Answer: Frequent and inappropriate use of methicillin-type antibiotics has provided selective pressure that has resulted in an increase in the proportion of methicillin-resistant strains of Staphlococcus aureus.

Explanation: The methicillin resistant Staphlococcus aureus is an example of the Theory of Evolution explained by Darwin. He stated that evolution is brought by 3 principles: Variation - the variety of species allows them to adapt better in the environment; Heridity - when those characterists necessary for survival passes on to the next generation; Natural Selection - the organism which is the most adapted to the environment survives to passes on their characteristics;

In a strain of Staphlococcus aureus, there are strains which are resistant to the antibiotics. The constant use of the medicament, and sometimes, the misuse of it, can select those strains which are resistant. As these characteristics are crucial for their survival, they are passed on to the next generation.

This is why the rate of methicillin-resistant Staphlococcus aureus has increased along the years.

photosynthesis

as in the process of photosynthesis plants take in carbon dioxide and give out oxygen.

hope it helps you

please mark me as brainlist

The process of taking gaseous carbon dioxide or oxygen by leaves is termed​ peristomal diffusion or diffusion through stomata present on leaves.

Plants take up carbon dioxide or oxygen from the air through their leaves as they have several stomata on their surface. The small holes or openings in the underside of the leaf are called stomata.

Thus, the correct answer is - peristomal diffusion or diffusion through stomata present on leaves.

Answer:• Apply a strip of masking tape, about 3 inches long, to the outside of each jar. Label each vial in writing on the masking tape with the marker. Write the following labels: hot water, cold water, RT water, vinegar, alcohol.

• Add 1 cup of the appropriate liquid to each of the labeled jars. Wear eye protection when working with vinegar or alcohol.

• Add 2 tablespoons of sugar to the pitcher of cold water. Immediately start the stopwatch and begin to stir slowly until all the brown sugar is dissolved. Record how long the process took.

• Add 2 tablespoons of sugar to the jug of hot water, start the timer and stir the liquid at the same rate as in step 1 until all the brown sugar is dissolved. Write down how long it takes.

• Repeat the process of adding the sugar, stirring, and the time it takes for all the sugar to dissolve for the jugs of room temperature water, alcohol, and vinegar.

• Compare your results. Does sugar dissolve faster or slower from one solvent to another? Does sugar completely dissolve in each solvent? How did the temperature of the water affect the time it took for the sugar to dissolve?

There are fewer organisms at the top of the food chain because there is

less energy available for life processes is the best statement that supports

it.

This is the position an organism occupies in a food chain. The organisms

are usually fewer while those at the bottom have more organisms present

in the chain.

As food chain moves from bottom to the top, the energy level decreases

Because of the x and y chromosomes and they split apart and that's how you get 4 offspring.

The fusion of two different gametes leads to the formation of new offspring is called reproduction. There are two types of reproduction that is sexual and sexual.

The correct option is A

The branch of biology which deals with the study of genes is called genetics. there are two types of alleles that give all the character to the phenotypes. The dominant allele is the allele that suppresses the recessive allele and shows its effect.

In question, the F1 generation shows only one type of character which belongs to parent 1 because that is the dominant allele.

Hence, the correct option is A that is all four offspring received all of their genetic information only from Parent 1 and are therefore identical to that parent

Answer:

C

Explanation:

Answer:

Follows are the explanation to the given points:

Explanation:

The polymerization of αβ-tubulin ligands costumes the microtubules. Among rising or reducing processes a microtubule may oscillate. Part of the carbon is a polar framework for two separate ends: a rapidly growing, most ending as well as a slow-growing less end.

In point a:

Severing a mitochondrial membrane throughout the media will create new "plus ends" or "minus ends." when mentioned in the question Then microtube is more prone to growth at most by adding GTP sub-units to some of the most open regions, where β-tubulin is activated. Even so, for some time GTP has also been hydrolyzed, keeping only one cap of the newly created, higher-end GTP-carrier subunits together with the remaining GDP-carrying cylindrical cap.

Consequently, a positive end is developed that consists of GDP subunits. Because the GDP sub-units become less strictly connected than that of the GTP sub-units, they eventually separate from one another. This allows a microtubule to be polymerized which causes the microtubule will shrink. But the newly exposed microtubule and sides will shrink if cut throughout the center.

In point b:

Well if the equivalent of GTP with such a microtubule is separated by laser from a non-hydrolyzable one, the newly exposed plus finish will include GTP carries. This GTP was NOT supplied with both the GDP kinase but would still expand the mitochondrial membrane. The unburned GTP plus microtubule will therefore continue to grow once it is cut in the center. The GTP equivalent is not hydrolyzable.

H. Haploid

Explanation:

A cell that contains two of each chromosome, or 2n, is a diploid.  If a cell has half of those chromosomes, or just n, it is a haploid.

Answer:

The mRNA leaves the nucleus and travels to the ribosome where proteins are synthesized

Explanation:

During transcription, a messenger RNA (mRNA) molecule is synthesized from a specific DNA region which is referred to as a gene. Subsequently, the mRNA leaves the cell nucleus through the nuclear pores of the nuclear membrane and travels to the ribosome, where this sequence serves as template to synthesize a protein, in a process known as translation. Within the ribosomes, triplets of consecutive RNA nucleotides called codons bind to complementary RNA nucleotides (called anticodons) of the transfer ribonucleic acids (tRNAs). Each tRNA attaches a specific amino acid that corresponds to its anticodon sequence, which is then added to the nascent polypeptide chain.

Seed dispersal can be defined as the process where the movement and spread of seed away from the parent plant by different carrier

Dispersing seeds there is less competition between seeds and The act of seed dispersal includes three phases such as departure, transfer and settlement

There are five different dispersal mechanism such as  wind (anemochory) water (hydrochory), gravity (barochory), ballistic and dispersal done by animals (zoochory).

the most effective method was the zoochory, but today the most effective seed dispersal is the seed dispersal done by humans, because of the big technology boom.
