3 points Over time, if a trait consistently makes an animal/plant LESS fit to survive
it's environment, what will happen?*
The species will have to migrate to another environment where that trait may increase
it's fitness.
Those individuals that have that trait will not survive and not reproduce. Gradually that
trait will become less frequent in the population until it eventually gets removed.
The trait will slowly mutate into a trait that is advantageous for the organism.
O
Some individuals with the trait will survive and others will not. The trait will remain as
long as some individuals survive with it.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

the answer is c.mitochondria. glad to .

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
