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

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.

What statement about childhood obesity is true?
Obesity can lead to high blood pressure.
Obesity is another word for being overweight.
Obesity is not curable.
Obesity leads to low cholesterol.
Answer:
Obesity can lead to high blood pressure.
Childhood obesity is a severe public health concern that is spreading across the country. Body mass index (BMI) at or above the 95th percentile for kids of the same age and sex is what is referred to as having it. The claims are all accurate.
Obesity can raise the chance of having high blood pressure because it alters the body in ways that enhance that risk. This includes increased blood fat levels, hormonal changes, and an increase in the creation of proteins that can narrow the blood arteries.
Overweight is sometimes referred to as obesity. Body mass index (BMI) at or above the 95th percentile for children is the criterion for this condition.

In 1-2 sentences, explain why mutations can be beneficial to an organism.
Answer:
Some mutations can change genetic variation in a way where an organism can adapt to the surrounding environment. Mutations created gills, which allow fish to breath underwater. Mutations allowed giraffes to reach leaves higher up on trees so they can get food. Mutations also allowed humans to be able to adapt to any environment and situation and continue growing.
Explanation: Brainliest is always appreciated
Mutations are random changes in the DNA sequence of an organism's genome. Mutations can be beneficial to an organism because they can lead to genetic variation, which can allow for natural selection to occur.
What is mutation?Mutation is a process that refers to a change in the genetic material (DNA) of an organism. The genetic material carries the information that determines an organism's characteristics and traits, like eye color, hair color, or susceptibility to certain diseases. Mutations can happen naturally, or they can be induced by various factors such as exposure to radiation, chemicals, or viruses.
Mutations can affect a single base pair of DNA, a larger segment of DNA, or an entire chromosome. They can be classified in many ways, but one of the most common ways is by their effect on the genetic material.

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.
