Food, water, shelter, and warmth represent <u>physiological</u> needs in Maslow’s hierarchy of needs.
Abraham Maslow proposed and developed a theory in human development psychology titled "A theory of human motivation" in 1943.
Maslow's Hierarchy of Needs can be defined as a pyramid model which typically represents the fundamental (basic) needs of an individual, that are essential and required to be met before he or she can achieve complete growth, development and self-actualization.
The five (5) levels of Maslow's Hierarchy of Needs in a chronological order are;
According to Abraham Maslow the psychological needs comprises:
I. Food.
II. Water.
III. Shelter.
IV. Warmth.

B) Monocotyledons and Dicotyledons
Water is a very polar molecule.
This means there is a (slight) difference in charge between the ends of the water molecule. Water is made up of an Oxygen and two Hydrogens (H₂O). The Oxygen is a much larger atom, with 8 protons in its nucleus, whereas Hydrogen has only 1 proton.
As protons are positively charged, the oxygen has a greater positive charged, so the electrons which are negatively charged are more attracted to the Oxygen, and the bond shifts slightly towards the oxygen. As the electrons have shifted position, the negative charge has shifted position, to there is a slight negative charge nearer the Oxygen, δ⁻ (delta minus), and a slight positive charge, δ⁺ (delta plus), at the Hydrogen.
This allows strong inter molecular forces to occur, as the slightly positive Hydrogens are attracted to the slightly negative Oxygens. This force of attraction between water molecules causes them to want to 'stick together', causing a high surface tension.
So the answer is B)
In neurogenic shock, the characteristic mechanism is the reduction of sympathetic outflow from the brainstem leading to the decreased in the blood vessel tone and eventually vasodilation. In the presence of vasodilation, there will be decreased blood pressure and eventually shock. Since there is reduced sympathetic outflow, there will also be a decreased heart rate, warm skin (from the vasodilation), and dry skin (from the reduced cholinergic stimulation of the sweat glands).
The answer is B.<span>Hot air blows (from the sea) over the land because there is a high-pressure area over the sea.</span>
