Answer:
Humans directly change the dynamics of the water cycle through dams constructed for water storage, and through water withdrawals for industrial, agricultural, or domestic purposes. Climate change is expected to additionally affect water supply and demand.
Fossil fuel production is another human activity that places considerable strain on drinking water — and not just because fracking and coal mining use a great deal of water, but because their waste products can pollute groundwater, and therefore drinking water, as well.Water resources face a host of serious threats, all caused primarily by human activity. They include pollution, climate change, urban growth, and landscape changes such as deforestation. Each of them has its own specific impact, usually directly on ecosystems and in turn on water resources.

Which statement best describes the roles of photosynthesis and respiration in the carbon cycle?
1 point
A. Respiration and photosynthesis both add carbon to the atmosphere.
B. Respiration and photosynthesis both remove carbon from the atmosphere.
C. Respiration adds carbon to the atmosphere, while photosynthesis removes carbon from the atmosphere.
D. Photosynthesis adds carbon to the atmosphere while respiration removes carbon from the atmosphere.
Answer:
C. Respiration adds carbon to the atmosphere, while photosynthesis removes carbon from the atmosphere.
Explanation:
The answer to this question is c
because respiration adds carbon to the atmosphere but photosynthesis removes that carbon.
Thank you pls give brainiest ! :)
The statement that best describes the roles of photosynthesis and respiration in the carbon cycle is:
Respiration adds carbon to the atmosphere, while photosynthesis removes carbon from the atmosphere.What is the carbon cycle?It comprises a succession of transformations or exchange of matter (specifically carbon-containing compounds) between the biosphere, the pedosphere, the geosphere, the hydrosphere and the Earth's atmosphere.
Characteristics of the carbon cycleThe carbon in CO2 is taken up by plants and released along with water vapor during animal respiration.Respiration and photosynthesis along with other metabolic biotic processes, these processes respectively release and capture carbon dioxide from the atmosphere, as a by-product or input of their biochemical pathways.Therefore, we can conclude that during photosynthesis, plants absorb carbon dioxide from the air and the oxygen not consumed in respiration passes to the atmosphere, being essential in the biogeochemical cycle of carbon.

describe how the bones, muscles, and sensory organs all work together.
The bones, muscles, and sensory organs are grouped to all work together around a common goal: movement.
How the bones, muscles, and sensory organs work together?Sensory organs capture the information, the bones form the skeleton and the muscles that work harmoniously are inserted into the bones through the tendons, allowing the movement of the joints.
They all work together to support the body, keep it in shape and allow it to perform coordinated movements, thanks to the coordination exerted by the nervous system.
Therefore, we can conclude that the bones, muscles, and sensory organs are grouped to all work together around a common goal: movement.

Write an argument for or against the following statement. The energy humans use in cars originally came from the Sun.
Answer in paragraph form using 5-7 complete sentences.
NO LINKS!!!!!!
do the energy humans use in their cars actually originate from the sun? they do! most products like oil, gas, and coal actually come from the sun. the reason why i say this is because all those things are natural which means they came from photosynthesis. according to the site (Where Does the Energy in Fossil Fuels Come From? http://techalive.mtu.edu) "So, in one sense, gasoline-burning cars, coal-burning power plants, and homes heated by natural gas are all solar powered!"
Explanation:
True. All of the energy in coal, gas, and oil was first stored by the sun through photosynthesis. Hence, in a certain sense, solar power is used by gasoline-powered vehicles, coal-fired power plants, and residences heated with natural gas.
What is Energy?In order to accomplish work and to produce heat and light, energy must be transferred to the a body or to a physical system. Energy is the quantitative attribute that does this. Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or destroyed.
Energy is the ability to do tasks. It could exist in several different forms, such as potential, kinetic, thermal, electrical, chemical, radioactive, etc. Moreover, there is heat and work, which is energy being transferred from one object to another. Energy is always assigned based on its nature once it has been transmitted. Hence, heat transmitted may manifest as thermal energy while work performed may result in mechanical energy.
Thus, all of the energy in coal, gas, and oil was first stored by the sun through photosynthesis. Hence, in a certain sense, solar power is used by gasoline-powered vehicles, coal-fired power plants, and residences heated with natural gas.

Do you think an international orbiting space station is a good idea? Why or why not?
Answer:
Yes it is (we already have one)
An international orbiting space station would be a great idea! We could use the space station as a refueling point for passing spaceships. This could helps us achieve things such as space exploration, mars/moon colony, or even contact with other unearthly organisms. This could also allow us to conduct space research.
No it isn't
An international orbiting space station is a horrible idea! The first thing to think about is the money. This would put the entire area in stasis as we try to raise money for the space station. We also need contact with the humans/robots in space! Building a space station would confuse other nations as to what we plan to do with said space station. This could cause a war of some sort.

Answer:
Genotype is the genetic makeup of an individual. Phenotype is the physical appearance of brown hair.
Hello, I Am BrotherEye
Answer:
Genotype is the genetic makeup of an individual eg Bb. Phenotype is the physical appearance eg brown hair.
Explanation:
Your genotype codes for your phenotype — the trait we can actually see. For example, if the blue-eyed parent passed down a blue allele, and the brown-eyed parent passed down a brown allele, the child's genotype will be blue-brown, and his or her phenotype will be brown.
