Answer:
Velocity
Explanation:
Given the change in positive (direction) over time we are given the velocity formula.
V = Change in direction/Change in time
Since we are given a direction we can rule out speed as well as direction in itself. We can also rule out acceleration because that is the change in Velocity divided by change in time.
Answer:
D
Explanation:
Because there has to be competition or one population wouldnt decrease and the other wouldn't increase due to survival and reproduction the population doesn't always have to be below the carrying capacity because it can also do it when its above and natural selection can act on traits determined by different alleles.
Answer:
A and D
Explanation:
Dolphins have a narrow, torpedo-shaped body to swim easily through water. Their strong, paddle-like flippers also aid in strong swimming.
However dolphins do not secrete gases or attach themselves to the bottom of the sea, so the answers are A and D.
Good luck ^^
Color patterns can be thought of as mosaics of different-sized, form, brilliant, and colored patches. A number of natural conditions, including ambient light, watercolor, viewing distance, and the visual capabilities of guppies and three of their predators, were used to assess how noticeable guppy color patterns were.
A particular color pattern element (patch reflectance )'s spectrum, the medium's transmission spectrum, and the ambient light spectrum that strikes the patch all interact to determine the light spectrum that reaches the eye's surface (air or water).
The light at distance x from the patch that reaches the eye at any given wavelength, I, is the result: Q(& x) is the photon flux from the patch reaching the eye (patch radiance), and Q(A) is the photon flux of ambient light incident on the patch.
Predation intensity varies spatially with guppy color patterns, which are influenced by the make-up of the predator communities (Endler, 1978). As a result, calculations were made independently for the color patterns of guppies that are unique to three different predator communities.
