1. After reading the passage, how can
you classify steel?
A. Compound
B. Mixture
C. Element
D. Electrons
Answer:
B. Mixture
Explanation:
Steel is an example of a mixture. It's known as an alloy of iron mixed with carbon. The carbon helps to improve its strength and its resistance to fracture. Other percentages of chromium, nickel, vanadium, etc can be added in order to obtain steels of a desired hardness, resistance to corrosion, etc. Due to its high tensile strength, it is used in tools, ships, cars, electrical appliances, weapons, etc.
Please note: I answered this question with my knowledge of steel and to the best of my ability. The passage that was referred to in the excerpt wasn't added for me to use.

What can a scientist
learn by observing the
behaviors of a particular
animal?
Answer: Sense food, Predators
Explanation: They can observe the animals odor and they can also observe the animals predators.
Scientists are inspired to the survey of animal behavior for a variety of reasons, and the ground is pretty varied, ranging from feeding behavior and habitat selection research to mating behavior and social organizations.
What is animal behavior?Animal behavior encompasses all of the ways in which animals interact with other organisms and their physical surroundings.
Behavior can also be defined as a change in an organism's activity in response to a stimulus, an external or internal cue, or a combination of cues.
Animal behavior connects the molecular and physiological aspects of biology to the ecological.
Behavior is the link between organisms and their surroundings, as well as between the nervous system and the ecosystem. One of the most important aspects of animal life is behavior.
Animal research helps scientists understand how living creatures, both human and animal, function.
Animal research allows us to get a close-up look at living organisms and how their physical, chemical, and functional life systems function.
Thus, this way, a scientist can learn many varied things regarding organisms by learning animal behavior.

Which best describes an example of conduction? a heater warming a room water boiling in a pot on a stove an ice cube melting in a cup of hot chocolate cold water moving toward the bottom of a swimming pool
Answer:
boiling in a pot on a stove
Explanation:
Conduction is one of the methods of heat transfer (the other two being convection and radiation). Conduction is the direct transfer of heat through a solid medium. The heat causes the molecules of the objects, which are in direct contact with one another to vibrate, hence, passing the heat.
Based on the above description of conduction, the example that best fits this is BOILING IN A POT ON A STOVE. This is because the pot is in contact with the stove, which is the source of the heat. Hence, heat is transferred from the stove to the pot.

Which one of the following is fixed from the atmosphere by bacteria?
O magnesium
O phosphorus
O nitrogen
O sulfur
O potassium
Nitrogen is the following that is fixed from the atmosphere by bacteria. Thus, the correct option for this question is C.
How nitrogen is being fixed by bacteria?Nitrogen is being fixed with the action of nitrogen-fixing bacteria. These bacteria invade the root of the plants where they stimulate the formation of root nodules.
It is the region where bacteria convert the free form of nitrogen into ammonia. This inorganic form of nitrogen is utilized by plants for their proper growth and development.
The fixation of nitrogen in very important. This is because the atmosphere of the earth consists of 78% of free nitrogen which is not usable in form of living organisms. While the fixation of nitrogen converts this free form of nitrogen into usable forms. For example, it can be easily assimilated by plants and other living organisms.
Therefore, nitrogen is the following that is fixed from the atmosphere by bacteria. Thus, the correct option for this question is C.

B Dissolve the food in water and determine how it changes the boiling point of the water.
C Burn the food and determine how much it raises the temperature of a known amount of water.
D. Dissolve the food in water and determine if it changes the standing temperature of the water.

Explanation:
I am the thing that goes bump in the night. The shadow-like figure all are too afraid to identify in their room. The silent stalker of your waking nightmares and lucid dreams. Do not worry, I can- but will not- hurt you. Your family, however, doesn't have such luck. Do not warn them that I will be following their every move, or it will lead to a grizzly fate for you and your bloodline. I hope that my message has given you closure for the events to come.
In the meantime, you can pray for your family. Maybe I'll have mercy.
The best procedure for a scientist to use in order to determine how many calories are in a certain food is burn the food and determine how much it raises the temperature of a known amount of water. Option C is correct.
When food is burned, it releases thermal energy in the form of heat. The amount of heat energy released can be measured by observing how much it raises the temperature of a known amount of water. This is because water has a specific heat capacity, which means it requires a certain amount of energy to raise its temperature.
By burning the food and using a calorimeter (a device used to measure heat), scientists can accurately measure the amount of thermal energy released. This energy can then be converted to calories, which is a unit of energy commonly used to measure the energy content of food.
