Explained the effects of the use of antibodies in the control of a disease
Answers
Answer:
An antibody, also known as an immunoglobulin, is a large Y-shaped protein produced by B- cells and used by the immune system to identify and neutralize foreign objects such as bacteria and viruses.
Each tip of the “Y” of an antibody contains a paratope (a structure analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision.
Though the general structure of antibodies is very similar, a small region at the tip of the protein is extremely variable, allowing millions of antibodies with different antigen binding sites to exist. This region is known as the hypervariable region.
Five isotypes of antibodies are found in different locations and perform different specific functions.
The base of the Y plays a role in modulating immune cell activity. This region is called the Fc region, and phagocytes may bind to it to initiate phagocytosis.
Antibodies that bind to surface antigens on a bacterium attract the first component of the complement cascade with their Fc region and initiate activation of the classical complement system.

Which of the following is NOT a place that releases enzymes for digestion?
Answers
as in the mouth the two enzymes in your saliva are called amylase and lipase, and digestive enzymes are mostly produced in the stomach and small intestine.
Answer: D. esophagus
Explanation: Because esophagus uses muscles and does not use enzymes to digest. It only transports food to the stomach and then goes further into the digestive system.
Why not your mouth because it uses the enzyme Amylase, which helps break down complex carbohydrates. It is also produced by the mouth. Lipase, which breaks down fats. Protease is a protein-breaking enzyme that breaks down proteins.
Your stomach also uses enzymes as your intestine.

Which statement correctly describes the flow of energy in photosynthesis?
Answers
Answer:
DPhotosynthesis stores energy because energy is released when glucose is formed from carbon dioxide and water. The passage describes a condition that is inherited.
Energy from the Sun flows into plants through photosynthesis, which is also known as “putting together with light,” and eventually into humankind. In the end, humans are powered by the Sun's energy to eat and survive. Thus, option D is correct.
What describes the flow of energy in photosynthesis?Solar energy is converted into chemical energy during photosynthesis, which produces glucose from water and carbon dioxide. The by-product is the emission of oxygen. In the process of breaking down glucose during cellular respiration, oxygen is consumed, which also produces heat and chemical energy.
Photosynthesis is the tremendous energy flow that underlies electricity and is the foundation of all life. Whether we are vegetarians or not, we joyfully devour our food without giving the basic mechanism that provides us with this gift even the least thought.
Therefore, Because energy is released when glucose is created from carbon dioxide and water, photosynthesis saves energy. The paragraph mentions a hereditary ailment.

Complete question:
Which of the following pairs represent homologous structures?
Wings of grasshopper and forelimbs of flying squirrel Tentacles of Hydra and arms of starfish Forelimbs of a bat and forelegs of a horse Wings of a bird and wings of a mothAnswer:
3. Forelimbs of a bat and forelegs of a horse
Explanation:
Homologous characters are structures with the same basic elements. Their position in the body and the relations with adjacent structures are also the same in different organisms, and they even share the same embryological development.
These structures might show variations between the organisms exhibiting them. Variations might be related to their function and to the environment in which the organism lives. The function they accomplish is not necessarily the same in all the organisms involved.
These homologous characters are present in organisms related that share a common ancestor.
For example, whales, humans, and cats all have the same bones in the same order, but they matured differently in later embryological development.
Among the options, the only possible pair that represents homologous characters is option 3. Forelimbs of a bat and forelegs of a horse. Both structures are the anterior extremities of the animals and share the same bones, even though they might differ in the development degree. Forelimbs and forelegs have the same position and relation with other structures in the body, and embryologically, they are the same.

The products of the glycolysis of one molecule of glucose can drive the citric acid cycle
Answers
Answer:
Since glycolysis of one glucose molecule generates two acetyl CoA molecules, the reactions in the glycolytic pathway and citric acid cycle produce six CO2 molecules, 10 NADH molecules, and two FADH2 molecules per glucose molecule
The products of glycolysis alone are not sufficient to directly drive the citric acid cycle (also known as the Krebs cycle or the tricarboxylic acid cycle).
However, the output of glycolysis, specifically pyruvate, is a crucial substrate that enters the mitochondria, where it undergoes further processing before entering the citric acid cycle.
The energy carriers, specifically NADH and FADH2, play a crucial role in driving the electron transport chain, the final step of cellular respiration.
The electron transport chain uses the energy from NADH and FADH2 to generate a large amount of ATP through oxidative phosphorylation.
Thus, while the products of glycolysis do not directly drive the citric acid cycle, they contribute to the overall energy production and supply the necessary substrates, such as acetyl-CoA, which is essential for the initiation of the citric acid cycle.

Explanation:
Option C above is the correct answer.
Spore formation is actually a method of asexual reproduction. Fungi actually reproduce asexually via spore formation. Some examples of organisms that reproduce via spore formation are Rhizopus, mushroom, mucor, etc.
The spores are usually stored in sacs which are known as sporangia. When there is a bursting of the sac, spores that are single-celled, thick and thin walled are obtained/formed. The spores are usually resistant to environmental conditions.

After many years of normal function, a cell begins producing different proteins than it produced before. Propose two different explanations for this change.
Answers
Answer:
Explanation:
In order to produce different proteins, mutations must occur in the genetic material of the cell. We distinguish gene and chromosome mutations. Mutations in the level of genes are called point mutations because only one to several nucleotides are changed. These processes are known as deletion, insertion, and substitution. Mutations can also appear in chromosomes altering their number and structure. There are four types of mutations: deletion, duplication, inversion, and translocation.
Cells are the functional unit that has a specific activity to perform. The alteration of the cell function can be due to gene or chromosomal mutations.
What are gene and chromosomal mutations?A change in the sequence of the DNA of the gene causes gene mutation and affects the gene or the part of the DNA of the chromosome. They occur in a single place and are called point mutations.
The point mutation is the alteration, addition, deletion or inversion of the single nucleotide base pair of the gene.
The chromosomal mutation affects the whole chromosome and alters the shape and size of the chromosomes. It leads to the increase or the decrease of the ploidy and structural shape.
Chromosomal mutation can be due to translocation, deletion, inversion and duplication of the chromosomes. Their increase or decrease affects the genome as a whole.
Therefore, alteration of the cell can be due to chromosomal or gene mutation.

The Arg genes that encode the enzymes for arginine biosynthesis are located at several positions around the genome of E.coli, and they are regulated coordinately by a transcription regulator encoded by the ArgR gene. The activity of the Arg R protein is modulated by arginine. Upon binding arginine, ArgR alters its conformation, dramatically changing its affinity for the DNA sequences in the promoters of the genes for the arginine biosynthesis. A. Given that ArgR is a repressor protein, would you expect that ArgR would bind more tightly or less tightly to the DNA sequences when arginine is absent?
Answers
Solution :
The Arg genes is used to synthesize the arginine. Arginine is chemical building block. It is very important and is used by our body to make the proteins for our body. When the Arg ID is abundant, the expression for the biosynthetic genes must turned off. And if the ArgR behaves as the gene repressor, then the binding of the arginine increases the infinity for the regulatory sites, and allows it to the bind and then shut off the expression of the genes.
If the ArgR acts as the gene activator, then the binding of the arginine would be predicted to reduce the affinity for the regulatory DNA, and preventing the binding and the shutting off the expression for the Arg genes.

Answer:
Did you ever get the answers?
Explanation:
Any trait that is to be considered as a competitive advantage, trait must allow the individual to survive better and reproduce more in that environment.
What is evolution?
Evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. It is decent with modification from preexisting species.
The trait that has the ability of relative fitness which means relative survival and relative reproduction shall be considered as more competitive. Both of these, criteria possess a competitive advantage.
Hooves are more advantageous for horses in the modern era because hooves are better suited for environments with a wider range of vegetation. Hooves help horses run farther and faster on the open prairies, helping them flee from predators and find fresh grass for grazing.
The species which is most likely to adapt and evolve to this change is an insect species with high reproduction rates and a significant mutation rate. This is because insect belongs to r-selected species that have fewer chances of extinction as compared to k-selection species.
The factor which is driven by random events is Genetic variations.
The factor which is most likely guarantee evolution rather than extinction is higher reproduction rates. Because a higher reproduction rate is a characteristic of r-selected species.
