The correct option is "C" which is no competition exists between the species.

Since an ecosystem is formed when the living factors in an area interact with each other and with other non-living factors that surround them.

An ecosystem is formed when the living factors in an area interact with each other and with other non-living factors that surround them.

An ecosystem can be as small as a drop of water and large as an ocean.

Answer: Antibiotics are chemicals which, in low concentrations, can selectively kill or inhibit the growth of most pathogenic bacteria and are not harmful to humans.

Explanation:

Neosporin is a type of antibiotics which is used for the treatment or prevention of mild superficial infections. It consists of three active component, hence the name Triple antibiotic ointment. These active components, their mode of action and side effects include:

--> NEOMYCIN : This is one of the active components of Neosporin which inhibits the protein synthesis of an invading pathogenic bacteria through irreversible binding to the 30 S ribosomal subunit of susceptible bacteria. Their MODE OF ACTION is bactericidal meaning that the effect it has on the protein synthesis inhibits it's growth leading to the death of the bacteria.

SIDE EFFECTS: it can cause irritation, burning, itching, rash redness when applied topically.

--> POLYMYXIN: This is one of the active components of neosporin which attacks the invading pathogenic gram negative bacteria. In its mode of action, is the ability to combine with and disorganise structures of the bacterial cell which are responsible for the maintenance of the osmotic equilibrium of the cell thereby exposing the underlying peptidoglycan layer to lysozyme.

SIDE EFFECTS: Burning, redness, or irritation of the skin may occur.

--> BACITRACIN: This is also one of the active components of Neosporin. In its mode of action, it inhibits bacterial cell wall synthesis. This is achieved by preventing the final dephosphorylation step in the phospholipid carrier cycle, which interferes with the mucopeptide transfer to the growing cell wall.

SIDE EFFECTS: it may cause rash, itching/swelling (especially of the face/tongue/throat).

These three active components of Neosporin are combined to broaden the antibacterial spectrum. This means that at least one of the active components will effectively kill an invading pathogenic bacteria through its unique mode of action.

The correct answer would be - 50%.

Explanation:

Hemophilia is a sex-linked recessive disorder that takes place in males more than in females as females have two X chromosomes so if one is affected other still able to make clotting factors but in males, there are only one x chromosome.

If a hemophilic man XhY marries with a carrier women XHXh then the chances of their son for normal blooding would be :

Gametes:

Male: Xh and Y

Female: XH and Xh

Then cross:

             Xh                          Y

XH      XHXh                     XHY

    (carrier daughter)      (normal son)

Xh        XhXh                    XhY

 (hemophilic daughter)  (hemophilic son)

Thus, the chances of normal son is 50% among sons

Explanation:

1)This number is abbreviated as 2n where n stands for the number of chromosomes. For humans, the diploid chromosome number equation is 2n = 46 because humans have two sets of 23 chromosomes (22 sets of two autosomal or non-sex chromosomes and one set of two sex chromosomes).

2)Under normal conditions, the haploid number is exactly half the total number of chromosomes present in the organism's somatic cells. For diploid organisms, the monoploid number and haploid number are equal; in humans, both are equal to 23.

The diploid number is 2n no. of chromosomes and thus it is diploid instead of haploid.

Chromosomes are thread-like systems placed in the nucleus of animal and plant cells. Each chromosome is made from protein and a single molecule of deoxyribonucleic acid (DNA).

Thus it is clear that the diploid and haploid number of the species depends on the number of chromosomes.

Answer:

The highlighted structure is a tract that connects the hypothalamus and epithalamus .

Explanation:

The given highlighted structure is a optic chisma or optic chiasma.

OPTIC CHISMA- The optic chiasm is an X-shaped structure created in the brain by the crossing of optic nerves. The brain and the eye are connected by the optic nerve. The optic chiasm is considered to be a pivotal point of evolution by biologists. The crossing and uncrossing optic nerve fibers that pass through the optic chiasm are thought to have evolved to help with binocular vision and eye-hand coordination.

Nerve fibers from half of each eye pass over to the opposite side of the brain at the optic chiasm. The fibers from the other half of the retina migrate to the same side of the brain as the fibers from the other half of the retina. Every half of the brain receives visual signals from both eyes' visual fields as a result of this junction.    

Hence , the correct answer is hypothalamus and epithalamus .

Answer:

The phenotypic ratio is 7:4:5

Explanation:

To discover the phenotypic ratio between the aaBb and Aabb crossing, it is necessary to fill the Punnet Square for dihybrid crosses, which has 16 houses. Dihybrid crosses are those that present a genetic inheritance confirmed by two characteristics, as is case of the mouse coat shown above. In this case, instead of two alleles per characteristic, we will have four alleles.

The Punnet Square for the crossing AaBb x AaBb, is shown in the image shown below. To form the first row and the first column of the square, we must determine the pair of alleles that each parent has. These pairs are formed by the first "A" with the first "B," the first "A" with the second "B," the second "A" with the first "B" and the second "A" with the second "B" . " For example, in parent AaBb we will form pairs of alleles AB, Ab, aB and ab. We will do this with the two parents. Then we combine the pairs to form the offspring, as shown in the figure.

In order to determine the phenotypic ratio of the offspring, we must pay attention to the information presented in the question. The question states that the Agouti genotype is determined by the presence of the Allelo B (uppercase), for this reason, we must count all the members of the offspring that have at least 1 letter B (uppercase) in their genotype. At the end of the count, you will notice that there are 7 individuals of the offspring with agouti fur.

The black coat is determined by the presence of allele A (uppercase) and absence of allele B (uppercase). In this case, we must count all the individuals who have the Allele A and have the allele b (lower case) in place of B. Upon finishing the count we will notice that there are 4 individuals with the black coat.

The white coat is only seen in individuals who have the aabb alleles, since this color is the recessive characteristic. In this case, we must count all individuals who have this genotype. At the end of the count, we will notice that there are 5 individuals with white coats.

In this case, the phenotypic ratio refers to the number of individuals of each color that is 7: 4: 5.

Explanation: The steps of Cas9 DNA recognition and cleavage goes in the following order lettered A, B, D, C, E and F. Cas9 recognizes and binds the sgRNA after which it binds to the double stranded DNA. It then unwinds and scans the dsDNA for its protospacer adjacent motif sequence (PAM) and on recognition the sgRNA binds to its complementary sequence followed by cleavage of the DNA at two points. That is how the double stranded break is created.

All of the world's plants, animals, and microorganisms are included in taxonomy, which is the science of naming, describing, and classifying species.

Taxonomists identify, describe, and classify species, particularly those that are novel to science, using morphological, behavioral, genetic, and biochemical observations.

Taxonomy recognizes and catalogs the elements of biological diversity, offering the fundamental information necessary for the management and application of the Convention on Biological Diversity.

Taxonomists have identified roughly 1.78 million species of animals, plants, and microorganisms throughout the past 250 years of study, but the true number of species is unknown and likely between 5 and 30 million.

Therefore, All of the world's plants, animals, and microorganisms are included in taxonomy, which is the science of naming, describing, and classifying species.
