WHY IS A FOSSIL FOUND IN MULTIPLE LAYERS OF ROCK (TIME PERIODS) NOT CONSIDERED A RELIABLE INDEX FOSSIL?

Answers

Answer 1

Certain fossils, called index fossils, help geologists match rock layers. To be useful as an index fossil, a fossil must be widely distributed and represent a type of organism that existed for a brief time period. Index fossils are useful because they tell the relative ages of the rock layers in which they occur.

Once assembled, what is the key to a protein's unique function?​

Answers

Answer:

Once assembled, what is the key to a protein's unique function? The manner in which proteins fold is the key to their function

The endoplasmic reticulum is an important  region where protein folding occur. Because proteins need to be appropriately folded into distinct structures, this is an essential biological function.

What is importance of protein folding?

Proteins that are misfolded or are unfolded improperly impart to the pathophysiology of many illnesses.

Protein folding is a highly delicate process that is regulated by a variety of external stimuli, such as temperature, pH, chemicals, molecule crowding, electric and magnetic fields, and temperature.

These elements affect a protein's capacity to fold into the appropriate functional forms.

Therefore, Protein folding give unique properties to protein functions.

Joe is experimenting to determine which liquid will cause bean plants to grow faster. He watered the plants with equal amounts of liquid and measured their height every other day. The plants are in the same pots with different soils and placed in the same location. Will Joe be able to obtain reliable data to write a supported conclusion?
Yes, because he is only observing the height of the plant.
Yes, because he is consistent with watering the plants.
No, because he used different soils.
No, because he uses only one type of plant.

Molecules of DNA are composed of long chains of?

Answers

two long polynucleotide chains

A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together

Molecules of DNA are composed of long chains of nucleotides.

What are nucleotides?

Nucleotides are the building blocks of DNA  and RNA adenine (A), thymine (T), guanosine (G), and Cytosine (C. In RNA, uracil (U) is present instead of thymine.

The pentose sugar is the ribose sugar in RNA and deoxyribose sugar in DNA. In deoxyribose sugar, oxygen is absent from the 3' carbon.

Phosphate groups are attached through the 5-C of pentose sugar by an ester bond. One polynucleotide chain is formed when the phosphate of one nucleotide forms a phosphodiester bond with the sugar of another nucleotide.

A double-stranded structure is formed by base pairing between nucleotides. The adenine binds to thymine by two hydrogen bonds and guanine binds to cytosine by three hydrogen bonds.

Therefore the molecules of DNA are composed of long chains of nucleotides.
