Explain the difference between potential and kinetic energy

Answers

Answer 1

Answer: Potential energy is still energy. Energy that is siting and not in motion.
Ex. car, something on a dresser or bookcase

Kinetic energy is the complete opposite. It is energy that is in motion, also active energy.

Answer 2

Answer:

Answer: Potential energy is still. Kinetic energy is energy in motion.

Explanation:

The nucleotide of a DNA is slightly different to that of RNA due to an addition of a hydroxyl (OH) on the sugar molecule on the RNA nucleotide located on position 2 of the nucleotide.

Further Explanation:

The DNA and RNA molecules are almost similar.

1. Nitrogenous bases

They both have a nitrogenous base on position one. The nitrogenous base can be one of the 5 bases Adenine, Cytosine, Guanine or Thymine which can be coded by their alternate Uracil in the right places. They are considered to be the building blocks of the DNA and RNA molecules.

2. Phosphate group

Located on position 5 of the nucleotide of both in RNA and DNA is the phosphate group. It has important functions including forming part of an ATP molecule to provide the body with the required energy. They also activate proteins through a process called phosphorilation for example in the cAMP cycle they activate protein kinases.

3. Ribose

On the second carbon position there is a ribose sugar. It has only one oxygen molecule linked to each one of the 5 carbon atoms. On the second carbon position, the oxygen molecule is bound to a hydrogen atom forming a hydroxyl (OH). It is only in the RNA that the ribose sugar exists giving it its name; Riboneucleic acid.

4. Deoxyribose

The prefix deoxy- means that lack of oxygen. That is where the name deoxyribonucleic acid (DNA) comes from. On the second carbon position of the nucleotide is where there is lack of the oxygen molecule that usually binds to the carbon and hydrogen molecules leaving a hydrogen only bound to the 2nd carbon position. This sugar is only found in the DNA molecule. This small lack of an oxygen bound to the hydrogen allows specific enzymes to be able to identify the difference between a DNA molecule and an RNA molecule.

Difference between the two, DNA and RNA, is that DNA comprises of deoxyribose sugar while RNA comprises of the ribose sugar.

Further Explanation:

DNA and RNA are known to be the most vital molecules in the field of cell biology and is responsible for storing as well as reading the genetic information which basically underpins all life. They are both known to be linear polymers comprising phosphates, sugars, and bases.

DNA or deoxyribonucleic acid and RNA or ribonucleic acid are basically polymers comprises of monomers which are called nucleotides. A molecule of RNA comprises of 5 carbon sugar-phosphate associated with one of the four nucleic acid bases, namely, cytosine, guanine, uracil, and adenine. RNA comprises of a ribose sugar, with the hydroxyl modifications. RNA comprises of only one strand and is also known to be shorter as compared to DNA molecule. As RNA comprises of a ribose sugar, it is known to be more reactive as compared to the molecule of DNA.

In a molecule of DNA, the sugar is lacking the hydroxyl group at the 2’ position and the thymine base is observed instead of uracil. DNA comprises of two strands and it is arranged in a double-helical structure. DNA is considered to be more stable as compared to the RNA molecule due to which, it is useful for the DNA molecule to carry the responsibility for storing the genetic information safely.

A characteristic representedby X is common to both of these processes.ActiveDiffusionXTransportA characteristic that the two processes have incommon is that each process(3) uses oxygen(1) uses ATP(2) requires enzymes(4) moves molecules

Answers

Answer: Move substances

Explanation:

The process of diffusion and active transport are some of the process inside the body which helps in transportation of the materials from one place to another.

The substances move a region of higher concentration to lower concentration in case of diffusion and with the help of energy the molecules moves from lower concentration to higher concentration.

The correct answer is option D.

diffusion doesnt required energy or atp enzyme, and oxygen. it just need different concentration between two substance and semipermeable membrane if it is diffusion in water that usually we call as a osmosis.

otherwise they both move molecules, certain molecules somtime in transport active

How is RNA different from DNA

Answers

DNA and RNA have completely different purposes in us. DNA stores and transfers genetic information (Eye and hair colour, skin colour, etc..). RNA codes amino acids and makes proteins. DNA is double stranded while RNA is single stranded. DNA uses adenine, thymine, cytosine, and guanine; while RNA uses adenine, cytosine, uracil, and guanine.

DNA is double stranded and RNA is single stranded.

Vancouver Island is off the west coast of Canada, north of Washington State. The island is divided by mountains, the Vancouver Island Range. Describe what the climate must be like on the west and east sides of the mountain range.

Answers

Answer:

Vancouver Island is divided in two by the chain of Vancouver Island Ranges that cover it in its entirety. The highest point of this chain is the Golden Hinde, 2,195 meters high. The island's climate is among the mildest in all of Canada. In summer, maximum temperatures reach 30 ° C. The west coast is one of the most humid places in North America and, apart from some areas of Chile, one of the most humid regions in the world along with the equatorial territories. In the towns of Tofino and Ucluelet the average annual rainfall is 3300mm.

The eastern coast, especially in the southern part, has a quasi-Mediterranean climate with the driest summer season, and maximum temperatures reaching 30 ° C and minimum in the winter of -7 ° C.

On the east side, the climate would be cold, and tundra like.
On the west side, the climate would be mild.
