Identity the process that occurs in this organelle, and explain the importance of
this process to the survival of organisms

Answers

not sure if this is what you need.

The process that occurs in this cell organelle known as mitochondria is cellular respiration. The importance of this process is understood by the fact that it derives energy for the accomplishment of metabolic functions.

What is a Cell organelle?

A cell organelle may be defined as a type of small structure that is present inside a cell and is significantly surrounded by a membrane in order to perform a specific function for the overall survival of an organism.

This process in the mitochondria is known as cellular respiration. Through which the molecules of glucose are significantly broken down in the presence of oxygen in order to liberate energy in the form of ATP which is known as the energy currency of the cell. The ATP that is produced by this reaction or process carries out all essential functions of life.

Bacteria cells can be used to produce insulin for the treatment of diabetes in humans. Which best explains how the bacteria cells are able to produce insulin for humans? (8.L.2.1) *
A. The bacteria have been grown on a petri dish containing insulin.
B. The bacteria have been genetically engineered to contain the DNA needed to produce insulin.
C. The bacteria have been exposed to radioactivity to create mutant strains capable of producing insulin.
D. The bacteria have been grown on a petri dish containing sugar; the bacteria produce insulin in response to the sugar.

Answers

Answer:

Your answer is B), I took this quiz already.

The statement 'bacteria have been genetically engineered to contain the DNA needed to produce insulin'' BEST explains how bacterial cells are able to produce insulin for humans (Option B).

Recombinant DNA (rDNA) refers to the genetic engineering strategies used to create genetically modified organisms capable of expressing exogenous DNA sequences.

The rDNA technologies involve the use of specific proteins that cut (restriction enzymes) and paste (ligase enzymes) target nucleotide (DNA) sequences in order to design organisms containing such sequences.

The recombinant DNA can be expressed into a suitable vector (in this case, bacteria) in order to produce a protein of interest (e.g., insulin).

In conclusion, the statement 'bacteria have been genetically engineered to contain the DNA needed to produce insulin'' BEST explains how bacterial cells are able to produce insulin for humans (Option B).

Solve for X. 2y-4x=10 While dry cleaners are small businesses, they generate relatively large volumes of hazardous substances. EPA estimates the average dry cleaner generates 660 gallons of hazardous wastes a year. Unlike petroleum contamination which may break down over time by naturally-occurring bacteria in the environment, the chlorinated solvents that are used by dry cleaners are resistant to biodegradation. As a result, groundwater contamination from dry cleaners has a greater potential to migrate off-site which can be problematic since dry cleaners are often located within proximity to residential neighborhoods. Indeed, a 2002 Florida study found that dry cleaner contamination had migrated off-site at 57 percent of the contaminated sites.
