Why did problems with low oxygen levels and increasing carbon dioxide levels develop in Biosphere?
The problem with low oxygen levels and increasing carbon dioxide levels develop in the Biosphere because the oxygen was absorbed by the population of microbes that are growing in an uncontrolled manner and some other concrete structures present in the Biosphere.
What is Biosphere?A biosphere may be defined as the areas of the surface and atmosphere of the earth or another planet inhabited by living organisms. It may also be regarded as the zone of life on earth.
The amount of carbon dioxide directly depends on the amount of oxygen. If the oxygen level reduces, the level of carbon dioxide will definitely tend to increase.
The level of oxygen accounted as low in the biosphere due to the microbial respiration to a larger extent. And thereby, the level of carbon dioxide increases.

What will most likely happen if a person does not consume the minimum daily requirement of carbohydrates?
If a person does not consume the minimum daily requirement of carbohydrates then the body will use stored glycogen and the person will look unhealthy and become weak after some time.
Importance of carbohydrates: Like other nutrients, carbohydrates are also very essential for various functions of the body. Carbohydrates such as glucose are required for instant energy and day-to-day activities. If there is no or less amount of carbohydrate in the body then our body will start converting the glycogen that is stored in the liver into glucose. After some time, the person will start to appear unhealthy, thin and weak if there is no minimum daily requirement of carbohydrates is met.To know more about carbohydrates, refer:

Transmit Absorb Frequency Light Energy Reflection Transparent
(image attached)
thank you!! WILL GIVE BRAINLIEST!!
Answer:
Transmit - cause (something) to pass on from one place or person to another.
Absorb - take in or soak up (energy or a liquid or other substance) by chemical or physical action.
Frequency - the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
Light Energy - Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes. Light is defined as a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun.
Reflection - the throwing back by a body or surface of light, heat, or sound without absorbing it.
Transparent - (of a material or article) allowing light to pass through so that objects behind can be distinctly seen.
Answer:
In the photo to the left, we can see a red tomato. This tomato appears red because of how it is interacting with the light energy it is receiving. It is reflecting red, and absorbing all other colors: orange, yellow, green, blue, and violet. In this depiction, you can see an entire rainbow of colors going into the apple and only red coming/bouncing (reflecting) back off. You can also see the green of the stem, which is colored in the same way. It absorbs certain frequencies of light--all other colors of light than green--and reflects certain frequencies of light, green light.
In this image, we are able to see the apple and stem because the air/medium that we are seeing this image through is transparent. If the surroundings were opaque, we wouldn’t see red at all (all colors would be blocked if light is blocked).
Another transparent factor in this image are light waves. Actual lightwaves (unless they are being refracted in such a way that they are being spread out--like a laser beam hitting a spray of water mist) are transparent.
You wouldn’t be able to see the [red] lightwaves bouncing off, you would only see the red of the apple. When light is being refracted by a different translucent material--such as glass, plastic, and water--that material is also transmitting the light, it is passing on the light wave. This is when refraction/the bending of light due to a change in media occurs.

Identify the emergent properties of the human respiratory system
The human respiratory system is composed by nose and mouth and continues through the airways and lungs. Air enters the respiratory system through the nose and mouth, passing through the throat (pharynx) and voice box or larynx.
What is the importance of the respiratory system?The respiratory system allows the exchange of gases with atmospheric air, ensuring the concentration of oxygen in the blood, necessary for the body's metabolic reactions, and on the other hand serving as a route for the elimination of residual gases, such as carbon dioxide.
In this case, we can see the multicellular organisms show emergent properties; these are properties that exist due to many different components working together.

Explain how the structure of these specialised cells are adapted for its function.
(I need this to be slightly unprofessional,so please do not copy off a website,I also need this quick)
Answer:
The Roots have what are known as Root Hair Cells on their surface, these Root Hair Cells increase the Surface Area of the Root allowing a more efficient absorption of Water and Mineral Ions. Found within the cells is a large Vacuole. the role of any Vacuole is to hold the nutrients (mainly salts and sugars) needed for the cell to carry out its multiple functions. So, with this Vacuole being large, it allows more of these nutrients to be held for the Root.

In this investigation, you will observe the release of O2 and CO2 into the environment. Gas production by two types of organisms will serve as evidence of photosynthesis and cellular respiration in action. In part 1, you will vary the amount of sugar present and observe the effect on cellular respiration.
Anaerobic (without oxygen) and aerobic (with oxygen) cellular respiration are both possible (without oxygen).
During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilise. As byproducts, carbon dioxide and water are produced.
What are the three stages of cellular respiration?The Krebs cycle, oxidative phosphorylation, and glycolysis—an anaerobic process—are the three phases of aerobic cellular respiration.
All forms of cellular respiration begin with glycolysis, which is anaerobic and oxygen-free. The pathway will go on to the Krebs cycle and oxidative phosphorylation if oxygen is present. However, some species may engage in fermentation to continuously manufacture ATP in the absence of oxygen.
Total amount of ATP molecules generated during aerobic respiration from a single glucose molecule.
During glycolysis:
As 2ATP
From 2NADH 5ATP (oxidation phosphorylation)
In pyruvate oxidation;

What is photosynthesis?
Plants use sunlight, water, and carbon dioxide to produce oxygen and energy in the form of sugar in a process known as photosynthesis.
When performing photosynthesis, plants utilize the ambient carbon dioxide and release the oxygen gas they create into the atmosphere. Gas exchange is the term for this. Stomata, a unique part of the plant's leaf, are used to accomplish this. The guard cells that surround the stomata become turgid or flaccid in response to the entry or escape of water molecules, respectively. Stomata open and gas exchange occurs when the guard cells become turgid, or the other way around.
