Explain how the process of asexual reproduction works. What events must a cell go through to successfully

Answers

Answer 1
Answer:

Answer and Explanation:

In asexual reproduction, one or more freely existing organisms arises from a single parent. There are different types of asexual reproduction.

  1. Fission- this is a process by which a single-celled organism divides into two or more roughly equal parts. Binary fission is the division of an organism into two daughter cells.
  2. Spores formation- spores are unicellular bodies formed by cell division in parent organisms. When detached from parent, they germinate and grow into new individuals.
  3. Budding- it is a modified form of fission in yeasts. A small area of the cell wall of the parent cell softens and forms a protrusion. This enlarges until it is almost equal to the mother cell. The nucleus divide by mitosis. a constriction develops between the two which then separate.
  4. Vegetative production- it refers to the process whereby, a portion detached from a parent plant develops into a new self-sustaining plant.

What is a peptide bond

Answers

The bond that connects two amino acids

A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water.

Which best describes the difference between osmosis and diffusion? Osmosis is the movement of particles from a high to a low particle concentration, while diffusion is the movement of water from a high to a low water concentration.
Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration.
Diffusion is the movement of particles from a low to a high particle concentration, while osmosis is the movement of water from a low to a high water concentration.
Osmosis is the movement of particles from a low to a high particle concentration, while diffusion is the movement of water from a low to a high water concentration.

Answers

Answer:

Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration.

Explanation:

Osmosis refers to the movement of water molecules through a selectively permeable membrane. The movement always occurs from the region of higher concentration of water to that of lower concentration. Osmosis does not include the movement of solutes.

Diffusion is the movement of substances from higher to lower concentration region. Diffusion is not restricted to movement of water only.  
It would be the second one where osmosis is the movement of water from high to low and diffusion is the movement of particles from high to low

Discuss two ways that all cells are alike?

Answers

Well,

First, all cells must have DNA in order to function.  Without DNA a cell could not possible perform basic life functions, such as biosynthesis, absorption, and reproduction, among the innumerable others.

Second, all cells have ribosomes, as proteins are very significant and vital to every cell.  Ribosomes are primarily responsible with protein synthesis.  Even in prokaryotic cells, ribosomes are present.

What are the purposes of Villi?

Answers

The function of villi, small finger-like projections in the intestines, is to allow for more surface area in the small intestines. This way, absorbing nutrients from digested food into the blood would improve greatly. Although they do not help in digestion, they are still important parts of the digestive system.  
well the main purpose of the Villi (small intestine's surface) is to help increase the surface area for the intestine. Because the bigger the surface area the more it has for absorbent. And this plays a huge part because  the food that we eat has vitamins and nutrients that your body needs to function properly. 
hope this was helpful:)
