A star begins to form when a cloud of dust and gas collapses inward as a result of gravitational forces.

true or false​

Answers

Answer 1

Answer:

true- As the cloud collapses, the gravitational force pulling the particles together becomes stronger than the forces holding them apart. This causes the cloud to collapse in on itself, which in turn causes the temperature and pressure in the center of the cloud to increase. These conditions are necessary for star formation.

Answers

Primary succession occurred, followed by several secondary successions.

What are examples of secondary succession?

An example of secondary succession is the development of new inhabitants to replace the previous community of plants and animals that have been disrupted or disturbed by an event (e.g. forest fire, flood, harvesting, epidemic disease, pest attack, etc.). Secondary succession starts when a disturbance (such as wind storms, insect outbreaks, logging, avalanches, bulldozers, or fire) leaves the soil intact. Seeds, spores, and roots usually remain as well. Sites that begin with secondary succession reach the next stage more quickly than during primary succession.

The fertility rate at a specific age is defined as the number of children born alive to women of that age in a given year expressed as a percentage of the average yearly population of women of that age.

A total fertility rate, or TFR, of 2.5 children per woman in 2022 is an example. According to this data point, each woman will have 2.5 children during her reproductive years. This is a predicted fertility rate, not what each woman experiences.

The statement that the hemisphere of the earth that is tilted away from the sun receives less direct rainfall than other hemisphere is false.

What happens to the hemisphere tilted away from the sun?

The hemisphere that is located in the area of the Earth that is tilted away from the sun will receive less direct sunlight because the sun does not have access to it directly.

Rain has to do with atmospheric processes on the Earth which are not as affected by the tilt of the Earth. As a result, direct rainfall can still come to the hemisphere that is tilted away.

Explain the difference between wind ocean currents versus thermohaline currents.

I really need help, please!!!​

Answers

Gravity, wind (Coriolis Effect), and water density all contribute to the continuous, predictable, directed movement of seawater known as ocean currents. Water in the ocean may travel both horizontally and vertically. Vertical shifts are referred to as upwellings or downwellings, while horizontal motions are known as currents. It is effected by temperature but not by the salinity.

The movement of ocean currents caused by variations in temperature and salinity in various water zones is known as thermohaline circulation. Water moves in accordance with changes in density brought on by temperature and salinity.

Typically, the Pacific and Indian Oceans are where this takes place in the tropical ocean. Because it is influenced by changes in temperature (thermo) and salinity (haline), this very vast, sluggish stream is known as the thermohaline circulation.

It is a nonflowering seed plant.

Answers

We can actually deduce here that the based on this description alone, the sentence that is most likely true about this species is: It is vascular.

What is a vascular plant?

A vascular plant is actually known to be a plant that possesses lignified tissues which are used for conducting water and minerals. Those lignified tissues actual transport water and minerals throughout the plant.   Vascular plants also possess specialized non-lignified tissue that actually help to conduct products that are produced during photosynthesis.

We see here that vascular plants include angiosperms, ferns, gymnosperms, and horsetails.

Thus, we see here that as Luna notices that the plant has a woody stem and is about a foot taller than she is, we conclude it is vascular.

Muslims agree with that God had formerly discovered Himself to the sooner prophets of the Jews and Christians, along with Abraham, Moses, and Jesus. Muslims consequently be given the lessons of both the Jewish Torah and the Christian Gospels.

They accept as true with that Islam is the perfection of the religion revealed first to Abraham (who is considered the primary Muslim) and later to different prophets. Muslims consider that Jews and Christians have strayed from God's authentic religion but preserve them in higher esteem than pagans and unbelievers. They name Jews and Christians the "human beings of the e-book" and permit them to practice their own religions. Muslims consider that Muhammad is the "seal of the prophecy," by means of which they mean that he is the final in the collection of prophets God sent to mankind. Muslims abhor the followers of later prophets. This attitude serves to provide an explanation for the acute Muslim animosity towards Bahais, followers of a nineteenth-century prophet, who in the Muslim mind is fake.

Muslims trust that the Qur'an, the holy ebook of Islam, was found out to Muhammad over a period of twenty-three years, starting with the initial revelation at Mount Hira. After the Prophet's dying, his successors compiled those divine revelations in a manuscript.

a. the bathypelagic zone
b. the mesopelagic zone
c. the abyssal zone
d. the epipelagic zone
e. the benthic zone

Answers

Answer: D. The epipelagic zone

Explanation:

The zones of the open ocean are, going downwards:

Epi -> Meso -> Bathy -> Abysso -> Hado.

The benthic zone is just referring to the ocean floor, on both the oceanic and continental shelf, and technically is not a part of the "open ocean" (it does not refer to the water but to the floor itself).

So the zone nearest the top, the epipelagic zone, would receive the most sunlight.
