A scientist is studying an aquarium ecosystem that contains water, plants, and fish that eat those plants. The aquarium has glass walls so light can get in, but it is sealed so no material can move into or out of the tank. When the scientist turned the aquarium's light on, carbon dioxide in the water started decreasing. How is carbon moving and what is happening to the amount of carbon in the living things inside the aquarium? Explain your thinking as completely as possible.
PLEASE PLEASE PLEASE CAN SOMEONE HELP ME WITH THIS QUESTION!!!

Carbon moving and what is happening to the amount of carbon in the living things inside the aquarium is by photosynthesis.
What is aquarium?
An aquarium (plural aquariums or aquaria) is a vivarium, usually contained in a clear-sided container (typically constructed of glass or high-strength plastic) in which water-dwelling plants and animals (usually fish).
According to this question, the aquarium contains water, plants and fish. The glass of the aquarium is transparent and allows the passage of light. Plants are unique set of organisms that have the ability to produce their own food (organic molecule) using the energy from light which they absorb via the Chlorophyll pigment in their Chloroplast. This process carried out by plants is called PHOTOSYNTHESIS.
The amount of carbon in form of carbondioxide (CO2) decreases when the light was switched on in the aquarium due to the process of photosynthesis carried out by the plants.

changes in ecosystems can be attributed to natural causes, such as natural disasters, seasonal variations in climate, currents, and tidal activity. many of these changes can affect the amount of food
resources available in an ecosystem. research one natural change that currently affects or could affect
the aquatic ecosystem you chose. use your food web model to explain how this change can affect the
competition of food resources in your aquatic ecosystem.
the ecosystem that i made my food web model after was the san francisco bay!!
A natural change that currently affects or may affect the aquatic ecosystem of the bay of san francisco is the warming of the waters due to global warming and rising river levels.
What happens to water in global warming?As a result of global warming and the increase in the emission of greenhouse gases, the heat retained in the atmosphere ends up being stored in the oceans, affecting the temperature and circulation of water, in addition to accelerating the process of melting of the polar ice caps.
With this information, we can conclude that a natural change that currently affects or may affect the aquatic ecosystem of the bay of san francisco is the warming of the waters due to global warming and rising river levels.

Answer:
B
Explanation:
The advantage of cyanobacteria over alternate biofuels is that multiple processing steps can be avoided.
Cyanodiesel, a byproduct of cyanobacteria, has unlimited growth potential and are used in various fields of biotechnology.
Benefits of Cyanobacteria-derived fuels ?⇒ Transform solar energy into chemical energy by the process of photosynthesis
⇒ Fixing of atmospheric nitrogen, helping in the increase of soil fertility
⇒ Widespread applications in pharmaceuticals and agriculture
The advantage of cyanobacteria to produce isobutanol over alternate biofuels is that multiple processing steps required in biofuel production from other sources can be avoided. So option B is correct.
How are cyanobacteria useful in producing isobutanol?Cyanobacteria are recently been engineered to produce a variety of chemicals, such as ethanol, Isobutanol, and Isoprene, directly from solar energy, carbon dioxide, and water. This makes cyanobacterium a potential new cell factory for the production of energy and chemicals to meet global energy and climate change challenges.
Synthetic cyanobacteria are engineered through heterologous biosynthesis to create value-added chemicals through photosynthesis. Several chemicals have been successfully generated in synthetic cyanobacteria.

Answer:
A trench would be formed, a ridge would develop, magma would be released and the crust would separate.
Explanation:
Look at the picture and try to identify the process. Once you have identified the process, think of the landforms formed and what processes are involved. The phrase "seafloor spreading" in the question tells us that this is an oceanic divergence process.
When two oceanic plates diverge (move apart), tensional forces are exerted. Fractures may occur (faulting) near the plate boundary. Magma rises at the zone of divergence (a large fracture between the two plates). It solidifies and builds up to form a mid-oceanic ridge, a central ridge dividing the ocean basin. The cooled magma forms a new sea floor between the diverging plates (sea floor spreading).
For your info, I only gave you the explanations for the options chosen and there are actually more landforms and processes that occur in oceanic divergence. If you want the full explanation of the entire process, let me know.
What is the genotype of the dad?
What is the genotype of the mom?
What is the genotype ratio among their children?
What is the phenotype ratio among their children?
Answer:
The genotype of the Dad must be X^AY because that's the only possible genotype for a normal male.
The genotype of the mom must be X^AX^a because that's the only way to have a colorblind son while being a normal mom. The colorblind son gets a Y from his dad and X^a from his mom.
The genotype ratio among the children must be 25% heterozygous dominant, 50% homozygous dominant, and 25% heterozygous recessive.
The phenotype ratio among the children must be 75% normal and 25% colorblind.
