Full question:

How can fossils BEST help paleontologists and biologists classify organisms?

Fossils allow scientists to predict what species will become extinct.

Fossils are useful for reconstructing pedigrees and showing family traits.

Fossils allow scientists to have an idea of the time scale that traits evolved.

Fossils allow scientists to always determine the closest living relative to the fossil.

Option C

Fossils allow scientists to have an idea of the time scale that traits evolved BEST help paleontologists and biologists classify organisms

Explanation:

Paleontology is the subject of the records of life on Earth based on fossils.  Paleontologists practice fossil remains to experience various features of extinct and living organisms. Modern paleontologists have a category of tools that assist them to create, review and explain fossils.

Fossils can also present proof of the evolutionary story of organisms. Darwin recommended that new species emerge. Paleontologists and other scientists found a series, or ordering, of when one species evolved relevant to another.

explanation:

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
