Answer:

condensation

Explanation:

because water is collected as droplets on a cold surface when humid air gets in contact with it

Condensation is the process occurred when water droplets formed on the grass because water is collected as droplets on a cold surface when humid air gets in contact with it.

The water droplets forming on inside is condensation.The transformation of airborne water vapor into liquid water is known as the condensation of water. It takes place when water transitions from a gaseous state to a liquid or crystallized state.

When the air is cooled below the dew point, the excess water vapor condenses onto surfaces in the form of water droplets. This is why we may notice water droplets forming on the outside of a cold glass of water on a hot day, or on the inside of a window on a cold day.

At high pressure and low temperature, any gas can condense. As a result, water droplets condense on the interior of a chilly windshield. Water droplets can form inside windows due to a process called condensation.

Therefore, Condensation is the process occurred when water droplets formed on the grass because water is collected as droplets on a cold surface when humid air gets in contact with it.

Answer:

I think its B. CO2

Explanation:

Oxygen is only needed for eukaryotes so not A

ATP is the product of prokaryotes

And I highly doubt its salt

ATP is essential to the proper functioning of all prokaryotic and eukaryotic organisms.

For example, biochemical reactions in mitochondria switch power from fatty acids and pyruvate molecules into a power-wealthy molecule referred to as adenosine triphosphate (ATP). Subsequently, the relaxation of the organelles uses this ATP because of the supply of the power they want to operate.

Each organelle helps one-of-a-kind sports inside. Mitochondria, for example, are organelles that offer eukaryotes a maximum in their power with the aid of using generating power-wealthy molecules referred to as ATP. Prokaryotes lack mitochondria and rather produce their ATP on their floor membrane

The feature of ATP synthase is to synthesize ATP from ADP and inorganic phosphate (Pi) withinside the F1 sector. This is viable because of power derived from a gradient of protons which move the internal mitochondrial membrane from the intermembrane area into the matrix via the Fo part of the enzyme.

Hence concluded that ATP is essential to the proper functioning of all prokaryotic and eukaryotic organisms.

Answer:

Gravity is the force that pulls objects towards the earth centre.

Explanation:

According to the postulation of Sir Isaac Newton, explaining Gravity using an apple falling down from a tree. He was so curious to find out why this happened. I hope this helps.

The statement which best describes gravity is that it is the force that pulls objects toward Earth's center. Thus, the correct option for this question is B.

Gravity may be defined as a type of force through which a planet or any other celestial body draws objects toward its center. It is only the force of gravity that specifically keeps all of the planets in orbit around the sun. This force attracts a body toward the center of it.

According to the context of this question, it is a fundamental interaction that causes the mutual attraction between things with mass or energy.

The best example of gravity is understood by throwing a ball high in the air, it will certainly be coming back to the surface of the earth after attaining its maximum height with respect to the energy by which is thrown.

Therefore, the statement which best describes gravity is that it is the force that pulls objects toward Earth's center. Thus, the correct option for this question is B.

Answer:

Explanation:

The main reason why the group's research question is flawed is because it steers more towards ethicality than science. It tries to find where the ethical line is and what "humans" are not willing to do even if it means protecting plants and animals. In order to focus on the scientific aspect the question should instead be rephrased as "How must we go about protecting plants and animals?"

Explanation:

It's called adaptation.

Answer:

normally, insecticides last for over 4 to 5 years before breaking into microbes, the species targeted are destroyed. A should be the answer

Answer:

Adaptations

Explanation:

1). "White" fur- Polar bears are well known for this adaptation, white fur. Their fur is actually clear, but gives the appearance of being white. This is so they can blend into their environment.

2). Fur and fat- They have very thick layers of fur and fat, to help keep them warm(insulate them), as their habitat is extremely cold. This prevents things like hypothermia and frostbite.

3). Large feet- Their feet are quite large, which gives them an advantage. It results in more even, spread out weight distribution, and gives them a better grip on the ice.

Here's an extra:

4). Greasy coat- Polar bears are excellent swimmers, and as a result of their swimming habits, they actually have a greasy coat. This grease is much like oils a duck or goose(or other aquatic aviary species) have. It causes water to roll off of them, meaning they're considered hydrophobic.
