Answer:
The answer is C
Explanation:
Therefore, in order to swim in the English channel, in which its waters are extremely cold, we need carbohydrates like glucose that provide 4 kilocalories per gram. ... Fats are much more energetic foods, producing about 9 kilocalories of energy per gram, more than double that of sugar. Experts recommend that no more than 30% of the calories in our diet come from fat.
Cell membrane... i believe this to be the correct answer
If an ecosystem lost its producers, there would be no way for energy to move up the web and the ecosystem would most likely fail. Without these energy-capturing organisms, herbivores would get no energy or food. Without them, carnivores would get nothing as well. Because decomposers get energy from all three, they would also die out.
If only decomposers were removed, there would be a lack of nutrients in the soil for plants. This would result in the above (loss of energy, food, and other commodities).

The priority action for Darla to take is to apply pressure through the vaginal canal on the presenting parts. In which by these technique applying pressure over the vaginal canal on the presenting parts will help relieve pressure on the umbilical cord. In addition, umbilical cord prolapse happens when the umbilical cord moves toward out of the uterus with or before the offering part of the fetus. It is a comparatively infrequent circumstance and happens in less than 1% of the prenatal period.
The cell would have to take in and use more energy in order to break the covalent bonds.
The correct option is B
Hydrogen bonds :
are the chemical mechanism that governs the complementarity of the bases of DNA. This correspondence is unique thanks to the geometry of the hydrogen donor atoms and the acceptors that form the bases.
The (hydrophobic) bases are stacked inside the double helix of DNA; their plane is perpendicular to the axis of the double helix. The outside (phosphate and sugar) is hydrophilic.
The hydrogen bonds between the bases of one strand and the bases of the other strand keep the 2 strands united.
One purine on one strand necessarily binds to a pyrimidine on the other strand. As a corollary, the number of purine residues is equal to the number of pyrimidine residues.
* A binds to T (by 2 hydrogen bonds).
* G binds to C (via 3 hydrogen bonds: more stable bond: 5.5 kcal vs 3.5 kcal).
What part of the DNA strand do hydrogen bonds hold together?
hydrogen. Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups (both within each component and between components). Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.
