FREE AP Biology Trivia Question and Answers
Chemicals emitted by creatures that cause other members of the same species to exhibit a physiological or behavioral response are referred to as
Explanation:
As sex attractants, alarm messages, or territorial markers, pheromones are used. Plant hormones called auxins encourage growth.
Mycorrhizae fungi help the calypso orchid, Calypso bulbosa, flourish in close proximity to them. The fungi get within the flower's roots and feed off the plant's nutrients. Rare minerals, including phosphates, are concentrated by the fungi in the roots where the orchid may easily reach them. This instance exemplifies
Explanation:
Mutualism is demonstrated here. Both creatures gain from this. A symbiotic relationship in which one organism gains and the other suffers is illustrated by parasitism. Commensalism is a situation in which one organism gains and the other is unaffected. The concept of endosymbiosis proposes that some organelles are descended from symbiotic prokaryotes that reside inside larger cells.
A decrease from +50 millivolts to -70 millivolts in a neuron's membrane potential is referred to as
Explanation:
Repolarization is a voltage change from +50 to -70. Depolarization can be avoided since it occurs when a voltage changes from -70 to +50. It is erroneous to refer to a voltage change from -70 to -90 as hyperpolarization. A moving depolarized wave known as an action potential can also be eliminated. Depolarization, repolarization, hyperpolarization, and resting potential are all included in the phrase.
Which of the following traits apply to both fungi and bacteria?
Explanation:
They both have a plasma membrane, a cell wall, and genetic material (DNA). Bacteria don't have a distinct nucleus like fungi do. Fungi are both unicellular and multicellular, in contrast to bacteria, which are single-celled.
Which of the following DOES NOT take place during DNA replication?
Explanation:
The enzyme that lengthens DNA strands is called DNA polymerase, not RNA polymerase. The double helix is unwound by DNA helicase. As complementary bases attach, DNA strands invariably extend in the 5' to 3' direction in the presence of DNA polymerase.
Which of the subsequent trypsin-related claims is FALSE?
Explanation:
Trypsin is an enzyme, which are organic catalyst made of proteins that hasten reactions without changing them. They do not become part of the process.
The sympathetic nervous system stimulates all of the following EXCEPT
Explanation:
Emergency conditions activate the sympathetic division. Your digestive system's peristalsis is reduced as a result. (You feel your gut tighten.) The sympathetic nervous system is stimulated, which causes perspiration, dilated pupils, and constricted peripheral blood vessels.
