They teach us what happened in Earth before we arrived. For example, if we had never found any dinosaur fossils, we would have no idea what happened. Fossils show us ancient life and what it was like back then.

Fossils help scientists learn about and discover ancient lifeforms that have died and fosilised. They also may help us date other fossils and rocks that are hidden deep in the earth. finding similar fossils of animals on different continents helped support the continetal drift theory, which became the theory of plate tectonics!

"tertiary structure of a protein is maintained by (list the interactions)"
erik [133]

<span>Protein tertiary structures are known to be a three dimensional structure of a protein with a single polypeptide chain (backbone) and one or more protein secondary structures known as protein domains.</span>

Tertiary Structure Interactions

1) Hydrophobic Interactions: they are non- covalent bonds and very important in the formation of tertiary structure. 

2) Ionic Bonds: the interaction of both positive and negative amino acids forms a bond that helps to stabilize the protein molecules. 

3) Hydrogen Bonds: this bond exit between the amino acid with hydrophilic side chain found on the surface of the molecules and water molecules in a solution.

4) Disulfide Bridges: it is a strong covalent bond commonly found between cysteine residues in close proximity space.

Por que o nosso nariz fica entupido quando estamos resfriados?
Lubov Fominskaja [6]

why does our nose get stuffy when we have a cold

Answer:

Due to dilation of blood vessels in the sinuses of the nose

Explanation:

Often times, we think our nose gets stuffed up due to the excess mucus in times of cold but it is not always so.

We get stuffed due to the body's homeostasis, a drive to internally control and balance the outside environment.

  • During cold, blood vessels dilate so as to allow for more inflow of blood.
  • Incoming blood brings in more heat to the body parts.

Determine how tRNA is used when cells build proteins ...?
alexdok [17]
<span>tRNA carries a single amino acid to the ribosome. 
It fits the codon on the mRNA in the ribosome with it's anti-codon. 

The ribosome has peptidyl-transferase activity which catalyses the peptide bond between 2 amino acids on 2 tRNAs in the ribosome. 

One tRNA is released and then picks up another amino acid depending on its anti-codon.

The use of which material can substitute for copper and reduce copper mine production?
Lesechka [4]

Answer:

Glass

Explanation:

Copper is a good conductor of electricity and this is why it is used in electrical equipment to transmit electrons with the least resistance. Cable conductors are made of copper and used to transmit data. Copper is now being replaced by optic fiber that is made of glass. Instead of using electrons, fiber optic transmits data using photons – which transmits more data rate than copper.
