The incorrect one is b. different enzymes has a different optimum temperature.
Answer;
-Endoplasmic reticulum
Explanation;
Molecules produced in the nucleus are transported to the cytoplasm via endoplasmic reticulum.
-Endoplasmic reticulum (ER) is a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins.
It is an interconnected network of flattened sacs or tubes encased in membranes. These membranes are continuous, joining with the outer membrane of the nuclear membrane. It works closely with the Golgi apparatus, ribosomes, mRNA, and tRNA.
The right option is; d. 366 people/mi^2
Population density is a measure of the number of people that constitute the population in a particular area per square kilometer or square mile.
From the question, the population of China is; 1,355,935,022, and the land area is; 3,705,405 mi^2.
Population Density = Number of People / Land Area.
Population Density =1,355,935,022/ 3,705,405 = 365.93 = 366 people/mi^2.
Therefore, the population density of China is 366 people per square mile.
