Answer:

C. Beginning of autumn

Explanation:

On this image we can see the position of the Earth toward the Sun in four different parts of the year. WE can see that in one part of the year the Northern Hemisphere is tilted toward the Sun, while in the opposite part of the year it is the Southern Hemisphere that is tilted toward the Sun. In between them, we have 21 March and 23 September when both hemispheres are equally exposed to the sunlight. These to dates mark the beginning of spring and beginning of autumn. As they are dates when both hemispheres receive equal amounts of sunlight, it means that these are the dates when the equinoxes appear on Earth.

How does succession occur after a forest fire
fredd [130]
Secondary succession occurs when a natural devastating calamity or event takes place such as hurricane and forest fire. It is often faster compared to primary succession because there are available resources already including soil, roots, seeds and other vegetative organs from plants can be found underground.

The pKa for the side chain of histidine is 6.0. What is the ratio of the deprotonated imidazole side chain to the protonated sid
Solnce55 [7]

Answer:

When the pKa is 6.0, we can determine the fraction of protonated H is by:

pH = pKa + log [A]/[HA]

Where

A = Deprotonated imidazole side

HA = Protonated side

Given, pH = 5.0

5 = 6 + log [A]/[HA]

log [A]/[HA] = -1 (take antilog of both side)

[A]/[HA] = 0.1

The ratio of the deprotonated imidazole side chain to the protonated side chain at pH 5.0 = 0.1

Given, pH = 7.5

7.5 = 6 + log [A]/[HA]

log [A]/[HA] = 1.5 (take antilog of both sides)

[A]/[HA] = 31.62

The ratio of the deprotonated imidazole side chain to the protonated side chain at pH 5.0 = 31.62
