Answer:

<h3>Mandible bone</h3>

Explanation:

The nasal cavity externally opens through the nostrils, continues to the pharynx, where, further joins the remaining respiratory system. In the middle, it is separated by the nasal septum. The division of nostrils includes roof, floor, and walls whereas the nasal cavity is divided into the

a) vestibule - It is the dilated area at the nostril opening

b) respiratory - It is the passages through which air travels into the respiratory system

c) olfactory sections- It has olfactory receptors & Bowman's glands.

Surrounding structures:-

a) Para-nasal sinuses

b) Nasolacrimal ducts

c) Oral cavity

Studentka2010 [4]

The answers are as follows:
1. <span>An inhibitor has a structure that is so similar to the substrate that it can bond to the enzyme just like the substrate: t</span>his is called competitive inhibitor. A competitive inhibitor will compete with the substrate for the active site of the enzyme and bind to the active site, thus incapacitating the substrate from binding to the active site.
2. An inhibitor binds to a site on the enzyme that is not the active site: this is called non competitive inhibitors. Non competitive inhibitors bind to other site in the enzyme which is not the active site of the enzyme. The binding of the inhibitor changes the conformation of the enzyme as well as the active site, thus making it impossible for the substrate to bind to the enzyme effectively.
3. <span>usually, a(n) inhibitor forms a covalent bond with an amino acid side group within the active site, which prevents the substrate from entering the active site or prevents catalytic activity: this is called irreversible or permanent inhibition. Permanent inhibitors form covalent bonds with the enzyme and prevent substrate from binding to the enzyme.
4. T</span><span>he competitive inhibitor competes with the substrate for the ACTIVE SITE on the enzyme: The active site of an enzyme is the place where the substrate normally bind in order to activate a enzyme. Competitive inhibitors are those inhibitors that compete with the substrate for the active site of the enzyme and prevent the substrate from binding there.
5. W</span><span>hen the noncompetitive inhibitor is bonded to the enzyme, the shape of the ENZYME is distorted. The non competitive inhibitors are those inhibitors that bind to other places in the enzyme instead of the active site. The binding of the non competitive inhibitor usually distort the shape and the conformation of the enzyme thus preventing the substrate from binding to it effectively.
6. E</span><span>nzyme inhibitors disrupt normal interactions between an enzyme and its SUBSTRATE. The principal function of enzyme inhibitor is to prevent the substrate from binding to the appropriate enzyme. This is usually done in the human system in order to regulate the activities of enzymes.</span>

Answer:

The first blank can be filled with tagging. One of the procedures for studying the movements, biology, and migration of animals is known as tagging of animals. Tagging is utilized to examine the long-range irregular and regular movements of animals and to identify their life-span. All kinds of mollusks, vertebrates, and insects can be tagged.

The second blank can be filled with designate their area as a national park. Designation of the areas as a national park is one of the methods of conserving animals, like a tiger.

Rosa drew a diagram to compare substitution mutations and insertion mutations.

djverab [1.8K]

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

$\huge\boxed{Option A}$

<h2>_____________________________________</h2><h2>Mutations:</h2>

Mutations are the changes produced in the nucleotide sequence of the genome.

There are four main types of mutations

Substitution

Insertion

Deletion

Duplication.

<h2>_____________________________________</h2><h3>DELETION:</h3>

A small segment of chromosome mat be missing. This condition is known as deletion.

For example, Normal chromosome has A B C D E F G. If deletion mutation occurs then mutated chromosome has A D E F G and B C got deleted.

<h2>_____________________________________</h2><h3>DUPLICATION:</h3>

In this condition, a part of chromosome present in exec ess to the normal chromosome.

For example, Normal Chromosome has A B C D E F G. If duplication mutation occurs, then mutated chromosome had A B C B C D E F G and B C is duplicated.

<h2>_____________________________________</h2><h3>SUBSTITUTION MUTATION:</h3>

Substitution is a type of mutation where one base pair is replaced by a different base pair.

For example, in the sequence CAAGT, if C replaces G, it is a substitution mutation.

<h3>INSERTION MUTATION:</h3>

In genetics, an insertion is the addition of one or more nucleotide base pairs into a DNA sequence.

For example, in the sequence CAAGT, if extra base G gets inserted after C, the new sequence would be CGAAGT.

Both substitution and insertion mutations change the position of nucleotide thus, the type of amino acid.

Gel analysis of fragments in step 6 shows that even though the undigested DNA and DNA digested with HindIII are both 1000 bp, th

Soloha48 [4]

Answer:

Size of the band varied

Explanation:

In the given question, the options are not provided but based on the information provided in the question, it can be predicted.

When the DNA was digested by the HindIII, then the length of the digest came about 1000 bp and the undigested DNA was also found 1000 bp.

When both the bands were analysed by Gel electrophoresis then the bands do not run to the same distance therefore this shows that the size of both the bands was not equal and their size varied.

Thus, the size of the band varied is correct.
