Answer:
The correct answer will be- the cell structures undergo repeated breakdown and formation.
Explanation:
The carbohydrates, fatty acids and amino acids are the three important bio-molecules which form the components of various cellular structures.
In the given question, the cell biologist radiolabeled these biomolecules and then observed the cellular structures after cell metabolism. He found that few cellular structures contained radiolabeled structures and few not. This showed that the cellular structures constantly undergo changes in their structures due to cellular metabolic reactions and are broken down and reformed.
Thus, the cell structures undergo repeated breakdown and formation is the correct answer.
Answer:
Amino acids are organic compounds: meaning they contain carbon, hydrogen, oxygen and nitrogen. They are the building blocks, or monomers of proteins. They are made of a carboxyl group and an amino group. There is also a side chain, that is different for each of the 20 amino acids.
Hope this helps! :)
Carbohydrates are sugars that come in 2 main forms - simple and complex. This is also referred to as simple sugars and starches. The difference between a simple and complex carb is in how quickly it is digested and absorbed - as well as it's chemical structure.
Answer:
I would say the last one is not true. D) Chromosomes are first visible during Interphase.
Hope I helped. ;)
Explanation:
Answer:
Is used to prevent contamination from pathogens.
Explanation:
Pathogens are disease causing organisms. In a clinical setting or even in the laboratory, a person has to use the strictest means of disease prevention and even re-infection (for patients). Aseptic technique is important to protect yourself, other workers and patients from infection and from the spread of pathogens. It effectively maximizes the presence of pathogens and totally eliminate them. This is possible from simple measures like using your PPE which must all be sterile. From your gloves, gowns etc to your equipments used during any procedure. Also disinfection of your work place is important too either by concurrent disinfection or intermittent disinfection.
