The correct answer to the given question is O Sun > chloroplasts > mitochondria ie. Option (C)
Chemical reactions are how energy moves through living things. One set of substances, known as reactants, are transformed into another set, known as products, during each chemical reaction.Such reactions take place in plants as a result of the sunlight-to-chemical energy conversion process, which powers plant growth and other operations.In particular structures known as chloroplasts, this process, referred to as photosynthesis, involves the combination of carbon dioxide and simple sugars to create more complex carbohydrates. The cells of plants, algae, and some protists include these membrane-bound organelles called chloroplasts.From one atom or molecule to another, electrons move. The relevance of these oxidation-reduction (or redox) reactions in mitochondria to living systems cannot be overstated.In this manner, molecules that carry energy are created and put to use for efficient energy transfer
Hence, the correct answer is O Sun > chloroplasts > mitochondria ie. Option (C)

How does phosphorylation control protein activity?.
Answer:
Phosphorylation offers a dynamic way to regulate protein activity and subcellular localization, which is achieved through its reversibility and fast kinetics. Adding or removing a dianionic phosphate group somewhere on a protein often changes the protein's structural properties, its stability and dynamics.

5. How can we say that added sugar is not necessary for our health (it's not), when we learned that
aerobic cellular respiration uses glucose as a fuel source? (hint - where did hunter/gatherers our
ancestors, get sugar?)
Answer:
more than likely fruits and berries
or natural sugars
The body does not require any added sugar to stay healthy. Hunters/gatherers and our ancestors consumed fruits and milk that are natural sugar to obtain energy.
What is the difference between added sugar and natural sugar?Natural sugars are found in unprocessed food such as fruits and milk.Fruits contain fructose and milk contains lactose.On the other hand, added sugars are the artificial sweeteners that we often add to our daily diet in the form of white sugars and caloric sweeteners. From the perspective of health, it is always better to opt for natural sugar that keeps our body stable energy and stable metabolism.Added sugars are harmful when consumed in higher quantities.Hence, added sugar is not necessary for our health when we have learned that aerobic cellular respiration uses glucose as a fuel source that can be obtained from natural sugar.

Round seeds are dominant over wrinkled seeds in
the pea plants that Mendel studied. Provide the
genotypes and phenotypes of offspring produced
when a heterozygous round plant crosses with
another heterozygous round plant.
Genotype - RR - 25%, Rr - 50%, rr - 25% (1:2:1)
Phenotype - Round seeds - 75%, Wrinkled seeds - 25% (3:1)
How explain your answer?Let the letter "r" stand for the alleles, where R is round seeds and r is wrinkled seeds. A genotype is an individual's genes represented through alleles. Phenotypes are how the genes express themselves. In other words, genotypes will be written using letters, the alleles, and phenotypes will be the possible outcomes of the alleles.
Both of the parent seeds have the genotypes Rr and the phenotype of round seeds.
If you create punnet square (which had four boxes in total) 1 will have RR, 2 will have Rr, and 1 will have rr. These are the ratios for the genotypes. Each box represents 25%, so the percentages will be 25, 50, and 25. Finally, 3 of these boxes (RR and Rr) will result in round seeds because those are dominant. Only the genotype rr will result in wrinkled phenotype. Therefore, the ratio is 3:1 or 75% to 25%.
Thus, this could be the answer.
