Frogs-have adapted to water and grow webbed feet to swim faster it helps it survive to move away from prey
porcupine- have adapted to being attacked so they have quills that will shoot out when being threatened
Fish-overtime have adapted and grown gills to breathe under water
Hope this help mark me brainliest please
Answer:
D) Water dissolves some molecules while causing the aggregation of others because of hydrophobic and hydrophilic interactions.
Explanation:
Sugars tend to dissolve, while lipids aggregate out because sugar has hydrophilic (water loving) interaction with water and on the other hand lipids have hydrophobic (fear of water) interaction with water. Water is a polar solvent and only polar solute dissolve in it due to phenomenon of like dissolve like, while lipids does not dissolve in it because lipid is non-polar in nature. In this case, sugar is hydrophilic while lipids is hydrophobic.
Most of the volume of the atom is empty space, throughout which tiny, negatively charged electrons are dispersed.
The nucleus is the center of the atom, around this the electrons move on different energy levels but, in the middle of that, there's only empty spaced.
Answer: b. causes the gastric glands to increase production of gastric juice.
Explanation:
The parasympathetic nerves are part of the autonomous nervous system. The parasympathetic predominates mainly during "passive responses" of the organism, such as satiety, rest and digestion. Its functions are: Promotes energy conservation, Reduces heart rate, Promotes glandular secretion, Protects the retina from excess light, Promotes emptying of cavities, Promotes rest and repair, Physiologically antagonizes sympathetic nervous system.
Answer:
Base
Explanation:
Deoxyribonucleic acid, DNA, is one of the four major biomolecules in living organisms. It is a polymer made up of monomers called NUCLEOTIDES. The nucleotides that make up a DNA molecule is composed of three substances namely: Sugar (deoxyribose), nitrogenous base, and a phosphate group.
However, among these three components of the nucleotide monomer, NITROGENOUS BASE is the only portion that is not the same in every DNA molecule. There are four nitrogenous bases in nature viz: Adenine, Guanine, Cytosine and Thymine. These four bases can be alternated in a DNA molecule.
Note that, phosphate group and deoxyribose sugar are constant in every DNA.
