Chromatography is a simple technique in principle, it remains the most important method for the separation of mixtures into its components. It is quite versatile for it can be used to separate mixtures of solids.
Explanation:
- The two elements of chromatography are the stationary phase and the mobile phase. There are many choices of stationary phases, some being alumina, silica, and even paper. The mobile phase, in liquid chromatography, can also vary. It is often either a solvent or a mixture of solvents and is often referred to as the eluant.
- A careful choice of eluting solvent helps to make the separation more successful. The mixture is placed on the stationary phase. The eluant passes over the mixture and continues to pass through the stationary phase carrying along the components of the mixture.
- Chromatography is used in industrial processes to purify chemicals, test for trace amounts of substances, separate chiral compounds and test products for quality control. Chromatography is the physical process by which complex mixtures are separated or analyzed.
- Chromatography is based on the principle where molecules in mixture applied onto the surface or into the solid, and fluid stationary phase (stable phase) is separating from each other while moving with the aid of a mobile phase
<span>If we put a Rhoeo leaf in plain water, the water concentration of the leaf cells will be higher than that of the plain water. The aim is to balance water concentration on the inside and outside of the organism. So, the water will exit the leaf cells, which will consequently shrink in size. The most of the cells will shrink in size, causing the leaf to shrink, too.</span>
The plant is classified as a Monocot.
Monocotyledons have only one cotyledon in the embryo. Its leaf veins are parallel. Its petals are in the multiples of three. It has a fibrous root pattern. It does not have a secondary growth. It does not have a cortex and its stem and vascular system is composed of bundles of vascular tissue scattered all throughout the stem without any specific arrangement.
The correct answer is - increased competition.
If an ecosystem experiences an increase in its biodiversity, than the result of it would be increased competition. The increased competition will be for food sources, water sources, territory. The reason why increased competition will occur is that there are only limited mounts of food sources, water sources, and territory in the ecosystem. There's also certain amount of niches in the ecosystem, and once all of them are occupied by some species, any other that is specialized for that niche will be competitor plus. This increased competition will lead to high evolutionary pressure, which will result in relatively quick adaptations and specialization in order to survive.
