Answer:
t(n) = 3·5^(n-1)
Explanation:
The recursive formula describes a sequence in which each term is 5 times the one before it. This is a geometric sequence with common ratio 5 and a first term that is said to be 3.
As you know, the generic formula for a geometric sequence is ...
an = a1·r^(n-1)
For a1 = 3, r = 5, and a sequence named "t", this is ...
t(n) = 3·5^(n-1)
Answer:
Explanation:
Glucose is a sugar, highly soluble in water because it has lots of polar hydroxyl groups (-OH) which can form hydrogen-bonds with water molecules. These types of bonds are intermolecular forces which are present in other macromolecules like the DNA or proteins.
Cholesterol and triglycerids are lipids. These have long chains of hydrocarbons, which are non polar and therefore insoluble in water.
Blood is made of a solid and a liquid part. <u>The solid part contains cells</u>. <u>The liquid part (plasma), is made of water, salts, and proteins</u>. Glucose and cholesterol/triglycerids travel in the liquid part of the blood, in an aqueous environment. Because the lipids are not soluble, they need to travel with a carrier protein that keeps them protected from the surrounding water.
I would say fossilization
The more the people, the more pollutant they generate which will pollute the the water.
Marijuana
Marijuana is a psychoactive drug and it includes the dried leaves, seeds, stems and flowers, from the Cannabis sativa or Cannabis indica plant. Marijuana is a federal illegal drug and it contains tetrahydrocannabinol (THC); a compound that has intoxicating effects and other similar compounds. The use of marijuana during pregnancy can lead to damaging health consequences for both the mother and baby. Marijuana is associated with lower birth weight, and high risk of brain, and behavioral problems in babies.
