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.

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.

A student is constructing an explanation of the cycling of matter in and out of a plant during photosynthesis. Which statement would be most useful for the student to include? A.
Photosynthesis uses carbon dioxide and water, and releases oxygen.
B.
Photosynthesis uses oxygen and carbon dioxide, and releases water.
C.
Photosynthesis uses water, and releases carbon dioxide and oxygen.
D.
Photosynthesis uses oxygen, and releases carbon dioxide and water.
The process by which green plants and some other organisms use sunshine to create meals from carbon dioxide and water is called photosynthesis. Therefore, option (A) is correct.
What is photosynthesis?Photosynthesis is the process by which green plants and some other species use sunlight to create food from carbon dioxide and water. Other organisms may also participate in this process. Chlorophyll, a green pigment, is typically involved in the process of photosynthesis, which results in the production of oxygen as a byproduct in plants.
Photosynthesis takes place in the chloroplast, a specialized intracellular organelle found in plants and algae, which emerged considerably later. During the day, photosynthesis is carried out by chloroplasts. The photosynthetic cells use NADPH and ATP, the direct results of photosynthesis, to make a variety of chemical compounds.

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.
