A cell membrane that transports glucose, ions, or other charged or polar molecules is likely to have a higher percentage and gre
erica [24]

Answer: True

Explanation:

<u>A cell membrane consists of a lipid bilayer made of polar phosphate head and a nonpolar lipid tail.</u> It is semipermeable and regulates the transport of materials through it. For this,<u> it is selectively permeable</u> and since it is made of lipids, hydrophobic and small polar molecules can diffuse easily through it by simple diffusion and down their concentration gradient. However, polar molecules, large molecules (such as glucose) and ions are not able to pass through it because they are repelled.

To accomplish the transport of these molecules that can not diffuse, proteins embebbed in the membrane function as carriers that enable the transport of polar molecules, large molecules and ions by passive (through facilitated diffusion, down its concentration gradient) or active transport (movement against its concentration gradient).

How is RNA and DNA different
Shkiper50 [21]

-DNA is double stranded,RNA is one stranded

-DNA contains the following nitrogenous bases:Adeninde Guanine Timine Citozine while RNA contains Adeninde Guanine Citozine and Uracil

-DNA function is to contain the information for manufacturing proteins while there are many types of RNA with whole different jobs for example:messanger RNA(mRNA) it coppies a sequence from the DNA strand and takes it to the ribosome in order to be translated as the order for placing aminoacids in the polypeptide strand;transport RNA(tRNA) it is a short RNA strand containing up to 100 nucleotides it takes aminoacids to the ribosome so the polypeptides strand can start to be manufatured from aminoacids in an order inscripted in the mRNA.

Prokaryotic DNA is enclosed within a nucleus, while eukaryotic DNA is not.<br>O True<br>O False​
blagie [28]

Answer:

False

Explanation:

Prokaryotes do not have a nucleus.

This means their DNA is not enclosed in a nucleus and instead is in the cytoplasm.

On the other hand, eukaryotes have nuclei, so their DNA is enclosed within a nucleus.

So, this statement is false.
