Answer the following question given this paragraph: Cytokinins Promote cell division; prevent senescence. Q: Cytokinins promote cell division and prevent what? Choices: - deficiency - apoptosis - mutations - senescence A:
senescence
Answer the following question given this paragraph: hydrophilic heads are directed outward, in contact with the water. Each micelle may contain thousands of lipid molecules. Polar lipids may also form a monolayer, a layer one molecule thick on the surface of the water. The polar heads face into water, and the nonpolar tails stick up into the air. Bilayers are double layers of lipids arranged so that the hydrophobic tails are sandwiched between an inner surface and an outer surface consisting of hydrophilic heads. The hydrophilic heads are in contact with water on either side of the bilayer, whereas the tails, sequestered inside the bilayer, are prevented from having contact with the water. Bilayers like this make up every cell membrane (Figure 17.6 "Schematic Diagram of a Cell Membrane"). Figure 17.5 Spontaneously Formed Polar Lipid Structures in Water: Monolayer, Micelle, and Bilayer. Q: When something is described as "hydrophilic", you can determine something about how it interacts with what? Choices: - hydrogen - air - iron - water A:
water
Q: Answer the following question given this paragraph: A wobble base pair is a non-Watson Crick base pairing between two nucleotides in RNA molecules. The four main wobble base pairs are guanine-uracil, inocine-uracil, inosine-adenine, and inosine-cytosine. Wobble base pairs are fundamental in RNA secondary structure and are critical for the proper translation of the genetic code. Inosine is a nucleoside that is formed from the hydrolytic deamination of adenine. Structurally, it resembles guanine, but lacks the 2-amino group. This lack of the 2-amino group allows inosine to form base pairs with uracil, cytosine and adenine, making it a particularly wobbly base. Q: Of the four main wobble base pairs, guanine is paired with what? Choices: - thymine - cytosine - adenine - uracil A:
A: uracil
Question: Answer the following question given this paragraph: Q: What is the oxygen-storing protein found in diving mammals' muscles called? Choices: - pigment - hemoglobin - pheromone - myoglobin A:
Answer: myoglobin

Answer the following question given this paragraph: The cell wall is located outside the cell membrane. It consists mainly of cellulose and may also contain lignin, which makes it more rigid. The cell wall shapes, supports, and protects the cell. It prevents the cell from absorbing too much water and bursting. It also keeps large, damaging molecules out of the cell. Q: Where is the cell wall located? Choices: - in cell membrane - in the chloroplast - in the mitochondria - outside cell membrane A:
**Answer**
outside cell membrane

Answer the following question given this paragraph: 37.4 Regulation of Hormone Production Hormone levels are primarily controlled through negative feedback, in which rising levels of a hormone inhibit its further release. The three mechanisms of hormonal release are humoral stimuli, hormonal stimuli, and neural stimuli. Humoral stimuli refers to the control of hormonal release in response to changes in extracellular fluid levels or ion levels. Hormonal stimuli refers to the release of hormones in response to hormones released by other endocrine glands. Neural stimuli refers to the release of hormones in response to neural stimulation. Q: Regulation of hormone production hormone levels are primarily controlled through negative feedback, in which rising levels of a hormone inhibit its? Choices: - particular release - recent release - Limited release - further release A:
(A).
further release
