Based on the Scenario, the process is described as Mitosis

During this process  , chromosomes in a cell nucleus will be separated into two identical set of chromosomes (which make it four) and will end up in their own nucleus 

hope this helps

Answer:

The process described here is Mitosis.

Explanation:

During mitosis the parent cell divides into two daughter cells which are identical to each other and to the parent cell. Mitosis increases the cell number. The number of chromosomes remains the same. During mitosis the DNA is duplicated in the parent cell and then passed on to the daughter cells.  There are five phases of mitosis i.e. Prophase, Metaphase,Anaphase, Telephase and interphase.

There are three ways sexual reproduction increases genetic diversity in a species. Choose two and explain each
Yuki888 [10]

So in order to form a new organism, two gametes -- the sex cells, sperm and egg -- must fuse, further mixing the genes to produce more genetic diversity. Asexual reproduction is one organism dividing into two organisms without shuffling its genes, so the offspring has the same version of genes as did the parent.

What roles do polysaccharides play in living things?
AVprozaik [17]
The appropriate answer is D. storing sugar and providing structure. Polysaccharides are complex carbohydrates. Starch, glycogen and cellulose are polysaccharides in which the constituent molecules are made of several thousand glucose units linked in long chains. Glycogen is vital to nutrition because it is how the body stores excess glucose in muscles and in the liver.
The molecular structure of glycogen is similar to starch except that the polysaccharide chains are longer and more branched than in glycogen.

Although janay's brain makes up only about ____ percent of her total body weight, it uses about _____ percent of the total oxyge
In-s [12.5K]
The brain represents 2% of the total body weight for a human. But it uses 20% of the total oxygen and calories absorbed by the body (so ten times more than its weight ratio) it proves that it is an important organ that need a lot of energy.

The brain is the seat of higher functions (cognitive functions, senses, nervous responses) and vegetative functions. It is, therefore, an essential organ that regulates all vital functions. Like a central unit in a desk computer, the brain receives information from the entire human body via afferent nerves, integrates and analyzes them, and responds by emitting new signals that descend to the parts of the body concerned by the efferent nerves.

At the moment of sperm penetration, human eggs ______. A. have used flagellar propulsion to move from the ovary to the oviduct B
marshall27 [118]

During sperm penetration, human eggs are still surrounded by follicular cells.

Therefore, the correct answer is Option D.

<h3>What changes does egg undergo for fertilization?</h3>
  • An egg goes through a few changes at the hour of sperm penetration during fertilization.
  • These progressions happen at the cell surface, in development, physiology and gene expression.
  • For fertilization, a sperm should combine with the cell membrane and afterward infiltrate the egg cells.
  • Infiltration through the egg cell or extracellular matrix (ECM) is a troublesome task.
  • The acrosome of the egg goes through acrosomal reaction to get through the hard shell of cell.
  • To go through the follicle cells encompassing the egg or oocyte, the sperm discharges hyaluronidase enzyme.
  • This chemical isn't delivered until the sperm comes into contact with the egg cell's zona pellucida.
