<u>Answer:</u> This therapy is available for 15 days.
<u>Explanation:</u>
We are given:
Oral solution dosage = 75 mg/5 mL
To calculate the volume of oral situation for single dose per, we use unitary method:
The volume required for 75 mg of solution is 5 mL
So, the volume required for 300 mg of solution will be = 
The total volume of the ranitidine bottle = 300 mL
To calculate the number of days, we divide the total volume of the bottle by the volume of dose taken per night, we get:
Hence, this therapy is available for 15 days.
Answer:
Alkali metals
Explanation:
The alkali metals are a group of metallic elements which are present in the first group of the periodic table. In other words, they are present in group 1 of the periodic table. These elements have one electron in their valence shell, the reason why they are placed in group 1.
They ionize by losing one electron to achieve the configuration of the nearest Noble gas or inert gas. Because they need to offset only one electron in their outermost shell, they are very chemically reactive and hence rarely occur in the free state.
Examples of elements in this group include lithium, potassium and sodium. They each have one electron only in their outermost shells.
Both of the lizards have adapted by having their skin the same colour as their habitat so they could camouflage into the environment and not be spotted by predators.
the rabbit population would decrease as the rabbits would be unfamiliar with the new predators way of hunting so they wouldn't have adapted to be able to get away from the new predator
