user: Q: Females are not influenced by the male sex hormone testosterone during embryonic development because they lack what?   Read this paragraph and choose the correct option from the provided answers:  Unlike males, females are not influenced by the male sex hormone testosterone during embryonic development. This is because they lack a Y chromosome. As a result, females do not develop male reproductive organs. By the third month of fetal development, most of the internal female organs have formed. Immature eggs also form in the ovary before birth. Whereas a mature male produces sperm throughout his life, a female produces all the eggs she will ever make before birth.   Choices:  - x chromosome​  - m chromosome​  - z chromosome​  - y chromosome   A:
y chromosome

Q: How do the male gorillas show display behaviors?   Read this paragraph and choose the correct option from the provided answers:  In many species display behaviors, rather than actual physical attacks, are used to show aggression. This helps prevent injury and death. Male gorillas, for example, are more likely to put on a display of aggression than to attack another male. In fact, gorillas have a whole series of display behaviors that they use to show aggression. They beat on their chest, dash back and forth, and pound the ground with their hands.   Choices:  - food gathering  - vocalization  - spontaneous mutation  - showing aggression   A:
(Answer)
showing aggression


Ques: Q: What plays the same role in rotational motion that force plays in linear motion.   Read this paragraph and choose the correct option from the provided answers:  of pivot point, and so we choose the pivot point to simplify the solution of the problem. Second, the acceleration due to gravity canceled in this problem, and we were left with a ratio of masses. This will not always be the case. Always enter the correct forces—do not jump ahead to enter some ratio of masses. Third, the weight of each child is distributed over an area of the seesaw, yet we treated the weights as if each force were exerted at a single point. This is not an approximation—the distances r 1 and r 2 are the distances to points directly below the center of gravity of each child. As we shall see in the next section, the mass and weight of a system can act as if they are located at a single point. Finally, note that the concept of torque has an importance beyond static equilibrium. Torque plays the same role in rotational motion that force plays in linear motion. We will examine this in the next chapter. Take-Home Experiment Take a piece of modeling clay and put it on a table, then mash a cylinder down into it so that a ruler can balance on the round side of the cylinder while everything remains still. Put a penny 8 cm away from the pivot. Where would you need to put two pennies to balance? Three pennies?.   Choices:  - efficiency  - frame  - fulcrum  - torque   A:
Ans: torque

Q: During interphase, the cell undergoes normal growth processes while also preparing for what, by accumulating energy and building blocks of dna?   Read this paragraph and choose the correct option from the provided answers:  The population is an important unit in ecology as well as other biological sciences. How is a population defined, and what are the strengths and weaknesses of this definition? Are there some species that at certain times or places are not in populations?.   Choices:  - proteins division  - chromosome division  - technology division  - cell division   A:
(A).
cell division


Ques:Q: Although it is the easiest to observe, what property is not ideal as a sole way to identify minerals?   Read this paragraph and choose the correct option from the provided answers:  Color is probably the easiest property to observe. Unfortunately, you can rarely identify a mineral only by its color. Sometimes, different minerals are the same color. For example, you might find a mineral that is a golden color and think it is gold. But it might actually be pyrite, or “fool's gold,” which is made of iron and sulfide. It contains no gold atoms.   Choices:  - temperature  - density  - composition  - color   A:

Ans:color


Q: What kind of hormones are derived from cholesterol?   Read this paragraph and choose the correct option from the provided answers:  17.2 Hormones Hormones are derived from amino acids or lipids. Amine hormones originate from the amino acids tryptophan or tyrosine. Larger amino acid hormones include peptides and protein hormones. Steroid hormones are derived from cholesterol. Steroid hormones and thyroid hormone are lipid soluble. All other amino acid–derived hormones are water soluble. Hydrophobic hormones are able to diffuse through the membrane and interact with an intracellular receptor. In contrast, hydrophilic hormones must interact with cell membrane receptors. These are typically associated with a G protein, which becomes activated when the hormone binds the receptor. This initiates a signaling cascade that involves a second messenger, such as cyclic adenosine monophosphate (cAMP). Second messenger systems greatly amplify the hormone signal, creating a broader, more efficient, and faster response. Hormones are released upon stimulation that is of either chemical or neural origin. Regulation of hormone release is primarily achieved through negative feedback. Various stimuli may cause the release of hormones, but there are three major types. Humoral stimuli are changes in ion or nutrient levels in the blood. Hormonal stimuli are changes in hormone levels that initiate or inhibit the secretion of another hormone. Finally, a neural stimulus occurs when a nerve impulse prompts the secretion or inhibition of a hormone.   Choices:  - germs  - Antibiotic  - synthesis  - steroid   A:
