Rashid [163]

Answer: 1, 2, 4 are accurate.

Explanation:

1. Joe is on a hill (on a trail) above the ocean. The beach and ocean are at similar altitudes. Therefore Joe is at a higher altitude than if he was at the beach.

2. Since Joe is on a hill, he has a higher altitude than at sea level. Air at a higher altitude has lower density because there is less air "ontop" of itself than at lower altitudes. As well, his hill is above the ocean, which means there is a lot of water, making the air more humid than where he is. Humidity also makes air denser.

4.The air pressure will decrease if Joe goes up to higher altitudes because there will be less air on top of itself.

Katen [24]

two steps of expression of a gene in their correct chronological order are Transcription then translation.(option a)

The process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce protein or non-coding RNA end products and ultimately affect a phenotype as the final effect is known as gene expression.

It comprises two significant stages: translation and transcription, Gene expression is made up of transcription and translation working together to form a polypeptide.

  • The production of RNA from DNA is known as transcription. The enzyme RNA polymerase acts as the catalytic agent.
  • The process by which a messenger RNA's genetic code is decoded to produce a particular polypeptide chain is known as translation. A particular amino acid is specified in each genetic code.
