Plates?

Explanation:

Tectonic Plates are about the only kind of plates I've heard of, besides ones you eat off of. If you are trying to fill in the blank, "plates" should be your best answer.

Answer: Plates

Explanation:

Tectonic plates are the only plates that cover the underside of the Earth. If it isn't this, then scientists must have discovered something new! Hope this helped.

How does the concentration of salt in water affect the rate of osmosis?
Nata [24]
The concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences.
Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.

Slav-nsk [51]

Answer: Option C.

Both

Explanation:

Streptomycin is an antibiotics produced from bacteria and fungi and it is used to treat bacteria infections (prokaryotic ) such as tuberculosis, mycobacterium infection e.t.c.

It's inhibit protein function in prokaryotes because it's affects the function and performance of 70 s RIBOSOMES which is an organelles for protein production.

Streptomycin does not affect eukaryotes because it does not bind to the RIBOSOMES of eukaryotic cells which in turn does not affect protein production.

Four students were asked to classify the activities of the people in the picture below as examples of either potential or kineti
frez [133]

Hi there!

\large\boxed{\text{The first choice.}}

Kinetic Energy (1/2 · mass · velocity²) occurs when an object is in motion, or a force is occurring on the object. An example would be a car in motion.

Potential energy (mass · height · gravity ) is obtained when an object has the ability to do work. An example would be an object on a shelf. It has the potential to fall, and this would cause the potential energy to become converted into kinetic energy.

-----------------------------------------------------------------------------------------------------------

Looking at the examples in the table,  we can sort them as such:

Girl swimming laps- Kinetic energy because the girl is in motion.

Boy on diving board - Potential energy because the boy is not in motion, but has the potential to be in motion.

Girl hitting volleyball - Kinetic energy because the volleyball is in motion.

Boy holding volleyball- Potential energy because the volleyball is stationary and has the potential to be in motion.

Therefore, the correct table is table 1.
