A biology student views several different prokaryotic and eukaryotic cells under a microscope. How do the prokaryotic cells appear different from the eukaryotic cells?
A
Eukaryotic cells have ribosomes and prokaryotic cells do not.
B
The prokaryotic cells are smaller than the eukaryotic cells.
C
The prokaryotic cells have mitochondria.
D
The eukaryotic cells have cytosol.

B. The prokaryotic cells are smaller than the eukaryotic cells.

Explanation: Its just the simple process of elimination. Prokaryotic cells lack of a lot of things, including mitochondria, so it couldn't be option C. BOTH prokaryotic and eukaryotic cells have cytosol AND ribosomes, so the answer couldn't be D or A, and you're left with option B. Meaning option B is the correct choice.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
