Vector components of an elephant are more complex than those of a penny. An elephant is not a projectile, while a penny is. They both have an acceleration of 9. The elephant is greater in mass but is slowed less by the effects of air resistance.
More massive objects will only free-fall faster than smaller objects if there is a significant amount of air resistance present. For a penny and an elephant that are free-falling in a vacuum, the rate of acceleration would be the same, so both would fall at the acceleration due to gravity which is 9. Which train described below would have the greatest momentum? The momentum of an object is equal to the mass of the object times the velocity of the object.
A scientist found that when an invasive species was introduced into a river, the population of salmon native to the region decreased. The type of correlation between these two populations could best be described as. When one factor affects a second factor, it can be said that the two have a strong correlation. Since the salmon population decreases as the invasive species population increases, these two factors have an inverse relationship.
The addition of a catalyst to a chemical reaction will have what effect? Increase the energy required for the reaction to take place. Increase the time required for the reaction to take place. Increase the rate at which the reaction takes place. Reduce the amount of products in the reaction.
A catalyst, by definition, is an enzyme that helps decrease the energy necessary to begin a reaction. Consequently, the addition of a catalyst to a chemical reaction will increase the rate at which the reaction takes place.
A reduction in the energy required to begin the reaction means that the reaction will take place more quickly. The pharynx is part of what body system? The pharynx is part of two systems; the respiratory and the digestive. It is another name for the throat, which extends from the base of the skull to the level of the sixth cervical vertebra.
Which of the following is true about eukaryotic cells? Unlike prokaryotic cells, eukaryotic cells contain mitochrondria, a nucleus, lysosomes, and multiple chromosomes.
What characteristic of an element determines its specific isotope? The number of neutrons is what gives the element its specific isotope. The number of protons determines which element it is, while the number of electrons determines if the atomic particle has a positive, negative, or neutral charge.
Which of the following scenarios would NOT give a normal distribution? A distribution of the yearly income of families in the U. The distribution of heights in a large sample of people. The percentage of toxic wastes and pollution in the atmosphere vs.
It is likely that as the percentage of toxic substances in an environment increases, the percentage of living organisms will decrease. This would be an inverse relationship and would not exhibit a normal distribution. The rest would show normal distribution. In a cell, the Golgi apparatus is found in what location? The Golgi body, or simply the Golgi, is an organelle found inside the cytoplasm inside a cell. While it is close to other organelles, it is positioned independently on its own within the cytoplasm.
Which taxonomic rank is the next-smallest after Order? The taxonomy ranks run from largest to smallest: The next-smallest after Order is Family. Cytokinesis happens after telophase and it is the splitting of one cell into two. In plants it involves the formation of a cell plate whereas in animals it involves the formation of a cleavage furrow.
The information in DNA is stored as four nucleotides: The nucleotides adenine and guanine are classified as purines, while thymine and cytosine are classified as pyrmidines. Purines contain 2 carbon nitrogen ring bases and pyrimidines contain 1 carbon nitrogen base. Which is NOT one of the four basic types of tissue?
The parenchyma of an organ consists of that tissue which conducts the specific function of the organ and comprises the bulk of the organ. It is not one of the four basic types of tissue: Which of the following correctly completes the sentence above? The stomach is above the small intestine. To calculate the atomic mass, we must sum the number of protons and the number of neutrons inside of the nucleus.
So, adding 42 protons with 37 neutrons results in an atomic mass of A patient who has suffered head trauma is not able to recognize people he has met around an hour earlier but is still able to recognize people he met before the injury. He most likely has damage to the: The hippocampus is the site of memory storage. The medulla oblongata is involved in involuntary controls, the corpus callosum is involved in connections between the two lobes and in emotions and the Pituitary gland is an endocrine organ..
What process is illustrated in the diagram above? Meiosis is a two-step process, and the four cells that result each have half the normal genetic material of the original cell.
Of the following, which is not a type of chemical bond? Ionic bonds involve the donation of and acceptance of electrons. Covalent bonds involve sharing electrons. Polar bonds describe electronegativity differences. Magnetic bonds are not chemical bonds. If the amount of hydrogen in a balloon of fixed size is doubled, what happens to the mass and density of the balloon?
The mass increases, but the density decreases. The mass decreases, but the density increases. As the number of molecules of air increases in a given volume, the mass of air also increases. As the mass of air in the given volume increases, its density also increases. For a chemical reaction to be balanced, the amount of reactants must be the same as the amount of products.
As there are 24 total carbons in the reactants, there should also be 24 carbons in the products. The graph above records the death rate of two types of male flies a certain number of days after a chemical pesticide is sprayed. What is the probability a male methuselah fly will be alive 75 days after exposure to the pesticide? A scientist wants to write an equation using the variables X, Y, and Z. What is the proper relationship between the variables if X represents time, Y represents energy, and Z represents power?
Power is equal to energy divided by time. What type of correlation is presented between price and quality? Although the correlation is not strong, it appears that the price increases as the quality increases. This describes a weak direct correlation. What type of cells result from mitosis? Mitosis produces two diploid daughter cells that have the same genetic material as the original mother cell. Cheetahs, rainbow trout, and inchworms belong to the same.
All three animals belong to the same kingdom of Animalia, but are too different to be classed in the same phylum. Cheetahs and rainbow trout are in the Chordata phylum, while inchworms are in Arthropoda phylum. The presence of which hormone would NOT cause an increase in water retention? ANP, or Atrial Natiuretic Peptide is a hormone released in response to increased blood volume and pressure that produces vasodilation.
As a consequence of this vasodilation, the excretion of both sodium and water increases in order to return to the homeostatic conditions prior to increased blood volume and pressure. Because excretion of water increases, ANP causes a decrease in water retention and not an increase. In which part of the heart does oxygenated blood flow out of? Oxygenated blood that leaves the heart is pumped from the left ventricle. Which of the following hormones are secreted directly by the hypothalamus?
Dopamine is a neurotransmitter in the brain that plays vital roles in a variety of different behaviors. Which of the following terms do these diagrams NOT portray? The first one is active transport as it requires ATP and the other two are symporter and antiporter respectfully. They both require facilitated transport. The only one not shown is an ion channel which requires no energy besides a gradient and is not active transport as it uses no ATP.

Tablets or capsules containing simethicone can also help alleviate symptoms of excess gas. Smoking has been linked to bloating, heartburn , and other digestive problems.
Fortunately, bloating is rarely a symptom of serious trouble. For most people, the most effective prescription for bloating is simple: These sensible remedies should keep you from feeling overstuffed and bloated.
Digestive Disorders Feature Stories. Keep Bloating at Bay Here are three common causes of bloating, and how you can avoid them. Overeating is probably the most common cause of bloating. Smaller portions should ease the pain.
Eating rich and fatty food can make you feel uncomfortably stuffed. Fat takes longer to digest than protein or carbohydrates, so it keeps the stomach full longer. Avoid bloating by limiting fats in your everyday diet. Eating too fast adds to the risk of bloating after a meal. Satiety signals can take up to 20 minutes to reach the brain and dampen appetite. Many weight loss experts believe that eating slowly helps prevent overeating. Reducing Gassiness The second most common cause of temporary bloating is gas in the abdomen.
Avoid Bloat-Inducing Foods Difficult-to-digest foods can cause gassiness and bloating. These are some familiar culprits. Beans and lentils contain indigestible sugars called oligosaccharides. These sugars must be broken down by bacteria in the intestines. Fruits and vegetables such as Brussels sprouts, cabbage, cauliflower, carrots, prunes, apricots. These contain sugars and starches that may cause gassiness and bloating. Sweeteners can also cause gas and bloating.
Fructose, a natural sugar added to many processed foods, is difficult for many people to digest.
