Which statement best describes the movement of ocean waves? Water moves across the ocean's surface water remains in the same pla

Andreyy89

Answer:

water remains in the same place as wave (energy) travels through it

Explanation:

Winds influence the ocean and its movements. Air current running on the ocean surface transfers energy to water. A <u>wave is nothing else than energy</u>. When the winds provide energy to the water surface and produce waves, it occurs a particular water molecules´ motion. They move in circles from up to down, up to a certain depth, and go back to the surface. And they do so while energy from the wave is passing through. Waves are the ones that move through the ocean until they reach the shore, where the energy is transferred to land. Water molecules remain in the same general area, while energy travels from molecule to molecule as a wave.

Explain how birth rate and death rates influence the size of a population. (Discounting migration in/out of a population.)

Galina-37 [17]

Answer:

Explanation:

As the population size approaches the carrying capacity, the growth rate slows because of the falling birth rate and the increasing death rate. When a population reaches its carrying capacity, the birth rate equals the death rate, and growth stops.

Interpret the Punnett square. A Punnett square with four rows and four columns. The first row is labeled big-A, big-B. The secon

Naddika [18.5K]

Answer:

The genotypes shown represent gametes. False

One of the possible offspring genotypes is AABB. True

The parent genotypes are ABAbaBab×ABAbaBab. True

This cross shows two alleles for two traits. True

The gametes are diploid and the offspring are diploid. False

The genotypes shown are correct for a dihybrid cross. True

Explanation:

║ AB ║ Ab ║ aB ║ ab

AB║ABAB ║ ABAb║ABaB║ABab

Ab║ AbAB║ AbAb ║AbaB║Abab

aB║aBAB ║ aBAb ║aBaB║aBab

ab║abAB ║ abAb ║abaB ║abab

Drawing the Punnett square we can deduce that the genotypes shown do not represent gametes because there are more than 2 pairs of chromosomes.

As shown in the second column second row of the Punnett square one of the possible genotypes is AABB, it is distributed different (ABAB) but it is the same possible genotype.

The parents' genotypes are the ones that are written in the first columns and first row, they coincide with the ones in the statement.

A dihybrid cross shows the cross between two genes that have different traits.

The gametes are always haploid and the offspring are diploid because the two gametes come together.
