Answer:

This is important for laboratory safety.

Explanation:

It is important to read the Material Safety Data Sheet because it will inform you on what is being used in the lab and what to do/what not to do when chemicals or any materials are being involved.

Parasitic plant and insecticide plant defination​
Elina [12.6K]

parasitic plant = A parasitic plant is one that survives at the expense of another, often living and growing on and over the host plant, while siphoning off the other plant’s nutrients and water, and sometimes blocking access to sunlight.

insecticide plant = Insecticide, any toxic substance that is used to kill insects. Such substances are used primarily to control pests that infest cultivated plants or to eliminate disease-carrying insects in specific areas. insecticide application. A farmer sprays insectides in a rice paddy in Japan.

what is the meaning of phosphoryl transfer potential and what does it mean to have a high or low phosphoryl transfer potential?
makvit [3.9K]

Phosphoryl-transfer potential is the ability of an organic molecule to transfer its terminal phosphoryl group to water which is an acceptor molecule. It is the “standard free energy of hydrolysis”.

Explanation:

This potential plays a key role during cellular energy transformation by energy coupling during ATP hydrolysis.  

A compound with a high phosphoryl-transfer potential has the increased ability to couple the carbon oxidation with ATP synthesis and can accelerate cellular energy transformation.  

A compound with a high phosphoryl-transfer potential can readily donate its terminal phosphate group; whereas, a compound with a low has a lesser ability to donate its phosphate group.

ATP molecules have a high phosphoryl transfer potential due to its structure, resonance stabilization, high entropy, electrostatic repulsion and stabilization by hydration. Compounds like creatine phosphate, phosphoenolpyruvate also have high phosphoryl-transfer potential.

Which one of the following is the correct sequence of events that correlates to the sequence of events of a nerve impulse?
quester [9]

Answer:

the correct sequence of the events happened during nerve impulse is (d): 2,1,4,3

Explanation:

Originally K+ ions remains inward the membranes while Na+ ions remains outward to maintain a resting potential of membrane.

Upon stimuli Sodium channels open on membrane and Na+ diffuses inward leading to the depolarization of membrane that is it becoming more positive due to Na+ and K+ ions.

To regain it polarized state or in repolarization state Potassium channels open and K+ begun to diffuse outward while Sodium channels gets closed and Na+ ions remains inside the membrane.

Potassium channels are not efficient as compared to Sodium Channels, so an excess amount of K+ion move outward so Hyperpolarization state achieved.

As the both ions are on the wrong side and will not be available for the next nerve impulse. Hence in Refractory period by the help of Na+/K+ pum, both ions move back to their original place and membrane achieve its resting membrane potential state.
