If a species has 35 percent adenine in its dna, what is the percentage of the other three bases?

Biology
1 answer:
Basile [38]3 years ago
7 0

Answer:

The percentage of other bases are: Thymine = 35%, guanine = 15% and cytosine = 15%.

Explanation:

There are four bases in DNA molecules, the bases are adenine, thymine, guanine and cytosine. The quantity of adenine and thymine are always equal, so also, the quantity of guanine and cytosine are always equal. Based on the information given in the question, Adenine = 35%, this implies that thymine too is 35%. The two bases added together give 70% , leaving only 30% for guanine and cytosine. Cytosine and guanine will share this equally and so each one of them will have 15%.

why would having both polar and nonpolar properties in a protective boundary be advantageous for the cell?
Reika [66]

Explanation:

The polar nature of the membrane’s surface can attract polar molecules, where they can later be transported through various mechanisms. Also, the non-polar  region of the membrane allows for the movement of small non-polar molecules across the membrane’s interior, while preventing the movement of polar molecules, thus maintaining the cell’s composition of solutes and other substances by limiting their movement.

Further explanation:

Lipids are composed of fatty acids which form the hydrophobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backbone) with up to 36 carbons. Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties i.e. they are amphiphilic. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

Similarly via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins; these allow large molecules called solutes (including essential biomolecules) to cross the membrane.

How do most small molecules cross the cell membrane?
GarryVolchara [31]

Answer:

the structure of the lipid bilayer allows small,uncharged substances such as oxgen.and the carbondioxiode,and hydrophobic moleclues such as lipid to pass through the cell membrane

Herring, a type of fish that is an important winter food source for sea lions, congregate in Prince William Sound, Alaska. What
Ray Of Light [21]
The answer would be (C). If more herring emigrate (leave) from the region, then there will be less herring for the sea lions to use as a food source. This could lead to a decrease in the sea lion population.
