Carbon dioxide and water are reactants in cellular respiration and products of photosynthesis.
Carbon dioxide is a reactant of cellular respiration, and water is a product of photosynthesis.
Carbon dioxide is a product of photosynthesis, and water is a reactant in cellular respiration.
Answers
Answer:
the answer is C
Explanation:
The type of the respiration that are taking place inside the cells are called as the cellular respiration in which carbon dioxide is the reactant and the water along with it is the bi product. The correct answer is option C.
What are the two products in the process of photosynthesis ?
The products of photosynthesis are oxygen that is released out with the glucose that is the sugar molecule which is the stored form of energy.
Photosynthesis converts out carbon dioxide and the water into the oxygen and typically glucose. Glucose is then used as the food by plant and the oxygen that is a by-product of the process. Cellular respiration later just converts out oxygen with the glucose into the water and carbon dioxide.
Water and the carbon dioxide are just the by- products along with the ATP that is the energy which is just transformed out from process. In the process of the cellular respiration where the glucose and oxygen together just reacts in order to form the ATP. Water and the carbon dioxide are just released as the byproducts.

The endosymbiotic theory states that eukaryotes evolved from prokaryotes. Which statement is part of the endosymbiotic
Answers
Note about the question:
Statements are missing, and I failed to find the complete question. So here I give you some details about the theory that will help you to indetify the correct statement.
Answer and Explanation:
The endosymbiotic theory essentially states that some organelles of the eukaryotic cells, such as mitochondria and chloroplasts, were once free-living bacteria. Probably, these organisms must have been phagocytosed but not digested by another cell. On the contrary, these bacteria were able to adapt to their host in such a way that the two cells established a dependent relationship with each other.
It is speculated that chloroplasts derivate from cyanobacteria and that mitochondria derivate from rickettsias.
Cells would be beneficiated from this new bond, at the point that they could not survive by themselves anymore.
This theory is supported by a few characteristics of the chloroplasts and mitochondria that suggest that they once were a free cell. For example,
Both organelles present their genetic material. This DNI is independent of the cell´s DNA, is bi-catenary and circular, identical to the bacterial DNA, and very different from the one of the eukaryotic cells. These organelles do not divide by mitosis. Instead, they do it by binary fission and are capable of synthesizing their ribosomes and organelles. Both organelles present a double membrane, a characteristic that reinforces the idea of being phagocyted. The internal membrane looks identical to the bacteria membrane, while the external membrane looks like the eukaryotic one. In fact, in this internal membrane are placed the energy centers, exactly as it occurs in bacterias membrane. Finally, the sizes of the organelles are similar to the size of some procaryotes.PLLLZ HELP!!! WILL MARK BRAINLIST! IM HORRIBLE AT SCIENCE!

Explain how endospores have allowed some bacteria, like tetanus, to be a successful species.
Answers
Answer:
Endospores allow Clostridium tetani (causative agent of tetanus) to survive harsh conditions in the environment. Because tetanus is an obligate anaerobe, oxygen is a harmful environmental factor. Endospores also allow the bacteria to resist desiccation (drying) and high temperatures.
The bacteria can be dormant as endospores until they are in favorable conditions. At this point, they will germinate into vegetative cells where they will be able to reproduce until conditions become unfavorable and they form endospores again.

discuss the stages of the cell cycle mechanism that regulate it and how this cycle is related to the growth and maintenance of organisms
Answers
Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
Cyclins regulate the cell cycle only when they are tightly bound to Cdks. To be fully active, the Cdk/cyclin complex must also be phosphorylated in specific locations. Like all kinases, Cdks are enzymes (kinases) that phosphorylate other proteins. Phosphorylation activates the protein by changing its shape.

What adaptations are common for animals in hot and cold climates? Name at least two for both hot and cold climates.
Answers
Answer:
Explanation:
1. hot- camels live in hot deserts where its extremely hot and sandy therefore they have long eyelashes to protect their eyes just in case of sand storms
2. cold- penguins live in very cold climates so they have both black and white fur white so they can disguise in the snow from predators and black so they can absorb heat from the sun when they get extremely cold
3. hot -thick fur on the top of the body for shade, and thin fur elsewhere to allow easy heat loss. a large surface area to volume ratio - to maximise heat loss. the ability to go for a long time without water - they lose very little water through urination and perspiration. the ability to tolerate body temperatures up to 42°C

Answers
Answer:
Electron transport chain
This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP.The citric acid cycle is a series of chemical reactions that removes high-energy electrons and uses them in the electron transport chain to generate ATP. One molecule of ATP (or an equivalent) is produced per each turn of the cycle.

Answers
Answer:
Meiosis consists of one round of DNA replication and two rounds of chromosome segregation.
Explanation:
DNA replicates twice during meiosis. Meiosis consists of one round of DNA replication and two rounds of chromosome segregation. Therefore, this statement in false.
What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome.
Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm). In humans, body (or somatic) cells are diploid.
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

Answers
Answer:
Cell membranes had formed
Explanation:
I hope it helped
The Miller and Urey experiment showed for the first time that the organic molecules necessary for life could be formed from inorganic components.
In 1953, scientists Stanley Miller and Harold Urey experimented to verify that organic molecules could form spontaneously under environmental conditions similar to those of the Earth in its early days.
To do this, they built a closed system in which they included a container with hot water and a mixture of gases that supposedly abounded in the Earth's atmosphere at the beginning. In addition, they devised the way to simulate lightning bolts that provided energy for chemical reactions in the atmosphere.
After running their experiment for a week, they resulted in the formation of various types of amino acids, sugars, lipids, and other organic molecules. This experiment allowed them to show that at least some of the structural units of these molecules could form spontaneously from simple compounds.
