Answer: SPORES are defined as haploid (1n) cells which develops into gametophytes.
Gametophytes inturn produce either haploid (1n) male or females GAMETES that can fuse to form diploid ZYGOTES.
This basically explains what goes on in Meiosis.

Low amounts of adrenaline, secreted within 30 seconds of learning, have a role in the consolidation of memory. Emotions that produce adrenaline therefore have an effect on the strength of a newly forming memory. The memories that are formed under circumstances of emotional arousal are often vital to survival.
Answer:
In the given sequence of chromosomes to represents the centro-mere is ABCDEFG.H AEDCBFG.H.
In case of crossing over among B and C, made recombinants will be;
1) ABCDEA
2) H.GBCDEFG.H
However, out of these two made crossover chromosomes, only 1st recombinant chromosome as ABCDEA is the straight recombinants chromosome
.
Answer:
(D) acetyl CoA, NADH, H+, and CO2.
Explanation:
The given explanation is about oxidative decarboxylation of pyruvate into acetyl CoA and carbon dioxide. The reactions are catalyzed by enzyme complex pyruvate dehydrogenase. During the reaction, pyruvate loses one of its carbon atoms in the form of CO2 and the rest of two carbons form the acetate which in turn combines with CoA to form the acetyl CoA.
Since it is an oxidative decarboxylation, the released electrons are accepted by NAD+ which in turn is converted into NADH + H+.
Overall, there is the formation of one molecule of acetyl-CoA, CO2 and NADH + H+ each from one molecule of pyruvate.
