Answer:
Option A, Key stone
Explanation:
A keystone species plays a major role in an ecosystem as it is the species whose presence effects all other species in the ecosystem .In general a keystone species is always a dominant predator that feed on prey population. If it is removed, the prey population will explode and the population diversity will reduce. For example - bison, prairie dog etc.
Hence, option A is correct
<h2>Answer is option "C"</h2>
Explanation:
- NAD+ is a significant co-compound for hydride move catalysts fundamental to numerous metabolic procedures including glycolysis, pyruvate dehydrogenase complex, the TCA cycle and oxidative phosphorylation. The catalysts utilizing NAD+ in hydride-move are known as dehydrogenases or oxidoreductases, which catalyze the decrease of NAD+ into NADH
- NADH shaped from glycolysis (by means of the malate-aspartate transport) or the TCA cycle can respond at Complex I, otherwise called the NADH/coenzyme Q reductase in the mitochondrial electron transport chain [28]. Each NADH devoured by the mitochondria brings about the net creation of 3 ATP atoms (Figure 1). The total oxidation of one glucose atom creates 2 NADH reciprocals in cytosol and 8 NADH particles in mitochondria, empowering creation of 30 ATP counterparts from NADH of the aggregate of 36 ATP counterparts got from the entire procedure of catabolizing glucose to CO2 and H2O.
- Hence, the right answer is option C " the available NAD+ would be converted to NADH and glycolysis would stop due to lack of NAD+.

Question in English:
The concept of gene flow is demonstrated when a cow is expelled from her herd, joins another herd, and reproduces. When the cow contributes to the gene pool of the new herd, which of these is most likely to increase?
A. Natural selection
B. Genetic variation
C. Environmental suitability
D. Reproductive mutations
Answer:
B. Genetic variation/Variación genética
Explanation:
When an organism from one population enters a new population that does not normally mix, it brings with it its own unique genetic variation.
Its new alleles are introduced into the new population when the cow breeds, enhancing the amount of gene variation in the new herd. This is how gene flow increases variation
