A) sources
B) sinks
C) reservoirs
D) all the above
Answer:
the answer is a
Explanation:
Volcanic eruptions, breathing, decaying dead matter, burning fossil fuels, and warm bodies of water are all carbon examples of sources. Therefore, option (A) is correct.
What are sources of carbon?Carbon is one of the most important elements for life on Earth, and it can be found in a variety of sources. Some of the most common sources of carbon include:
Fossil fuels: coal, oil, and natural gas are all made from carbon-based materials that have been buried and transformed over millions of years.Plants: Plants take in carbon dioxide from the atmosphere during photosynthesis and use it to build their tissues.Animals: Animals obtain carbon by eating plants or other animals.The ocean: The ocean contains dissolved carbon dioxide, which can be absorbed by marine organisms and transformed into calcium carbonate, a key component of shells and other structures.Soil: Carbon is stored in soil as organic matter, such as decaying plant and animal material.The atmosphere: Carbon is present in the form of carbon dioxide, methane, and other gases in the atmosphereLearn more about carbon sources, here:

Look at sucrose, a disaccharide, and cellulose, a polysaccharide, on the carbohydrate page. How do you think these two molecules were formed?
help please
Explanation:
Glucose and fructose are joined to form sucrose.
Cellulose is a polymer of glucose.
Monomers of sucrose and cellulose are joined by glycosidic bond to form disaccharides and polysaccharides respectively.
Why is energy transformed from one form to others?
Answer:
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.

how do organisms with many cell types develop from a single cell
Answer:
A multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs.During development, cells use both intrinsic, or inherited, information and extrinsic signals from neighbors to "decide on" their behavior and identity.

Give an example of exaptation in humans.
Answer:
As an example of an exaptation, Gould (1991) used the large size of the human brain and its function of enabling humans to produce speech. The large brain size, according to his argument, originally arose as an adaptation for some (unspecified) functions in humans' ancestral past ( Gould, 1991 ).

In fission, how does the DNA of the daughter cells compare to the DNA of the parent cells?
It is exactly the same
It is different due to meiosis
It it mostly the same with slight changes
It is better than the parent DNA
Answer: It is exactly the same!
In fission, the DNA of the daughter cells compared to the DNA of the parent cells will be exactly the same. The correct option is A.
What do you mean by a parent cell and a daughter cell?The cell that divides to produce two daughter cells is known as the mother or parent cell in the process of cell division. Mitosis produces two offspring cells that are genetically identical to the mother cell. We are all alive now due to a process known as mitosis.
Mitosis is the process through which a single cell divides into two new, identical cells. The initial cell is known as the parent cell, while the newly created cells are known as the daughter cells.
The daughter cell is exactly identical to the mother cell, that's why the DNA will also be the same in both cells.
Therefore, the correct option is A. It is exactly the same.

define thigmotropism, phototropism, and gravitropism and give an example of each
Answer:
a) Thigmotropism
b) Phototropism
c) Gravitropism
Explanation:
A) the turning or bending of a plant or other organism in response to a touch stimulus. example: the folding movement of the Mimosa pudica leaflets, can be considered as an example of thigmonastism.
B) the orientation of a plant or other organism in response to light, either towards the source of light ( positive phototropism ) or away from it ( negative phototropism ).example: Sunflower is a highly phototropic plant. They grow towards the sun and are also seen tracking the movement of the sun throughout the day. That is, the flower keeps changing its direction with the movement of the sun. Sunflower requires more light for its growth and survival.
C) The gravity-directed growth process, called gravitropism, dictates upward shoot growth to ensure a proper positioning of the leaves for efficient photosynthesis and gas exchange. example: tree has fallen over and due to gravitropism exhibits this arched growth.

Answer: Introduced species or exotic species
Explanation:
The introduced species is also called as an exotic species. The exotic species is a species which is not native to a particular location or area but is introduced by humans either accidentally or with the desired species. Such species can be invasive means, it can compete with the native species for resources and can reduce the population of native species.
The given situation is an example of introduction of new species. The weeds are introduced exotic species which could have come along with the desired variety of wheat required for farming in the prairies.

A lake has very deep water at the bottom, in the benthic zone. Why is it more difficult for plants to live in the benthic zone of this lake than in the limnetic zone
Answer:
See the answer below
Explanation:
It is quite difficult for plants to survive in the benthic zone due to the limited penetration of light in the zone when compared to the limnetic zone. The limnetic zone is a well-lit area of a lake or pond while the benthic zone represents an area around the bottom of any water body - marine or freshwater.
Light is an important factor for plants because the light is necessary for photosynthesis - a process through which plants get their foods. Hence, due to limited light in the benthic zone as opposed to the limnetic zone, plants would find it easier to survive in the latter compared to the former.
