Which of the following is NOT an item associated with Biotechnology? O Bioremediation
O Chemical Reactions
O Vaccinations
O Antibiotics

C. Chemical reaction

Explanation:

✔️ Bioremediation is a branch of biotechnology that employs the use of living organisms, like microbes and bacteria, in the removal of contaminants, pollutants, and toxins from soil, water, and other environments. Bioremediation is used to clean up oil spills or contaminated groundwater.

❗️NOT A)

A biochemical reaction is the transformation of one molecule to a different molecule inside a cell. Biochemical reactions are mediated by enzymes, which are biological catalysts that can alter the rate and specificity of chemical reactions inside cells.

May not be b

✔️ Biotechnology is mainly used in three ways as follows: separation of a pure antigen using a specific monoclonal antibody; synthesis of an antigen with the assistance of a cloned gene; and synthesis of peptides to be used as vaccines.

❗️NOT C)

✔️ Antibiotics. Antibiotics are biotechnological products that inhibit bacterial growth or kill bacteria. They are naturally produced by microorganisms, such as fungi, to attain an advantage over bacterial populations. Antibiotics are produced on a large scale by cultivating and manipulating fungal cells.

Not d)❗️

58750.08068 is the answer i think

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
