How does carbon not get lost when it moves through the carbon cycle
Answer:
Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy. Carbon moves from one storage reservoir to another through a variety of mechanisms. For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules. Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle. The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. Two-way carbon exchange can occur quickly between the ocean’s surface waters and the atmosphere, but carbon may be stored for centuries at the deepest ocean depths. Rocks like limestone and fossil fuels like coal and oil are storage reservoirs that contain carbon from plants and animals that lived millions of years ago. When these organisms died, slow geologic processes trapped their carbon and transformed it into these natural resources. Processes such as erosion release this carbon back into the atmosphere very slowly, while volcanic activity can release it very quickly. Burning fossil fuels in cars or power plants is another way this carbon can be released into the atmospheric reservoir quickly.Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. As a result, the amount of carbon dioxide in the atmosphere is rapidly rising; it is already considerably greater than at any time in the last 800,000 years. The ocean absorbs much of the carbon dioxide that is released from burning fossil fuels. This extra carbon dioxide is lowering the ocean’s pH, through a process called ocean acidification. Ocean acidification interferes with the ability of marine organisms (including corals, Dungeness crabs, and snails) to build their shells and skeletons.

a network of passageways in which chemical compounds
are manufactured, processed, and transported is ______?
Answer:
Endoplasmic reticulum
Explanation:
The endoplasmic reticulum is a network of passageways found in the cytoplasms of eukaryotes for the purpose of manufacturing, processing, transporting, modifying, and folding proteins. There are two types of endoplasmic reticulum and they are the smooth and rough endoplasmic reticulums.
Unlike the smooth endoplasmic reticulum, the rough endoplasmic reticulum has ribosomes attached to it.

Which of the following is an example of adhesion in organisms?
a. capillary action of liquid in plant stems
b. release of sweat to reduce body heat
c. movement of ions to maintain homeostasis
d. pumping of blood through the circulatory system
Answer:
a. capillary action of liquid in plant stems
Explanation:
Vascular plants need to transport water from roots to stem and leaves. For this purpose, water molecules adhere to xylem cell walls (xylem is one of the two classes of transport tissues in higher plants). Adhesion, also known as capillary action, is a mechanism produced when water molecules cling to xylem cell walls. Thus, adhesion can be defined as a molecular mechanism caused by the attraction between molecules, in this case, between molecules of the xylem and water molecules.
If a certain organism is a primary consumer, what best explains its position in the food web? (See picture above)
A. X, because organism X has the same role as the grasshopper
B. y, because organism Y has the same role as grasshopper
C. x, because organism X has the same role as the baby sparrow
D. Y, because organism Y has the same role as the baby sparrow
Answer:
A. X, because organism X has the same role as the grasshopper
Explanation:
In the food web the organism is denoted by X and it shares the same role as the grasshopper.
A primary consumer is mostly a herbivore. They feed directly on plant matter and convert them into useful nutrition for their own needs.
Grasshoppers feed on grasses. They are able to process plant matter into digestible food materials.Organisms of this kind are primary consumers. Organism such as Y are the secondary consumers. They feed on other organism but not directly on the plants.Answer:
A : X, because organism X has the same role as the grasshopper

What did you include in your response? Check all that apply. Distance and displacement are the same in the 100-m sprint. Velocity and speed are the same in the 100-m sprint. Distance is 400 meters in the 400-m sprint. Displacement is zero in the 400-m sprint. Velocity is zero in the 400-m spri
Answer:
Distance and displacement are the same in the 100-m sprint, therefore, velocity and speed are the same in the 100-m sprint.
Distance is 400 meters in the 400-m sprint, therefore Speed is not zero in the 400 M sprint.
Displacement is zero in the 400-m sprint, therefore, Velocity is zero in the 400-m sprint
Note: The question is missing some details which is given below;
A 100-meter sprint is a race using only the straight side of a racetrack. a 400-meter sprint is a race that makes one complete lap around a racetrack. why are velocity and speed the same for a 100-m sprint but not a 400-m sprint?
Explanation:
The speed of a body is the ratio of the distance covered and the time taken whereas the velocity of a body is the rate of change of displacement with time.
Distance measures the total length of space covered throughout the duration of motion, whereas displacement measures the change in a specified direction from a specific point.
In the 100 m race along a straight line, both distance and displacement = 100 m, therefore speed and velocity are the same. However, in the 400 m race, distance covered is 400 m, but the displacement is zero since the person returns to his/her starting point. Therefore, speed is not equal to zero, but velocity is equal to zero.
What evidence do we have of Neanderthal intelligence?
Answer:
What's more, genetic evidence has shown that modern humans mated with Neanderthals before these individuals disappeared about 40,000 years ago. Many of us today still have 1 to 2 percent Neanderthal DNA, findings that suggest that modern humans who encountered these individuals saw them as people, too.
What two things can cause a DNA helix to separate into two strands

A day on saturn takes about 10 earths hours. Which fact would best explain this short day?
Answer:
Saturn rotates faster than Earth!
Explanation:
A day is one rotation of a planet, so a planet that rotates faster has "shorter" days.
Hope this helps!
The rotation and revolution of the planets around the Sun determine the length of day and night on the planets. The Earth takes 24 hours to rotate, Mars takes 24.6 hours, while Saturn takes 10 hours.
The fact that described the short day of Saturn is that Saturn rotates faster than the Earth.
It can be explained as:
Earth is the only habitable planet in the solar system, which rotates on its axis in approximately 24 hours. Earth takes 365 days to revolve around the Sun. Mass and density of the planet determine the rotation of the planets. Saturn is a gaseous planet, which is also an outer planet. The day length on Saturn is 10 hours long, which is shorter than the Earth hours.
Thus, Saturn rotates faster than Earth and has a shorter day length.
