<h3><u>Answer;</u></h3>
<em>2 atoms of nitrogen </em>
<h3><u>Explanation;</u></h3>
- A compound is a substance that is made up of different types of atoms from different elements. For example water is a compound made up of hydrogen and oxygen atoms.
- In this case; Ni(NO₃)₂, is an example of a compound. It is <u><em>made up of 1 nickel atom, 2 atoms of nitrogen, and six atoms of oxygen</em></u>.
Answer:
This flaw of thinking is called the HINDSIGHT bias.
Explanation:
<em>"We don't really know the result, but we think as though we do." </em>
The Hindsight bias, <em>creeping determinism</em>, or <em>knew-it-all-along phenomenon</em>, is the <u>assumption of an individual regarding an event that have already occurred as expected, as if he knew it even before the event took place</u>. This leads to the person believing they have a high sense of certainty of what the outcome would really be, even before the culminating of the event. This usually <u>results to </u><u>overconfidence or overestimation</u><u> in recalling the sequence of events before the predicted bias</u>.
<h3>There are 3 levels of hindsight bias </h3>
- Memory distortion - unable to recall the previous judgment (<em>"I said it would happen"</em>).
- Inevitability - the event must happen even with or without the circumstances (<em>“It had to happen”</em>).
- Foreseeability - that belief and confidence wherein results of the event were already anticipated, even way before the event culmination (<em>“I knew it would happen”</em>).
Answer:
E) Improve membrane fluidity
Explanation:
Cholesterol constitutes the basic structural element of the skeleton of cell membranes. Without their reinforcement, the membranes would become extremely fluid and lose their consistency. Cholesterol is found in the esterified membranes in its hydroxyl group (OH): with fatty acids, mainly oleic and linoleic, or as cholesterol sulfate. The cholesterol-sulfate polar group is disposed on one of the faces of the membrane that interacts with other polar groups in that area, while its bulky hydrophobic portion is embedded between the apolar parts of the lipids that form the membrane skeleton and They fulfill many other functions, among which the reduction in the permeability of protons and sodium ions, and their participation in signal transmission. Cholesterol is also essential in phagocytosis processes carried out by cells to capture many nutrients and, in general, for the function of cleaning up organic waste produced by macrophages.
The membranes must have a fluid structure so that the integrated proteins can move "horizontally" to interact with their ligands and with other proteins. The fluidity is given by unsaturated fat. With the excess of saturated fat, the membranes become rigid, but only with the necessary unsaturated fat the membranes are extremely fluid and very sensitive to temperature changes. Cholesterol stabilizes the structure of the membranes; In order for them to have the correct structure, they must have the correct proportions of saturated, unsaturated fats and cholesterol. The membranes produced in the laboratory without cholesterol are unstable to temperature changes, drastically modifying their fluidity against the small temperature changes that occur in the physiological range.
In addition to its functions in cell membranes, cholesterol is an important product that metabolism uses as a raw material to make other compounds:
*Bile salts
*Sex hormones
*Hormones of the adrenal cortex (corticosteroids)
*Vitamin D (Calciferol)
Hey there! Your answer would be:
The new technology allows detection of a structure that could not be detected previously.
I hope this helps!
Answer:polysaccharide
Explanation:
A starch macromolecule is a polysaccharide composed of thousands of glucose units. glucose molecules can be added to starch by a condensation reaction.
