Mutations can occur before, during, and after mitosis and meiosis. If a mutation occurs in cells that will make gametes by meiosis or during meiosis itself, it can be passed on to offspring and contribute to genetic variability of the population

Question 1 (2 points)
Blababa [14]

The amino acids coded triplets in the 3' to 5' strand on the normalp53 gene of chromosome 13 are lysine, leucine, Glutamine, stop codons.

Explanation:

mRNA is formed by the transcription of DNA strand coding for  a gene.

Any mutation in the DNA sequence even a difference of base pair would cause formation of different amino acids and hence altered protein.

The amino acid is formed in the step of translation where codes are read by tRNA on the mRNA strand and correct nucleotide is brought to growing polypeptide chain.

In transcription 3' to 5'  strand acts a template strand. The amino acids on the p53 gene of chromosome 17 is

3'TTT AAC   GTC    ATC 5'    Gene sequence

5' AAA UUG CAG   UAG 3'   mRNA

lysine, leucine, Glutamine, stop

Which of the following is NOT part of the peripheral nervous system?
Ksju [112]

The correct answer is: B. spinal cord  

The nervous system can be divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The spinal cord and the brain are part of the CNS, whereas the PNS consists of the nerves that radiate from the CNS to all parts of the body. The PNS includes all neurons that sense and transmit information to the CNS.

The CNS controls thinking processes, movements, and registers the sensations throughout our body. Moreover, the PNS acts to transmit information from the CNS to all parts of the body.

The PNS is in turn divided into two main parts:

1-The Autonomic nervous system (ANS), which regulates involuntary functions and glands. The parasympathetic nervous system is one division of the ANS that controls visceral organs such as glands.

2- Somatic nervous system (SNS), which regulates voluntary muscle movement and transmits information from eyes, ears, and skin to the CNS.

Choose any one of the consumer services companies and write an essay of about 500 words on how a diverse economy such as the Uni
zaharov [31]

Answer:

let's take the example of Walmart, which has the large presence in the United States and is an important part of the Consumer Services Industry.

Explanation:

Walmart began with just one store but has grown all over the country to many unique aspects of the American economy and demographics. The United States, in contrast to what many people assume, is a very diverse country.

The culture of New England is very different from that of the Bible belt. Similarly, the African American culture of Georgia is different from the casual California where there is a vast Hispanic population.

Walmart saw an opportunity in this diversity and has grown by catering to needs of all these consumers. Communities with highly dense Hispanic population stocked food items that were very different than can be found in Jewish neighbourhoods and vice verse.

This enabled Walmart to connect with each community and grow with them over the generations.

In all this, Walmart prides itself in providing benefits to US army veterans and provides jobs to women from low-income backgrounds and the disabled.

In all this, Walmart does face a number of different challenges, including:

A slowing economy can hit the profits of the company

Competition from other companies such as Costco and even international players like Aldi and Lidl can decrease their market share

Online rivals such as Amazon have long been identified as a threat to the company and is one of the biggest challenges facing the consumer service industry.

Companies like Amazon are not only involved in retail but also in selling movies, music, etc that can completely challenge the consumer service sector
