Answer:
Experimental group
Explanation:
An experimental group or the treatment group is the group or test subjects that receives a treatment in an experiment. The results is contrasted against a control group which do not receive the treatment in an experiment.
In this case, the people who ate the Olestra potato chips were the are the test subjects in the experimental group used to find answers to some varaibles in the experiment.
Answer: Their supporting structure would be most likely the MUSCULOSKELETAL SYSTEM of the multicellular organisms.
Explanation:
The musculoskeletal system found in multicellular organisms are made up of structures which provides support, protection and allows for various movements. These structures include:
--> Muscles
--> Cartilage
--> Ligaments
--> Tendons and
--> Joints
Furthermore, Microtubules and microfilaments are the major components of cytoskeleton. They are the structures that gives a cell it's shape and helps organise it's parts. As described in the question, they are elongated structures that cross the cell, giving SUPPORT to the cell, and carries organelles and objects throughout the cell.
Therefore, since the Microfilaments and Microtubules provides support and shape at the cellular level it can be most likened to the musculoskeletal system of multicellular organisms which performs the same functions.
The answer would be a because the jet stream is very cold and come down to the water like a magnet sort of and keeps the top of the water cold so there for you have a cold water current on the top of the water so the answer is )A
Ingestion of foreign substances by macrophages and yeast cells by an amoeba is known as <u>Phagocytosis</u>
<u>Explanation:</u>
Phagocytosis that is the name given to the process of ingestion of foreign particles by macrophages. In human body the white blood cells does this function. Macrophages is found in all the tissues. Any foreign particle entering the body is engulfed by this process hence protecting the organisms.
Once a bacteria enters the body it is at once detected and recognised as the foreign particle. Then it is attached to the phagocyte. Then it is engulfed into a vesicle called phagosome. Then this is killed by the process of phagocytosis.
