Answer:
Chromosomes are systemized structures of proteins and DNA. It have a string like shape, mainly located within the nucleus of both plant and animal cells. DNA is concentrated in the chromosomes. In 1902, Sutton and Boveri proposed that chromosomes has a part in heredity opposing Mendel's theory of segregation and independent assortment.
One major function of the chromosome is to keep the DNA from being altered or negatively influenced during cell division. It ensures accurate distribution of the DNA during the breaking down of genetic material. In mitosis, the chromosomes are duplicated and dispersed to daughter cells so that each cell attains a diploid set of chromosomes totally of the same nature to that of its parent cell. In meiosis, the resultant cells would attain a chromosome from each chromosome pair this will lead to half the number of chromosomes. This process is important for the offspring being produced to have the same characteristics of the parents which would results from the fusion of the sperm and egg of the parents.
Specialized ganglionic sympathetic neurons that release hormones into the bloodstream are found within the adrenal glands.

What is adrenal gland?</h3>
- A little gland that produces noradrenaline, adrenaline, and steroid hormones.
- These hormones assist in maintaining healthy blood pressure, heart rate, and other vital bodily functions.
- Immune system, blood pressure, stress response, metabolism, and other critical processes are all controlled by hormones that are produced by adrenal glands.
- The cortex and the medulla, the two components that make up an adrenal gland, are each in charge of manufacturing a separate hormone.
- Problems with one, both, or other glands, such as the pituitary gland, can result in diseases of the adrenal glands.
- When the adrenal glands create either an excessive amount of hormones or an excessive amount of hormones from external sources, several diseases may arise.
- Since the adrenal glands are essential for human survival, if both are destroyed, the patient will need to take drugs and hormone supplements.

Answer:
in cellular respiration food is oxidized to CO2 while O2 is reduced into H2O Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration.Aerobic respiration, the process that does use oxygen, produces much more energy and doesn’t produce lactic acid. It also produces carbon dioxide as a waste product, which then enters the circulatory system
Answer: b. Mendel's law of independent assortment.
Answer:
The complex eukaryotic cell ushered in a whole new era for life on Earth, because these cells evolved into multicellular organisms. Evidence supports the idea that eukaryotic cells are actually the descendents of separate prokaryotic cells that joined together in a symbiotic union.
