Prokaryotes are different from eukaryotes. Which of the following are missing in prokaryotes? (1 point)
a nucleus genetic material a cell membrane cytoplasm
The correct answer is a nucleus. Prokaryotes do not have a well-defined nucleus like eukaryotes do. Instead, their genetic material is present in the cytoplasm in the form of a single circular chromosome or in some cases, plasmids. They do have a cell membrane and cytoplasm.
During a specific part of the cell cycle, a cell will divide into two daughter cells. What is that process called? (1 point)
metaphase interphase G1 phase cell division
The process in which a cell divides into two daughter cells is called cell division.
DNA is a double- stranded molecule composed of a 5-carbon sugar, a nucleotide, and a phosphate group. What is the name of the 5-carbon sugar?
RNA is a single- stranded molecule composed of a 5-carbon sugar, a nucleotide, and a phosphate group. What is the name of the 5-carbon Sugar?
Answers:
ribose deoxyribose glucose fructose
The 5-carbon sugar in DNA is called deoxyribose.
The 5-carbon sugar in RNA is called ribose.
The movement of molecules from an area of greater/higher concentration to an area of lesser/lower concentration is called:
(1 point)
active transport osmosis diffusion homeostasis
The movement of molecules from an area of greater/higher concentration to an area of lesser/lower concentration is called diffusion.
Which organelle would you NOT expect to find in animal cells?
(1 point)
chloroplast
smooth endoplasmic reticulum ribosome
mitochondrion
The organelle that you would not expect to find in animal cells is the chloroplast. Chloroplasts are found in plant cells and are responsible for photosynthesis.
