Answer:
D. The process through which scientists review one another's work to
validate results and conclusions
Explanation:
Peer Review works on literary findings and not communication.
The process through which scientists review one another's work to validate results and conclusions, is the best definition of peer review. The correct option is D.
What is peer review?The system of peer review is employed to assess the merit of a manuscript prior to it being published.
Independent researchers in the relevant research area evaluate submitted manuscripts for originality, validity, and significance to assist editors in deciding whether to publish a manuscript in their journal.
Peer review is essentially an academic term for quality assurance. Each article that appeared in a peer-reviewed journal was thoroughly reviewed by a panel of experts on the topic of the article.
Peer review is meant to evaluate the validity, quality, and, in some cases, originality of articles submitted for publication. Its ultimate goal is to protect scientific integrity by filtering out invalid or low-quality articles.
Thus, the correct option is D.

Which finding would have disproved Virchow’s hypothesis?
1.) Animalcules are not organisms.
2.) Animals are made of non–cell-based matter.
3.) Plants are made of non–cell-based matter.
4.) Cells can generate from nonliving matter.
Answer:
Virchow was a German scientist whose most important work was in the filed of cellular biology and pathology.His scientific experiments and examinations aimed to disprove the idea of spontaneous generation. This idea is based on an assumption that life can spontaneously appear out of non-living matter. After years of scientific work he concluded that only living cells can produce other cells, or that only life can produce life.Therefore, if it was somehow proven that cells can be generated from non-living matter, that would disprove his findings.

An increase in the volume of forests and phytoplankton would lead to a reduction in free "blank" , which in turn could cause a decrease in carbon dioxide in the atmosphere.
Answer: Carbon dioxide
Explanation:
The forests and phytoplankton are carbon sinks, which absorbs the green house gas carbon dioxide from the atmosphere for photosynthesis. The carbon dioxide from the atmosphere and water are used as reactant in photosynthesis to yield carbohydrates and oxygen as products. Thus the carbon dioxide level in atmosphere decreases. This is necessary for controlling pollution in the environment and reducing the environmental temperature as carbon dioxide can make the environment warm.

Gregory wanted to know what type of food spiders prefer to eat, so he performed two different investigations.
In one investigation, he observed a spider in his backyard every day for thirty days. He wrote down what the spider ate each day.
In another investigation, he placed the same type of spider in an aquarium that recreated a portion of his backyard environment. Each day, for thirty days, Gregory placed four different items in the aquarium—a leaf, a cricket, a fly, and a beetle. Then, he wrote down which item the spider chose to eat first.
Which investigation produced the most reliable results?
A. Neither investigation would produce useful data.
B. The first investigation would produce more reliable results because it only required daily observation.
C. Both investigations have benefits and limitations and should be examined together to get the most reliable result.
D. The second investigation would produce more reliable results because Gregory was able to control the conditions of the experiment.
C. Both investigations have benefits and limitations and should be examined together to get the most reliable result

1. A. What is a compound?
1. B.What is one inorganic compound vital
for chemical reactions in cells? What are four groups
of organic compounds important to living things?
2. A.What three important functions does
water perform in cells?
2. B.Suppose a cell is seriously
deprived of water. How might this lack of water affect
the cell's enzymes? Explain.
3. A.Which of the four types of organic
compounds serve as an energy source for cells?
3. B.Which of the four types of organic
molecules contain the element nitrogen?
3. C.An organic compound contains only the
elements carbon, hydrogen, and oxygen. Could this
compound be a carbohydrate? Could it be a protein?
Explain.
Answer:
1a - A chemical compound is a chemical substance composed of many identical molecules composed of atoms from multiple elements held together through chemical bonds. atoms of the equal element bonded in a molecule do not form a chemical compound, in view that this would require two different elements
1b - Inorganic compounds are critical within the body and responsible for many simple functions. The primary inorganic compounds are water (H2O), bimolecular oxygen (O2), carbon dioxide (CO2), and a few acids , bases, and salts. The body is composed of 60–75% water.
2a - it helps with chemical reactions, cellular form and size and helps the cell regulate temperature.
2b - The chemical reactions vital for life would no longer occur or slow it down.
3a - carbohydrates, lipids, proteins, and nucleic acids
3b - Proteins and nucleic acids
3c - A carbohydrate has only Carbon, Hydrogen, and Oxygen, with the hydrogen and oxygen in the ratio 2:1. A protein is made of amino acids. ... So without nitrogen atoms, the compound cannot be a protein. it can be a carbohydrate, because it contains the elements of a compound. An organic compound contains only the elements carbon, hydrogen and oxygen.

What are codons?A segment of three adjacent nucleotides within a DNA or RNA molecule that, when read, denotes the presence of a certain amino acid. There are particular codons that indicate the beginning or end of the translation process. These particular codons are referred to as start, stop, or termination codons.
There are three codons that are referred to as stop codons because they halt the process of translation. These codons are UAA, UAG, and UGA. An amber codon is what's known as the result of a mutation that takes the form of a stop codon but finishes its work prematurely. • The letter AUG is what's known as a start codon, and it's important because it kicks off the translation process.
There are a total of 64 distinct codons, 61 of which specify amino acids and 3 of which serve as termination signals.
