DNA is housed in the nucleus in eukaryotes. DNA is coiled around histone proteins and condensed into chromosomes. The ends of chromosomes are called telomeres. Chromosomes are joined at a place called the centromere.
Answer: Determines the properties of a mineral by the composition and structure .In such as: : colour, taste, tenacity, magnetism, fracture, streak, specific gravity, [ amount of transparency and crystalline structure.
It can be observed from their compositions that methyl orange is a polar compound because of the existence of -SO3Na functional group. The -SO3Na group is ionic in nature and imparts polarity to methyl orange. While biphenyl is a non-polar compound because of the non-existence of polar functional groups in its composition.
The silica gel chromatography refers to an apparatus, which is used to distinguish molecules on the basis of their polarity variations. The silica gel, that is, a stationary phase is polar in nature, and thus, the non-polar compounds seem to elute prior to the polar ones.
In the mentioned case, the biphenyl will elute first because of its non-polar characteristic and thus will exhibit high Rf value.
Answer:
The bees fly from flower to flower in search of nectar, which they transform into food, which benefits these insects.
On the other hand, whenever the bees are placed on a flower, particles of pollen adhere to their body; Such particles are transported to other flowers, resulting in plant pollination.
Explanation:
Mutualism is based on a version of the labor theory of value which it uses as its basis for determining economic value. According to mutualist theory, when a worker sells the product of their labor, they ought to receive money, goods, or services in exchange that are equal in economic value, embodying "the amount of labor necessary to produce an article of exactly similar and equal utility"
The physical force exerted by a fluid on a structure is HYDROSTATIC PRESSURE . The main pressure is the BLOOD hydrostatic pressure, which pushes materials OUT OF the capillary. The other main force regulating filtration and reabsorption is OSMOTIC PRESSURE , which refers to the "pull" of water into an area by osmosis due to the HIGHER relative concentration of solutes.
