Burka [1]

Answer:

Option B) study information related to the Cenozoic era

Explanation:

The complete question is

Scientists discovered that the Eocene time period existed in Earths history around 34 MYA. What do they need to do to determine what time period Eocene belongs to on the geologic time scale?

A) learn what happened during Precambrian time

B) study information related to the Cenozoic era

C) view the timing of events in the Mesozoic era

D) research events that happened during the Paleozoic era

Solution -

The period of Eocene belong to the Cenozoic era. The Cenozoic era is divided into three periods-

a) The Paleogene – Existed between 65.5 to 23.03 million years ago

b) The Neogene - Existed between 23.03 to 2.6 million years ago

c) The Quaternary – Started some 2.6 million years ago and is continuing till present

The Paleogene is subdivided into three epochs –

A) The Paleocene – existed between 65.5 to 55.8 million years ago

B) The Eocene – existed between 55.8 to 33.9 million years ago and

C) The Oligocene – existed between 33.9 to 23.03 million years ago

Hence, studying about Cenozoic era will give information about the Eocene epoch

Hence, option B is correct

State one effect the reintroduction of the

Natali [406]

We can confirm that the reintroduction of the wolf to the ecosystem would most likely cause a decline in the population of coyotes.

<h3>Why would this cause a decline in the population of coyotes?</h3>

The wolf, in most ecosystems, is considered to be the top predator. This means that it will also hunt and consume the coyotes. This alone would cause a decline in the coyote population as they now have an additional predator hunting them. Also, the wolves would be competing with the coyotes for food sources, furthering the impact on the coyote population.

Therefore, we can confirm that the reintroduction of the wolf to the ecosystem would most likely cause a decline in the population of coyotes.

lana66690 [7]

Answer:

Eggs are developed and released by the <em>ovaries.</em>

Sperm is produced by the <em>testes</em>.

Explanation:

Ovaries are the site in females where the production of egg takes place. After the formation of an egg, the egg is transported to the fallopian tube, where it might undergo fertilization if a sperm unites with it.

Sperms are the male reproductive cells which are produced by many animals. The sperms are produced in the testes of males.

The sperm and the egg unite to form a fertilized zygote.

How does Caenorhabditis elegans extract the energy it needs for growth and maintenance?

nika2105 [10]

The worm feeds via a "pumping" action in which it first uptakes the fluid surrounding it. Then, it expels the fluid while trapping any bacteria within it. The bacteria are then digested for energy and nutrients.
