Answer:
See the answer below
Explanation:
Person X is feeling a burning sensation in several muscles<u> because of the accumulation of lactic acid due to inadequate oxygen in their system.</u> When oxygen becomes inadequate during exercises, anaerobic respiration takes place to augment the oxygen shortage and this leads to the production of lactic acid which accumulates up in the muscles and gives a burning sensation.
Person Y does not feel any burning sensation in their muscles <u>because oxygen is adequate in their system and they do not need to respire anaerobically.</u> <em>Person X exercise regime must have been more rigorous than that of person Y.</em>
Answer:
The correct answer is option C.
Explanation:
Before meiosis, DNA that is stacked into chromosomes must replicate. Before replication, the sex cell has two copies of each chromosome, one from mother, and one from father.
DNA replication takes place in the same manner as it does during mitosis. After the chromosome replication, the homologs are double in number, and each chromosome now has a homologous pair of chromosomes.
Thus, the correct answer is option C.
Answer:
An Endoplasmic reticulum
Explanation:
A living organism can either have prokaryotic or eukaryotic cells.
Eukaryotic cells have a defined nucleus and other membrane bound organelles whereas prokaryotic cells lack membrane bound organelles such as mitochondrion and chloroplast.
Endoplasmic reticulum are membranous system that forms a system of flattened sacs in the cytoplasm.
These organelles can only be found in eukaryotic cells and not prokaryotic cell.
