Answer:
Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration. Anaerobic respiration evolved prior to aerobic respiration.
The answer is 44 chickens and 28 rabbits.
We have a system of two equations.
x - the number of rabbits
y - the number of chickens
Both chicken and rabbit have only 1 head, so the first equation is: x + y = 72.
Since rabbits have 4 legs and chickens 2 legs, the second equation is: 4x + 2y = 200.
Now, let's solve the system:
x + y = 72
4x + 2y = 200
___________
y = 72 - x
⇒ 4x + 2 · (72 - x) = 200
4x + 2 · 72 - 2 · x = 200
4x + 144 - 2x = 200
2x + 144 = 200
2x = 200 - 144
2x = 56
⇒ x = 56 ÷ 2 = 28
So, there are 28 rabbits.
Since
y = 72 - x = 72 - 28 = 44,
there are 44 chickens.
That is where the fibers of the optic nerve exit the eye extending into the brain. there are no rods and cones there as a result.
the answer ito this is rainfall
Answer: Eye drops are effective when it placed into the eyes with care and proper instructions.
Eye drops should be placed in the lower conjunctival sac that starts at the inner side of the eye not the outer side called as canthus.
If the eye drops are dropeed on the cornea of the eyes and this causes discomfort and hence should be avoided.
It should not be placed on the opening of the lacrimal ducts otherwise it will avoid the systemic absorption.
