For each of the following features of nucleic acids, indicate whether it is true of DNA only, of RNA only, of both DNA and RNA,
suter [353]

Answer:

Nucleic acid is one of the four major macromolecules that is present in all life forms. It includes DNA ( deoxyribonucleic acid) and RNA (ribonucleic acid). It is made up of small unit called nucleotides.

A nucleotide contains a pentose sugar that is deoxyribose in DNA and ribose in RNA, nitrogenous base that is Adenine, Thymine, Cytosine, Guanine in DNA and Adenine, Uracil, Cytosine, Guanine in RNA, and a phosphate group.

It is synthesised by a process of comlementary base pairing ( such as in double stranded DNA, A pairs with T and G pairs with C).

DNA is converted to mRNA inside the nucleus of eukaryotic cell and mRNA is then translated to protein when it moves the cytosplasm of the cell.

Thus, the correct answers are as follows-

1) Is an inherently directional molecule, with an N-Terminus on one end and a C-Terminus on the other end - true neither for RNA or DNA.

2) Contains the base adenine- True for both DNA and RNA.

3) Contains the nucleotide deoxythmidine monophosphate- True for DNA

4) Occurs only in signle stranded form- True for both RNA and DNA( such as single stranded DNA in DNA virus, and RNA in single stranded RNA in AIDS virus).

5) Is synthesized by a process that involves base pairing- True for both DNA and RNA.

6) Is involved in the process of protein synthesis in the cytoplasm of the cells in the liver- True for RNA ( particularly messenger RNA, mRNA)

Calculate the angle of impact for a blood droplet whose width is 6.8 mm and length is 7.2 mm.
PIT_PIT [208]

Answer:

71°

Explanation:

To obtain the angle of impact :

The length of blood stain = hypotenus

The width = opposite

Hence,

Hypotenus = 7.2 mm ; Opposite = 6.8mm

Angle of impact, θ = sin^-1(opposite /hypotenus)

θ = sin^-1(6.8/7.2)

θ = 70.8°

θ = 71°

How do the heart and lungs work together
MrRa [10]
Heart and lungs works hand in hand. Not only that they are close to each other but they also work to make sure that body gets enough oxygen that it needs to live. It is the heart that pumps blood through the body it passes through the lungs. then it is the job of the lungs to supply oxygen together with the blood that heart pumps.
