Kyle had a brother who exhibited heart disease at age 62 and a sister who exhibited heart disease at age 64. based on the age at which his brother and his sister exhibited heart disease, is kyle considered to have a family history of heart disease?

Yes, Kyle has a family history of heart disease.

Explanation:

A family history is a record of health information about a person and their close relatives. Having relatives with a health problem does not mean that you will develop this condition, but the chances increase. This is because families have many factors in common, including genes and often the environment and lifestyle.

Two of Kyle's brothers developed heart disease, so we can say that Kyle has a family history of heart disease.

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.
