Answer the following question given this paragraph: The Levels of Organization To study the chemical level of organization, scientists consider the simplest building blocks of matter: subatomic particles, atoms and molecules. All matter in the universe is composed of one or more unique pure substances called elements, familiar examples of which are hydrogen, oxygen, carbon, nitrogen, calcium, and iron. The smallest unit of any of these pure substances (elements) is an atom. Atoms are made up of subatomic particles such as the proton, electron and neutron. Two or more atoms combine to form a molecule, such as the water molecules, proteins, and sugars found in living things. Molecules are the chemical building blocks of all body structures. Q: All matter in the universe is composed of one or more unique pure substances called what? A:
OPTIONS:
- atoms
- molecules
- compounds
- elements

Answer: elements

Question: Answer the following question given this paragraph: Pancreatic Secretion Regulation of pancreatic secretion is the job of hormones and the parasympathetic nervous system. The entry of acidic chyme into the duodenum stimulates the release of secretin, which in turn causes the duct cells to release bicarbonaterich pancreatic juice. The presence of proteins and fats in the duodenum stimulates the secretion of CCK, which then stimulates the acini to secrete enzyme-rich pancreatic juice and enhances the activity of secretin. Parasympathetic regulation occurs mainly during the cephalic and gastric phases of gastric secretion, when vagal stimulation prompts the secretion of pancreatic juice. Usually, the pancreas secretes just enough bicarbonate to counterbalance the amount of HCl produced in the stomach. Hydrogen ions enter the blood when bicarbonate is secreted by the pancreas. Thus, the acidic blood draining from the pancreas neutralizes the alkaline blood draining from the stomach, maintaining the pH of the venous blood that flows to the liver. Q: The entry of acidic chyme into the duodenum stimulates the release of what? A:
OPTIONS:
- progesterone
- gastrin
- oxygen
- secretin
Answer: secretin

input with options: Answer the following question given this paragraph: There are two ways to control the current in a circuit. Since the current is directly proportional to the potential difference and inversely proportional to the resistance, you can increase the current in a circuit by increasing the potential or by decreasing the resistance. Q: Besides increasing the potential, how else can you increase current in a circuit? A:
OPTIONS:
- increasing the resistance
- increasing the heat
- decreasing the heat
- decreasing the resistance
output: decreasing the resistance

Q: Answer the following question given this paragraph: The three germ layers are the endoderm, the ectoderm, and the mesoderm. Cells in each germ layer differentiate into tissues and embryonic organs. The ectoderm gives rise to the nervous system and the epidermis, among other tissues. The mesoderm gives rise to the muscle cells and connective tissue in the body. The endoderm gives rise to the gut and many internal organs. Organogenesis Gastrulation leads to the formation of the three germ layers that give rise during further development to the different organs in the animal body. This process is called organogenesis. Organs develop from the germ layers through the process of differentiation. During differentiation, the embryonic stem cells express specific sets of genes that will determine their ultimate cell type. For example, some cells in the ectoderm will express the genes specific to skin cells. As a result, these cells will take on the shape and characteristics of epidermal cells. The process of differentiation is regulated by location-specific chemical signals from the cell's embryonic environment that sets in play a cascade of events that regulates gene expression. Q: Which germ layers are essential for animal embryos to grow and develop into a body? A:

OPTIONS:
- histone and melatonin
- keratinocytes , ectoderm , mesoderm
- cytoplasm and chloroplasm
- endoderm, ectoderm, mesoderm

A: endoderm, ectoderm, mesoderm
