Answers

The amount of guanine in a organism always equals the amount of cytosine.

What is guanine and cytosine in a DNA molecule?

The Deoxyribonucleic acid (DNA) molecule is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).

The guanine, also called guanosine, is defined as one of the nucleobases found in the nucleic acid of DNA and ribonucleic acids (RNA).

Cytosine plays an essential role in forming base pairs by bonding with guanine and forming the genetic code found in both DNA and RNA.

Therefore,the quantity ofguanine bases are the same with cytosine bases on the opposite strand.

Cytosine. This is because Guanine ALWAYS bonds with Cytosine in DNA

the compound that is used for energy reserve, insulation, an to repel water is the- a)carbohydrate b)protein c)lipid d) nucleic acid

Answers

C) lipids.
LIPIDS – lipids are commonly called fats, oils, waxes, phospholipids, and steroids. Lipids contain large amounts of energy, most of which is stored in your body like an energy reserve. Lipids contain three elements: carbon, hydrogen, and oxygen (very little oxygen, however). Fats and oils are used as energy storage and insulation; waxes repel water (like the waxy cutin on leaves, and the peel of an apple); phospholipids are a big structural chemical, making up a large portion of the cell membrane; and steroids are units of structure and help control functions. Fats are made up of building blocks as well; a fat is made up of 3 fatty acids and 1 glycerol.

Using the explicit formula, calculate how far the students will be swimming on week 10 using Ernest's schedule.

Answers

Ernest would be swimming at 3.25 units on week 10

The explicit formula is given as:

a_n = a_1 + (n - 1) * d

Also, we have the following parameters

a_1 =1.0 -- the initial distance

d =0.25 --- the difference between concurrent distances

In week 10, the value of n is 10.

Next, substitute 10 for n in the explicit formula a_n = a_1 + (n - 1) * d

So, we have:

a_(10) = 1.0 + (10 - 1) * 0.25

Subtract 1 from 10

a_(10) = 1.0 + 9 * 0.25

Multiply 9 by 0.25

a_(10) = 1.0 + 2.25

Add 1.0 and 2.25

a_(10) = 3.25

Hence, Ernest would be swimming at 3.25 units on week 10

Three separate longitudinal ribbons of smooth muscle on the outer surfaces of the colon are known as __________.

Answers

Answer:

he Taeniae coil

Explanation:

The mesocolic,free and omental taeniae are collectively known as TAENIAE.

They are the 3 ribbon of smooth muscle of the ascending,transverse, descending and the sigmoid  colon. Anatomically their longitudinal   contractions give the natural bulges(HAUSTRAL) in the colon.

The Haustral helps in translocation of chyme to the next haustral, and  aiding the mixing of chyme for water absorption in the colon,  

The coil of these  smooth muscles is under the parasympathetic nervous system through Sacral nerve (of the spinal cord)  innervation.
