Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
Answer:
nucleus- this is where all genetic information is stored.
mitochondria- where respiration occurs
cell wall- gives the cell structure and prevents it from bursting
chloroplast- contain chlorophyll which stores energy from the sun for photosynthesis
cytoplasm- where chemical reactions occur
cell membrane- controls what comes in and out of the cell.
Answer:
A. double-blind
Explanation:
Based on the scenario being described within the question it can be said that the type of trial that she has joined is known as a double-blind study. This is a type of study in which individuals are chosen randomly for each clinical intervention and the results are not given to the researchers until after the trial. This also includes any and all information that may influence the researchers behavior or thoughts on the study.
Answer:
Enzymes are produced through protein synthesis within cells. Once formed, the location of enzymes secreted varies. Enzymes may remain within the cell. An example of an enzyme that does this is DNA polymerase that helps to form new DNA. Enzymes may also become embedded in the plasma membrane. The enzyme lactase does this. It can be found in the plasma membranes of small intestine cells. As a final option, some enzymes will be secreted from the cell and used by other cells. An example of this can be seen with pancreatic production of pancreatic amylase. Once it is released from the pancreas, it participates in starch digestion in the small intestine.
Explanation:
Enzymes are a special type of protein that have the important function to catalyze chemical reactions - this means that the lack of a certain enzyme will result in an important chemical reaction not happening, or happening at a much lower rate. <u>These chemical reactions can be </u><u>anabolic </u><u>(meaning the creation -synthesis- of a molecule) or </u><u>catabolic </u><u>(which refers to the destruction -degradation- of a molecule)</u>.
For example, like the paragraph above explained, enzymes in the digestive tract have the task to convert the food that we ingest into smaller particles that can be absorbed by our intestines and used as nutrients. <em><u>If one of these enzymes were to be absent, that specific nutrient wouldn't be properly digested</u></em> - as it happens in people that are lactose intolerant (they lack the enzyme lactase, so they can't digest lactose, the sugar present in dairy products).
I believe it is called a Frameshift Mutation. Hope this helps :^)
