Hypertonic solution: higher concentration outside of cell = lower water potential = water exits cell, cell shrink (crenated-animal cell, flaccid/plasmolysed-plant cell)

Hypotonic solution: lower concentration outside cell =higher water potential = water enters cell, cell swell (animal cell - burst,plant cell - turgid)

What is fusion and how does it relate to e=mc squared?

E = mc2 Meaning

At the beginning of the 20th century, the notion of mass underwent a radical revision. Mass lost its absoluteness. One of the striking results of Einstein’s theory of relativity is that mass and energy are equivalent and convertible one into the other. Equivalence of the mass and energy is described by Einstein’s famous formula E = mc2. In words, energy equals massmultiplied by the speed of light squared. Because the speed of light is a very large number, the formula implies that any small amount of matter contains a very large amount of energy. The mass of an object was seen to be equivalent to energy, to be interconvertible with energy, and to increase significantly at exceedingly high speeds near that of light. The total energy of an object was understood to comprise its rest mass as well as its increase of mass caused by increase in kinetic energy.

In special theory of relativity certain types of matter may be created or destroyed, but in all of these processes, the mass and energy associated with such matter remains unchanged in quantity. It was found the rest mass an atomic nucleus is measurably smaller than the sum of the rest masses of its constituent protons, neutrons and electrons. Mass was no longer considered unchangeable in the closed system. The difference is a measure of the nuclear binding energy which holds the nucleus together. According to the Einstein relationship (E = mc2) this binding energy is proportional to this mass difference and it is known as the mass defect.

Two groups of tomatoes were grown under laboratory conditions, one with humus added to the soil (Group 1) and the other a contro
charle [14.2K]

Answer:

the humus contains the minerals necessary for chlorophyll synthesis

Explanation:

<em>The yellowness of leaves in plants can be attributed to inadequate chlorophyll in the plant</em>. The chlorophyll is responsible for the greenness appearance of the leaves of plants and when it is present in inadequate quantity, the leaves appear yellowish in color.

<u>Some of the minerals necessary for the formation of chlorophyll include magnesium, nitrogen, and iron</u>. It thus means that the humus supplied to the soil of group 1 plant has the necessary minerals to synthesize chlorophyll while the soil of group 2 plants is deficient in some or all the minerals required for chlorophyll synthesis.

The front leg of a cat, the front flipper of a dolphin, and the wing of a bat have the same structure and order of bones. These
Kay [80]

Answer:

The bones are homologous structures

Explanation:

Homologous structures are the structure which are found similar in appearance in different organisms.

The homologous structures in different organism shows that they shared a common ancestor or they diverged from a common ancestor during course of evolution that is these homologous structures are the result of the divergent evolution.

In the given question, the bat, dolphin and the cat shows the same structure of bone which indicates that they have evolved from a common ancestor and is true as they all belong to mammals.

Thus, the bones are homologous structures is correct.
