Answer:
The categories of patterns of evolution are: <em>genetics/molecular biology, direct observation of evolutionary change, the fossil record, homology/anatomy, and biogeography</em>
Explanation:
- <u>Anatomy.</u> Also known as Homology, is the study of homologous structures of species with similar physical features, as proof of direct descent and ancestry.
- <u>Molecular biology and Genetics</u>. DNA and the genetic code reflects the shared ancestry of life, indicative of how species are related.
- <u>Fossil Records.</u> Fossils register the existence of pre-existing species which are related to present-day species.
- <u>Biogeography</u>. The geographic distribution of organisms on Earth, as well as their distinct features is an indicator of evolution and geological change.
- <u>Direct observation. </u>Organisms with short lifespan can be observed as evolutionary cases.
The possible answers are
<span>A.a drought reduces the toad population </span>
<span>B. an influx of soil nutrients results in increased grass growth </span>
C.a hawk species moves in that hunts toads
<span>D.the toad population increases after a warm, wet spring
The correct answer is D
The increase in numbers in the toad population after a warm and wet spring would mean that there are more toads that prey on the beetles and that they are limiting the beetle population by hunting them.</span>
I don't think so. All a dichotomous key is is a key to different types of species/animals.
That bridge is called "pilus" provided by F+ bacteria.
Answer:
Yes ,corals depend on the zooxanthellae (algae) that grow inside of them for oxygen and other things, and since these algae needs sunlight to survive, corals also need sunlight to survive.
