Explain why your model improves upon the student’s original model. How would your model help someone who was learning about photosynthesis for the first time? Plato question
Answer:
Due to inclusion of more steps of photosynthesis.
Explanation:
My model is more advance than the student's original model which provides more information about the process of photosynthesis to the learners by explaining various parts of photosynthesis. My model presents the various steps of photosynthesis in a very efficient way with the help of including some extra parts. The student's original model is not more advance so it can't provides more information about the process of photosynthesis so that's why my model provides more information about photosynthesis.
Answer:
This model shows all the major molecules involved in the Calvin cycle and how they change at each stage of the process. This added detail would clarify that the Calvin cycle is a series of complex steps. The student’s original model didn’t show this breakdown at all, and it shows only the final products. This model also shows the number of each molecule created, which the original model doesn’t do.

I hope this will help you if not then sorry, have a great day :)do fertilised eggs divide to form a foetus
Answer:
yes
Explanation:
the chromosome number of the egg and and sperm are halved ,and are then joined together. the fusion of the the nucleus of the haploid male gamete with the haploid female gamete is referred to as fertization and the product of fertilization is zygote.
The diploid single zygote then divides repeatedly and develops to produce the offspring whose somatic cells are diploid.The zygote is the initial stage in baby development. It is also known as a fertilized ovum formed from the union of the sperm cell and the egg cell. Foetus refers to the final stage in baby development.

Answer:
Muscle cells are most likely affected by the poison.
define the term excretion.
state an excretory product that is passed out trough the lungs.
outline the role of the liver in excretion.
Answer:
Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin.
Carbon dioxide
The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic.

What causes an ionic bond to form between sodium and chlorine?
Answer:
The loss of an electron
Explanation:When sodium (Na) and chlorine (Cl) are combined, the sodium atoms each lose an electron, forming cations (Na+), and the chlorine atoms each gain an electron to form anions (Cl−
Answer:
"Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons. ... If sodium can transfer it's "spare" electron to chlorine, both atoms will satisfy their full outer shell requirements, and an ionic bond will be formed."

A mitosis inhibitor is a medication that is designed to prevent mitosis in certain cells. Why would these be helpful in the treatment of tumors
Answer:
because cancer cells are able to grow and eventually spread through the body (metastasize) through continuous mitotic division. Thus, cancer cells are more sensitive to inhibition of mitosis than normal cells.

How do mitochondria differ from chloroplast
Explanation:
Mitochondria and chloroplast are organelles found in a plant cell. However, chloroplast is absent in an animal but mitochondria is found in both.
Mitochondria generates energy for the cell in the form of ATP using oxygen and nutrients while Chloroplast is the site for photosynthesis in a plant cell.
Answer:
MitochondriaKnown as the powerhouse of the cell, it is responsible for energy metabolism and cellular respiration.chloroplastLarger and much more complex than a mitochondrion, it is the site where photosynthesis takes place.Hope this helps you ❤️MaRk me as brainliest ❤️^_^What is the correct structure of ATP? A. Ribose sugar, Adenine base, 3 Phosphate groups B. Triglyceride head, Ribose sugar, 3 fatty acids C. Ribose sugar, Phosphate group, Nitrogen Base D. Deoxy Ribsose sugar, Adenine base, 3 Phosphate groups
Answer:
The correct structure of ATP is
A. Ribose sugar, Adenine base, 3 Phosphate groups
Explanation:
The structure of ATP is a nucleotide, consisting of a nitrogenous base (adenine), a ribose sugar, and 3 serially bonded phosphate groups.
While working with cultured mouse cells, a researcher unknowingly treated the cells with a mutagen that causes the deletion or insertion of individual nucleotides in DNA. Subsequently, she isolated and cultured a single cell from this group. She noticed that the progeny of this cell were not producing a certain protein and that this affected their survival. The mutation would be most harmful to the cells if it resulted in ______.
Answer:
The correct answer is - a single nucleotide insertion near the start of the coding sequence.
Explanation:
Insertion mutations are the mutation that takes place when there is an extra nucleotide is added to the DNA strand during replication and causing the particular protein translation or inhibits the translation if present at the start codon.
It did not allows the translation in this sequence, Deletion, and insertion both are a dangerous mutation that causes the production of unwanted protein or not producing the protein and if this protein is essential for surviving it will lead to cell death.
