Answer:

A battery is a device that stores chemical energy, and converts it to electricity. ... In an electrochemical cell, electrons are produced by a chemical reaction that happens at one electrode (more about electrodes below!) and then they flow over to the other electrode where they are used up.

Hitman42 [59]

The right answer is facilitated diffusion.

Facilitated diffusion is a diffusion mechanism facilitated by membrane transporters. it's the spontaneous passage of molecules or ions (like the passive diffusion) through a biological membrane through transport molecules (unlike passive diffusion). This process does not consume energy (like the passive diffusion) and therefore does not involve active transportation.

“The genetic code is universal.” This statement means that
Lemur [1.5K]

The correct answer is B

The genetic codes language in all living organisms is the same. This is to say that the molecules of life namely DNA and RNA share the same make up in all living things .

There are five types of nucleotides in nature which are the building blocks of RNA and DNA and these are the same in all living organisms . These nucleotides are Adenine, Thymine, Guanine, Cytosine and Uracil.

According to base pairing rules, in all DNA molecules Adenine will always pair with Thymine while Guanine will always pair with Cytosine.

This  rule is the same with RNA except that here Thymine is replaced with Uracil.  Otherwise the base pairing rule applies in all living organisms, that is to say it is universal.

Medicines are often administered in pill form. In many cases, the active ingredient of the pill (the drug) is joined to another
Natasha_Volkova [10]

Answer:

Option B, ionic bonds; salt

Explanation:

All medicines either in the form of pills or liquid interact with our body by forming a bond with target specific receptors. For instance if a pain killer is taken then it shall form bond with receptors produced by pain and inflammation

So medicines are basically chemical which interact with biomolecules such as enzymes, nucleic acid, hormones, ions etc. by forming ionic bond, hydrogen bond, van der wall force etc. in the active site of enzyme.    

These salt molecule remain stable in normal conditions but as they come in contact with digestive system of the body (with different pH) they release the drugs

Hence, option B is correct
