Exchange of anything with blood (air, nutrient, hormones etc) occurs through blood capillaries. This is thanks to the simple squamous epithelium lining the walls of the capillaries.
Answer:
It will take 83 days to recover the extra cost
Explanation:
To determine the length of time it will take to recover the extra cost, it will be logical that we compare the $200 extra cost to the total savings in running cost made for a year and covert this into days
The total savings in running cost is the cost savings per hour multiplied by the number of hours in a year.
The calculations are set below:
Savings in running cost per hour = $0.1
Total savings in a year = 365 days × $0.1 × 24 = $876
Extra cost of Energy Star refrigerator = $200
If total savings for a year is $876 , then equivalent length of time to save $200 would be
Length of time = 200/876 × 365 days = 83 days
It will take 83 days to recover the extra cost

Answer:
Covalent
Explanation:
Covalent bonds are bonds where two atoms share electrons. The chlorine atoms will share one electron so they both have a full valence shell, which makes the bond between them covalent.
Answer:
Nerve impulse
Explanation:
A nerve impulse is transmitted through the synaptic cleft by acetylcholine. When an impulse reaches the synaptic knob, it stimulates the vesicles to move towards the presynaptic membrane releasing the acetylcholine. The transmitter substance makes the membrane permeable. An action potential is then formed along the neuron.
