What is evaporation?​

Answer:

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.

Answers

Answer:

to study the nature and size of the image formed by a convex lens using a candle and a screen activity file

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.

Answers

Answer:

Predation

Explanation:

A snake that eats a mouse an example of predation.

A snake that eats a mouse is an example of predation. Predation is an ecological interaction where one organism (the predator) kills and eats another organism (the prey). Hence option A is correct.

What is predation?

Predation is an ecological interaction between two organisms in which one organism (the predator) hunts, kills, and eats another organism (the prey). It is a form of consumption where the predator obtains nutrients and energy from the prey, while the prey is typically harmed or killed in the process.

In this case, the snake is the predator and the mouse is the prey. Predation is a natural and common interaction in many ecosystems, and it can have significant effects on population dynamics and community structure.

It can help regulate prey populations, prevent overgrazing, and promote species diversity.

Predators have evolved various adaptations to catch and kill their prey, while prey has evolved various defenses to avoid being eaten, such as camouflage, warning coloration, and physical or behavioral defenses.

Hence option A Predation is correct.

which of these is a source for particulate matter in the air?

Answers

Answer:

Particulate Matter (PM) Sources Components of particulate matter (PM) include finely divided solids or liquids such as dust, fly ash, soot, smoke, aerosols, fumes, mists and condensing vapors that can be suspended in the air for extended periods of time.

Explanation:

Automobiles, dust, and fires are source for particulate matter in the air. Therefore option D is correct.

Particulate matter (PM) refers to tiny particles suspended in the air that can have harmful effects on human health and the environment. Sources of particulate matter in the air include automobiles, dust, and fires.

Automobiles emit exhaust emissions that contain particulate matter, especially from diesel engines. Dust particles can be generated from various sources such as construction sites, unpaved roads, and agricultural activities.

Fires, including both wildfires and controlled burns, release smoke and ash particles into the air. These particles can vary in size and composition.

All of these sources contribute to the presence of particulate matter in the atmosphere, and their emissions can have detrimental effects on air quality and public health if not properly managed or controlled.

Therefore option D all of the above is correct.

Which phrase describes transmutation?(1 point) the conversion of protons to neutrons through nuclear changes the conversion of one substance to another through chemical changes the conversion of an atom of one element into a different element through nuclear changes the conversion of energy to matter through chemical changes

Answers

Answer:

B

Explanation:

PLEASE MARK AS BRAINLIEST!!!!!

Transmutation is conversion of an atom of one element into different element through nuclear changes.

Transmutation consists of the conversion of stable nuclei into other nuclei if they are bombarded by fast particles.

Specifically, an atom can be transmuted by making particles or atoms collide with it at high speed, that is, to accelerate a particle is to increase its speed by some mechanism that imparts energy to it.

Thus, the transmutation of an element requires that there be a change within its nucleus, and in particular in the number of protons.

The neutrons or protons must have enough energy to overcome the nuclear forces that prevent their passage or exit from the nucleus of the atom to be transmuted.

Therefore, we can conclude that transmutation is conversion of an atom of one element into different element through nuclear changes.

which molecule is important in regulating cell membrane fluidity?

Answers

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.
