It is assumed that organisms with similar anatomical characteristics have evolved relatively recently and have a common ancestor.
<h3>How does comparing the physical characteristics of different creatures help us understand evolution?</h3>
To comprehend how living things originated, scientists study the anatomy, embryos, and DNA of various species. Homological structures provide proof of evolution. These are features that were passed down from a common ancestor and are shared by related creatures. An further piece of evidence for evolution is offered by similar structures.
<h3>What role does anatomy play in the study of relationships between various types of organisms?</h3>
Comparative anatomy, which compares structural similarities, is one of the strongest types of evidence of creatures to ascertain the links between them throughout evolution. It is assumed that organisms with similar anatomical traits have evolved from ancestors who were reasonably closely connected to one another.

Explanation:
Paper wasps, hornets, and yellowjackets all belong to the same family—the Vespidae—and they all provide extraordinarily important ecological services. Specifically, they help us through pollination, predation, and parasitism. Put simply, without wasps, we would be overrun with insect pests, and we would have no figs—and no Fig Newtons.
Hornets and paper wasps prey on other insects and help keep pest insect populations under control. For instance, paper wasps carry caterpillars and leaf beetle larvae back to their nests to feed their growing young. Hornets provision their nests with all manner of live insects to sate the appetites of their developing larvae. It takes a lot of bugs to feed a hungry brood, and it's through these needs that both hornets and paper wasps provide vital pest control services.
Yellowjackets don't get quite as much credit for being beneficial, although they should. Yellowjackets mostly scavenge dead insects to feed their offspring, meaning they prevent the bodies from piling up—like a cleaning service. Unfortunately, their scavenging habits and love of sugar puts them in close proximity to people, which almost never ends well for the yellowjacket or the person.

Answer:
interferes with release of neural transmitter GABA
Explanation:
Alcohol is a central nervous system depressant, meaning it slows down brain functioning and neural activity. Alcohol does this by enhancing the effects of the neural transmitter GABA
depressants essentially "look" like the neural transmitter and so they go in and block the plasce in the brain between synapses, so when the body tries to release GABA, it appears as if it is already filled in, but in reality it is the alcohol that has filled it. once they start buidling up, they block enough that it impairs brain activity
Question
Scientists observe several strata that are tilted at an angle. What most likely caused the tilting?
A. The strata were deposited at an angle.
B. Fossils were deposited within each stratum.
C. The strata were moved after they were deposited.
D. The strata were deposited in a small area.
Answer:
c) The strata moved after they were deposited
Explanation:
Strata can be defined as a layer or layers of sediments, sand e.t.c. that have been deposited at a particular area or land on the earth surface thereby leading to the formation of sedimentary rocks. Strata possesses distinct features that separates it from other layers in the rock.
Strata in rocks occur in an horizontal form or horizontally. If the strata or layers of the rocks look tilted it is because strata was moved after it was deposited.
