Answer:
Enzymes are catalysts for chemical reactions in living things. Enzymes, like other catalysts, lower the activation energy and increase the rate of chemical reac- tions. ... This means that enzymes do not change the direction of a reaction— they just change the amount of time needed for equilibrium to be reached.

Answer:
Hurricanes will become more frequent and expand to new areas.
Explanation:
Global warming will rise sea temperatures worldwide. This means conditions for hurricanes will be met more often (they only form in higher than average sea temperatures). That means more hurricanes will form in the future. Also because of rising sea temperatures new areas will be effected by hurricanes as they will meet the threshold required for hurricanes to form.
I think the the side where no snow falls, I hope I helped, sorry if I am wrong!
Answer:
B. an electron and a proton
Explanation:
An element is a pure substance that cannot be broken down into any other substances because it consists of only one type of atom. Each element consist of three types of sub-atomic particles known as protons, neutrons, and electrons. Protons having a positive charge, neutrons a neutral charge, and electrons a negative charge. Both protons and neutrons are both the same size, but have opposite charges. Protons and electrons attract each other because opposite charges have a attraction to each other.
Therefore, Option 2: An electron and a proton, is correct.
Answer: 2A Sensorineural deafness
2B Sensory adaptation
2C Central deafness
2D Conductive deafness
Explanation: The human ear is divided into 3 parts:
- <u>Outer</u> <u>Ear</u>: auricle, ear canal and tympanic membrane;
- <u>Middle</u> <u>Ear</u>: eardrum, tympanic cavity and ossicles (malleus, incus and stapes);
- <u>Inner</u> <u>Ear</u>: oval window, semicircular ducts (attached to cochlea and nerves), cochlea and auditory tube;
The <u>Sensorineural</u> <u>deafness</u> is a type of deafness caused by a damage in the inner ear, either the cochlea or the auditory nerve. It can happen because of medicine toxicity, exposure to noise along the years etc.
So, from the scenarios above, 2A is consistent with sensorineural deafness since stereocilia are hair cells of inner ear.
<u>Sensory</u> <u>adaptation</u> is a phenomenom that happens when an individual's sensory receptors is exposed to a stimuli for a prolonged period of time. For example, the situation described in 2B. It is not considered deafness because it is not caused by a damage in any part of the ear.
<u>Central</u> <u>deafness</u> is a very rare case of deafness. The damage in this type of deafness is in the brain and not in any of the 3 parts of the ear. That's why the scenario in 2C is the example of this.
<u>Conductive</u> <u>deafness</u> is the second most common type of ear problem and it occurs in the outer ear. One of the causes is blockage in the ear canal by the ear wax, external bodies, osteomas (bone growth) or otitis (oute ear infection). An example of this type of deafness is scenario 2D.
