The statement that describes nuclear fission is as follows:
Starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms.Thus, the correct option for this question is D.
What is Nuclear fission?Nuclear fission may be defined as a type of nuclear reaction during which the nucleus of an atom splits into two or more smaller nuclei due to the impact of another particle with the liberation of a very large amount of energy.
Nuclear fission is a process where a heavy nucleus is bombarded through neutrons and due to this, it becomes unstable. This causes it to decompose into two or more nuclei spontaneously with equivalent size and magnitude. It involves a tremendous detachment of energy as well as the emission of two or more neutrons.
Therefore, the statement "starts when neutron slams into an atom, causing the larger atom to split into two smaller atoms" describes the process of nuclear fission. Thus, the correct option for this question is D.

select the cell cycle impairments that you predict would lead to cancer. recall that cancer arises from unregulated, repeated cell divisions. choose all that apply.
Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.
Genetic mutations can occur during the life of a cell due to outside factors such as:
The food we eatThe environment we expose the cell toThe substances that touch the cell (e.g skin cells)That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of programmed cell death.
Programmed cell death is what tells a cell when it should stop growing and dividing. This is a regulatory function designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The accumulation of these cells is referred to as cancer.

coevolution
mimicry
environmental resistance
commensalism
ecological succession
The newts have become more poisonous over time, as a result, leading to a kind of evolutionary arms race. This is an example of coevolution.
Coevolution is the process of evolutionary change that occurs between pairs or group of species as they interact with one another.
The predator-prey relationship is the most common type of coevolution. This involves the prey evolving so as to avoid capture and thus leading to the evolution of the predator so as to become more effective hunters.
Predator-prey coevolution is a kind of evolutionary arms race.

which molecule is important in regulating cell membrane fluidity?
Answer:
cholesterol plays a distinct role in determining membrane fluidity.
Cholesterol has a specific impact on how fluid a membrane is. With their polar hydroxyl groups adjacent to the hydrophilic head groups of the phospholipids, cholesterol molecules enter the bilayer.
How does cholesterol regulate cell membrane fluidity?The phospholipid bilayer's random distribution of cholesterol molecules aids the bilayer's ability to remain fluid under a variety of environmental conditions.
Cells control membrane fluidity by modifying the lipid composition of the membrane. A lipid bilayer's fluidity fluctuates according to temperature. Lipid bilayers become more fluid, porous, or leaky at increasing temperatures (like butter melting on a hot day).
Cholesterol makes the cell membrane less fluid at higher temperatures and more fluid at lower temperatures.
Therefore, cholesterol is the chemical in the plasma membrane that has an impact on the fluidity of the membrane.

What is evaporation?

When liquid turns into vapor
Explanation:
hope this helps <33
have a nice day
mark as brainliest plz? :)
A liquid turning into a gas is evaporation. It is how water gets from the surface of the Earth to the atmosphere.
Temperature, surface area, wind speed, and humidity affect a liquid's evaporation rate.
Latent heat is a form of energy held in the evaporated water when it evaporates and cools.
Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.
