What shape is the sugar in a nucleotide?

Answers

Answer 1

Answer:

In double-stranded DNA, the molecular double-helix shape is formed by two linear sugar-phosphate backbones that run opposite each other and twist together in a helical shape. The sugar-phosphate backbone is negatively charged and hydrophilic, which allows the DNA backbone to form bonds with water.

The structure labeled "A" open and close the sites where the gases, carbon dioxide and oxygen, are exchanged during photosynthesis. What is the structure labeled A?

Answers

The structure A in the question seems missing but the given answer is based on the description given in the question.

Answer:

The gaseous exchange of carbon dioxide(CO2) and oxygen(O2) occurs through small, regulated openings called stomata during photosynthesis.

Therefore the Structure A is Stomata

A scientist is extracting the DNA of a multicellular organism. He finds that 20% of the strands bases are Thymine. Based on Chargaff's rule, what percentage of the
strands bases would be Adenine?

A. 20%
B. 70%
C. 40%
D. 60%

Answers

Answer:

A. 20%

Explanation:

A DNA molecule consists of four nucleotides viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). According to Chargaff in his complementary base pairing rule, these nucleotides pair with one another in such a way that A bonds to T, while G bonds to C.

Based on Chargaff's rule, the amount of Adenine in the DNA is equal to the amount of Thymine while the amount of Guanine is equal to that of Cytosine i.e. A=T, G=C.

A + T + G + C = 100%

Hence, in this question, a scientist finds that 20% of the strands bases are Thymine. This means that the amount of Thymine in that DNA will also be 20%. S

Since A=T = 20% in accordance to Chargaff rule.

1. How much force accelerate a bicycle and rider with mass 60 kg at 1.5 m/s?

Answers

Answer:

Force, F = 90 N

Explanation:

Given that,

Mass of the bicycle and rider, m = 60 kg

Acceleration of the bicycle and rider, a = 1.5 m/s²

We need to find the force acting on the bicycle and rider to accelerate. Let it is F. Its force is given by :

F = ma

F = 60 kg × 1.5 m/s²

F = 90 N

So, the force acting on the bicycle and rider is 90 N.

A cell’s nucleus will divide during mitosis. Whaat process must happened before it can divide?

Answers

Prokaryotic cells, which include bacteria, undergo a type of cell division known as binary fission. This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. The outcome of binary fission is two new cells that are identical to the original cell.

Calculate the volume in mL of a stock solution of 100% ethanol, required to prepare 2 L of a 70% solution of ethanol in dH2O

Answers

Answer:

For example, to make 70% ethanol from 95% ethanol, take 70 mL of 95% ethanol and add enough water to bring the volume to 95 mL. You will then have 95 mL of 70% ethanol. This works for any dilution and all that is required is a large enough graduated cylinder.

When using liquid reagents, the percent concentration is based upon volume per volume, i.e. #ml/100ml. Example 2: If one wished to make a 70% ethanol solution, 70 ml of 100% ethanol would be dissolved in 30 ml of water (or the equivalent for whatever volume was needed).

How does water cause frost wedging?

A
Water attracts lightning, which breaks apart huge boulders into many smaller pieces.

B
Water carries sediment to large rocks, causing them to rub against each other.

C
Water freezes and thaws inside rock cracks, causing them to widen and then split.

D
Water slowly wears down a rock’s sharp edges, leaving behind a smooth surface.

Answers

Answer:

C. Water freezes and thaws inside rock cracks, causing them to widen and then split.

Explanation:

When water gets in the crack at the bottom and freezes, frost wedging occurs.

Frost wedging happens when water gets in crack, freezes, and expands. This process breaks rocks apart. When this process is repeated, cracks in rocks get bigger and bigger (see diagram below) and may fracture, or break, the rock.
