Detailed descriptions of what happens to the carbon atom:
during photosynthesis (the light-dependent reactions and the light-independent reactions)
transitioning between photosynthesis and respiration
during cellular respiration or fermentation
An explanation of how the carbon atom is transferred between molecules. Please include descriptions of the molecules involved in each of the processes above and be sure to mention the movement of electrons and energy as the carbon atom moves from one reaction to another.
During cellular respiration:
The cell is oxidized.
Transitioning between photosynthesis and respiration:
It is taken from CO2 converted to glucose then either converted back to CO2 or it is used for other processes and may expelled another way.
How is the carbon atom transferred between molecules:
The electrons move through a series of electron carrier proteins, called the electron transport chains, within the thylakoid membrane.For every 12 of the resulting three-carbon molecules made, two are removed to build organic compounds and 10 continue on in the cycle. The two three-carbon molecules that are removed bond together, forming a six-carbon sugar such as glucose.
What happens to the carbon atom during:
Photosynthesis: carbon is taken in from the air, in the form of carbon dioxide and through the energy provided from sunlight it is converted to a carbon chain known as a sugar.
Explanation:
I did this in 4th grade.
_____ is a product of photosynthesis that becomes

Which statement best describes how a catalyst can speed up a chemical reaction? The catalyst decreases the reaction energy needed. The catalyst increases the concentration of products. The catalyst binds to enzymes to release substrates. The catalyst increases the concentration of reactants.
Answer:
The catalyst decreases the reaction energy needed.
Explanation:
The catalyst speeds up chemical reactions by decreasing the amount of activation energy/reaction energy needed in the reaction.
Compared to reactions without catalysts, they are much faster because there is less activation energy needed.
Catalyst is any substance that causes or increases the rate of a chemical reaction without itself being consumed For example - enzymes are biocatalysts.
The catalyst can speed up a chemical reaction by reducing the activation energy or by changing the reaction mechanism.
The minimum amount of extra energy required by a reacting molecule to get converted into the product is defined as activation energy.
So, the correct answer is The catalyst decreases the reaction energy needed.
Other options-
The catalyst increases the concentration of products- incorrect. Catalysts do not affect the equilibrium concentrations of products or reactants. The catalyst binds to enzymes to release substrates- incorrect. The catalyst binds to the substrate and converts the substrate into products.The catalyst increases the concentration of reactants- incorrect. Catalysts do not affect the equilibrium concentration of products or reactants.Learn more about activation energy-

The fish developed the gills because of____ . Because the fish are now able to swim in deep water, their ____ in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will ____.
1.
A. genetic modification
B. hybridization
C. natural selection
2.
A . competitors
B. predators
c.prey

a .increase
b. decrease
C. not change
Answer:
1 a 2b 3increase
Explanation:
Genetically fishes have gills to inhale they take water through gills and u know water has some amount of oxygen
2 predators increase because many fishes eat each other bcz of competition
3 so relating point 2 competition also increase
The fish developed the gills because of genetic modification . Because the fish are now able to swim in deep water, their predators in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will increase.
What are the adaptations of fish gills?Gills are organs that filter oxygen from the surrounding water. The inside structure of gills is an adaptation that enables two processes to occur: acquiring oxygen and removing a waste product called carbon dioxide.
Fish are able to efficiently exchange gases thanks to the vast surface area of their gills, which allows for this process. The extensive amount of surface area that the blood capillaries in each gill filament contribute because of the little distance that must be traveled for diffusion, both the outer layer of the gill filaments and the walls of the capillaries are only one cell thick.

Please help me, and only provide with the given answers so I am not confused. The curve on the left shows the height of a population of penguins. The curve on the right shows the population five years later. What has happened to this population? (Available answers are in photo) Will mark best answer BRAINLIEST
Explanation:
DIRECTIONAL SELECTION!!!!!!!!!!!!!!!!!!
The population of penguins has gone through the directional selection.
What is directional selection?It is a mode of negative natural selection in which an extreme phenotype is favored over other phenotypes.
This causes the allele frequency to shift over time in the direction of that extreme advantageous phenotype.
How these two graphs shows directional selection?On each graph, the X-axis variable is the type of phenotypic trait (here height) and on the y- axis variable is the number of penguins.
Left graph shows the population before directional selection and right graph shows the population after directional selection.
Here height of the penguins reduces and favored over time due to directional selection.

Which best describes the function of the part labeled b? carries all the genetic information of the organism provides all of the master instructions of the cell joins sister chromatids codes for a specific trait
Answer:
carries all the genetic information of the organism
Explanation:
Genes are located on many chromosomes. In other words, a particular section of the genome is located on each chromosome.
What are the main role of chromosome in the information?The primary function of the chromosomes is to transfer DNA, the fundamental component of genetic material. The genetic instructions for numerous biological functions are encoded in DNA.
Chromosomes, which resemble threads, are located in the nucleus of both animal and plant cells.Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA).
These processes are necessary for the development, maintenance, and procreation of the organisms.Proteins like histones, which protect the chromosomes.
Therefore, DNA is passed down from parents to children and contains the precise instructions that give each sort of living thing its individuality.

The image shows a paramecium and a bacterium. One of these organisms is very good at rapidly adapting to environmental changes because it has the ability to take in stray genetic information from the environment. Which structure allows the organism to do this?
Answer:
The bacteria forms new kind of cells to adapt to a new environment. This adaptation is under tight genetic control, involving the expression of multiple genes.
the bacteria need to adjust their enzyme levels in order to quickly benefit from the nutrient mix that is currently available in the surrounding.
If the living environment undergoes a sudden change, the bacterium's own production of proteins has to fulfill these changes in an effective way.
defend Human Evolution against Scientific Creationism
Answer: According to the National Academy of Sciences (NAS), a scientific theory is “a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.” No amount of validation changes a theory into a law, which is a descriptive generalization about nature. So when scientists talk about the theory of evolution—or the atomic theory or the theory of relativity, for that matter—they are not expressing reservations about its truth.
Explanation: The theory of evolution, meaning the idea of descent with modification, one may also speak of the fact of evolution. The NAS defines a fact as “an observation that has been repeatedly confirmed and for all practical purposes is accepted as ‘true.’” The fossil record and abundant other evidence testify that organisms have evolved through time. Although no one observed those transformations, the indirect evidence is clear, unambiguous and compelling.
