Random changes in allele frequency in a population are called:gene flow

genetic drift

microevolution

stabilizing selection

Answers

Random changes in allele frequency in a population are usually called genetic drift. The reason why this is the answer is because it is a very specific word which is used to describe exactly that - random changes in allele frequency. 

All the other cases; answers, here aren't correct and don't apply. 

Final answer:

Genetic drift is the random changes in allele frequency in a population.

Explanation:

Random changes in allele frequency in a population are called genetic drift. Genetic drift refers to the random fluctuations in the frequencies of alleles in a population, caused by random sampling effects. It is one of the mechanisms of microevolution, which refers to the changes in allele frequencies within a population over time. It is different from gene flow and stabilizing selection, which are also mechanisms of microevolution.

The general who directed the project responsible for the "Fat Man” graduated from what alma mater in 1918?

Answers

Answer;

-The name of the general was Leslie Richard Groves Jr. He Graduated fourth in his class in the U.S. Military Academy at West point.

Explanation;

  • The name of the general was Leslie Richard Groves Jr. He graduated from the United States Military Academy of West point in the year 1918.
  • As an engineering aide, He led a small team of workers who helped produce the exterior casing of "Fat Man," a nuclear bomb dropped on Nagasaki, Japan, that hastened the Japanese unconditional surrender three weeks later.

Leslie Richard Groves Jr. is the right answer.

He was the general who conducted the project accountable for the "Fat Man”. He became graduated in the year 1918, from the United States Military Academy of West Point. He directed as a small group of engineers who build the outer casing of "Fat Man," an atomic bomb released on Nagasaki, Japan, that urged the Japanese absolute submission in the next three weeks.

During which process is mRNA converted into a sequence of amino acids for protein production?transcription

translation

translocation

mRNA synthesis

Answers

B. Translation

Translation is the process whereby Messenger RNA is decoded in a ribosome and uses its information to build chain of amino acids or polypeptide. Furthermore, specific amino acids that are carried by tRNAs are chain together into a polypeptide as the mRNA passes through ribosome. However, there are three stages or phases in translation which includes: Initiation, Elongation and Termination.

Answer:

The correct answer would be translation.

Translation is the process by which nucleotide sequence of mRNA (messenger ribonuceic acid) is converted into the amino acid sequence of the polypeptide chain.

Ribosome serves as the site of translation in a cell.

The process of translation can be divided into three phases:

Initiation: The small and large sub-units of the ribosome sandwiched the mRNA around the start codon and provide the sites (A, P, and E site) for tRNA (transfer RNA)-mRNA interaction.

Elongation: The charged tRNA (tRNA carrying amino acid) enters at the A site. The anti-codon site present in tRNA helps in decoding the codon sequence present in mRNA.

The tRNA then adds specific amino acid to the growing polypeptide chain in P site. It then leaves from E site.

The ribosome then moves (translocates) to the next codon and the cycle repeats itself and add amino acid to the polypeptide chain.

Termination: As soon as ribosome reaches the stop codon it releases the polypeptide chain and dissociates from the mRNA.

The polypeptide chain then undergoes post-translation changes to mature into functional protein.

B. Tan was always immensely proud of her mother's unique way of communicating in the English language, which is why she chose to discuss her mom in the book.
C. Tan was embarrassed by her mother's language variety, and Tan was ashamed that she also lapsed into broken English at times.
D. Tan was neutral about her mother's language variety, but she chose to speak proper English that she learned at school.
Tan was initially proud of her mother's language variety, but she began to dislike it when she noticed how others reacted to it.

Answers

The correct answer is B. Tan was proud of her mother who had a unique way of communicating in English language that is why in her book she chooses to discuss about her mother.

Tan and her mother they had a close relationship because,

1. Tan's mother used to attend tans lectures.

2. Her mother trusts and relies on her to talk to doctors about the scan of CAT.
