The main calvin cycle byproduct that is exported from the chloroplast and used by the plant cell is trise phosphate.
What is Calvin cycle ?Calvin cycle, also known as the C3 cycle, is a series of chemical processes used by plants to convert carbon dioxide and other chemicals into glucose.
Three molecules of carbon dioxide are used in a full cycle, which results in the production of one molecule of the three-carbon chemical glyceraldehyde-3-phosphate (Gal3P). Normally, the chloroplasts either export this three-carbon sugar phosphate or transform it internally into starch.Since the first stable compound in Calvin cycle is a 3 carbon compound (3 phosphoglyceric acid), the cycle is also called as C3 cycle. The reactions of Calvin's cycle occur in three phases.Learn more about Calvin cycle here:

there are two types of cells, prokaryotic and eukaryotic. although the types of cell share some similarities, compartmentalization is not a shared characteristic. it has been theorized that chloroplast evolved from prokaryotic cells living symbiotically within a larger cell. describe the endosymbiotic theory. explain how chloroplasts are similar to prokaryotic cells. provide observations and evidence that supports the theory.
Answer:
Chloroplasts and mitochondria are said to be prokaryotic as they have their own genes on a small, circular chromosome but no nucleus. This chromosome has little non-coding DNA, similar to those of bacteria. Chloroplasts and mitochondria also make some of their own proteins from their gene.
hence endosymbiotic theory states that some eukaryotic cell organelles like mitochondria and chloroplast evolved from free living prokaryotes.the prokaryotes or single celled organism fuse to form eukaryotes as stated by Margulis.
Explanation:
According to the endosymbiotic theory, some eukaryotic cell organelles, such mitochondria and plastids, descended from prokaryotes that were free to move around.
What are the characteristics of endosymbiotic theory?The endosymbiotic hypothesis postulates that some organelles of eukaryotic cells were once prokaryotic bacteria.
Chloroplasts and mitochondria are identical in size to prokaryotic cells and divide by binary fission. The DNA in mitochondria and chloroplasts is circular rather than linear.
The information available supports Margulis' hypothesis that the mitochondrial endosymbiosis marked the beginning of the evolution of the eukaryotic cell.

Answer:
Alzheimer's disease
Explanation: did this in my biology class as well hope it helps though
A group of experimental drugs focuses on blocking the construction of neurofibrillary tangles by keeping tau protein anchored to microtubules as a possible treatment for Alzheimer's disease.
Neurofibrillary tangles are abnormal aggregations of tau protein that accumulate inside neurons in the brains of individuals with Alzheimer's disease. These tangles disrupt the normal functioning of neurons and contribute to the progression of the disease. Therefore, developing drugs that target the formation of neurofibrillary tangles is a potential therapeutic approach for Alzheimer's disease.
The experimental drugs mentioned in the statement aim to block the construction of neurofibrillary tangles by keeping tau protein anchored to microtubules. Tau protein normally plays a critical role in stabilizing microtubules, which are essential components of the cell's cytoskeleton responsible for maintaining cell shape and facilitating intracellular transport.
In Alzheimer's disease, abnormal modifications of tau protein cause it to detach from microtubules, leading to the formation of neurofibrillary tangles. These experimental drugs are designed to prevent the detachment of tau protein from microtubules, keeping it anchored and inhibiting the formation of tangles.
By maintaining the proper function of microtubules and preventing the aggregation of tau protein, these drugs aim to slow down or halt the progression of Alzheimer's disease. The potential benefits include preserving neuronal integrity, reducing cognitive decline, and improving overall brain function in affected individuals.
However, it is important to note that the effectiveness and safety of these experimental drugs are still being studied, and they have not yet been approved for clinical use. Ongoing research is vital to further understand the mechanisms involved and to develop effective treatments for Alzheimer's disease.

Could an insoluble precipitate of an ionic compound pose a danger to theenvironment? Explain your reasoning.
The insoluble precipitate of ionic compound can pose great threat to the environment.
Insoluble precipitate is a solid substance formed during a chemical reaction. The precipitate of ionic compounds can cause danger to the environment as it is not degraded and hence can cause reactions that form toxic products.
The effects of insoluble precipitate on the environment are various. It can make soil less rich in nutrients that will then affect the quality and yields of plants. If the precipitate is present on the surface of plants, which is then ingested by humans, it can cause diseases in humans as well. It can cause eutrophication of waterbodies, therefore affecting the lives of aquatic species.
