Answer:

their shape, which relates to the lock-and-key model

Explanation:

Enzymes are biological catalysts that are proteinous in nature. Their proteinous nature implies that they are made of amino acids, which forms a three-dimensional shape that accounts for their functionality and specificity. This means that enzymes are substrate-specific because of their 3D shape.

The three-dimensional shape of an enzyme determines the kind of substrate it will bind to. Enzymes, generally, catalyze reactions by binding to a substrate at their active site. This binding follows a lock and key pattern or model. In a nutshell, the primary source of specificity of enzymes is attributed to their SHAPE, which relates to the lock-and-key model.

Answer:

Hair is made of a tough protein called keratin. A hair follicle anchors each hair into the skin. The hair bulb forms the base of the hair follicle. ... Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life, if that answers your question.

Explanation:

The six (6) regions of the  human body from which hair can  be derived are:

1. Head.

2. Eyebrow.

3. Beard.

4. Pubic area.

5. Body.

6. Armpit (underarm).

Hair can be defined as a threadlike, keratinous filament that typically grows out of the epidermis. Also, an epidermis is the outer layer of the skin.

Basically, the hair comprises two main parts and these are:

Explanation:

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited. In other words, it is the gradual growth of an ecosystem over a longer period of time.

In the primary succession, species like algae, fungi, and lichens are preset. In the secondary succession, the pioneer species present, that already existed in the environment.

One of two types of biological and ecological succession of plant life. They are primary succession that takes place in environments where fresh substrate is deposited that is devoid of plants and other species that typically lack soil, such as lava flows or areas left behind from glaciers that have receded.  

In other words, it is the steady development of an ecosystem through time.

Thus, Algae, fungus, and lichen species are established during the primary succession. The pioneer species that were previously existing in the habitat are found in the secondary succession.

Answer:

Here, we have a composition passage and we are required to fill in the with missing words. The missing words are highlighted in bold format and underlined.

Lecithins and cephalins are both glycerophospholipids; they consist of glycerol with fatty acids forming ester bonds with the first and second hydroxyl groups. The third hydroxyl group of the glycerol forms a phosphate bond with phosphoric acid, which forms another phosphate bond with an amino alcohol. In lecithins, the amino alcohol is choline; in cephalins, the amino alcohol is usually ethanolamine.

Explanation:

Lecithin is a chemical complex composed primarily of fatty acids, glycerol, phosphoric acid, and choline. It can be present in egg yolks, soybeans, sunflower seeds, and plant seed cells and is completely normal. Soybean and sunflower lecithins contain much more important fatty acids than rapeseed lecithin, making them nutritionally more useful.

Phosphatidylethanolamine, also known as cephalin, is a phosphoglyceride that, like phosphatidylcholines and lecithins, is a component of biological membranes. A glycerol residue esterified by two fatty acids and a phosphoethanolamine residue gives rise to phosphatidylethanolamines. They're made by combining CDP-ethanolamine with diglycerides and releasing a CMP molecule. Phosphatidylcholines are formed when S-adenosylmethionine methylates the amine in ethanolamines. They're mostly found in the inner layer of plasma membranes' lipid bilayers.

The most likely direct result of this alteration is that the bacterial DNA will stop replicating. Thus, the correct option for this question is A.

The drug Rifampin is used to treat tuberculosis (TB) in many different parts of the body. It is also used by patients who have meningitis bacteria in their nose or throat who do not show symptoms of the infection to prevent the spread of the bacteria to other patients.

Rifampin specifically inhibits bacterial RNA polymerase. It is an enzyme that is responsible for DNA transcription, by forming a stable drug-enzyme complex with a binding constant of 10(-9) M at 37 C. The corresponding mammalian enzymes are not affected by rifampin.

Therefore, the most likely direct result of this alteration is that the bacterial DNA will stop replicating. Thus, the correct option for this question is A.

Answer:the diagram illustrates the results of non disjunction during gamete formation.

Explanation:

The following statements concerning the karyotype in the diagram is true - The diagram illustrates the results of nondisjunction during gamete formation.

Karyotype refers to the number and appearance of chromosomes present within the nucleus of a eukaryotic cell. It is illustrated as a diagram such as given in the question.

There is no Down's syndrome as the karyotype demonstrates a normal pair of chromosome 21.  In this karyotype, there is an extra X-chromosome that depicts non-disjunction during either oogenesis or spermatogenesis (gamete formation) in the parents leading to the 23rd trisomy.

Genotype of night blind woman -  XnXn

Genotype of normal man - XY

Explanation:

Given

Night blindness (n) is a sex-linked recessive trait. Let us say it is X linked recessive

In this case a man with XY genotype having a diseased X allele will be night blind while a woman will have night blindness if both the X allele are diseased  . In case if only one X allele is diseased in women then, she will be a carrier of night blindness defect

Genotype of night blind woman -  XnXn

Genotype of normal man - XY
