Answer:

Crossing over is the substitution of genetic material in the germline. When egg and sperm cells, also known as meiosis, are formed, paired chromosomes are arranged from each relative in such a way that identical DNA chromosome sequences cross over each other.

Crossing resulting in genetic material shuffling is a significant cause of the genetic difference between descendants.

ankoles [38]

Answer:

Carrying capacity for the jellyfish would reduce

Explanation:

Carrying capacity of a biological population in an ecosystem is the maximum number of population size the environment or habitat can conveniently cater for given the available resources such as, food, water supply, space etc.

The survival of the jelly fish largely in the small body of water would be largely dependent on how much food that is available.

The large number of mollusks harvested would reduce the available food in the small body of water, hence, reducing the carrying capacity for jellyfish.

Which of the following best describes the influence of latitude on climate? A. Earth's climate zones are produced by the equal d
mixas84 [53]
D. Polar regions receive less solar energy and heat per unit area than tropical regions 

Less direct sunlight means that there is less concentration of direct solar rays. This would influence temperature and would ultimately create weather, and since this pattern continues of switching direct ray latitudes, this would create climate zones all over the Earth, and similar ones with similar latitude and terrain.

The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.

Explanation:

In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.
