HELP PLZ
Answer:
I believe it would be B.) Quick drop in dissolved oxygen
Quick drop in dissolved oxygen is a possible consequence of solid pollutants in a lake or river.
What is Biological Oxygen Demand?
Biochemical oxygen demand (BOD) is the amount of oxygen consumed by bacteria and other microorganisms while they decompose organic matter under aerobic conditions.
Solid pollutants in freshwater bodies like river and lake generally corresponds to organic wastes such as leaves, flowers and clothes which lead to increase in number of microorganisms in these water that further results in increase of BOD.
Drastic increase in microorganisms lead to drop in amount of dissolved oxygen in water, thus the possible consequence of solid pollutants in a lake or river is quick drop in dissolved oxygen.

what is the process that breaks down nucleic acids into nucleotides
a. dehydration synthesis
b. synthesis
c. polymerization
d. hydrolysis
please help ty
Answer:
D. Hydrolysis
Explanation:
Dehydration synthesis reactions build molecules up and generally require energy, while hydrolysis reactions break molecules down and generally release energy. Carbohydrates, proteins, and nucleic acids are built up and broken down via these types of reactions, although the monomers involved are different in each case.
I hope this helps have a great day :)
The process that breaks down nucleic acids into nucleotides is hydrolysis. The correct option is d.
What is hydrolysis?Any chemical reaction in which a water molecule breaks one or more chemical bonds is known as hydrolysis.
When water is the nucleophile, the phrase is used generically to refer to substitution, elimination, and solvation processes.
Nucleo depolymerase is another name for nuclease. By cleaving the phosphodiester bond that connects the nucleotides in the nucleic acids, the nucleic acid is broken down into nucleotides.
Either an enzyme or a non-enzyme can cleave the nucleic acid chain. Since the initial step in the alkaline hydrolysis of a polynucleotide is the transfer of the bond from C5' of the subsequent nucleotide to C2' of the same nucleotide, a 2'-OH group is necessary.
Thus, the correct option is d.

How do we know that the ocean is continually absorbing carbon from the atmosphere, helping with climate stability?
O Increased carbon in the oceans have made them more acidic.
O Ocean pH has increased significantly in the last decade.
O There are bubbles like carbonation on the ocean surface.
O Fish we catch and eat from the ocean are made of carbon.
The concentration of carbon is increased in the oceans have made them more acidic.
Increased carbon concentration in the oceans which have made the ocean water more acidic is the indication that more carbon is absorbed by the ocean. When carbon absorbed by the ocean, the carbon reacts with water which produced carbonic acid.
This carbonic acid decrease the pH of the ocean water that adversely affect the marine organisms especially coral reefs. When the pH of the ocean water increases, bleaching of coral reef occurs because the algae living on them die so we can conclude that the concentration of carbon is increased in the oceans have made them more acidic.

John and Marissa purchase their first home for $120,000. They must put 15 percent down on the purchase price as a down payment. What will the amount of the down payment be?
Answer:
Downpayment: 15% of original price
Original price: $120,000
15% of 120,000 = [tex]\frac{15}{100}[/tex] × 120,000
= $18,000
Thus, the downpayment is $18,000.
John and Marissa purchase their first home for $120,000 than the Down payment is 15% of original price
Original price: $120,000
15% of 120,000 = × 12 = $18,000
Thus, the downpayment is $18,000.
What is down payment?Part A
The down payment of $48,000 is 20% of the purchase price
Part B
A $12,000 down payment will be 5% of the purchase price
A percentage is the expression of the product of the ratio of two numbers and 100
The amount the investors buy the studio apartment = $240,000
The amount the investors have as down payment = $48,000
Part A
The ratio of the down payment the investors have and the amount the investors buy the apartment = 45,000/240,00 = 0.2
Therefore, their down payment is 0.2×100 = 20% percentage of their purchase price
Their $48,000 down payment is 20% of their purchase price
Part B
The percentage of the purchase price a $12,000 down payment would be is given as follows;
12,000/240,000 × 100 = 5%
Therefore, a $12,000 down payment will be 5% of the purchase price.

The basic idea of the occupation is that information scientists invent new computing technologies in response to various needs. Invention naturally leads to technological advancements in many different lines of work.
As a metal, lithium will lose electrons to have a ful valence shell. How manyvalence electrons will it lose to have full valence shell? What will be the charge of the lithium ion?
please help me
Answer:
It will lose 1 electron
Its charge will be 1+, or simply (+)
Explanation:
Lithium it's located in the group one of the periodic table, the Alkali, and by rule, all Alkali are always gonna loose one electron during a chemical reaction to form a positive ion.
The charge is explained by the fact that, if lithium looses one electron, then it wi have less number of electrons than protons, meaning that, if there's a higher number of protons (positive charge), then the charge will be positive. And since the atom loosed one electron then its charge will be 1+
For example, during a chemical reaction calcium is always gonna loose 2 electrons, so its charge's gonna be Ca2+
