Answer:

case1.

The addition of acid and base leads to a change in pH of the water when adding to deionized water due to fact that acid and bases dissociated in dissolving in water. If the H+ ion increases in the water as acid addition hikes it, it will result in decreasing the pH value. The intensity of the acid also affects the dissociation of the ions.

case2

Buffers are normally formed by weak acid and its conjugate base, and adding acid to the buffer it absorbs the H+ ions so the pH will be lower and adding base or increase of OH- conjugate base resists the pH value to increase.

SO2________________.
Mashcka [7]

Answer:

a. Dipole-dipole bonding

Explanation:

SO2 has dipole-dipole bonding. This is because of the difference in the electronegativities  of Sulphur and oxygen. Moreover, the lone pair of electrons on S gives it bent shape with a net dipole  unlike CO2 which has a linear shape.( This why CO2 does not have any dipole moment).

So, the correct answer is a.

What is the molecule that senses heat stress in a cell?
nlexa [21]

Answer: -

sigma factor mRNA RpoH sigma H sigma 32

Explanation: -

It is the heat shock sigma factor which activates due to heat. The factor will bind with to the polymerase-core-enzyme. After this other heat ans shock proteins are expressed.

This thus enable the cell to survive higher temperatures. Some of the enzymes that are expressed upon activation are chaperones, proteases and DNA-repair enzymes

The biosphere of the earth is made up of _______compounds.<br> A. Inorganic <br> B. Organic
KATRIN_1 [288]

Answer:

B.

Explanation:

When we say "biosphere", we're referring to the atmosphere, geosphere, lithosphere and hydrosphere, and everything in them. You've probably heard of these in class as the "pillars of Earth" or the "pillars of our planet". In other words, when we talk about biosphere we're talking about life.

Organic compounds are all of the compounds that contain carbon, C, in them. You might know that CHNOPS* are the "7 molecules of life", and you might have noticed that Carbon stands first in the list, and that's not because it makes up a mnemonic, Carbon is indeed the most important one in many ways.

*Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus and Sulfur.

Hope it helped,
