Chose "A" like applesssss If im wrong you can roast me
B) small non-polar molecules. Small molecules can pass through the cell membrane through diffusion (does not require energy). The molecule being non-polar is an advantage because the tails of the phospholipid bilayer is hydrophobic (nonpolar), so it does not repel nonpolar molecules.
<h2>A) option is correct </h2>
Explanation:
- RNA is a linear polymer of ribonucleotides
- Sugar in RNA is ribose instead of deoxyribose which is present in DNA
- The four nitrogenous bases present in RNA are adenine, cytosine, guanine and uracil whereas that in DNA are adenine, cytosine, guanine and thymine
- RNA molecules carry genetic information from DNA to proteins, cannot transmit from one generation to next generation as a genetic material
- Due to steric hindrance by the 2'-OH group of ribose sugar, RNA unable to form double helix
These cells consume bacteria and other pathogens to protect the body from infection. The process begins when chemicals from a pathogen, or damaged tissue, attract a phagocyte. The phagocyte binds to the microbe, envelopes it, and then eats it.
The last stage of embryonic development where the embryonic stem cells are found is the blastocycst. In this stage the cell differentiates and group themselves into different body parts and specialized cells. This stage is reached with in the period of 3 to 5 days of the embryo development.
