A controlled atmosphere is a system where food technicians control and manage the volume of oxygen and carbon dioxide in an environment. It is an important step in production processes and quality.
Food technicians are professionals involved in the production processes of foods and product quality.
These professionals (food technicians) maintain devices and equipment used during food control processes.
A controlled atmosphere is an important process for maintaining proper conditions for many foods.

Answer:
The pelvic bones of whales are “one of the classic examples of a vestigial structure,” said Otárola-Castillo. “But what we found was that the shapes of these bones are highly associated with the mating systems of these whales and dolphins — species that are more promiscuous have more-complex-shaped pelves.”
No it will not. Since the mutation is towards the end of the codon, it is very likely that it would not change the amino acid at all.
Answer: C
Explanation: Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.
Example 1:
Endoplasmic reticulum (ER) are like factories of cells. If we consider cell as a international clothing chain of companies, then ER are the ones which plan and design the clothing, sew those up, put additional buttons etc. on them, and then ship them on time. The workers (manual and automatic) do the whole procedure.
To understand it better in terms of cellular functions, ER create biomolecules essential for cells and the body as a whole. ribosomes are the workers which do the synthesis. With the help of ribosomes, ER makes the whole process of biomolecule synthesis, modification and delivery smooth, efficient and accurate.
Example 2:
Think of ER as Uber Eats. It provides you the catalogue of delicious food available and can be sent, then forwards your request to the restaurant, then sends a delivery person to wait and collect the order, and then orders the person to delivery food to the correct address on time.
Here, ribosomes would be the restaurants making the food.
**This is a simplification of the actual function of ER but I hope you get the gist. While talking about smooth and rough ER, the examples may change.
