Answer:
<h2>A</h2>
Explanation:
1. Nucleus is a ball like structure which is found in the center of the cell only in eukaryotic cell, true nucleus is absent in prokaryotes.
2. Nucleus contains nucleic acid and is have double membrane which contain pores though which transport of molecules occurs.
3. DNA replication , transcription and RNA splicing occur in the nucleus.
Answer:
Lack a nucleus
DNA is found in the Nucleoid
They have a cell wall
Explanation:
Answer:
The correct answer is A. Substrate-level phosphorylation
Explanation:
During the substrate-level phosphorylation, phosphoryl group is directly added to ADP or GDP to form ATP or GTP from phosphorylated intermediate rather than from inorganic phosphate like in case of oxidative phosphorylation.
So in glycolysis 4 ATP are produced by substrate-level phosphorylation. Apart from the 4 ATP, 2NADH are also produced during the glycolysis which is used during the oxidative phosphorylation and produce 4-6 ATP.
So ATP made during glycolysis is generated by substrate-level phosphorylation as ATP is produced by direct addition of phosphoryl group from intermediates.
Answer: Natural Selection. Natural Selection leads to an evolutionary change when some individuals with certain traits in a population have a higher survival and reproductive rate than others and pass on these inheritable genetic features to their offspring.
