Answer:
B. 0 m
Explanation:
From the position - time graph, the object would have traveled a distance of 0m after 6s.
The graph shows a decrease in distance traveled with increasing time.
- the y - axis is the position of the body
- the x - axis is the the time taken
If we trace up the time taken to the curve, the position will be 0m.
Therefore, the position of the body after 6s is at 0m.
Answer:
Species 28 and 14
Explanation:
Take the species that has the greater number, and the subtract it with the number of the other species. Then you would be able to see how many new species evolved between them.
The cell will gain water because there is 35% outside, and only 25% is inside. So, the arrow will be drawn as water going into the cell. The cell will gain mass because the cell will gain water. It's a hypotonic situation because the cell is gaining water.
The cell wall, capsule, pilus, and flagella are the bacterial structure that is located on the surface of a bacterial cell.
Cell wall: It is composed of a protein-sugar(polysaccharide) molecule which gives the cell its shape, and rigidity and protects it from the environment.
Capsule: It is a third protective covering that is made up of polysaccharides. It plays many roles but the important ones are to keep the bacterium from drying out and to protect it from engulfing by larger microorganisms.
Pilus: These are specifically small hairlike projections that emerges from the outside of the cell surface. It helps bacteria to attach to the host organism.
Flagella: (singular, flagellum) a hairlike structure that provides a means of location for bacteria. These are mainly found at either or ends of all over its surface.
