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.

I think its a type of bacteria but im not really sure, is there any choice options?

Explanation:

The dairy business depends on bacteria tiny single-celled organisms because, when added to milk, it consumes milk sugars and produce chemicals that react with the milk to taste and thicken it.

Temperature, pH, water activity, salt-in-moisture levels, and other factors all have a significant impact on how quickly bacteria thrive in dairy goods.

In order to acidify the cheese milk before and during the preparation of dairy foods, starter microorganisms must be used. Streptococcus thermophilus, Lactobacillus sp., and Lactococcus lactis.

However, dairy firms now often standardize the process by adding domesticated bacterial cultures, such as strains of Lactococcus lactis, Streptococcus thermophilus, and Lactobacillus sp. it can be done by naturally existing lactic acid bacteria in the milk.

Therefore, the dairy business depends on bacteria tiny single-celled organisms.

Answer:

The way to figure this this type of question out is card by card. So the first card in the second hand is 2 in 52 (It can match either of the cards in the previous hand). × 1 in 51 ( it has to match the card that was not matched by the first card and there are 51 choises left). So 2 in 52 = 1 in 26 x 1 in 51 = 1 in 26 x 51 = 1 in 1326

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.

Answer:

Early organisms would have to be anaerobic, as air was likely non existent. This rules out the first two options.

Autotrophic can be called producers, and heterotrophic can be called consumers.

The question states that "did not use oxygen for respiration and were unable to make their own food"

Only one option satisfies the question:

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.

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.

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.

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.

Herd immunity is a form of indirect protection from infectious disease that can occur with some diseases when a sufficient percentage of a population has become immune to an infection, whether through vaccination or previous infections, thereby reducing the likelihood of infection for individuals who lack immunity.

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.

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.
