Answer: Biodiversity hotspots are home to nearly 20% of the world's population. Option B is most accurate.

Explanation:

A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation.

Biodiversity hotspots host their diverse ecosystems on just 2.3% of the planet's surface, however, the area defined as hotspots covers a much larger proportion of the land, so much that it hosts about twenty percent of the world's population.

VARVARA [1.3K]

Answer:

The main job of red blood cells, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs. Hemoglobin (Hgb) is an important protein in the red blood cells that carries oxygen from the lungs to all parts of our body.

Which statement best defines a protist?
Helga [31]
Protists obtain food in 3 ways. They produce their own organic molecules, ingest, and absorb.  Ingestive protists ingest food, or engulf bacteria. These protists extend their cell wall and cell membrane forming a food vacuole around the food item. Inside the food vacuole, enzymes digest the food. Absorptive protists on the other hand, absorb food molecules  across their cell membrane which takes place through diffusion. Absorptive protists play a key role in decomposition. They are considered as important decomposers. Major producers  like photosynthetic protists  use light energy to manufacture  their own food.<span>

Pepsi [2]

Answer: The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties.

Explanation:

Starch and Cellulose flare both polysaccharides which are constructed from the same monomer called glucose. The functions they provide in plants are different which includes the following:

- STARCH is used by plants for energy storage because unlike Cellulose, it's formed from glucose units( oriented in the same direction) connected by alpha linkages which can form compact structures that can easily be broken down.

- Cellulose provides structural support for plant cell wall because unlike Starch, it's formed from glucose units( which rotates 180 degrees around the axis of the polymer backbone chain) connected by beta linkages. This pattern gives Cellulose it's rigid features as is allows for hydrogen bonding between two molecules of Cellulose.

Therefore the statement that best describes why starch and cellulose provide different functions in plants is that (The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties).
