Gravitational Potential Energy
Explanation:
The general expression for gravitational potential energy arises from the law of gravity and is equal to the work done against gravity to bring a mass to a given point in space.
When wood combines with oxygen and burns, ashes and carbon dioxide are produced. How does the Law of Conservation of Matter relate to this observation?
A. The mass of the wood will be destroyed.
B. The weight of these substances will change but the mass will stay the same.
C. The mass of each of these substances will be the same before and after the reaction.
D. The mass of the wood and the oxygen burned will equal the mass of the ashes and the carbon dioxide produced during the reaction.
Answer:
Option C
Explanation:
Conservation of matter states that matter can not be created nor it can be destroyed. It can only be changed from one form to the other.
In this case, the matter contained is wood (solid) is converted into ash (solid) and carbon dioxide (gas).
The amount of all substances remains constant irrespective of any condition during a chemical reaction
Hence, option C is correct
In an article about saving the whales written by a marine biologist, which word might be used by the author to make you want to help with saving the whales?
Answer:
Endangered
Explanation:
Endangered species are organisms that are at risk of extinction if deliberate efforts are not made to conserve them due to a rapid decrease in their population.
Hence, if a marine biologist writes an article about saving whales and labels them as endangered species, all efforts should be geared towards saving the animals lest they go extinct and leave a vacuum in the functioning of the ecosystem. Every species have the critical roles they play in the functioning of the ecosystem and the extinction of any particular species represents a loss that might not be replaceable.

1. Explain how the energy flows within living systems. Include the
following concepts:
• 10% Energy Transfer
• Food Web
• Food chain
(3 points)
2. Explain how energy is transformed through the process of
photosynthesis. (2 points)
Answer:
Explanation:
energy flows from the Sun to producers and then to consumers. The path is linear as the energy present in one step is transferred to the next. You can find specific examples of this pathway in an ecosystem. Energy may be lost in living systems as it flows through them.
Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
10% energy transfer is the law of energy transfer in which about 10% of the energy is transferred to the next trophic level in an ecosystem.
What is the energy flow in an ecosystem?Energy flow is the flow of energy which occurs through the living things within an ecosystem. All the living organisms in an ecosystem can be organized into different groups such as producers and consumers, and the producers and consumers can be further organized into a proper food chain. Each level within a food chain is called as trophic level.
1. 10% energy transfer is the law which states that 10% of the total energy is transferred to the next trophic level and 90% is lost into the atmosphere.
Food web is a network of interlinked food chains. In this different organisms are produce at each trophic level which provides the organism with different options for their food.
Food chain is a linear network of different organisms at different trophic levels in an ecosystem.
2. Photosynthesis is the process of energy transformation in which light energy in the form of sunlight is transformed into chemical energy in the form of chemical bonds present in the carbohydrate molecules.

Start a discussion on Homeostasis. List facts and opinions, then compare and contrast.
Answer:
- Homeostasis is the ability of living systems to maintain a steady and uniform internal environment to allow the normal functioning of the systems.
- It is the tendency to achieve equilibrium against various natural and environmental factors.
- Homeostasis results in a dynamic equilibrium, where continuous changes keep on taking place, and yet steady conditions are maintained.
- Homeostasis is mainly involved in managing various internal variables of the living system like body temperature, pH of various fluids, the concentration of different ions, and the body sugar level.
- A number of regulatory mechanisms are employed to resist changes in the body against environmental and bodily factors.
- Homeostasis can be maintained by separate organs or by the entire body at once.
Maintaining homeostasis/Homeostasis Mechanisms
Homeostasis is maintained by a complex system that consists of individual units working in a particular sequence to balance a given variable. All homeostasis mechanisms consist of four separate units, which are:
1. Stimulus
The stimulus is something that results in changes within the system involving the variable.
The stimulus represents that the variable has moved away from its normal range, initiating the process of homeostasis.
One example of this is the increased temperature of the body above 37°C due to various causes. The increased temperature indicates that the temperature of the body has gone higher than its higher range.
2. Sensor/ Receptor
The sensor or receptor is the sensing unit of homeostasis, where it monitors and responds to the changes in the body.
The changes in the system are realized by the sensor, which then sends the information to the control unit.
The nerve cells and receptors like thermoreceptors and mechanoreceptors are examples of sensor/ receptors.
3. Control unit
Once the information is sent to the control unit, it tallies the changed value to its normal value.
If the value is different from the normal value, the control center activates the effectors against the stimulus.
The thermoregulatory unit in the hypothalamus of the brain that controls the temperature of the body is an example of the control unit.
4. Effector
Effectors can be muscles, organs, glands, or other similar structures that are activated as a result of the signal from the control unit.
An effector is a target which is acted upon by the control unit to bring the value of variable back to normal.
The effector essentially counteracts the stimulus to nullify its effect.
In the case of thermoregulation, the sweat glands are effectors that are acted upon by the thermoregulatory unit to produce sweat so as to bring the value of body temperature back to its normal value.

In 2-3 sentences explain pollination.
Answer:
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. (I'm sorry this is about Pollution, it should be about Pollination, I misread it sorry,)
Pollination:
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.
Imagine that you are hiking and discover an outcrop of sedimentary rock. The rock is arranged in three distinct layers that appear to be undisturbed. When you examine the layers more closely, you observe fossils in the bottom and middle layers. What inferences can you make about these fossils based upon your observations and your knowledge of the law of superposition?
Answer:
The age of fossils are in millions.
Explanation:
These fossils were present on the earth millions of years ago due to different and unique structure of the fossil. The fossil is present in the bottom of the middle layer indicates that the more age of fossil i.e. millions of years according to the law of superposition. This law states that in an undisturbed layers of rocks, the top layer is the younger layer than middle and bottom layers which is older than the top layer, so we can say that fossils from deeper layers are older than fossils from the top layers of rocks.

Which best describes what Shah is doing? replication repetition both repetition and replication neither repetition nor replication
Answer:
This question is incomplete. The complete part of the question is as follows:
Shah did not trust the results of an experiment that she had read about, so she is conducting the experiment herself. She goes through the same set of steps and measures the effect of the amount of sugar on a single organism.
Which best describes what Shah is doing?
The answer is A. Replication
Explanation:
In an experiment, replication is the process of repeating an experiment that was formerly conducted by another experimenter in order to ensure accuracy. Note that, an experiment is 'replicated' under the same conditions as it was conducted previously.
This is the case in this question involving Shah who conducted an experiment herself because she didn't trust the results of the experiment she read about. She conducted an experiment that has already been conducted by another experiment, hence, it is a REPLICATION.
