Which statements describe solstices? Check all that apply.

A) They occur when the Sun reaches its highest or lowest point in the sky.

B) They affect the amount of sunlight in the Northern Hemisphere in June.

C) They contribute to the cycling of winters all year long in the Northern Hemisphere.

D) They influence the cycling of different seasons based on the Sun’s height in the sky.

E) They increase the amount of rays from the Sun directly received in the Southern Hemisphere.

Solution

Solstices occur twice in a year. One during summer in the month of June and the other during winters in the month of December. This happens only when the north pole and south of the earth is tilted towards the sun and is closest alternatively during summer and winter. At this position, the sun rays fall directly on the tropic of cancer during summer and Tropic of Capricorn respectively. Solstices  signals the change of seasons on planet earth along with equinox.

Hence, option A, B and D are correct

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.
