which one of the plants pictured below was given water mixed with salt, and which one was given pure water? Explain how you know
ludmilkaskok [199]

The plant on the right must have been the one given a saltwater mixture while the one on the left must have been given pure water.

<h3>Osmosis</h3>

Looking at the attached image closely, one would see that the plant on the right has withered leaves while the leaves of the plant on the left seem to be flourishing.

The plant on the right must have been the one fed with water mixed with salt and here is the reason. Adding water mixed with salt to the soil on which the plant grows will decrease the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the plant into the soil through the root by osmosis. This will cause the various cells of the plant to become flaccid, and hence, the withered leaves.

On the contrary, the plant on the left must have been fed with pure water. Feeding the soil with pure water will increase the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the soil into the plant through the root by osmosis. This will cause the various cells of the plant to become turgid, and hence, the flourishing leaves.

VashaNatasha [74]

Answer:

Cells vary greatly in shape These shapes are often related to the function they perform. like the disk shape of  erythrocytes  can absorb and transport oxygen due to increased surface area., the amoeboid shape of leukocytes allow them to squeeze through capillaries. etc.

Explanation:

Cells can be disc-like , polygonal, rectangular, cubopid thread like branched or even irregular. these are related to the functions that each cell performs.

Some examples showing relation between cell shape and function are as follows.:

  • Human blood cells are circular and biconcave to transport oxygen.
  • White blood cell are amoeboid to squeeze through thin capillaries.
  • Nerve cells are long so that they can carry nerve impulse to a long distance very quickly.
  • Guard cells of stomata are bean or dumbell shaped to open and close the stomata.

Dna molecules can be tens of thousands of base pairs in length. mistakes in dna replication lead to mutations, which may or may
DIA [1.3K]
The answer is "<span>Half of the strand is already correct and does not need correction".

Semiconservative replication would create two duplicates that each contained one of the first strands and one new strand. Moderate replication would leave the two unique format DNA strands together in a twofold helix and would create a duplicate made out of two new strands containing the greater part of the new DNA base sets.
