Biological molecules such as proteins and DNA reveal differences between humans and chimps that would have taken around 7 million years to accumulate.

<h3>What is DNA?</h3>

All known animals and viruses have genetic information in the form of deoxyribonucleic acid, a polymer consisting of two polynucleotide chains that coil around one another to form a double helix. Ribonucleic acid is a type of nucleic acid, as is DNA.

The two DNA strands are known as polynucleotides because they are constructed from simpler monomeric units called nucleotides.

The four nucleobases that contain nitrogen—cytosine (C), guanine (G), adenine (A), or thymine (T)—along with deoxyribose and a phosphate group—make up each nucleotide. The sugar of one nucleotide and the phosphate of the following make covalent bonds, creating what is known as the phospho-diester linkage, which results in an alternating sugar-phosphate backbone.

Does a moving magnetic field creat a megnetic field
faust18 [17]

Answer:

Explanation:

A moving charge causes a magnetic field and a moving magnet causes an electric field. If you change your frame of reference to that of the charged particle, the magnetic field disappears. Same is true for the magnet. Changing your reference frame to that of the magnet will make the electric field disappear.

Which kingdom contains heterotrophs with cell walls of chitin?
kirza4 [7]

It would not be plants, even though it has cell walls. They are not made of chitin. Plants are also not heterotrophic.

Fungi, however, decompose other matter, and have cell walls made of chitin. This would fit the description.

Korvikt [17]

Answer:

The water potentials (Ψ) of the cell and its surroundings are the same.

Explanation:

When a cell is kept in hypotonic surroundings such as distilled water, the osmotic movement of water occurs towards the cell. The entry of water makes the cell swell up and it becomes turgid. Water potential is determined by solute and pressure potentials mainly. Here, the solute potential of the cell and the distilled water was different resulting in differences in their respective water potential values which in turn served as a driving force for endosmosis.

When the cell is fully turgid, the solute concentration of the cell and the surrounding distilled water become equal to each other. Under these conditions, the water potential of the cell and distilled water are the same.

Delvig [45]

Answer:Long term drought, change of season from winter to summer, forest fire are unfavorable environmental factors which can deplete the amount of resources already available with the ecosystem.
