can someone please write me a essay over *How can human actions seriously affect water resources?*
please please and thank you
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.

Cells in the body take in nutrients and produce wastes. After the wastes leave the cell, what structure do they
enter?
1. Another cell
2. A capillary
3. The digestive system
4. The kidney
5. The lungs
Answer:
The Digestive System
Explanation:
Most nutrient absorption occurs in the small intestine. Nutrients are absorbed through its walls into the circulatory system and by the time the chyme exits the small intestine, only water and undigestible substances are left behind. The chyme then enters the large intestine. (Or The Digestive sytem anways)

If a person has brown hair, what genotypes might they have?
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.

If the "A" represents red flowers and "a" represents green glowers, what are the chances of the flowers being green?
Answer: 50%.
Explanation:
The A allele, which corresponds to red flowers is dominant, meaning if one is present, the flower is red. This generates Aa, which matches 2 squares, denoting a 50% in 4 total boxes. The a allele, corresponds to green flowers but is recessive, meaning both alleles must correspond to said trait to be expressed. 2 squares fit this scenario, making another 50% chance. Therefore, the answer would be 50%.

What percentage of the pea pods are going to be yellow?
Answer:
50% will be the percentage
Explanation:
Since you have two lowercase letters on the right side of the punnet square, there is a 50% chance that the pea pods will be the color green and the other side is dominated by yellow pea pods, which tells us that the percentage is also 50%. Summarized, there is a 50% chance that the pea pods will either be green or yellow.

Organisms are classified into one of three domains by scientists. Which of the following characteristics is used most often to classify organisms into the proper domain?
A. genetic similarities
B. body shape similarities
C. presence or absence of photosynthesis
D. presence or absence of a cell membrane
Answer:
Most likely A. Genetic similarities
Explanation:
Because that is how you can tell they are alike and what they have in common to actually classify what family, kingdom, and domain they are in.
Genetic similarities are used most often to classify organisms into the three domains. Therefore, the correct option is A.
What are the three domains of life?The three domains of life are Bacteria, Archaea, and Eukarya, and they are distinguished based on their genetic differences. For example, Bacteria and Archaea are prokaryotes and lack a nucleus, while Eukarya are eukaryotes and have a nucleus.
The genetic material in Bacteria and Archaea is organized differently from that in Eukarya, and they also have distinct cellular structures and metabolic pathways. Therefore, genetic differences are the primary characteristic used to classify organisms into their appropriate domain. Therefore, the correct option is A.

describe an experiment (using 3-5 complete sentences) that you could conduct to test whether or not humans can see in complete darkness. Make sure to include your independent and dependent variables.
Answer:
An experiment that I could conduct to test whether or not humans can see in complete darkness is by simply going into a place where I know it would be pitch black if I turned off the lights. Such as an basement or closet. I could have a friend or family member place an object close to me in the same room. Once the lights have been shut off I could easily try and find it. I have tried this experiment using a friend and myself. I could find the object just by trying to use things near me to guide myself and eventually found it. My friend on the other thought that they didn't need to use any senses to find the object but failed sadly. I say that my way of working my way to the object in the dark was most helpful because if you are familiar with your surroundings it could make things a lot easier. If you try not to use senses to help yourself in the dark things could get dangerous. You could either run into something or get hurt or end up grabbing the wrong thing.

Optical fibers ____ ___ for very ___ distances by using total internal reflection. The information is encoded as ____. Light waves travel ____ ___. Information sent from New York by fiber optics could reach Australia in less than ___ ____.
The information must be encoded to be sent as patterns of ______.
But Morse code serves as a ____ that we can use to understand ___ ___ is __ and ___ through optical fibers as light waves.
Answer:
In modern communications, such as Internet, cable TV, and telephone communications, information is sent via signals in laser light through clear cables called optical fibers, which are also known as fiber optics. Optical means it has to do with light waves.
The information must be encoded to be sent as patterns of light. One model of how information can be encoded is Morse code. Actual Internet data, cellular phone, and TV signals are not sent by Morse code. But Morse code serves as a model that we can use to understand how information is encoded and sent through optical fibers as light waves.

How does the level of surface water affect the amount of water vapor in the air?
If there’s more surface water then there will be more water vapour in the air if the climate is warm then that will also increase the amount of water vapour.
What is condensation answer?Condensation is the method where water vapour becomes liquid. It is the knock of evaporation, where liquid water becomes a vapour.
the air is cooled to its vapour point or it becomes so soaked with water vapour that it cannot hold any more water.
Thus, the level of surface water affects the amount of water vapour in the air.

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.

If the subject without diabetes eats a high-carb food such as the candy bar or orange smoothie, then the blood glucose levels will (increase/decrease/stay the same) after a three-hour digestion period.
After 3 hours of the digestion period, the blood sugar level will be SAME if the subject is NOT DIABETIC.
Diabetes is a chronic condition of high sugar levels in the blood. Diabetes is of three types - Type 1 and 2
Type 1 - The pancreas is unable to make insulin, required to maintain blood sugar levels. Type 2 - In this type, the pancreas does secrete insulin but that remains insufficient for it to maintain the levels of sugar in the blood. If the subject is suffering from diabetes and eats high card food then his/her sugar levels will increase after 3 hours of digestion.
