Myra has an apple. which of the following tools could myra use to measure the gravitational force being exerted on the apple? a. a graduated cylinder b. a triple beam balance c. a spring scale d. a metric ruler

As Myra needs to measure the gravitational force on the apple, a triple beam balance would be ideal to measure it.

The measure of the gravitational force on or near the Earth’s surface is its weight. This is the force of gravitation exerted by any object on Earth. Mass of an object determines its gravitational force. The force of gravitation or the measure of the weight is numerically equal to the product of mass of the object and the acceleration due to gravity on Earth which is constant having a value of 9.8 m/s^2.

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.
