Tiny organisms known as cyanobacteria, or blue-green algae.
<span> First you need to know how many isotopes there are of silicon, and its average atomic units (look at periodic table). Then make up a system of equations to solve for it. Theres 3 stable silicon isotopes (28, 29, 30) so you will need to have 3 equations. You must be given the percent abundance of at least one of the isotopes to solve because here I can only see 2 equations (numbered down below) set x = percent abundance of si-28 y = percent abundance of si-29 z = percent abundance of si-30 since all of silicon atoms account for 100% of all silicon: x + y + z = 100% = 1 therefore: 1) x = 1 - y - z You also have 2) 28x + 29y + 30z = average atomic mass you can substitute x so that equation becomes: 28 (1 - y - z) + 29y + 30z = average atomic mass See how you have 2 variables here? You cant go on until you know the value of one isotope already or you have given a clue which you can derive the third equation</span>
Answer:
Once three protons have entered the matrix space, there is enough energy in the ATP synthase complex to synthesize one ATP. In this way, the energy in the hydrogen ion gradient is used to make ATP. ... The mitochondrial hydrogen ion gradient is generated as electrons pass through three membrane complexes.
The functions of the ears are:
I. Hearing by collecting and processing sound waves
II. Keeping our balance when we turn or bend over; option A
<h3>What is the function of the ear?</h3>
The ear is one of the five sense organs in the body.
The sense organs are the organs which receive external stimulus and send it to the brain for processing and response.
The other sense organs are:
- the eye
- the nose
- the skin
- the tongue
The functions of the ear are for hearing and for balance.
In conclusion, the sense organs function to receive stimulus and send them to the brain.
