
