Answer:

chitin and murein

Explanation:

The chemical compounds that distinguish bacteria cell from yeast cell are  

chitin and murein

Chitin is a polysaccharide present in the exoskeleton of fungi made up of chains of modified glucose known as N-acetylglucosamine. N-acetylglucosamine is derived from glucose

While murein is a mesh like structure made up of sugar and amino acids. Murein forms a layer outside the plasma membrane of bacterial cell.

Answer:

Peptidoglycan and chitin.

Explanation:

Bacteria and yeast differ from each due to the different chemical composition of their cell wall.

Chitin: chitin is a large structural polysaccharide that is derived from chains of modified glucose. It is the primary components of cell wall in fungi such as yeast. Chitin is a minor component in the yeast cell wall, it accounts for only 1-2% of the cell wall dry mass. Chitin contributes to the mechanical strength of the cell wall.

Peptidoglycan: Peptidoglycan also known as murein is a polymer that makes up a the cell wall of a bacterium. It is composed of sugars and amino acids. A bacteria is a unicellular organism, therefore Peptidoglycan gives strength to the outer structure of the organism.

Answer:

During <u><em>vegetative propagation</em></u>, a new plant grows from parts of the parent plant.

During<u><em> mitosis</em></u> , a new plant grows from parts of the parent plant.

Explanation:

<em>Asexual reproduction can be described as a type of reproduction in which only one parent is involved and the daughter cells formed are identical to the parent cell.</em>

In vegetative propagation, a vegetative part of the plant such as roots, shoots etc are taken and grown separately. A new plant arises from these parts of the plant.

Mitosis is a type of asexual reproduction in which only a single cell undergoes division to produce two new daughter cells which have the same genetic makeup as the parent cell.

GrogVix [38]

Answer:

Origin of Species was a book that was published in 1859 by Charles Darwin on human evolution. This theory was based on natural selection.

Explanation:

The evolution theory was first proposed by Darwin in 1856 in his book Origin of Species. In this theory, Darwin explains the changes in species over time result in the changes in the traits and heritable qualities. Evolution occurred by natural selection. In this theory, scientists show two main points that, all species are connected on this earth and the diversity in the population is the result of the modification in traits by time.

For Example, one study on 1900 students on human evolution was published in the journal " Personality and Individual Differences". According to this research, people are hard to find their soul mate because the changes are very rapid in traits.

List the reasons why food chains to not send to exceed 4 links
Hitman42 [59]
As the number of organisms increase so does their tropic levels. As one organism eats the other energy is being transferred to that organism. The larger the food chain the lesser the organism' s would be because they would lose energy while trying to hunt and catch their prey and other activities. The food chain usually ends at the tertiary consumer or the fourth link because if it goes on like that there would be less energy hence these organisms would most likely starve and gradually die.
