All cells share four common components: 1) a plasma membrane, an outer covering that separates the cell's interior from its surrounding environment; 2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; 3) DNA, the genetic material of the cell; and 4) ribosomes, .

Answer:

If you are referring to the image below, the answers would be:

Monosaccharides:

  • Galactose
  • Glucose
  • Ribose
  • Deoxyribose
  • Glyceraldehyde
  • Fructose

Disaccharides:

  • Maltose
  • Sucrose
  • Lactose

Storage Polysaccharides:

  • Starch
  • Glycogen

Structural Polysaccharides:

  • Chitin
  • Cellulose
  • Amylopectin
  • Amylose

Explanation:

Monosaccharides are simple sugars, typically having 3 to 7 carbons in its structures. Aldoses and ketoses are forms of monosaccharides. If a monosaccharide has a aldehyde, it is an aldose. If a monosaccharide has a ketone, it is a ketose. You also have other forms, depending on te number of carbons. (e.g. Tioses, hexose and pentose)

Disaccharides are two monosaccharides bonded covalently through a glcosidc bond. They form through a condensation reaction, specifically through dehydration synthesis. Thus, the name "di" saccharides.

Polysaccharides are complex carbohydrates that are made up of many monosaccharides. Their functions are mainly storage and make up the structure of tissues.

Storage polysaccharides are polysaccharides that act as food reserves or energy reserves. They are called storage because they are stored away for later use. Starch is a storage polysaccharide that is found in plants and glycogen on the other hand, is found in animals.

Structural polysaccharides help form the structures of cell walls in plants and skeletons in animals. The most common ones are chitin and cellulose.

ICE Princess25 [194]
Bacteria can be classified as the two obvious answers here! Archaebacteria, and Eubacteria. Hence "bacteria" suffixing them, and then the three other options do not make sense, and are not a classification.

Organisms that complete the final breakdown and recycling of organic materials from
scoundrel [369]

Answer:

decomposers

Explanation:

These are heterotrophic organisms that feed on dead animals and plants, secretions, or discarded parts of living beings, that is, organic matter.

And they break it down into inorganic.

Thus, inorganic substances that can be reused in the process of photosynthesis are returned, recycled, to nature.

algol13

Answer:

Organism having the suitable traits appears more in the population.

Explanation:

Natural selection is a non-random process in the biological traits becomes less or more common in the population due to the different rate of survival of their bearer or their differential reproduction.  

Natural selection leads to evolution because those organisms are selected to survive and reproduce which are having those traits that are better suited to a certain set of environmental conditions over others. As a result, the number of these organisms increases over time and they appear more in the population.

So natural selection leads to evolution as an organism having the suitable traits appears more in the population.
