Answer:

An atom is the smallest unit of a pure substance or element that can exist and still retain the properties of the original substance or element.  Common substances, such as air, water, wood and cloth are mixtures of materials and can be chemically or physically broken down into simpler substances.

Answer:

elements cannot be broken down into a simpler substance.

Explanation:

chemical elements are the simplest of substances.

Answer:

There are 20 different standard L-α-amino acids used by cells for protein construction. Amino acids, as their name indicates, contain both a basic amino group and an acidic carboxyl group. This difunctionality allows the individual amino acids to join in long chains by forming peptide bonds: amide bonds between the -NH2 of one amino acid and the -COOH of another. Sequences with fewer than 50 amino acids are generally referred to as peptides, while the terms, protein and polypeptide, are used for longer sequences. A protein can be made up of one or more polypeptide molecules. The end of the peptide or protein sequence with a free carboxyl group is called the carboxy-terminus or C-terminus. The terms, amino-terminus and N-terminus, describe the end of the sequence with a free α-amino group.

The amino acids differ in structure by the substituent on their side chains. These side chains confer different chemical, physical, and structural properties to the final peptide or protein. The structures of the 20 amino acids commonly found in proteins are shown in Figure 1. Each amino acid has both a one-letter and three-letter abbreviation. These abbreviations are commonly used to simplify the written sequence of a peptide or protein.

Depending on the side-chain substituent, an amino acid can be classified as being acidic, basic or neutral. Although 20 amino acids are required for synthesis of various proteins found in humans, we can synthesize only ten. The remaining 10 are called essential amino acids and must be obtained in the diet.

The amino acid sequence of a protein is encoded in DNA. Proteins are synthesized by a series of steps called transcription (the use of a DNA strand to make a complimentary messenger RNA strand – mRNA) and translation (the mRNA sequence is used as a template to guide the synthesis of the chain of amino acids which make up the protein). Often, post-translational modifications, such as glycosylation or phosphorylation, occur which are necessary for the biological function of the protein. While the amino acid sequence makes up the primary structure of the protein, the chemical/biological properties of the protein are very much dependent on the three-dimensional or tertiary structure.

A change to the PRIMARY structure WILL HAVE the greatest effect on a protein's function.

In conclusion, a change to the PRIMARY structure WILL HAVE the greatest effect on a protein's function.

Answer:

DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using 'T' as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'.

The molecules NADH and FADH₂ will carry the electrons to the electron transport chain.

These electron carrier molecules (NADH and FADH₂) are produced during the breakdown of glucose and other energy-rich molecules in the preceding steps of cellular respiration. They carry the high-energy electrons derived from these molecules to the electron transport chain, which is embedded in the inner mitochondrial membrane in eukaryotic cells.

The electrons passed through the electron transport chain ultimately combine with molecular oxygen to form water, which is the final electron acceptor in the chain.

D. Krebs Cycle

Explanation:

Hope this helped.

The answer to this question is Krebs Cycle.  

Krebs cycle. A series of chemical reactions that occur in most aerobic organisms and are part of the process of aerobic cell metabolism, by which glucose and other molecules are broken down in the presence of oxygen into carbon dioxide and water to release chemical energy in the form of ATP.

Overview of the Krebs or citric acid cycle, which is a series of reactions that takes in acetyl CoA and produces carbon dioxide, NADH, FADH2, and ATP or GTP.

The Krebs cycle itself actually begins when acetyl-CoA combines with a four-carbon molecule called OAA (oxaloacetate). This produces citric acid, which has six carbon atoms. This is why the Krebs cycle is also called the citric acid cycle.May 15, 2020

Answer:

Weight of the soil (500g)

Explanation:

According to this question, some students are conducting an experiment in order to find out which of the different soils used absorb heat the fastest. For the first test, they put 500 grams of SAND in a beaker and put a thermometer in the sand.

In an experiment, the variables that must be kept constant for all the groups is called the CONSTANT OR CONTROLLED VARIABLE. This is done in order not to influence the outcome of the experiment. In this case, the weight (500g) of the soil should be kept the same for all other tests.

This means that for the remaining soil being tested, 500g of each type of soil should be used.

Explanation: The car with the smaller mass will require less force to stop than The car with the larger mass that is it

The car with the smaller mass will require less force to stop than the car with the larger mass.

The law of inertia or Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that form unless it is acted upon by an external force.

This law is called the law of inertia because it depends on mass of the object.

The object with more mass will required more force to be stopped while the object with less mass will require less force to be stopped.

Thus, the car with the smaller mass will require less force to stop than the car with the larger mass.
