The name of the process that needs energy (adenosine triphosphate, or atp) for nutrients that were digested to be absorbed through the small intestinal wall into the bloodstream or lymphatic system is called active transport. This process involves the movement of particles in a membrane from a lower concentration to a higher concentration with the aid of an external source like energy or enzymes.
Answer:
The right matching of the scenario in the question are as follows:
1. OBSERVATION: Josh noticed that Julie ordered extra hot peppers and added hot sauce to her food
2. QUESTION: Josh wondered how to cook spicy Mexican food.
3. HYPOTHESIS: Josh decided jalapenos would be a good ingredient to add spice to the recipe.
4. EXPERIMENT: After chopping the jalapenos, he slowly added some to the enchilada filling, tasting as he went until he thought it was spicy enough.
5. RESULTS: Julie thought the enchiladas were delicious and exactly the right level of spice.
6. CONCLUSION: Josh determined that since Julie liked the meal, adding jalapenos to the recipe was a good way to make it spicy.
Explanation:
Scientific method is an organized steps of procedures that scientists used to study and gather knowledge about different phenomenons. The systematic steps of scientific method start with observation, the observed phenomenon usually make a scientist to ask questions that he doesn't have an answer to. This will prompt him to formulate an hypothesis and set up an experiment to see if his hypothesis is true or not. The result he obtains from the experiment will determine the type of conclusion he will make about his earlier observation. By following these steps, scientists usually obtain useful information that bring progress and advancement to humanity.
You are testing for the presence of starch: Iodine dissolved in an aqueous solution of potassium iodide - reacts with starch producing a deep blue-black color. This reaction is the result of the formation of polyiodide chains from the reaction of starch and iodine.
Answer:
Endocytosis is a form of active transport hence require enegry powered by ATP. The amoeba needs to change shape and engulf and envaginate the particle and then use vessicle transportation to get the materials into the cell. This requires that the cytoskeleton - composed of tubules and filaments - contracts and relax accordingly. This requires energy by ATPs just like the myosin and actin of muscle.
Phagocytosis, another form of endocytosis, is used by some cells such as immune cells to engulf foreign material and then destroy them by use of lysozymes. This is how phagocytes protect the body from invaders.
