Solve the 3 following questions (btw this isn’t biology, my questions are Earth Science)
"Many processes work together to keep Earth's water moving in a cycle. There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration. These occur simultaneously and, except for precipitation, continuously."
"The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration."
"The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. Also, the cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth."

Situation: Students Claire and Don are debating the future security of food production. Claire feels that it is most
important that food producers focus on producing enough food to keep up with the world's ever-growing population by
using innovations like biotechnology. Don feels that food producers should focus primarily on adopting methods that
are environmentally friendly and safe for human and animal health.
Answer:
Both the arguments are valid.
Explanation:
Claire thinks enough food should should be produced for everyone, because the world's population is rapidly increasing. Don thinks the environment should be kept in mind, because our environment is getting ruined every second. Hence, both arguments are valid.

consuming nitrogen is not a cell process... true or false?
Answer: False
Explanation: Most of the nitrogen is "fixed" by bacteria in the soil
Consuming nitrogen is not a cell process. The given statement is false.
What impact on plants due to depletion of nitrates or nitrogen?Nitrate plays a very important role in the ecosystem and due to presence of nitrogen plants grow fastly and produce large size of fruits and flowers.
Nitrate has a common inorganic ion found in the plants that has to be required for the proper growth and development of the plant.Many growers including nitrates in their nutrient regiment just to stimulate plant growth. Plants has acquired much nitrate through root intake from the soil and water present around them.
Hence due to the depletion of nitrogen, plants are getting turning to yellow and this shows that it produces smaller fruit. In modern era farmers has been adding nitrogen containing fertilizers which produce large amount of grains, foods and fruits which is also free from diseases.
Therefore, Consuming nitrogen is not a cell process. The given statement is false.

If you are ever stuck in a lightning storm while in your car, you should remain in your car. This is because the rubber tires do not allow for the heat and electricity of the lightning to pass through the vehicle. What physical property is this?
malleability
conductivity
density
viscosity
Answer:
Conductivity
Explanation:
Conductivity is the property of a material which describes the ease with which that substance permits or conducts heat and electricity through it.
Materials can either be good, poor or non-conductors.
Good conductors are those materials which allow heat and electricity to pass through them easily. Such materials are useful in making electrical wires and heating vessels. Metals are good conductors of heat and electricity.
Some other materials are poor conductors of heat and electricity as they do not allow heat or electricity to pass through them easily. Examples are air and water.
Some other materials are non-conductors as they do not allow heat and electricity to pass through them. These materials are otherwise known as insulators. They are useful in making things such as pot handles, electrical wire insulators, etc. Examples of insulators are plastic, rubber, wood, etc.
Someone in a car during a thunderstorm is safer inside because the rubber tires do not allow for the heat and electricity of the lightning to pass through the vehicle as it is a non-conductor of heat and electricity.

State four ways by which animals living in arid and semi arid areas conserve water
Answer:
Arid or Semi-arid regions are defined as the regions that receive little precipitation.
Four ways by which animals living in arid and semi-arid areas conserve water are as following:
They live in burrows to avoid water leaving their body.Some animals have a thick outer covering which reduces moisture loss, such as Scorpions and wolf spiders.Kidneys of animals in arid or semi-arid regions concentrate urine that helps in less excretion of water.Some animals like Gila monsters and camel have the ability to store water in their body such as in their tails and hump respectively, that can be reabsorbed when needed.Plants capture light energy from
the sun and convert it into what
type of energy?

DNA polymerase and RNA polymerase are enzymes. They belong to the catalyst category.
What type of macromolecule is RNA polymerase and DNA polymerase?
RNA polymerase is an enzyme that creates RNA and catalyzes the initiation and elongation of RNA chains from a DNA template.
RNA is formed by a process known as transcription.
DNA polymerase is a type of enzyme that is responsible for creating new duplicates of DNA, in the form of nucleic acid molecules.
Nucleic acids are polymers, which are big molecules produced up of smaller, repeating units that are chemically related to one another.
Thus, DNA polymerase and RNA DNA polymerase and RNA polymerase are enzymes. They belong to the catalyst category.
