Which of Jackie’s actions would violate proper laboratory safety? alerting the teacher about large shards of glass on the floor replacing a beaker that had a crack in the top moving his chemicals away from the lighted Bunsen burner using his mouth to pipette the correct amount of solution into a pipette

Answers

Answer 1

Answer:

Explanation:

Solution

A: You have to alert someone if there is glass on the floor. Consider the kind of shoes that most people wear. It would be a disaster to be cut by something that had contained a chemical. The action is true and therefore A is not the answer.

B: You always replace any glass wear that is cracked. What if it breaks, then what. The answer is a correct answer, and therefore you would not pick B.

C: You always treat fire with care. It's not C.

D: I don't know about you, but I'd be awfully careful about putting my mouth over something that I'm not sure what it would do if I accidently swallowed the contents of the pipette. D is not a good procedure, but it is the answer.

Which of the following correctly shows the sequence of organelles a protein would take if it were being exported from the cell?
(1 point)
O Ribosome → Smooth ER + Vesicle — Cell Membrane → Vesicle → Rough ER
Smooth ER Vesicle → Golgi apparatus → Rough ER → Vesicle → Nucleus
Ribosome > Vesicle - Rough ER → Vesicle → Golgi Apparatus → Cell Membrane
O Ribosome - Rough ER → Vesicle - Golgi Apparatus → Vesicle + Cell Membrane

Answers

When a protein leaves the cell, the proper pathway is Ribosome - Rough ER - Vesicle - Golgi Apparatus - Vesicle + Cell Membrane.

What is membrane trafficking?

Proteins and other macromolecules are transported throughout the cell and released into or internalized from the extracellular space via membrane trafficking. Membrane-bound vesicles serve as transport mediators in membrane trafficking.

Trafficking of protein pathway:

By translating the matching messenger RNA (mRNA) sequences into polypeptides in the ribosomes, proteins are created (translated).The production, processing, and transport of proteins and lipids all depend on the system of endomembrane, which is a system of membranous parts inside the cell.The endoplasmic reticulum (ER), Golgi apparatus, and lysosomes are components of this system.The endomembrane system's components can exchange membrane components with one another and with the cell membrane in the vesicles, which are membrane-bound sacs.

Hence the pathway of protein exporting.
