Explain the hypothesis that eukaryotes evolved from prokaryotes.
snow_lady [41]

Answer:

The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.

Explanation:  Both mitochondria and chloroplasts are similar to bacteria in size, and like bacteria, they reproduce by dividing in two. Most important, both mitochondria and chloroplasts contain their own DNA, which encodes some of their components. The mitochondrial and chloroplast DNAs are replicated each time the organelle divides, and the genes they encode are transcribed within the organelle and translated on organelle ribosomes. Mitochondria and chloroplasts thus contain their own genetic systems, which are distinct from the nuclear genome of the cell. Furthermore, the ribosomes and ribosomal RNAs of these organelles are more closely related to those of bacteria than to those encoded by the nuclear genomes of eukaryotes.

How is the molar heat of sublimation related to the molar heats of vaporization and fusion? On what law are these relationships
Dovator [93]

Answer: Hsub=Hfus+Hvap

Explanation:

The molar heat of vaporization measured in kilojoules per mole, or kJ/mol is the energy needed to make vapor one mole of a liquid. .

The molar heat of sublimation measured in kilojoules per mole, or kJ/mol is the energy needed to sublime one mole of a solid,

the molar heat of fusion measured in kilojoules per mole, or kJ/mol is the energy needed to melt one mole of a solid.

Hess law helps to explain the relationship in physical chemistry stating that the total enthalpy change during the complete course of a reaction is the same whether the reaction is made in one step or in several steps.

In this context Hess’s law helps to see the several steps involved as the heat of sublimation energy is equal to the sum of vaporization energy and fusion energy.

A student dissolves 4.5 G of sodium chloride into 75 grams of water which of the following statements is correct regarding the r
Jobisdone [24]
"The vapor pressure will decrease and the boiling temperature will increase." When sodium chloride is added to water, the vapor pressure above the resulting salt solution is less than the vapor pressure above the pure water, and the boiling point of the salt solution will be greater than the boiling point of pure water. This results from the introduction of salt molecules to water, in which the salt solution needs a higher temperature for the vapor pressure to be equal to the pressure of the atmosphere.
