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:
chemotaxis
Explanation:
Chemotaxis is movement of the organism in the response to the chemical stimulus.
Bacteria, somatic cells and single-cell as well as multicellular organisms direct movements of their body according to some chemicals in the environment. This is very important for the bacteria to find the food by swimming toward highest concentration of the food molecules or also to flee from the poisons.
<u>Thus, it is a process by which various cells are drawn to the target area by a microbe invader.</u>

Answer
When a eukaryotic cell is not undergoing mitosis, the DNA and its associated proteins appear as a visible network of dark fibers called the Chromatin.
Definition
Chromatin is a thread like structure that can be seen inside nucleus before cell division. It is a complex of DNA and histone proteins.
Forms of chromatin
Chromatin exist in two forms, that is
a. Euchromatin
It is less condensed and can be easily transcribed.
b. Heterochromatin
It is highly condensed and not transcribed as easy.
Organization of chromatin
Microscopy has shown the appearance of chromatin as beads on a string. The beads are called nucleosomes.
Nucleosome
Each nucleosome is composed of DNA wrapped around eight histone proteins. The nucleosome is then wrapped into a 30nm spiral called solenoid.
