Answer:
The correct answer is - growth and development.
Explanation:
Mitosis is one of the cell division cycles that occurs in the somatic cells. It is characterized by producing the two daughter cells by dividing one parent cell which is an exact copy and the same number of chromosomes.
The major importance of mitosis in the life cycle of an organism is growth and development by producing more cells and rapid in numbers. The cells divide in the mitosis for the major purpose of tissue repair and growth of organisms.
Thus, the correct answer is - growth and development.
Answer:
The correct answer would be cell organelles.
Cell organelles refer to the sub-cellular components which perform specific functions. For example, ribosomes, mitochondria, nucleus et cetera.
Most of the cell organelles are common to all types of cells whether unicellular organisms or cells of multicellular organisms.
For example, ribosomes, lysosomes, vacuoles et cetera are common in all cells.

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.

Assaying the samples in triplicate is a way of control.
Using triplicates will allow you to account for variation within the assay (intra-assay variation). This means that if you do not get the same result in all triplicate wells, you probably have a problem with experimental technique or you have made a pipetting error, so the experiment should have be repeated.
Running an ELISA assay in triplicate increases the reliability and accuracy of results by providing a means of calculating the average from three measurements and mitigating the impact of random errors or procedural inconsistencies. Replicating the assay helps to ensure that results are robust and that variations in individual steps of an experiment do not significantly skew the data.
Completing an ELISA assay in triplicate helps to improve the accuracy of results by addressing statistical variability and potential procedural errors. Testing in triplicate ensures repeated measurements of the same sample, reducing the effect of random errors across the tests and thereby enhancing the reliability and consistency of the data collected.
In a situation where a scientist is measuring the amount of a specific protein in a blood sample, even slight inconsistencies in procedures could impact the results. For example, if the secondary antibody is not washed off thoroughly in one test, it might lead to a false increase in signal strength indicating a higher protein level than actually present. Running the assay in triplicates can mitigate this, as the outlier value can be spotted by comparing it against the other two measurements. It also allows the scientist to calculate the mean value of the three tests, providing a more robust estimation of the protein level. Thus, doing ELISA in triplicate better ensures that your results are reproducible and accurate.
Additionally, each ELISA reaction is a complex process involving a series of binding, washing, and coloring steps. Variations can creep in such as pipetting errors, uneven incubation temperatures, or variation in color development times. Hence reliable and repeatable results in scientific experiments often involve running multiple replicates, including in ELISA assays.
