differences between the structure of the wall of the stomach and the structure of the wall of the ileum​

Answers

Answer:

Wall of stomach : it has three layers of muscle instead of two. Under these muscle layers is the adventitia, layers of connective tissue continuous with the omenta. The epithelium of the stomach forms deep pits, called fundic or oxyntic glands.

wall of ileum : The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface. The ileum has an extremely large surface area both for the adsorption of enzyme molecules and for the absorption of products of digestion.

a. dehydration synthesis
b. synthesis
c. polymerization
d. hydrolysis
please help ty

Answers

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.

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?

Answers

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.

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 down payment is $18,000.

HELP PLZ

Answers

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.

Answers

Answer:

A.TRANSPIRATION

Explanation:

Trees have deeper roots than other plants, which implies they can access and pump up larger soil water volumes for transport to the leaves for transpiration and growth. ... The energy needed to evaporate all that water is withdrawn from the environment and leaves the system as embedded latent heat.

Which means if the forest got messed up the transpiration would be jacked up

which microscope would be best to look at the wings of two different butterflies to determine which is a monarch butterfly and which is a viceroy butterfly?

Answers

SEM microscope should be

To determine the difference between a monarch butterfly and a viceroy butterfly, it would be best to use a microscope that has high magnification and resolution, such as a compound light microscope or an electron microscope.

What is a microscope?

A microscope is an optical instrument that is used to magnify small objects or details, such as cells or tissues, so that they can be studied or observed more closely. There are various types of microscopes available, including compound light microscopes, scanning electron microscopes, and transmission electron microscopes, which use different principles to produce magnified images of the objects being examined.

A compound light microscope would allow you to see the structures of the wings in detail, while an electron microscope would provide even higher resolution images, but would require the wings to be coated in a thin layer of gold or other metal in order to be viewed. Both of these types of microscopes would allow you to see the fine details of the wings and compare them to determine which is a monarch butterfly and which is a viceroy butterfly.
