If given a chance to advice Mr. Smith, I would recommend him to minimize going out in the sun when it is at the peak of the morning but if not possible since he works under the sun, it would be good to put on sunblock with a highest SPF and use precautionary measures like using hats and wearing long sleeve to protect also the skin.  More water to hydrate, and vitamins for skin protection.

4. A polypeptide has the following amino acid sequence: Met-Ser-Pro-Arg-Leu-Glu-Gly In the mutant below, indicate the type of mu
MatroZZZ [7]

Answer:

4. c. Deletion/ frameshift mutation

5. a. Tyr Tyr Asp Ser Gly

6. A frameshift occurred which altered the identity of the amino acids following the initiator 6. methionine, but not the length of protein Q.

Explanation:

4)

A single base pair at the first position of the Arg codon i.e. CGA has been deleted. Due to the deletion, the reading frame has shifted one nucleotide backwards, altering the amino acid sequence of the protein.

5)

The genomic DNA sequence is 5'-ATG ATA CTA AGG CCC-3'. Therefore, the complementary mRNA will be 5'-UAC UAU GAU UCC GGG-3'. According to the genetic code, this mRNA sequence encodes the following amino acid sequence: Tyr Tyr Asp Ser Gly

6)

The wild type DNA sequence is:

5'-ACUGUAAUGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'

The mutant i.e. mRNA with the added G will be

5' ACUGUAAUGGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'  

This is a single base pair insertion and frameshift mutation that shifts the reading frame one base pair forwards. The codon that was originally GAG coding for glutamic acid (Glu) gets converted to GGA that codes for glycine. Therefore, the amino acid sequence has been altered but the polypeptide chain will still have 13 amino acids.

Hypothesize one way that a diploid organism could have offspring that are 3n or 4n
gladu [14]
Diploid refers to a cell that has two copies of each chromosome. One way that a diploid organism could have an offspring that are 3n (triploid) or 4n is when the chromosomes don't separate during meiosis.

Triploid refers to some cell that have 3 copies of each chromosomes for a total of 69 chromosomes.

A bond of the following elements would be of what type? Ca + 2Cl<br><br> Covalent or ionic
dedylja [7]

Answer:

Ionic

Explanation:

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.  

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

calcium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for calcium is 1. There is large difference is present. That's why electron from calcium is transfer to the chlorine. calcium becomes positive and chlorine becomes negative ion.

There are two valance electrons in calcium so it needed to lose two valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus two electrons lost by one calcium atom are gained by two atoms of chlorine.

Ca + Cl₂ → CaCl₂

Helga [31]

Answer:

<em>Jansky Very Large Array </em>

Explanation:

It Is most powerful telescope on Earth and  is located on the plains of San Agustin near Socorro, New Mexico, US. This telescope consist of 25 antennas whose collective ares is equal to a single 430 foot antenna. The angular resolution is equal to an antenna of 22 miles in diameter.  It is also possible to adjust its arms to change its resolutions. There is receiver in each antenna that can operate from wavelength range of 4 mm to 7 metres. National Radio Astronomy Observatory is in charge of this telescope.
