Enzymes can either help break a substrate molecule down to smaller ones or help substrate molecules join to form a larger one. They work as catalysts by reducing the activation energy of the reaction by providing an alternate pathway for it. The enzymes are specific with their substrates.
Answer:
When you see stars inside the eye, you may be experiencing what's called an entoptic phenomenon. ... They're actually little clumps of vitreous gel floating inside your eye. Sometimes they can be caused by other conditions, including: tears or holes on the retina...
The primary causes of blurred vision are refractive errors — nearsightedness, farsightedness and astigmatism — or presbyopia. ... Cloudy vision usually is a symptom of specific conditions such as cataracts. Blurry vision and cloudy vision both can be symptoms of a serious eye problem, especially if they occur suddenly.
Answer:
B. igneous rock
Explanation:
Igneous rock are the rocks which are formed due to the cooling of magma over the time.
There are majorly of two types
Intrusive igneous rocks : These are the rocks which are formed by the cooling of magma under the crust
Extrusive igneous rocks : These are the igneous rocks which are formed due to the cooling of magma on the crust of the Earth.
And app that has helped with every subject in school is Socratic (can you put this as brilliant answer I think that’s what is called)
First, let calculate the volume of the rod shaped-bacteria:
S = length of the bacteria * surface of its side = 4.1 * (0.45 *0.45 * 3.14) = 2.6 µm3
Now, let's convert the moles into molecules (with Avogadro's law):
0.0037mol/L = 0.0037 * 6.023 *10^23 = 2.22 *10^21 molecules / L
Now let's convert The volume and the concetrnation into µm3 (molecules / µm3)
1 L = 1 dm3 = 1000 cm3 = 1000000 mm3 = 10^9 µm3
so 2.22 *10^21 molecules / L = 2.22 10^ 12 molecules / µm3
The answer is 2.22 10^ 12 molecules / µm3
