Answer:

Mobile phones communicate bytransmitting radio waves through a network of fixed antennas called base stations. Radiofrequency waves are electromagnetic fields, and unlike ionizing radiation such as X-rays or gamma rays, can neither break chemical bonds nor cause ionization in the human body.

If the DNA nucleotides read 3'-ATG-CGT-GAC-5', the amino acid sequence of the resulting polypeptide
Marat540 [252]

Answer:

5’ – TAC-GCA-CTG-3’

Explanation:

As per the Chargaff’s complementary base pairing rule purine always pairs with a pyrimidine.  

Purines include adenine (A) and cytosine (C)

Pyrimidine include thymine (T) and guanine (G)

Thus an A always pair with T and C always pair with G

Thus, the resulting poly peptide for the given amino acid sequence is  

3'-ATG-CGT-GAC-5'

5’ – TAC-GCA-CTG-3’

A population of animals is split in half by a river. Before speciation is completed, the two halves are rejoined when a drought
natka813 [3]

This could impact the population by gene flow that would increase between the two halves, and speciation would not occur.

<h3>What is Speciation?</h3>

Speciation may be defined as the process of formation of new species from a parental one. It occurs when members of similar populations no longer interbreed to produce fertile offspring within their natural environment.

The complete question is as follows:

  • Traits that had developed through mutation would still exist in only one of the halves.
  • Speciation would still occur because the two halves would be too different genetically to interbreed.
  • The two halves would be reproductively isolated.
  • Gene flow would increase between the two halves, and speciation would not occur.

Speciation requires time for genetic variations and mutations to occur. It makes the organism's reproductive isolated and hence the process of speciation may take place.

Therefore, the correct option for this question is D.

What factors might influence how effective a vaccine is when it’s widely released?
AlekseyPX

Answer:

A vaccine basically works by injecting a small amount of a virus into your body, and your body learns to fight the virus and becomes immune to the virus.

Explanation:

If it is 100% safe and effective, I will take the vaccine. The vaccine is stored at 2-8 degrees celcius. It can stay in the refrigerator for 72 countinuous hours.  172 countries are working on a vaccine. 5 are the US, China, Brazil, Italy, and Japan. The name of the vaccine is COVAX. Two doses are required, and it should be mandatory for high risk people as well as everyone else.
