Energy from sunlight is being used in an indirect way for walking the dog. Plants photosynthesize in which they absorb energy from sun and convert it into chemical energy, which is stored in organic product formed as a result of photosynthesis. When this organic compound is consumed by us, we use the chemical energy stored in that food to mechanical energy for walking the dog. Hence, the energy to walk the dog comes from sunlight.
Multicellular organisms are reffered to as eukaryotes while unicellular organisms are reffered to as prokaryotes. Among the kingdoms, kingdom animalia and plantae are kingdoms in which microorganisms are considered as eukaryotes.
Answer:
C. parvum takes energy from glucose which is present in the digestive tract after the process of glycolysis.
Lactate dehydrogenase which is responsible for the conversion of lactate into pyruvate molecule.
Explanation:
C. parvum is a protozoa that lives as a parasite in the digestive tract of animals. They take nutrients from the cell which are present in the form of glucose. C. parvum uses a specific type of enzyme i. e. lactate dehydrogenase which is responsible for the conversion of lactate into pyruvate and also helps in the production of ATP through glycolysis process. In this process, the glucose molecule is broken down into two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water. So C. parvum takes ATP from that way from the host cells.
The correct answer is by using the antagonist.
The antagonist is a molecule that blocks a biological response by binding to the receptor. So, you add antagonists to the receptors you want to determine and see which antagonist blocked the response. By blocking the specific response you can get the answer what receptor it was.
