Explanation:
The body differentiate between potential pathogen and the body’s cells by chemical markers on the outside of cells that identify them as self and non-self. Thus, option A is correct.
What precautions must be taken during the blood borne Pathogens?
The precautions that must be taken the blood borne Pathogens and Other Potentially Infectious Materials are mentioned below:
Some blood borne pathogens are hepatitis B virus, bacteria and some pathogens as well.The finger or the area must be rubbed with the alcohol and must be involved in the daily routine of the hand hygiene.The area that are exposed with the pathogens must be washed with the water and soap. The exposure source must be notified to the lab assistant or supervisor.The individual should not eat or apply anything on the wounded area exposed with the pathogens.The unprotected sex must be avoided to prevent the transmission of the pathogen from mother to the fetus.The potential for the exposure to blood borne pathogens has not present in the almost all workplaces. This danger occurs more than anything in health workers where they have a high risk of coming into contact with body fluids, including blood, of patients with pathology transmitted by this means that it is not valid to be in other types of work, since they would not be part of its risk matrix.

Answers
Answer:
b. Antibodies are used for Northern blot analysis.
c. VNTRs are highly conserved in human populations.
Explanation:
The northern blot technique is used in molecular biology laboratories for detecting specific RNA molecules in a sample of RNA derived from a particular cell/tissue. Antibodies can be detected by the enzyme-linked immunosorbent assay (ELISA). In ELISA, antigens are used to detect specific antibodies: the addition of the antigen produces a positive reaction i.e., formation of the antigen-antibody binding complex. Subsequently, a second antibody with a particular marker is added to bind with the complex, thereby producing a change in the color and thus evidencing the presence of the target antibody in the sample. On the other hand, the variable number of tandem repeats (VNTR) are short sequences (around 20 to 100 bp) whose number of repetitions varies at specific loci in the genome of many organisms, including humans. Since VNTR sequences exhibit variation in length between individuals of the same species/population, they are widely used as molecular markers to identify individuals, QTL (quantitative trait loci) mapping, establish phylogenetic relationships among individuals/cultivars/lines, etc.

If mutated DNA Sequence #1 occurred in a single cell on the membrane of a fish, how might it impact the organism?
Answers
Answer and Explanation:
This would cause defective proteins to be created in the body that would not form the fish membrane correctly and promote problems with the control and functioning of that membrane. This could harm the organism in many activities, limit its life expectancy, cause discomfort and cause a strain that presents the same problem, since these flaws can be inherited genetically.
A mutated DNA sequence is a DNA molecule that has nucleotides in the wrong order, which causes a mutation and does not allow the correct formation of proteins.

Answers
Answer:
Nucleus
DNA replication happens in the nucleus of human cells. It will also take place within mitochondrial matrix.
Explanation:
DNA replication occurs during the S-stage of interphase. DNA replication (DNA amplification) can also be performed in vitro (artificially, outside a cell). DNA polymerases isolated from cells and artificial DNA primers can be used to start DNA synthesis at known sequences in a template DNA molecule.
About:
In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the most essential part for biological inheritance.
DNA replication takes place in the nucleus of the cell. Thus, the correct option for this question is A.
What is DNA replication?DNA replication may be defined as the process through which the genomic DNA successfully gets copied into cells during the mechanism of cell division. It is a process of creating two identical replicas of DNA from one original DNA molecule.
According to the context of this question, the process of DNA replication takes place during the S-phase of interphase. During this phase, the amont of genetic content doubles in the cell which is then separated into daughter cells equally followed by cytokinesis.
Therefore, DNA replication takes place in the nucleus of the cell. Thus, the correct option for this question is A.

What is a similarity between wind and water?
A) They are both types of non-renewable resources.
B) They are both sources of power for objects that people use.
C) They can both be polluted by pesticides and fertilizers.
D) They are both sources of oxygen for plants and animals.
Answers
Answer:
Hey i think its A :) have a wonderful day !
Explanation:
because they both transfer soil to new places.
Wind is a type of dry deposition method. If original soil is erodable and wind exists, soil particles move via wind (sometimes it is called dust transport) and finally are deposited at final destination regions/areas.
However, water erosion occurs when rainfall or hail occurs. Along with water some soil particles (mostly finer ones) are carried away. Finally close to river mouths (delta regions) or wherever deposition is occurring (within a river canal) these soil particles are deposited.
A) They are both types of non-renewable resources: This statement is incorrect. While there are some forms of energy that are derived from non-renewable sources such as fossil fuels, wind and water are both examples of renewable resources.
How is wind generated ?Wind is generated by the movement of air caused by differences in temperature and pressure, and water is driven by the water cycle, which is powered by the sun. Both wind and water are replenished naturally, making them sustainable sources of energy.
B) They are both sources of power for objects that people use: This statement is correct. Wind and water have both been used for centuries as sources of power to perform work. Wind has been used to power windmills for grinding grain and pumping water, while water has been used to power water wheels for milling grain, sawing wood, and generating electricity.
Today, wind turbines and hydropower plants are common examples of objects that harness the power of wind and water to generate electricity.
C) They can both be polluted by pesticides and fertilizers: This statement is partially correct. While water can certainly be polluted by pesticides and fertilizers, wind is not typically subject to the same kind of pollution. However, it is important to note that wind can carry pollutants and particulate matter, which can impact air quality and human health.
They are both sources of oxygen for plants and animals: This statement is incorrect. While water is an essential component of photosynthesis, the process by which plants produce oxygen, wind is not a direct source of oxygen.
However, wind can play an important role in the dispersal of plant seeds, which helps to facilitate plant growth and regeneration.

Answers
Answer: E. Turgor
Explanation: can i help u with more?
Turgor pressure gives the non-woody plants their shape. Thus, the correct option is E.
What is Turgor pressure?Turgor pressure is the force which is present within the cell that pushes the plasma membrane against the cell wall. It is also called as hydrostatic pressure, and also defined as the pressure in a fluid which is measured at a certain point within itself when the fluid is at equilibrium.
Generally, the turgor pressure is caused by the osmotic flow of water and occurs in the plants, fungi, and bacteria which contain cell wall. The phenomenon is also observed in the protists which have cell walls. This system is not seen in the animal cells, due to the absence of a cell wall in the cell which would cause the cell to lyse when placed under too much pressure condition.
Therefore, the correct option is E.

What is herd immunity, and why are vaccines important for achieving herd immunity?
