What significant role does dna play in formation and development of an organism

Answers

DNA contains the instructions needed for an organism to develop, survive, and reproduce.

What is DNA?

Cells' capacity to store, retrieve, and translate the genetic instructions necessary to create and maintain a live organism is essential to life.

This genetic material is transmitted from one generation of an organism to the next through the reproductive cells of the organism and from one cell to its daughter cells during cell division.

Every living cell contains these instructions as part of its genes, which are the information-containing components that define the traits of a species as a whole and of the individuals within it.

Therefore, DNA contains the instructions needed for an organism to develop, survive, and reproduce.

Answer:

DNA contains the instructions needed for an organism to develop, survive, and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

in a well-fed state, brain cells use which one of the following compounds circulating in the blood stream almost exclusively as an energy source?

Answers

Glucose is virtually the sole fuel for the human brain, except during prolonged starvation. The brain lacks fuel stores, thus requires a continuous supply of glucose. It consumes about 120 g daily which corresponds to an energy input of 420 kcal (1760 KJ), accounting for some 60% of the utilization of glucose by the whole body in the resting state.

In order to protect off of aquifers near landfills material is placed under the soil to prevent pollution which property must the protective material process

Answers

Answer: Permeability. 

This property allows liquids to pass through the material but also filters out pieces of garbage and other pollutants. In aquifers, permeable rocks or synthesized permeable material are used so that trash, or clay will not leak into the groundwater. 

The answer is impermeability. The protective materials prevent the leakage and seepage of contaminated water (such as those of battery acid and household cleaners), by gravity, to the water table in the aquifer. If this is not done, contamination of groundwater may result and cause a public health disaster when the contaminated water is used for consumption when it reaches water wells.

Answers

The clinical microbiologist is setting up a minimum inhibitory concentration (MIC) test.                                                                    

In this test, the microbiologist makes serial dilutions of various antimicrobial drugs in broth and then incubates each drug dilution with a standard amount of the patient's isolated pathogen. The MIC test helps determine the lowest concentration of an antimicrobial drug that can inhibit the growth of the pathogen. This information is crucial for determining the most effective treatment for the patient
The clinical microbiologist is setting up a Minimum Inhibitory Concentration (MIC) test. This test involves creating serial dilutions of various antimicrobial drugs and incubating them with a patient's isolated pathogen. The MIC test helps determine the lowest concentration of an antimicrobial drug that can inhibit the growth of the pathogen. This information assists healthcare professionals in selecting the most effective treatment for the patient.

How are the three chromosomal aberrations different from each other?

Answers

The three chromosomal aberrations are: (1) Inversion; (2) Translocation and (3) Deletion. They are all different as they have opposing functions of repairing, changing or removing chromosomal differences. Inversion involves breaking the chromosome and inserting another part; translocation involves a part of the chromosome moving to another place, and deletion is where parts are simply deleted and removed.

Chromosomal aberration is referred to as the abnormalities in chromosome and they are of many types. They are different from each other because;

Duplication: It duplicates the specific part of a chromosome and leads to extra genetic material.

Deletion: In this, deletion or disappearance of a specific sequence of a chromosome occurs.

Translocation: In this one portion of a chromosome is transferred to another chromosome.

Further Explanation:

If there is any defect in the chromosome or the sequence of the chromosome, then this condition is referred to as chromosomal aberration. These problems give physical abnormalities or symptoms in an individual. Chromosomal aberration could be developed due to the addition of a particular portion in the chromosome or deletion of a particular sequence from the chromosome. It affects the normal functioning of the chromosome. The two types of chromosomal aberration are:

Numerical aberration: It develops due to the presence of an extra number of the chromosomes or lack of chromosome. For example, Turner syndrome and Down syndrome.

Structural aberration: This is developed due to abnormality in the genetic material or loss of genetic material.

Structural aberrations are of many types. Few of them are:

Deletion: In this, a particular sequence is missing from the chromosome.

Duplication: In this, some part of the chromosome is duplicated.

Translocation: In this, part of the chromosome is moved to another chromosome.

Inversion: In this, the genetic material of a chromosome is inverted due to breakage.
