Explain the relationship between mutations adaptations, natural selection
and extinction

Answer:

Natural selection is where positive traits survive more, allowing those to become more common. Mutation is where radioactivity changes genes in a random way. Natural selection allows positive mutation to become more common. Adaptation is where natural selection works for a species specifically more a new habitat.

In the human body, is every organ a part of only one organ system? Or are some organs a part of two or more organ systems? A. Every organ is a part of only one organ system, which is necessary because organ systems work independently of one another. B. Every organ is a part of only one organ system, although organ systems often interact with one another. C. Some organs are a part of two or more organ systems. For example, the heart is a part of the circulatory and digestive systems. D.

A golfer collected data on the distance a gold cart traveled in a straight line and plotted it on a graph

A student examining an unknown cell under a microscope notes it has a cell wall, cytoplasm, and genetic information contained within a nuclear membrane. Which inference would be correct?



Since the cell possesses a cell wall and genetic information, it has to be an animal cell.

Since the cell contains genetic information, it has to be a bacteria cell and prokaryotic.

Since it possesses a cell wall and DNA contained in a nuclear membrane, the cell must be eukaryotic.

Since the DNA is contained in a membrane and not in the cytoplasm, the cell must be a plant cell

Which of the following best describes the flow of energy in the Everglades food web shown below? (4 points)

Diagram for an everglades food web. The food web contains the following organisms: American alligator, egret, raccoon, carp, Key deer, insects, Southern leopard frog, mangrove, and sawgrass. Mangrove is at the bottom of the food web, with arrows pointing to Key deer and insects. Sawgrass is also at the bottom of the web, with an arrow pointing to insects. Key deer, insects and Southern leopard frog are on the next level up. The Key deer has an arrow pointing to American alligator. The insects point to egret, carp, and Southern leopard frog. The Southern leopard frog points to the American alligator and the raccoon. The egret, carp and raccoon all points upward toward the American alligator. The carp also points to the egret. The American alligator is at the top of the food web.

a
Egret → insects → mangrove → key deer → American alligator; about 90 percent of the energy in one trophic level is transferred to the next trophic level.

b
Mangrove → insects → carp → American alligator; about 90 percent of the energy in one trophic level is transferred to the next trophic level.

c
Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.

d
American alligator → carp → insects → mangrove; about 10 percent of the energy in one trophic level is transferred to the next trophic level.
