1.
Observation:hypothesis::hypothesis:_________?
Correct Answer
B. Investigation
Explanation
The analogy between "observation" and "hypothesis" suggests that they are related in a cause-and-effect manner. An observation is a factual statement or evidence that leads to the formation of a hypothesis, which is a proposed explanation or prediction based on the observation. Similarly, a hypothesis leads to an "investigation," which involves gathering more data, conducting experiments, and analyzing the results to test the validity of the hypothesis. Therefore, "investigation" is the appropriate term that completes the analogy.
2.
Name two types of microscopes.
Correct Answer
light and electron
Explanation
Light and electron microscopes are two types of microscopes commonly used in scientific research and analysis. Light microscopes use visible light to illuminate the specimen and produce an image, allowing for the observation of cells, tissues, and small organisms. On the other hand, electron microscopes use a beam of electrons to create a highly detailed image with a much higher magnification and resolution compared to light microscopes. This enables researchers to study the ultrastructure of cells, molecules, and even individual atoms.
3.
Which of the following measurements is most precise?
Correct Answer
D. 2.6379 cm
Explanation
The measurement 2.6379 cm is the most precise because it has the greatest number of decimal places. The other measurements have either no decimal places or fewer decimal places, indicating less precision.
4.
Name one propert of life.
Correct Answer
cell orginization, homeostasis, metabolism, responsiveness, reproduction, heredity, growth
Explanation
The correct answer is that one property of life is cell organization, homeostasis, metabolism, responsiveness, reproduction, heredity, and growth. These properties are commonly associated with living organisms. Cell organization refers to the structural arrangement of cells, which are the basic units of life. Homeostasis is the ability to maintain a stable internal environment. Metabolism involves the chemical processes that occur within an organism to maintain life. Responsiveness is the ability to react to stimuli. Reproduction is the process of producing offspring. Heredity involves the passing of traits from parents to offspring. Growth refers to an increase in size or number of cells in an organism.
5.
Photosynthetic algae are _________?
Correct Answer
A. Producers
Explanation
Photosynthetic algae are classified as producers because they have the ability to convert sunlight into energy through the process of photosynthesis. They use this energy to produce their own food in the form of carbohydrates, which makes them self-sufficient and independent from consuming other organisms. As producers, they play a crucial role in the food chain by providing a source of energy and nutrients for other organisms in the ecosystem.
6.
Physical location: habitat::function:_______?
Correct Answer
C. Niche
Explanation
The given analogy is comparing physical location to habitat, suggesting that habitat is a characteristic or quality of physical location. Similarly, the analogy is asking for a characteristic or quality of function. Among the options provided, "niche" is the most appropriate choice as it refers to the specific role or function that an organism has within its habitat.
7.
List the three types of symbiotic relationships.
Correct Answer
paraticism, mutualism, commesalism
Explanation
The three types of symbiotic relationships are parasitism, mutualism, and commensalism. Parasitism is a relationship where one organism benefits at the expense of another organism. Mutualism is a relationship where both organisms benefit from each other. Commensalism is a relationship where one organism benefits while the other is neither harmed nor benefited.
8.
Kleptoparaticism is _________________________?
Correct Answer
B. The stealing of food
Explanation
Kleptoparaticism refers to the act of one organism stealing food from another. It is a form of interspecific interaction where the thief benefits by obtaining food without expending energy in hunting or foraging, while the victim loses its food resources. This behavior is commonly observed in various animal species, such as birds stealing prey from each other or kleptoparasitic insects stealing food from other insects. Kleptoparaticism is an adaptive strategy that allows certain organisms to exploit the resources of others for their own survival and reproduction.
9.
List the three subatomic particles.
Correct Answer
proton, neutron, and electron
Explanation
The three subatomic particles are the proton, neutron, and electron. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Protons and neutrons are found in the nucleus of an atom, while electrons orbit around the nucleus. These particles are the building blocks of atoms and determine the properties and behavior of different elements.
10.
Acidic solutions have a pH that is _____________?
Correct Answer
D. Less than 7
Explanation
Acidic solutions have a pH that is less than 7. This is because pH is a measure of the concentration of hydrogen ions in a solution. In acidic solutions, the concentration of hydrogen ions is higher than the concentration of hydroxide ions. The pH scale ranges from 0 to 14, with 7 being neutral. Any solution with a pH less than 7 is considered acidic.
11.
A molecule that is partial positive on one side and partial negative on the other is called a ________?
Correct Answer
C. Polar molecule
Explanation
A molecule that is partial positive on one side and partial negative on the other is called a polar molecule. This is because the molecule has an uneven distribution of electron density, resulting in a positive charge on one side and a negative charge on the other. This polarity allows polar molecules to interact with other polar molecules or ions through attractions known as dipole-dipole interactions. This property is important in various biological and chemical processes, such as solubility, membrane transport, and protein structure.
12.
Name two properties of H2O.
Correct Answer
adhesion, cohesion, high heat capacity, solvent
Explanation
H2O, also known as water, exhibits the properties of adhesion and cohesion. Adhesion refers to the ability of water molecules to stick to other substances, while cohesion refers to the attraction between water molecules themselves. Additionally, water has a high heat capacity, meaning it can absorb and retain a significant amount of heat without a large increase in temperature. Lastly, water is a solvent, meaning it has the ability to dissolve a wide variety of substances.
13.
Sucrose, lactose, and peptidose are _______________?
Correct Answer
enymes, proteins
Explanation
Sucrose, lactose, and peptidose are not enzymes, but they are types of sugars. Sucrose is a disaccharide composed of glucose and fructose, lactose is a disaccharide composed of glucose and galactose, and peptidose is a term used to describe a peptide or protein fragment. Therefore, the correct answer is incorrect.
14.
List the three types of asexual reproduction.
Correct Answer
fission, budding,regeneration
Explanation
The correct answer is fission, budding, and regeneration. Asexual reproduction is a type of reproduction that involves only one parent and produces offspring that are genetically identical to the parent. Fission is the process where an organism splits into two or more parts, each of which grows into a new individual. Budding is when a new organism grows out of the body of the parent organism. Regeneration is the ability of an organism to regrow lost or damaged body parts. These three types of asexual reproduction allow organisms to reproduce without the need for a mate.
