Question Which statement best describes viral reproduction?(1 point) Responses Viruses may contain DNA or RNA. Viruses may contain DNA or RNA. The lysogenic phase of viral replication causes cell death while the lytic phase of viral replication results in prophage formation. The lysogenic phase of viral replication causes cell death while the lytic phase of viral replication results in prophage formation. Viruses reproduce independent of cell based organisms. Viruses reproduce independent of cell based organisms. Viral nucleic acid is inserted into a host cell where it may replicate immediately or become dormant until a later time.
Viral nucleic acid is inserted into a host cell where it may replicate immediately or become dormant until a later time.
Question Which of the following is the equation for cellular respiration?(1 point) Responses 6 CO2 + 6 H2O → 6 O2 + 6 ATP 6 CO 2 + 6 H 2 O → 6 O 2 + 6 ATP 6 CO2 + 6 H2O + light → 6 O2 + 6 C6H12O6 6 CO 2 + 6 H 2 O + light → 6 O 2 + 6 C 6 H 12 O 6 6 C6H12O6 + 6 O2 → 6 H2O + 6 CO2 + ATP 6 C 6 H 12 O 6 + 6 O 2 → 6 H 2 O + 6 CO 2 + ATP 6 CO2 + 6 ADP + light → 6 O2 + 6 H2O
The correct equation for cellular respiration is: 6 C6H12O6 + 6 O2 -> 6 H2O + 6 CO2 + ATP
Which of the following statements describes active transport?(1 point) Responses Spontaneous movement of a substance through a semipermeable membrane. Spontaneous movement of a substance through a semipermeable membrane. Net movement of a substance from a region of higher concentration to a region of lower concentration Net movement of a substance from a region of higher concentration to a region of lower concentration Movement of a specific substance across a membrane. Movement of a specific substance across a membrane. [Movement of a substance against a concentration gradient. D]
Movement of a substance against a concentration gradient.
Which of the following describes how lysogenic virsuses are different from lytic viruses.(1 point) Responses Lysogenic viruses only infect plant cells and lytic viruses only infect animal cells. Lysogenic viruses only infect plant cells and lytic viruses only infect animal cells. Lysogenic viruses do not cause the host cell to burst right away and lytic virsuses do immediately cause the host cell to burst. Lysogenic viruses do not cause the host cell to burst right away and lytic virsuses do immediately cause the host cell to burst. Lysogenic viruses are cellular and lytic viruses are not. Lysogenic viruses are cellular and lytic viruses are not. Lysogenic viruses are made of DNA. Lytic viruses are made of RNA
Lysogenic viruses do not cause the host cell to burst right away, while lytic viruses immediately cause the host cell to burst.
