All of the above i think.
Answer:
a) the oxidizing agent.
Explanation:
In the citric acid cycle, malate is dehydrogenated into oxaloacetate and the reaction is catalyzed by malate dehydrogenase. The released electrons are accepted by NAD+. So, NAD+ is reduced into NADH. The substances that accept electrons during chemical reactions and are reduced to oxidize the other substances are called oxidizing agents. NAD+ serves as an oxidizing agent as it accepts electrons to oxidize malate into oxaloacetate.
Answer:
A new mutation
Explanation:
A mutation refers to the random changes in the DNA of organisms. A mutation changes the allele and genotype frequencies by the introduction of a new allele in the gene pool.
However, mutations are not the major factor responsible for changes in the gene pool of a population as mutations are rare. The rate of mutations is very slow and does not allow it to serve as a major factor to change the allele and genotype frequencies.
Chromosome count of the stem cell that produces the gametes 96
Answer:A. club
Explanation:
Fungi are eukaryotic organisms .they are feed on dead, decaying matter because they lack chloroplast. Most fungi are parasitic or symbiotic.
Fungi lacks root, stem and leaves. They however posses threadlike filaments called hyphae, which forms a larger mass called mycellium. Fungi reproduce asexually by spores. The classification of fungi are;
#zygomycetes, also called conjugation fungi .eg bread mold
#ascomycetes, also called sac fungi eg baker's yeast
#deuteromycota, also called imperfect fungi eg penicillium
#basidiomycetes .they are the commonly known mushrooms. They grow on wood and trees. Most of their species are edible. They are also called club fungi
