Enzymes increase the rate of chemical reaction by lowering activation energy barriers. Enzymes increase the rate of chemical reaction by providing activation energy to the substrate.
Answer:
B
Explanation:
A deletion of two consecutive base pairs in the coding region of DNA causes a frame-shift mutation. But a deletion of three consecutive base pairs causes the deletion of only one amino acid, with the rest of the polypeptide chain intact. Explain.
The number of deleted nucleotides is critical in determining the extent of damage caused by a deletion mutation in the coding region of DNA.
In the genetic code, amino acid sequences are encoded by a triplet code, with each codon consisting of three nucleotide bases. Each codon specifies a particular amino acid or serves as a stop signal for polypeptide synthesis. As a result, the deletion or addition of nucleotides can disrupt the reading frame of a gene and alter the entire amino acid sequence. This type of mutation is known as a frame-shift mutation.Frameshift mutations that delete or add one or two nucleotides result in significant changes in the amino acid sequence, rendering the resulting polypeptide non-functional or inactive. In contrast, deletions or additions of three nucleotides only result in the loss or gain of a single amino acid. Since amino acids have multiple codons, it is possible that the deleted codon is redundant, allowing the genetic code to still produce the correct amino acid sequence despite the deletion.
The deletion of only one amino acid can have a minor impact on the overall structure and function of the resulting protein, but it is unlikely to be significant. On the other hand, frame-shift mutations that alter the reading frame by one or two nucleotides have a significant impact on the resulting protein, leading to the synthesis of a non-functional polypeptide. Thus, the number of deleted nucleotides is critical in determining the extent of damage caused by a deletion mutation in the coding region of DNA.

Using simple diagrams, compare and contrast the general chemical structures and shapes of each major type of macromolecule. Using specific examples, briefly explain how these structures directly contribute to the main cellular functions of each type of molecule. (Hint: first consider structural and chemical properties of the MONOMERS, and then the polymers.)
The major types of macromolecules, including carbohydrates, lipids, proteins, and nucleic acids, have distinct chemical structures and shapes that contribute to their specific cellular functions.
Carbohydrates are composed of monosaccharides, such as glucose, which can form polymers like starch or glycogen. Carbohydrates serve as a primary source of energy and provide structural support. Their linear or branched structures enable efficient energy storage and quick energy release.
Lipids, including triglycerides and phospholipids, consist of fatty acid monomers. Their nonpolar nature gives them hydrophobic properties. Lipids form structures like cell membranes, acting as barriers and facilitating cell signaling. The structure of lipids allows them to form bilayers, ensuring cellular compartmentalization and selective permeability.
Proteins consist of amino acid monomers, and their chemical structures vary greatly. They fold into intricate three-dimensional shapes, such as alpha helices and beta sheets, driven by hydrogen bonding and other interactions. Proteins have diverse functions, including enzymatic activity, structural support, cell signaling, and transport of molecules. The unique structure of each protein determines its specific function within the cell.
Nucleic acids, such as DNA and RNA, are composed of nucleotide monomers. The double helix structure of DNA provides a stable platform for genetic information storage. RNA molecules have diverse shapes, including single strands and complex secondary structures like hairpins. Nucleic acids are crucial for genetic expression, including DNA replication, transcription, and translation.

A hot air balloon floats in the air while the torch is on. After the fire is
turned off, the temperature of the gas in the balloon decreases. Which of
the following will happen to the gas pressure inside of the balloon?
a) The pressure will increase
b) The pressure will decrease
c) The volume of the gas will increase
d) None of the above will happen
The balloon is raised by hot air rising inside of it. A gas's pressure is directly correlated with its temperature. Consequently, the pressure rises.
What's the volume of a gas?The area occupied by gaseous particles under normal temperature and pressure circumstances is referred to as the volume of gas. It is identified as a "V." The letter "L" stands for "liters," the SI unit of volume. At normal temperature, a mole of gas has a volume of 24 m3, or 24 000 cm3. The molar volume is the amount of space that one mole of any gas takes up at STP (22.4 L). Take note that the second value of the variable is created by multiplying the first value by fractions of the other two variables. EXAMPLE: At STP, a gas sample takes up 125 mL of space.
How do you calculate the volume of gas and how is volume related to gas?For instance, the formula for calculating the volume of 40 moles of a gas at a temperature of 250 K and a pressure of 1013 hPa is: V = nRT/p = 40 * 8.31446261815324 * 250 / 101300 = 0.82 m3.
A contained gas's pressure will rise when its volume is reduced, and fall when its volume is increased. In actuality, the pressure reduces by the same factor as the volume increases, and vice versa.

When a person eats a pieces of chicken, which is filled with protein, it is digested by the body into small nutrients. These small nutrients are then absorbed by cells. The nutrients that came from this piece of meat could be put back together into what kinds of compounds? (has to be at least 2)
Food proteins are digested by enzymatic action. Amino acids are released from these proteins and carried to the consumer's cells where they are used to build new proteins. The nutrients that came from this piece of meat could be put back together into new proteins.
What are proteins and amino acids?
Proteins are polymers with a tridimensional structure needed to accomplish the molecules' functions. These functions depend on the protein, the cell requirements, and the organism that produces them.
Proteins are composed of several amino acids together. These amino acids are monomers.
During protein synthesis, tRNA selects the correct amino acids to build the new protein according to the genetic information provided by mRNA. By working together, mRNA, rRNA, and tRNA arrange amino acids and produce a new protein that will accomplish certain functions.
Some of the amino acids used to build the proteins can not be produced by the organism, so they need to be ingested. These amino acids are introduced to the cell when food is digested and nutrients are absorbed.
The organism breaks down proteins from food into different amino acids that are transported into the cells where they are used.
In the exposed example,
1) the person eats the chicken,
2) the chicken's proteins are digested by enzymatic action,
3) During the chicken's protein digestion, amino acids are released
4) These free amino acids are taken to the person's cells' interior
5) Inside the person's cells, these amino acids are available to be used again by the person's cell.
6) During protein synthesis, tRNA selects the correct amino acids to grow the new polypeptide.

Insects have only innate immunity and lack adaptive immunity. Insects have a large number of circulating hemocytes, which act as a kind of circulating immune cell and play a significant role in clearing pathogens from the body. They also have a broad spectrum of antimicrobial peptides that help fight infection. Insects, on the other hand, lack the B and T cells that are involved in adaptive immunity. Insects are unable to develop immunological memory and are unable to create a secondary response to the same pathogen. They are, however, capable of exhibiting a limited form of immune priming, which allows for a quicker and stronger immune response upon repeated exposure to the same pathogen or a similar pathogen.
Insects, unlike vertebrates, have no dedicated lymphoid organs or tissues. Insect immunity is based on the activity of several circulating blood cells, which operate in a similar way to phagocytic cells in the vertebrate immune system, as well as antimicrobial peptides that act as a kind of natural antibiotic. These peptides may be broken down into different categories, each with its own unique mechanism of action. The lack of a vertebrate-like adaptive immune system in insects does not seem to have had an impact on their survival, as they have been around for more than 400 million years and continue to be highly successful.

The triangular base of a light-refracting prism has a height of 6. 9 mm and a base of 8 mm. If the prism has a volume of 2,760 mm³, what is the height of the prism?
Area of base
B= 27. 6 mm
B= 23. 6 mm
B=20. 7 mm
Height of prism
h= 133. 3 mm
h= 116. 9 mm
h= 100 mm
The height of the prism is approximately 116.9 mm.The height of the prism can be determined by using the formula for the volume of a prism, which is given by V = B * h
Given that the volume of the prism is 2,760 mm³, and the base area is calculated by multiplying the base length and height of the triangular base, we can rearrange the formula to solve for the height:
h = V / B
Substituting the values, we have:
h = 2760 mm³ / (8 mm * 6.9 mm)
h ≈ 116.9 mm
Therefore, the height of the prism is approximately 116.9 mm.
