Lori-an has recently lost a lot of weight. she is now unhealthily skinny. she is concerned by this, and has gone to see her doctor. what diagnosis might her doctor make?

I will try to answer at the best of my ability.

She may have Gastritis.

I hope this helps, and if it is wrong, I am truly sorry.

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
