<span>Proteins are composed of α-amino acids linked together by peptide bonds into polypeptide chains. An amino acid is characterized by an amino group (-NH2) and a carboxylic acid group (-COOH) linked to a carbon, known as the α-carbon. Also attached to the α-carbon is a H and various R-groups or "side-chains".</span>
Answer:
The correct answer is option B, that is, Calvin cycle.
Explanation:
The light-independent reaction or photosynthetic carbon reduction of photosynthesis is termed as the Calvin cycle. In this reaction, the compounds get transformed to glucose, and at the same time regenerated ribulose bisphosphate gets produced as the end product with ADP from ATP.
ADP is obtained from the molecules of ATP, and 1 molecule of glucose is generated as the end product in the reduction phase of the process. On the other hand, in the regeneration phase, the molecules of RuBP regenerates and the molecules of ATP get convert again to the molecules of ADP.
The electrochemical impulse is composed of an action potential travelling from the dendrite to the cell body to the axon of the neuron. The main neurotransmitter is acetylcholine which is released at either the synapse or the neuromuscular junction.
Answer:
The addition of a chromosome in an egg cell.
Explanation:
Mutation may be defined as sudden, heritable change in the DNA sequences. The mutation may be caused during the DNA replication or may be caused by the environmental factors.
The mutation that occurs in the gametic cells may pass down from parents to their offspring. The addition of an extra chromosome in egg cell will be inherited in the next generation.
Thus, the correct answer is option (C).
The prevailing public consensus regarding species evolution
was that species were
permanent and unchanging, prior to the publication of Charles
Darwin's book, On the Origin of Species,
On the Origin of Species, is a work of
scientific literature by Charles Darwin which is considered to be the
foundation of evolutionary biology.
