Which list best describes what should be worn by students in a biology lab where pouring chemicals into beakers is involved?a long-sleeved shirt, safety glasses, protective gloves, and sandals
a long-sleeved shirt, safety glasses, protective gloves, and closed shoes
a lab coat, safety glasses, protective gloves, and sandals
a lab coat, safety glasses, protective gloves, and closed shoes

Answers

Answer: Option (d) is the correct answer.

Explanation:

In a laboratory, while performing an experiment it is necessary to follow necessary safety measures so that any misshapen may not result in a serious injury.

Therefore, when we pour chemicals into a beaker then it is advisable that we should be wearing safety glasses so that any spurting won't let the chemical to enter in our eyes. Protective gloves will save our hands from coming directly in contact with the acid.

Whereas a lab-coat and closed shoes will protect our rest of the body from the chemicals.

Thus, we can conclude that a lab coat, safety glasses, protective gloves, and closed shoes is the list of materials to be worn while performing an experiment.

it is the last one :) :) :)

Which element found in both biotite mica and muscovite mica, makes up the greatest percent by volume of earths crust.

Answers

Answer;

Oxygen

Explanation;

Oxygen is the element that is found in both biotite mica and muscovite mica and makes up the greatest percent by volume of earths crust.
The most common chemical elements that are found in the earth's crust includes; Oxygen-46.6%, silicon-27.7%, aluminium- 8.1%, Iron - 5.0%, calcium- 3.6%, etc. This is evident that oxygen is the greatest chemical element in the earth's crust.

The chemical element oxygen is also found in minerals biotite mica and muscovite mica. The major difference is that Biotite contains elements iron and magnesium while muscovite does not.

Oxygen is your answer.

A major group of G protein-linked receptors contain seven transmembrane alpha helices. Where would you expect to find the portion of this receptor that interacts with the signaling ligand? A) within the membrane interior B) at the exterior surface C) at the cytosol surface D) in the interior of the Golgi

Answers

Answer: (B) At the exterior surface

Explanation:

G protein-linked receptors (GPLR) are also called G protein-coupled receptors, 7-Transmembrane receptors or heptahelical receptors. They conform a large protein family of receptors.

They helps to detect molecules (ligands) outside the cells. (At the exterior surface).

The LIGANDS that binds and activate these receptors include light-sensitive compounds (Opsins), odorants (olfactory receptors), pheromones (vomeronasal receptors which are situated near the vomer bone between the nose and the mouth), hormones and neurotransmitters (serotonin, dopamine, glutamate etc).

Let's take a bird's eye view at it.

° When a Ligand binds with a G protein-linked receptors (which occurs at the exterior surface), it undergoes a conformational change.

° As conformational change occurs, GPLR become active and interact with the G-proteins Heterotrimeric Subunits ( G-alpha, G-beta, G-gamma) in the plasma membrane (at the cytosol surface).

This step typically explains the ambiguity. i.e GPLRs receptors interacts with signaling ligands via the exterior surface but communication between GPLRs and G-proteins Heterotrimeric Subunits occurs in the cytosol membrane.

Hence, this Conformational Change then triggers the interaction between the GPLRs and a nearby G proteins.

I hope that helps!.
