How do transitional fossils help explain the evolutionary steps that took place to produce modem organisms?​

Biology

lesya [120]3 years ago

Answer:

Transitional fossils show how a particular taxa accumulated adaptations to fit particular environment​s and/or ecological niches

Explanation:

Transitional fossils are fossilized remains of taxonomic groups/species that illustrate an evolutionary transition between a known version of a taxa/species and the current taxa/species. Transitional fossils are fundamental because they can be clearly differentiated from the ancestral group as well as of its derived descendant group. For example, there exist transitional fossils known as "mammal-like reptiles"(i.e., therapsids that gave rise to the true mammals), which are clearly different from current mammals.

lions [1.4K]

Answer:

Yes, it is possible to get shingles more than once.

Explanation:

Women are more likely to have shingles a second time more than men.

The longer the post herpetic neuralgia ( pain after shingles) the higher the chances of recurrence.

If shingles comes back, it may occur on another side of the body. This is because, once you have had chicken pox, the virus remains in the nerve. When the virus then reactivates the infected nerves become inflamed and when the virus reaches the skin, the rash appears.

Which factors are involved in earthquake formation? Check all that apply. plates moving rocks breaking stress that decreases fau
AfilCa [17]

The correct answers are:

- plates moving;

- breaking rocks;

- movement bellow the surface;

The earthquakes are a direct result of the plate tectonics. In order for an earthquake to appear, there should be a geologic activity caused by the movement of the tectonic plates. The movement of the tectonic plates causes a lot of pressure on the rocks. The rocks eventually break at certain places under the pressure. A they break, there's movement bellow the surface, or rather inside the crust, also referred to as adjustment. That movement and the release of power from it, causes lot of strong vibrations. The vibrations spread out and start shaking the ground in the surrounding area, which is actually the earthquake itself.

Answer:

Some factors that may cause a decrease in population size:

- a high mortality rate due to an infectious disease

- a low birth rate

- a high mortality rate due to interspecific competence  

- a high emigration rate

Explanation:

In biology, population size (N) refers to the total number of individuals in a given population. The four main factors that affect population size are birthrate (natality), death rate, immigration rate (i.e., the number of individuals of a given species that move into a population), and emigration rate (i.e., the number of individuals of a given species that move out of a population). Both birthrate and immigration are known to increase N, while death rate and emigration are rates known to decrease this value.
