Northern blotting is the least likely to be used in identifying transcription factor binding sites. Therefore, option "B" is correct. Northern blotting is used for the analysis of RNA in the given sample. The samples can be tissue, blood, and serum.

The RNA is purified from the given sample. The sample might contain fragmented RNA which is purified and amplified. The target RNA is separated by using an electric current. The RNA moved through the gel which act like a sieve-like matrix. The movement of the fragments depends on the size of the fragments. Smaller fragments move faster than larger ones in Northern blotting.

Answer:

Examination of vertebrate embryos reveals that during corresponding stages of early development,

the embryos appear to be very similar. For example, all vertebrate embryos pass through stages in

which they have gill pouches. The pouches eventually develop into the gill apparatus in fish; in laterevolving vertebrates that do not have gills, the gill pouches undergo further refinement and develop

into structures associated with the head and neck. Similarly, all early vertebrate embryos have tails,

which persist in some animals but regress during the later stages of development of humans. Thus,  

the individual development of an animal occurs through a series of stages that paint a broad picture

of the evolutionary stages (phylogeny) of the species to which it belongs.

"Ontogeny recapitulates Phylogeny", Haeckel

Explanation:

sure po ito

Examination of vertebrate embryos well-known shows that in corresponding levels of early improvement, the embryos appear very similar.

These scientists claimed that ontogeny recapitulates phylogeny (ORP). This word shows that an organism's improvement will take it thru every one of the personal levels of its evolutionary history, or its phylogeny.

Thus, the man or woman improvement of an animal happens thru a chain of levels that paint an extensive picture of the evolutionary levels (phylogeny) of the species to which it belongs.

Okazaki fragments are associated with the lagging strand that demonstrates discontinuous nucleotide synthesis. These fragments are synthesized in the 5' to 3' direction.

During DNA replication, the lagging strand is synthesized in short, discontinuous fragments known as Okazaki fragments. This is because DNA polymerase can only synthesize DNA in the 5' to 3' direction. On the lagging strand, synthesis occurs in the opposite direction of the replication fork movement, resulting in the need for Okazaki fragments. These fragments are initiated by RNA primers that provide a starting point for DNA synthesis. DNA polymerase then elongates the fragments in the 5' to 3' direction, away from the replication fork. The fragments are eventually joined together by DNA ligase to form a continuous strand.

Explanation:

Primary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals first colonize a barren, lifeless habitat. Species that arrive first in the newly created environment are called pioneer species, and through their interactions they build a simple initial biological community. This community becomes more complex as new species arrive. Primary succession is distinguished from secondary succession, which is the recovery of an existing biological community after a disturbance sets back the community’s ecological structure to an earlier stage.

If biofilm formation is observed on the negative control slide, it could be due to either leaving the slide to incubate for too long (Option A) or using non-sterile slides or filter paper (Option C).

In biofilm experiments, the negative control is expected to show no biofilm formation since it does not contain the target microorganisms or conditions necessary for biofilm growth. If biofilm is observed on the negative control slide, it suggests that something went wrong during the experimental procedure. Option A suggests that the slide was left to incubate for too long, allowing unintended microbial growth and biofilm formation. Option C suggests that non-sterile slides or filter paper were used, introducing microorganisms or contaminants that can form biofilms. Both scenarios result in the presence of biofilms on the negative control slide, indicating a procedural error or contamination issue.

Answer:

Explanation:

For the 1st one with the Cheetah: It would be a long tail because it helps them balance when they turn. Sinch Cheetahs move extremely quickly they need a balance to ensure they don't topple over when they turn, this tail provides this balance.

For the 2nd one with the bear: Thick coats on a bare will help provide warmth whenever they go to hybernate. Thin fur would leave room for freezing and wouldn't be able to help them maintain the proper body temperature.

The 3rd one with the clownfish: A round tail provides a bigger boost when swimming since it is able to push more water. A forked tail would create a gap when they swim so they would have to expend more energy than with a round tail.

The 4th one with the Finch: Since grubs live underground a thinner beak would be able to dig them out and stab them faster. This allows them to reach farther and get more food.

Answer:

The correct answer is - A. phototropic and gravitropic.

Explanation:

A plant seedling grows usually two-direction shoots or stems towards light and roots towards the soil or in the direction of gravity. The movement of the plant toward a specific stimulus or effect parts is called tropism and different parts move in a different direction.

The movement of the roots of the plant is usually towards the direction of soil or gravity and this is called gravitropic. The shoot or stem grows from the seedling towards the direction of light and it is called phototropic.

Answer:

The correct answer would be - Two major types of mutations are deletions and substitutions.

Explanation:

The two major types of mutations are deletion and substitution, other than these there are many more mutations that are categorized under gene mutations and chromosomal mutation.

The deletion mutation takes place in the conditions where the DNA deletes or missed copying the nucleotide in a new  DNA molecule. This type of mutation can occur in one or more nucleotides. Whereas Substitution mutation occurs when there is a wrong nucleotide added to the DNA sequence or substitute with other.

Both could be deleterious and takes place at the nucleotide level. Both mutation depends on the number of nucleotide or the location of the mutation on the gene.

Therefore, the correct answer is 0.7 Relative frequency.

The most serious drawback to using library screening to study genetics is that it can result in the identification of gene fragments that are not in the correct orientation or order.

Library screening is a procedure that allows researchers to isolate clones that express a specific protein or contain a specific gene. A genomic library or a cDNA library may be used for this technique.

The other disadvantages of library screening are given below: Library screening, when compared to PCR, is a relatively time-consuming and labour-intensive process. Library screening's capacity to recover a specific gene is highly dependent on the library's quality, complexity, and redundancy. A library may lack certain sequences that are required to discover the gene of interest.

There may be errors or ambiguities in the data collected by the researchers. In a library, the sequences discovered may not necessarily be the most significant for research purposes.

Answer:

D. 4 times as great

Explanation:

The inertia of an object is the resistance offered by the object to change in its motion or position.

Then concept of inertia is obtained from Newton's first law of motion which states that an object which is not subjected to any net external force will remain its position of rest or constant velocity of motion until some net external force acts on it. The object at rest will then start to move whereas the object moving at constant velocity will experience a change in its speed or direction of motion.

This reluctance to change position is greater, the more massive an object is as well as the higher the speed of motion of the object. Thus, inertia is directly proportional to the mass of the object as well to the velocity of an object in motion.

From Newton's first law, inertia can be calculated as the force to be overcome to mobile an object, i.e. Inertia = F = ma

Where m is mass of object, a = acceleration of the object.

Objects on the earth's surface experience a constant acceleration, g.

Thus for a 1 kg mass, Inertia = 1 × g

For a 4 kg mass, inertia = 4 × g

The inertia of a 4 kg mass is four times as great as a 1 kg mass.

The inertia of a 1-kilogram mass, the inertia of a 4-kilogram mass is - D. 4 times as great

Inertia is the property of matter that resists changes in motion. Mass is the quantitative matter of motion.

Thus, the inertia of a 1-kilogram mass, the inertia of a 4-kilogram mass is - D. 4 times as great.
