Based on the Nebular theory, which of these is a step in the formation of the center of a new planetary system?
A. evaporation of condensed gases due to heat
B. combination of condensed gases due to gravity
C. contraction of condensed gases due to nuclear fission
D. expansion of condensed gases due to nuclear fission
Answer:
The answer is the evaporation of water. As the gas begins to collapse, thermonuclear fusion as a result of the immense gravity at the center of the cloud results in the generation of immense heat and radiation that turns solids and liquid into gaseous form, close to the center of the cloud.
Explanation:
This resulted in the nuclear fusion of gases and dust to create the sun and planets at the outer flattened portion of the disk." The sun forms in the center of the cloud since the gravitation effect that drives thermonuclear fusion are strongest in this region. Planets form in the outer regions of the accretion disks where matter attract each other into clumps and gain even more gravitational pull to yank even more matter.
Hope this helps.
Answer:
A: evaporation of condensed gases due to heat.
Explanation:
Here are the 6 steps:
Nebula, protosun forming, spinning planetary disk, protoplanets forming,
Shock waves from a nearby supernova explosion.
It also begins to flatten.
Protosun.
When the gravitational forces begin to fuse hydrogen into helium (fusion)
Protoplanets.
Inner protoplanets - most of their lightweight gases are boiled away
The last step is the answer.

When carbon dioxide is dissolved in the ocean, what can it be turned into?
A. Fossil fuels
B. Seashells
C. Nitrates
D. Zooplankton
I think its B. seashells?
Explanation:
Organisms in the ocean take Carbon Dioxide and turn it into carbonate CO 2/3
Carbonate is often combined with ions like CA 2+ and MG 2+
The Calcium Carbonate makes up the hard structures of corals, and sea shells. The amount of Carbon in the Coral reefs far exceeds the amount of Carbon Dioxide dissolved in the oceans.

Certain individual females in a population of deer decide to stop breeding with males that don't have antlers. this is an example of which Form of speciation
A. Allopatric speciation
B. Sympatric speciation
C. Parasympathetic speciation
Certain individual females in a population of deer decide to stop breeding with males that don't have antlers. This is an example of which Form of speciation A. Allopatric speciation.
What's an allopatric speciation instance?
Allopatric speciation occurs when two companies of organisms are separated by using a bodily or geographic barrier. Not unusual examples of those boundaries include mountain degrees, oceans, or even big rivers. The isthmus of Panama is a high instance of a geographical barrier and it separates the Atlantic and Pacific oceans.
In allopatric speciation, groups from an ancestral populace evolve into separate species due to a period of geographical separation. In sympatric speciation, agencies from the same ancestral populace evolve into separate species with no geographical separation.
Allopatry, which means 'in another area', describes a population or species this is bodily remoted from different comparable companies by an extrinsic barrier to dispersal. From a biogeographic angle, allopatric species or populations are those that do not have overlapping geographic levels.

What is nuclear fission?
O A. The joining of nuclei
B. The gain of nuclear mass
O C. The splitting of a nucleus
O D. The formation of an ion
Explanation:
C is the correct answer i.e. splitting of a nucleus
The splitting of a nucleus is known as the nuclear fission. So option C is correct.
Nuclear fission is the process of splitting an atom’s nucleus into lighter nuclei. This can occur naturally through radioactive decay, or it can be simulated in a laboratory by achieving the necessary conditions (e.g. neutrinos being bombarded). The resulting fragments usually have a mass that is less than that of the original nucleus.
We use the fission reaction in nuclear reactors to create electricity. The heat generated by the fission reaction is converted into a working fluid that passes through a steam turbine. The working fluid then drives a ship's propellers or turns the shafts of electrical generators.

what are the proteins that are found all throughout the cell
Animal cells or plant cells??
Answer:
Explanation:Ribosomes are found in many places around a eukaryotic cell. You might find them floating in the cytosol. Those floating ribosomes make proteins that will be used inside of the cell. Other ribosomes are found on the endoplasmic reticulum.
Earth's early atmosphere was primarily composed of
hyrogen cyanide and carbon monoxide.
oxygen and carbon monoxide.
oxygen and water vapor.
carbon dioxide, water vapor and nitrogen.
Answer:
The correct answer is ''carbon dioxide, water vapor and nitrogen.''
Explanation:
About 4.5 billion years ago, Earth was a very geologically active planet. So many volcanic fumes formed the primitive atmosphere, which was mostly made up of water vapor, carbon dioxide, sulfur, and nitrogen. At this point, oxygen was barely present and the oceans did not yet exist. The primitive atmosphere is the one before the Precambrian, it was reductive, that is, it lacked free oxygen, and only had ammonia, methane and hydrogen, the high temperature of the atmosphere in its early stages facilitated the reaction of these gases to form organic compounds from which life may have emerged. UV rays passed, because ozone did not exist.

How would the Earth's climate change if its obliquity shifted from 23.4° to 0°, and all other factors remained the same?
A-Global warming would increase rapidly.
B-It would shift the Earth into a global ice age.
C-The seasonal changes would be more extreme.
D-There would be no seasons.
Answer:
There would be no seasons.
Explanation:
The tilt of the Earth's axis is what causes seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere. If there was no tilt, the rays hitting the Earth would have minimal changes, meaning no seasons.

A 7th grade teacher asked students to engage in an argument regarding human impact on a national forest ecosystem that was home to mountain lions, coyotes,
and bobcats as well as about 3,000 deer. The deer ate grass, and the mountain lions, coyotes, and bobcats ate deer. Hunters began killing
large numbers of
mountain lions, coyotes, and bobcats. About 20 years later the deer population had increased to about 100,000. The teacher asked the students to explain why
the population of deer increased. Which student's argument most accurately explains the increase in the deer population?
O A. Student 1: The number of deer increased because deer populations are always increasing, even when there are lions, coyotes, and bobcats preying on
them.
O B. Student 2: The number of deer increased because without lions, coyotes, and bobcats, the deer lived longer and had more offspring that also lived
longer.
c. Student 3: The number of deer increased because with fewer mountain lions, coyotes, and bobcats, the deer had more food available to eat
D. Student 4: The deer population increased because with fewer lions, coyotes, and bobcats, there was less competition within the deer population.
Answer:Student 4
Explanation: Because if the mountain lions, coyotes, and bobcats decrease they arent enough to prey on the deer which causes the deer population to be able to reproduce over time.
