Answer:
A) True
Explanation:
The Metacognitive strategies help students develop an appropriate plan for learning information.
Answer:
For example, an atom with 6 of 8 electrons in its outer shell will try to gain 2 electrons so its outer shell is full. Ionic bonding occurs when one element donates an electron (or electrons) to another so that both elements will have a full outer shell. As the attractions bring the atoms together, electrons from each atom are attracted to the nucleus of both atoms, which “share” the electrons. The sharing of electrons between atoms is called a covalent bond, which holds the atoms together as a molecule.

Answer:
Kupffer cells, also known as stellate macrophages due to their particular structure while viewed under a microscope, were first identified by scientist Karl Wilhelm von Kupffer, after whom the cells were named, in 1876.
These cells, whose origin is in the yolk sack during fetal development, later on move to the liver where they will stay and further differentiate into their mature versions.
These cells are part of the liver cells, and are found particularly on the walls of the sinusoids, where they perform their two most important tasks. First, these cells are part of the immune system, as they are essentially macrophages. However, their role is pretty unique, as they are responsible not just for phagocytosis of invading bacteria, and other pathogens, and initiating immune responses, but also, this cell plays a role in decomposing red blood cells who are dying, and taking up the hemoglobin from them to further break that into reusable globin, and the heme group, from which iron is further extracted to be re-used and also to create bilirrubin, a part of bile.
Finally, these cells have been found to be connected to hepatic cirrhosis, as in their process of detoxifying ethanol, they produce toxins that force the liver cells to produce collagen, and thus to become fibrous.
Answer:
The answer is letter c, The structure of individual neurons.
Explanation:
Brain-imaging technique- <u><em>this comprises of different techniques for analyzing the brain's activities as well as structure, function and other problems.</em></u>
There are many brain-imaging techniques such as <u>Positron Emission Tomography or PET,</u> which traces the part of the brain that is activated during specific tasks as well as the localization of brain activity in response to a specific stimulus. These areas are seen with high radioactivity.
Patterns of blood flow in the brain can be detected by using <u>MRI (Magnetic Resonance Imaging) test.</u> There is an increase in blood flow to areas in the brain with high activity level.
With the explanation given, it shows that letter c is the only choice that the brain-imaging techniques cannot determine.
