Answer:

Deserts

Explanation: Deserts need little to no water

Answer:

All energy on Earth originally comes from the Sun. Plants use sunlight in a process called photosynthesis, to make their own food and provide energy.  This is why plants are producers, because they make their own food. Cows eat plants, namely grass. So, when the cow eats the grass, the energy from the grass transfers to the cow. This is why cows are consumers, because instead of making their own food, cows, like humans, must consume their food to survive.

Improving sanitation would be the most practical way to prevent the spread of cholera in a human population.

The cholera bacteria are passed through feces (poop). It is spread by eating or drinking food or water contaminated by the feces (poop) of an infected person. This occurs more often in underdeveloped countries lacking proper water supplies and sewage disposal.

Cholera is a diarrheal disease caused by the bacterium Vibrio cholera. It is almost always transmitted by water or food that has been contaminated by human waste.

Answer:

their legs contain specialized hairs that are able to repel the water and to capture the air

Explanation:

The water strider is one of the most common aquatic insects. Water striders can sit on the water surface due to they have specialized hydrophobic water-repelling hairs in their legs that allow them to use the surface tension of water in order to distribute the weight. Thus, the hairs in the legs of these insects enable them to float and move on the water surface.

Answer:

its c) condensation and evaporation

Explanation:

Evaporation and transpiration are the two processes that allow water to enter the atmosphere. The correct option is A.

Transpiration is the method by which water vapor is lost via the stomata of plants. When the weather is very hot, the plant's loss of water vapor cools it down, and water from the stem and roots moves upwards or is started to pull into the leaves.

The direct impact of transpiration is that it regulates plant temperature and provides water for photosynthesis. It also transports nutrients and sugars through the plant's vascular tissues.

Evaporation is a way of vaporization that occurs on the surface of a liquid as it transitions from the liquid phase to the gas phase.

Both of these process aids to enter water into the atmosphere.

Thus, the correct option is A.

Cells without lysosomal enzymes will not be able to digest food and these will lead to accumulation of wastes in the cells, leading to cancerous growth and the cells will not be able to live long.

Explanation:

Lysosomes is a membrane bound organelles found in eukaryotic cells that produce lysosomal enzymes which help to breakdown or engulfs biomolecules like proteins, carbohydrates, nucleic acids, lipids it engulfs in the cells to molecules it will easily be absorbed.

Without these enzymes or defect in these enzymes, biomolecules will not be broken down and it's resultant effect is accumulation of wastes which can lead to cells destruction.

Gravitational pull and the earth on its axis

Explanation:

Hope this helps

Gravitational pull and the earth on its axis keeps earth from flying outward into space from its present position.

A gravitational force is defined as  an attractive force which is exerted by a massive body on the massive body. So our body always  tries to pull other body towards itself due to this gravitational force.

gravitational force is a force  exerted by earth on other objects  and can be represented as   F=mg

F is the force of gravity, G is the gravitational constant of the universe and it is always the same number, M is the mass of one object, m is the mass of the other object (measured in kilograms, kg), r can be the distance those objects are apart (measured in meters, m)

This force can also be called as Newton's Universal Law of Gravitation And the object that are really far apart from each other don't pull on each other noticeably either.
