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.

How does sea level change when Earth's global temperature is lower?
A. Glaciers grow bigger, causing sea level to fall.
B. Glaciers grow smaller, causing sea level to fall.
C. Glaciers grow smaller, causing sea level to rise.
D. Glaciers grow bigger, causing sea level to rise.
Glaciers grow smaller, causing sea level to rise when Earth's global temperature is lower. Thus, the correct option is C.
Sea level lowers during cold climate periods, known as glacial epochs or ice ages, due to a shift in the global hydrologic cycle, in which water evaporates from the oceans and is stored on the continents as massive ice sheets, extended ice caps, ice fields, and mountain glaciers. At the last glacial maximum, some 20,000 years ago, global sea level was about 125 meters lower than it is today.
What is interglacial epochs?Because the melting North American, Eurasian, South American, Greenland, and Antarctic ice sheets returned their stored water to the world's oceans as the climate warmed, sea level rose. Sea level is at its highest during the warmest eras, known as interglacial epochs.
We are currently living in the most recent interglacial, which began around 10,000 years ago and is referred to by geologists as the Holocene Epoch. Sea levels were about 3 to 20 meters higher than they are now during several previous interglacials.

Which best describes the Big Bang Theory?
A. Stars burn off their fuel, expand, and shed their shells.
B. Matter was compressed into a single point and then exploded
outward to form the universe.
C. A black hole exploded, creating stars.
Answer:
B
Explanation:
before the big bang there was a lot of nothing packed into nothing.matter and time. space and stars did not exist till then scientists haven't found a way yet to know what was there before the big bang, so we cannot say stars exploded or a black hole died. but what we can say is that very dense pinprick very very very very very dense pinprick of nothing-ness expanded and created matter as it heated up
Answer:
B
Explanation:
Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.

c. Provide at least 2 pieces of evidence that support the order you determined for the 3 skeletons.
According to the images, it can be concluded that the organization of the skeletons from the oldest to the most recent is C, A and B, because they show human evolution.
How are skeletons organized and why?The skeletons are organized chronologically from the oldest to the most recent as follows: C, A and B. This organization is due to the fact that some particular characteristics are evident in each of them, such as:
In skeleton C, it is the oldest because it has a tail and its position is quadrupedal, it can be related to the primates from which the human emerged.Skeleton A is the intermediate point between the primate and the human, it maintains a quadrupedal position but more upright and no longer has a tail.Skeleton B is the most recent example of a skeleton because it already walks completely upright and its morphology is the most similar to that of a contemporary human.Learn more about skeletons in: https://brainly.com/question/14446520

When minute samples of DNA need to be genetically analyzed for identification purposes, which test can be effectively used to make more of the DNA
Answer:
When minute samples of DNA need to be genetically analyzed for identification purposes, which test can be effectively used? Fluorescent dye can be used as a label to trace antibody-antigen reactions in an ELISA assay
DNA is the genetic material that is the unit of inheritance. Small DNA samples can be increased in amount by the technique called PCR. Thus, option D is correct.
What is PCR?Polymerase chain reaction (PCR) is the technique used in biotechnology to quantitatively increase the amount of genetic material. It has been known to create billions and millions of copies of the sample.
The small DNA sample can be amplified by the process of PCR which involves the production of the DNA sample by the polymerase and primers to add the bases to the strand.
The DNA undergoes thermal cycling where the temperature of the system first increases in denaturation followed by a drop in temperature in annealing and lastly again a rise of temperature in extension.
Therefore, the PCR technique can increase the amount of small DNA samples.
