Can H2O pass through a lipid bilayer

Biology
2 answers:
goblinko [34]2 years ago

Answer:

Here's an answer that might help you! I hope this helps! :) Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.

Which of the following statements best compares genetic diversity in eukaryotes and prokaryotes?
cestrela7 [59]

Answer:

C. Mutations increase the genetic diversity in both prokaryotes and eukaryotes.

Explanation:

It is a well-established fact that mutations increase the genetic diversity in living organisms (especially if they are positive mutations). The positive and faster mutations will help the organism to develop better traits for survival in the changing environments.

The other options are incorrect because of the following reasons:

A. Eukaryotes don't do gene transfer via conjugation.

B. Eukaryotic species don't experience a greater rate of mutations as compared to the prokaryotes. Prokaryotes have a faster mutation rate. This is the reason that microbes can adapt to changing environments faster than humans or other multicellular organisms.

D. As mentioned above, sexually reproducing eukaryotic species evolves slower than the asexually reproducing species. For example, evolution in bacteria (e.g. drug resistance) is faster than any organism belonging to eukaryotic lineage.

What is the function of the amino functional group?
stealth61 [152]

I found this info if this is what you need link http://www.answers.com/Q/What_are_the_functional_groups_of_amino_acids

Two functional groups are found in all amino acids. These functional groups are the  

amino group

(-NH2) and the  

carboxyl group

(-COOH). The hydrogen atom of the carboxyl group can be broken off quite easily; this gives amino acids their acidic properties.  

Function of amino acids?

Heat and Energy, Growth, To defend against disease, and to Repair bodily cells are the functions of amino acids/ proteins.  

Amino acids contain a carboxyl group?

Yes, amino acids contain: 1) an amino group (-NH 2 ) 2) a central carbon and variable side group 3) a carboxyl group (-COOH)  

What is the function of amino acids?

Amino acids are nitrogen-containing molecules that serve vitalfunctions in your body. Twenty-two amino acids occur in nature, and20 of these are incorporated into proteins and other moleculeswithin the cells and tissues of plants and animals. According toscientists at the University of Arizona, your body can synthesize10 of the amino acids you need, while the other 10 must be acquiredfrom your diet. Amino acids that cannot be produced within yourcells are called essential amino acids. http://www.livestrong.com/article/426255-what-is-the-function-of-amino-acids-in-the-human-body/  

What is the amino group on an amino acid?

The amino group is present at one end of the amino acid and is represented by the chemical formula NH 3 The region on the amino acid that contains the amino group is called the amino terminal  

Amino acid function?

Amino acids are basically known as the building blocks of protein.The function of an amino acid is primarily to build proteins.

How do the heart and lungs work together
MrRa [10]
Heart and lungs works hand in hand. Not only that they are close to each other but they also work to make sure that body gets enough oxygen that it needs to live. It is the heart that pumps blood through the body it passes through the lungs. then it is the job of the lungs to supply oxygen together with the blood that heart pumps.
