A manufacturing factory is accused of emitting high levels of CO2 into the ecosystem. The factory burns coal to heat steel
drums. The factory uses lake water to cool the drums. The water is poured over the drums and then emptied back into the
lake
Scientist A claims the factory is responsible. The burning of coal releases excess CO2 into the atmosphere. This excess CO2 is
transferred to all areas. The CO2 is not lost throughout the system.
Scientist B clams the factory is not responsible. The CO2 is released directly into the atmosphere, not into the lake. The CO2 is
lost into the upper layers of the atmosphere and not cycled back into the ecosystem
The model represents the cycle of carbon in the atmosphere. Which key issue illustrated in the model would best support Scientist
A's claim?
A)
The model shows a factory creating excess levels of CO2
B)
The model depicts a continuous cycle. An increased level in one area will
increase levels throughout.
The model depicts multiple cycles. The atmospheric cycle would show an
increased level of CO2
The model shows high levels of carbon in the lake. Any change to this level
will have a greater impact on the atmosphere.
D)
Answers
The key issue that must be illustrated in the model and best support Scientist A claim is as follows:
The model depicts multiple cycles. The atmospheric cycle would show an increased level of CO2.Thus, the correct option is C.
What is an Ecosystem?An ecosystem may be defined as a place or an area in which individuals of different species live together and interacts with one another for the purpose of food, shelter, and space.
According to Scientist A, the factory is responsible for the excess level of carbon dioxide in the atmosphere. This is absolutely true because the factory burns coal that liberated a high amount of CO2 into the environment.
Apart from this, the factory uses lake water to cool the drums. The water is poured over the drums and then emptied back into the lake. This increases the concentration of CO2 in the lake as well.
Therefore, the correct option for this question is C.

Which domain includes organisms that are called extremophiles (organisms which live in extreme environments)?
Answers
Answer: archaea
Explanation:
Most extremophiles are microorganisms (and a high proportion of these are archaea), but this group also includes eukaryotes such as protists (e.g., algae, fungi and protozoa) and multicellular organisms. Archaea is the main group to thrive in extreme environments.
Archaea domain includes organisms that are called extremophiles (organisms which live in extreme environments).
What are the characteristics of archaea?Archaea is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria.
The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat.
If there is an overgrowth of another organism called Archaea, then the symptom picture can be very different. There can still be bloating, abdominal pain and cramping, but Archaea usually cause constipation, not diarrhea.

How do active and passive transport help a cell respond to changes in the environment?
Answers
- help the membrane maintain homeostasis
Active and passive transport help a cell in responding to the changes in the outside environment as both of these processes help in transporting substance into and out of the cell and maintaining the homeostasis in cell.
What is Cellular transport?
Cellular transport is the process of transportation of substances into and out of the cell. Cellular transport includes different processes such as active and passive transport. The active transport requires energy for transporting substances against the concentration gradient and the passive transport does not require energy as the substances move in the direction from high concentration to low concentration of solutes.
The transport of substances which are required by the cell and excretion is possible through active and passive transport. these processes helps in maintaining homeostasis in the cell.

How does a radio use radiant energy
Answers
Answer Explanation:
A radio uses an electromagnetic energy in the form of radiant energy. This is an invisible energy in the form of radio waves that can travel through space.
When it comes to radio, the radio waves are received by the radio tuner. It is then converted into sound waves that are audible to the human ears. Unlike the other electromagnetic radiation, the radio waves are harmless since they do not cause any harm to the human body. This is the reason why, it is more commonly used for telecommunications and toys controlled by remote.

What would happen if the enzyme used for cellular respiration or photosynthesis to break after a few cycle? Why?
Answers
Answer:
Please mark as brainliest!!!
Explanation:
Cells face a related problem when they break down fuels, such as glucose, to produce ATP. If the cell’s supply of ATP is low, it would do well to break down glucose as quickly as possible, replenishing the ATP it needs to “keep the lights on.” If the supply of ATP is high, on the other hand, it might not be such a good idea to oxidize glucose at top speed. ATP is an unstable molecule, and if it sits around in the cell too long, it’s likely to spontaneously hydrolyze back to ADP. This is like the case of the melted ice cream sandwich: the cell has spent glucose to make ATP, and that ATP ends up going to waste.
It’s important for a cell to carefully match the activity of its fuel breakdown (pathways to its energy needs at a given moment. Here, we'll see how cells turn cellular respiration pathways “up” or “down” in response to ATP levels and other metabolic signals.
