Earth's constantly absorbs energy from the sun, yet stays at a relatively constant temperature. Explain how
Answer: This could be because of how humans as well as plants use that energy from the sun to create energy, but also because though energy from the sun is always on Earth, it can only provide light and energy to on side of the planet at a time. If energy from the sun were hit the earth from all angles it would increase the surface temperature.

What does Nuclease come from? Like what’s it’s source?
A nuclease (also archaically known as nucleodepolymerase or polynucleotidase) is an enzyme capable of cleaving the phosphodiester bonds between nucleotides of nucleic acids. Nucleases variously effect single and double stranded breaks in their target molecules. In living organisms, they are essential machinery for many aspects of DNA repair. Defects in certain nucleases can cause genetic instability or immunodeficiency.[1] Nucleases are also extensively used in molecular cloning.[2]
Depiction of the restriction enzyme (endonuclease) HindIII cleaving a double-stranded DNA molecule at a valid restriction site (5'–A|AGCTT–3').
There are two primary classifications based on the locus of activity. Exonucleases digest nucleic acids from the ends. Endonucleases act on regions in the middle of target molecules. They are further subcategorized as deoxyribonucleases and ribonucleases. The former acts on DNA, the latter on RNA.[2]

1. Consider the statement: "Sickle cell disease is a(n)
disease."
Which of the following terms could fill in the blank to make the statement true? Write "yes" or "no" next to each
possible response. There may be more than one correct answer.
Genetic
Infectious
Potentially lethal
Inherited
Answer:
Genetic = yes
Infectious = no
Potentially lethal = yes
Inherited = yes
Explanation:
"Sickle Cell Disease" is a blood disorder that is mostly inherited. An example of this is the "Sickle Cell Anemia," which means the body of the person is lacking in red blood cells. In order for an infant to carry such disease, both of his parents must pass the defective gene to him. It is a potentially lethal or deadly disease because if not given remedy, it may lead to several complications such as organ damage, leg ulcers, blindness, etc.
It is not infectious, which means that a person with a Sickle Cell Disease cannot transfer it to another person. It is not likely to spread as well.

In the middle of the night, you are awakened by hunger pains. You proceed to get up and go to the kitchen to have a couple of cookies and a glass of milk. Satisfied you go back to bed content. Explain in detail what tissues, organs, and organ systems are involved in completing that task. Be sure to include how the systems interact. The more detail the better! Start with getting up to get the food and include details on the steps in how the food gets digested.
Explain in detail
Answer:
Mouth, stomach, liver, pancreas and small intestine.
Explanation:
If we eat these foods which have carbohydrates, its digestion starts from the mouth because the saliva present in the mouth mixes with the food and start its digestion. When the food reaches to the stomach, the foods are broken down into micromolecules with the help of enzymes secreted by liver and pancreas. After that the food goes to the small intestine where absorption of nutrients and water also occurs.

what is moisture ?moisture is defined as the presence of liquid in an environment, all liquids, which means water and typically in trace amounts.
The trace amount of water could be in wood, food products, or just about anything, the moisture is used to indicate the presence of water in the air, whereas humidity is more accurate.
the impact of Moisture is significant whereas the high moisture content can cause damage to a building and may even cause health problems for the occupants.
There are already different types of materials that can help in preventing unwanted moisture depending on factors such as water vapor diffusion, airborne water movement, capillary suction, and gravity.

Wind erosion and deposition may form?
a) valleys and alluvial fans
b)beaches and spits
c) sand dunes and loess deposits
d) valley glaciers
Answer: C. sand dunes and loess deposits
Explanation:
Wind erosion is when wind forcefully moves sand particles from one place to another. This can end up forming sand dunes which comes in different shapes.
Also, loess are gotten from silt and clay that are blower by wind and deposited on a large area lawyer of land. Therefore, wind erosion and deposition may form dunes and loess deposits.

what is the complimentary strand of DNA to:AGTTCCGAT
Answer:
AGTTGA
Explanation:
I TOOK THE TEST
DNA is double-stranded and the complementary strand of DNA to AGTTCCGAT is TCAAGGCTA.
What is DNA?DNA stands for deoxyribose nucleic acid. It is a polymer of nucleotides and it presents in all organisms as genetic material. It is a double-stranded molecule, and one strand is complementary to another strand. It functions as hereditary material in almost all organisms and it carries information for the development and functioning of an organism.
It constitutes ribose sugar, phosphate, and nitrogenous bases (purines and pyrimidines). Purines (adenine and guanine) are always complementary to pyrimidines.
Adenine forms double hydrogen bond with thymine, while guanine forms triple hydrogen with cytosine. Therefore, the complementary strand to AGTTCCGAT is TCAAGGCTA.
