Question 1 0/1 pts (Q001) What is the difference between a prokaryote and a eukaryote? Correct Answer Prokaryotes lack a nucleus and are often one-celled organisms. Eukaryotes lack a nucleus and are often one-celled organisms. Prokaryotes contain a nucleus and are often multicellular organisms. You Answered Eukaryotes contain a nucleus and are often one-celled organisms. FEEDBACK: Prokaryotes lack a nucleus and are often one-celled organisms, whereas eukaryotes contain a nucleus and are often multicellular organisms. Question 2 1/1 pts (Q002) Which of the following cell parts produces energy for the cell and has its own DNA? nucleus cytoplasm cell membrane Correct! mitochondria https://ilearn.laccd.edu/courses/267723/quizzes/2151164?module_item_id=17591557 1/4

3/25/24, 7:18 PM LAB 02 CONCEPT REVIEW QUESTIONS: ANTHRO 111 : Lab Human Bio Evol - Rigby J. - SPRING 2024 - SECTION# 17489 FEEDBACK: Mitochondria produce energy for the cell and have their own DNA (not nucleus, cytoplasm, or cell membrane). Question 3 Not yet graded / 1 pts (Q003) What do the two members of a homologous chromosome pair have in common? Your Answer: The chromosomes in a homologous pair each have the same genes in the same order, but there may be variation between them, resulting in different alleles. Some of the variants in these alleles might have functional implications while others will not. Question 4 1/1 pts (Q004) Following the rules of complementary base pairing, which of these DNA bases could successfully bond with adenine? Correct! thymine guanine adenine cytosine FEEDBACK: Thymine is the DNA base that successfully pairs with adenine (not guanine, adenine, or cytosine). Question 5 1/1 pts (QO005) Following the rules of complementary base paring, which of these RNA bases could successfully bond with adenine? thymine Correct! uracil cytosine adenine FEEDBACK: Uracil is the RNA base that successfully pairs with adenine (not thymine, adenine or cytosine). https://ilearn.laccd.edu/courses/267723/quizzes/2151164?module_item_id=17591557 2/4

Question 7 1/1 pts (Q007) Mitosis occurs in which type of cell? Correct! somatic cells gamete-forming cells FEEDBACK: Somatic cells are where mitosis occurs. Question 8 1/1 pts (Q008) Meiosis occurs in which type of cell? somatic cells Correct! gamete-forming cells FEEDBACK: Gamete-forming cells are where meiosis occurs. Question 9 1/1 pts (Q009) The genetic information that moves from the nucleus to the cytoplasm of a cell during protein synthesis is called mDNA tRNA Correct! MRNA https://ilearn.laccd.edu/courses/267723/quizzes/2151164?module_item_id=17591557 3/4
