Answer:  

A trans membrane protein is a type of integral protein that is found in the entire cell membrane and the membrane protein is attached to the cell membrane.

Many trans membrane proteins functions as channel or gateway which allows the transport of the specific materials which cannot be transported through other means.

The other materials which cannot be transferred by simple diffusion, osmosis or other means is transported by the trans membrane proteins.

anyanavicka [17]

Answer:

This experiment proved that DNA replicated semiconservatively; half the original polynucleotide is conserved in each of the two copies

Explanation:

Semi-conservative mode of replication means that the two strands of DNA unwind from each other, and each of themacts as a template for synthesis of a new, complementary strand. As a result, two formed DNA moleculesc ontain one original strand and one new strand.

Meselson and Stahl experiment showed this model by labeling the DNA of bacteria across generations using isotopes of nitrogen ( patterns of DNA labeling showed the mode of replication).

What is the different between mechanical digestion and chemical digestion in the mouth?
Alborosie

Answer and Explanation:

The mouth is part of the digestion system.

Mechanical Digestion is the physical motion our mouth makes to chew up the food. We grind up the food with our teeth, then swallow the food into the next part of the digestive system.

Chemical Digestion in the mouth is the saliva our mouth produces. It breaks down the food along side the mechanical part of the mechanical digestion.

For a science experiment. John gradually added a sedium hydroxide (NaOH) solution to warm vegetable oil in a glass test tube. He
Marrrta [24]

The sodium hydroxide solution and vegetable oil underwent a chemical change.

<h3><u>Explanation:</u></h3>

The reaction between a base and a fat or fatty acid is called as saponification reaction. Here the base dissociates into the cation and hydroxyl ion. The hydrogen from the fatty acid of the oil reacts with the hydroxyl ion to form water which is basically the neutralization reaction. This cation now reacts with the rest of the fatty acid to form a bipolar molecule which is the soap. During the reaction, the solution becomes cloudy but with time, it again goes back to solution. The cloudyness appears because oil isn't soluble in water based solutions and the base is actually made solution in water.

Here the sodium hydroxide reacts with oil to form water and the soap molecule which is a chemical change.
