The topical agents that are helpful in cleaning highly colonized wounds are the following; sodium hypochlorite, acetic acid and hydrogen peroxide. These topical agents are helpful in cleansing the wound and will likely help in healing the wound as it does not damage the tissues.

Answer;

-Produced

Water is produced when a nucleotide is added to the end of a DNA strand.

Explanation;

Nucleotide is a monomer in nucleic acids, consisting of a five-carbon sugar covalently bonded to a nitrogenous base and (1-3) phosphate groups.

-The polymerization of nucleotides is a condensation reaction. condensation reaction is the chemical reaction in which two or more molecules combine to produce a simple molecule that happens in nucleic acid synthesis. (like hydrolysis but not water product). For a covalent bond to form between the nucleotide and DNA strand, an OH from the nucleotide and an H from the strand of DNA combine to form water.

When two or more tissues join together for a specific function, they form an organ. Examples include the heart, liver, and lungs.

When two or more tissues join together for a specific function, they form an organ. Examples include the heart, which is made up of cardiac muscle tissue, connective tissue, and nerve tissue; the liver, which is made up of various types of tissues including hepatocytes and blood vessels; and the lungs, which are made up of respiratory epithelium, smooth muscle, and connective tissue.

The answer to the statement will be true

The maximum life span that an individual of a given species could reach is referred to as life expectancy. The correct option is 1.

Life expectancy is a measurable statistic of how long an organism is expected to live based on its birth year, current age, and other demographic factors.

The world's current life expectancy in 2016 was 72.0 years, 74.2 years for females, and 69.8 years for males, according to the World Health Organization (WHO).

Thus, the correct option is 1.

Final answer:

According to the FDA food code, foods should not be in the temperature danger zone (40°F to 140°F) for more than two hours to prevent rapid bacterial growth and foodborne illness.

Explanation:

The maximum amount of time allowed by the FDA food code that time/temperature control foods can be kept in the temperature danger zone is more than two hours. The temperature danger zone is defined as the range between 40°F and 140°F, wherein bacteria grow rapidly. Foods that remain within this range for more than two hours may become dangerous to eat due to rapid bacterial growth. Therefore, it is crucial to adhere to this guideline to prevent foodborne illness.

Answer:

The correct answer will be option-C.

Explanation:

A scientific theory is a well-substantiated idea which explains any natural phenomenon in depth. The theory is the elaborate and explanatory form of a hypothesis which has to prove through experiments.

The theories are formed by the use of many earlier theories which explains the same natural issue like Theory of relativity by Einstein. Before the theory is accepted it must be supported by the experiments of the work of another scientist as well as earlier theories. It should be tested with other scientists working on the same issue.

Thus, Option-C is the correct answer.

Explanation:

Cross sectional study is form a class of research methods that involve observation of all of a population, or a representative subset, at a defined time. Longitudinal study is a correlation research study that involves repeated observations of the same items over long periods of time — often many decades. It is a type of observational study.

Some parts of an object may be in and out of focus under a microscope due to differences in specimen depth and because high magnification lenses require precise focusing. Objective lenses are parfocal, aiding in maintaining focus when switching magnifications, and the eyepiece further magnifies the image to create a clear view for the observer.

When you are focusing an object under the microscope, some parts may be in focus while others are out of focus because of differences in depth within the specimen, which is being magnified by the microscope's lenses. The first lens, the objective lens, typically has magnification values from 5x to 100x and is mounted to be parfocal, meaning it keeps the specimen nearly in focus when switching between magnifications. The second lens, the eyepiece or ocular, contains several lenses and works with the objective lens to magnify the object further.

When viewing the specimen, the field of view is limited and dependent on the combination of eyepiece and objective lens used. As the objective lens magnifies the object, the working distance between the lens and the specimen decreases. High magnification lenses require fine adjustments to the focus, using the fine focus knob, to bring a very small and specific area of the specimen into focus.

Lenses focus light at an image point by bending the light waves that pass through them. The focal length of a lens is the distance over which these rays are refracted to a single point, and it can be affected by factors such as lens curvature, the refractive index of the lens material, and the wavelength of the incoming light.

When focusing a microscope, the parts of the object within the depth of field will be in focus, while others will not. Increasing magnification decreases the depth of field, making fewer parts appear clear. Using the fine focus knob helps bring different parts into view.

When you focus an object under a microscope, the parts that are in focus lie within the depth of field of the lens. The depth of field is the range of distance within which objects appear sharp and clear. As you increase magnification, the depth of field decreases, making fewer parts of the specimen appear sharply focused. This is why some parts of the object are in focus while others are out of focus. Using the fine focus knob can help achieve a more precise focus and bring different parts of the object into clear view. Imagine you are observing a leaf under a microscope. At low magnification, you might see the entire leaf surface clearly. However, when you switch to higher magnification to look at the cells, only a thin layer of cells will be in focus while cells above and below that layer appear blurry.

A decrease in the decomposition rate in an ecosystem will impact the nitrogen cycle such that the amount of nitrogen available in the soil decreases.

Decomposition of dead organic matters in ecosystems releases nitrogen into the soil in the form of ammonium compounds.

The more the decomposition activities in an ecosystem, the more the amount of nitrogenous compounds available in the soil.

Thus, a decreased decomposition rate in an ecosystem will reduce the amount of nitrogen available in the nitrogen cycle, specifically in the soil.

Low-Density Lipoproteins (LDL) is broken down to protein and free cholesterol. Used for maintaining cell membrane or synthesizing special compounds (estrogen, testosterone, vitamin). Oxidized LDL in the blood is picked up by the Scavenger pathway for Cholesterol Uptake. The WBC sense oxidized LDL, digest and overcome it which avoids it from re-entering the blood stream which able to pick up vast amounts of LDL.

Explanation:

A basic amino group (NH2), an acidic carboxyl group (COOH), and an organic R group (or side chain) that is specific to each amino acid make up an amino acid, an organic molecule. Therefore, option (B) nitrogen is correct.

Organic substances known as amino acids have both amino and carboxylic acid functional groups. Alpha-amino acids, which make up proteins, are by far the most significant of the hundreds of amino acids found in nature. In the genetic code, only 22 alpha amino acids are present.

Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the necessary amino acids. Alanine, asparagine, aspartic acid, glutamic acid, and serine are the non-essential amino acids.

Carbohydrates and fats consists of carbon, hydrogen and oxygen. Therefore, Option (B) is correct. Nitrogen is present in all amino acids but not  necessarily in fats or carbohydrates.
