How many atoms in all are in a molecule of serotonin?
Answer:
10 carbon (black), 12 hydrogen atoms (white), 2 nitrogen atoms (blue), 1 oxygen atom (red)
Explanation: Serotonin is a molecole composed of all of these atoms
A molecule of serotonin has 25 atoms in total, and these atoms are arranged in a specific pattern to give serotonin its unique chemical and biological properties.
What is serotonin?Serotonin is a neurotransmitter, which means it is a chemical that is used by the nervous system to transmit signals between nerve cells. It is also a hormone that regulates various physiological processes in the body. The chemical formula for serotonin is [tex]C_1_0H_1_2N_2O,[/tex] which indicates that it contains 10 carbon atoms, 12 hydrogen atoms, 2 nitrogen atoms, and 1 oxygen atom. The molecule of serotonin consists of a benzene ring with two substituents: an amino group and a hydroxyl group (-OH). The amino group and hydroxyl group are attached to adjacent carbon atoms in the benzene ring, and the nitrogen atom is attached to one of the carbon atoms in the amino group.
Hence, a molecule of serotonin has 25 atoms in total, and these atoms are arranged in a specific pattern to give serotonin its unique chemical and biological properties.

Which student, if either, is most correct in their claim regarding the ATP/ADP cycle?
A. Brianna's claim is correct - the removal of a phosphate group (or the breaking of
a chemical bond) supplies a great deal of energy from the cell and the ATP/ADP process is not continuous.
B. Neither student is completely correct. Oscar is correct in that this process is a
cycle and Brianna is correct in that the removal of the phosphate group supplies the most energy
C. Oscar's claim is correct - the addition of a phosphate group (or the making of a
chemical bond) supplies a great deal of energy from the cell and the ATP/ADP
cycle is continuous.
D. Both students are correct - Oscar's claim is correct for the process of
photosynthesis and Brianna's claim is correct for the process of cellular
respiration.
Answer:
A
Explanation:
because it is the the ATP/ ADP does not process which is true.
Briefly summarize the difference between Exergonic reactions and endergonic reactions
Answer:
Exergonic and endergonic reactions result in changes in Gibbs free energy. In exergonic reaction the free energy of the products is lower than that of the reactants; meanwhile, in endergonic the free energy of the products is higher than that of the reactants.

Which of the following processes produces the most ATP? a aerobic respiration b glycolysis c alcoholic fermentation d lactic acid fermentation
Answer:
b) glycolysis
Explanation:
Up to 36 ATP can be produced from one glucose molecule through aerobic reactions. Therefore, option (A) is correct.
What is aerobic respiration?Aerobic respiration supplies energy to fuel all cellular functions. The reactions result in the production of ATP, which can then be put to use to power other life-sustaining processes, such as growth, repair, and maintenance.
The release of energy that was stored in carbohydrates and lipids during photosynthesis and the subsequent availability of that energy to living organisms is the purpose of the series of enzyme-controlled events known as aerobic respiration.
Glycolysis, the Krebs cycle and respiratory electron transport contribute to the production of 36 ATP for every molecule of glucose that is used up during aerobic cell respiration.

Identify minerals extracted in Haiti
and describe what is done with
them.
Answer: Haiti is mainly know for their minerals! the main minerals extracted are: cooper, silver, and GOLD. Haiti has many many gold farms, markets, etc. HOWEVER this is a very poor area, as people here live off of only about 2 dollars per day. They could take this wealth and put it towards the people, roads, and construction, as they had an earthquake that killed many many people, and destroyed much. If you mean what they do with gold, they take the gold from farms, and mine it underground. They then sell it for money as this is a poor area as said before!

Farmers brought nutria, a type of large rodents, from South America to North America in the 1990s. They wanted to raise the rodents for their fur. Some of these rodents escaped into the wild and became a major pest in the Gulf Coast and Chesapeake Bay regions. Grasses and shrubs in these regions are vital, because they provide food and shelter for many species. They also help in preventing soil erosion. The nutria are eating up all the grasses and shrubs, which affects the food cycles of these regions. The entire ecosystems are being disrupted.
Moreover, nutria pose a direct threat to humans. These rodents are an effective vector for carrying parasites that can cause disease in humans. They also damage property. The burrows created by nutria can damage dams and building foundations as well as cause erosion near streams and lakes.

the answer from pluto/edmentum
Answer:
The apple snail is a native species of Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Southeast Asia legally imported this alien species to use it as a protein source. Later, this species was brought to places like Hawaii as a source of food.
Like most, if not all, invasive species, the apple snail outcompetes native species for resources. This is because it reproduces rapidly (laying hundreds of eggs every few weeks) and lacks predators. As a result, the snails spread rapidly to aquatic biomes and modify the natural balance of aquatic ecosystems.

James is conducting an experiment to test the effect of insecticides on frogs. He gives one group of frogs 10 cc of the insecticide and 0 cc of the insecticide to the other group of frogs. After 5 days, the effects of the insecticide are collected. what is the independent variable and dependent variable
Answer:
Independent variable: amount of insecticide
Dependent variable: effects of insecticide on frogs
Explanation:
Dependent variable in a research experiment, is the variable that is being studied, tested and measured by the researcher, while the independent variable is the variable that causes the dependent variable to change, when it is varied.
In this case, the amount of insecticides that is varied in quantity, is the independent variable that the researcher manipulates, while the independent variable is the effects caused by these varied amount of insecticide on frogs, which is tested and measured.
