Answer the following question given this paragraph: All musical instruments create sound by causing matter to vibrate. Most musical instruments use resonance to amplify sound waves and make sounds louder. Most musical instruments also have a way of changing the frequency of sound waves, which changes the pitch of the sounds. Q: Changing the frequency of sound waves, will change the _________ of the sound of a musical instrument? Choices: - velocity - distance - direction - pitch A:
(Answer)
pitch
Ques: Answer the following question given this paragraph: In birds, 90% to 95% of species are monogamous , meaning the male and female remain together for breeding for a few years or until one mate dies. Birds of all types, from parrots to eagles and falcons, are monogamous. Usually, the parents take turns incubating the eggs. Birds usually incubate their eggs after the last one has been laid. In polygamous species, where there is more than one mate, one parent does all of the incubating. The wild turkey is an example of a polygamous bird. Q: Most bird species display this behavior, meaning the male and female remain together for breeding for a few years or until one mate dies? Choices: - dichotomy - polygamy - isolation - monogamy A:
Ans: monogamy

Ques:Answer the following question given this paragraph: The Brain The brain is the part of the central nervous system that is contained in the cranial cavity of the skull. It includes the cerebral cortex, limbic system, basal ganglia, thalamus, hypothalamus, cerebellum, brainstem, and retinas. The outermost part of the brain is a thick piece of nervous system tissue called the cerebral cortex. The cerebral cortex, limbic system, and basal ganglia make up the two cerebral hemispheres. A thick fiber bundle called the corpus callosum (corpus = "body"; callosum = "tough") connects the two hemispheres. Although there are some brain functions that are localized more to one hemisphere than the other, the functions of the two hemispheres are largely redundant. In fact, sometimes (very rarely) an entire hemisphere is removed to treat severe epilepsy. While patients do suffer some deficits following the surgery, they can have surprisingly few problems, especially when the surgery is performed on children who have very immature nervous systems. In other surgeries to treat severe epilepsy, the corpus callosum is cut instead of removing an entire hemisphere. This causes a condition called split-brain, which gives insights into unique functions of the two hemispheres. For example, when an. Q: What connects the two hemispheres of the brain? Choices: - The brain stem - holy callosum - disruption callosum - corpus callosum A:

Ans:corpus callosum
Ques: Answer the following question given this paragraph: When you get your cholesterol tested, they are measuring not only the total amount of cholesterol in the blood, but also whether it is being transported by LDL or HDL. All of these values are important for assessing the likelihood of a heart attack. Total cholesterol gives an idea of the overall cholesterol load in the body. The LDL cholesterol (sometimes referred to as "bad" cholesterol) is more likely to be incorporated into a cell or a plaque, so it is important that these levels below. Conversely, since cholesterol being carried by HDL ("good" cholesterol) is being transported away from the rest of the body and into the liver for disposal, higher HDL levels are generally considered beneficial. Q: What type of cholesterol is commonly referred to as bad? Choices: - unsaturated - hdl - insulin - ldl A:
Ans:
ldl
