Answer:
a. The letters Na with one dot
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.
Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valency can be defined as a measure of the combining power of a chemical element with other atoms to form a molecule or chemical compound.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Thus, valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others.
Sodium is a chemical element that is found in group (1) of the periodic table and as such it has 1 electrons in its outermost shell. Also, the chemical symbol for Sodium is Na and it has one (1) valence electron.
A Lewis structure can be defined as a structural representation of an atom or molecule by using a dot to show the position and distribution of electron(s) around the atom or molecule.
Hence, the letters Na with one (1) dot is a correct Lewis structure diagram for Sodium (Na) because it has just one (1) valence electron in outermost shell.
For example, the Lewis structure diagram for Sodium (Na) is •Na.
The side of the epithelia facing the extracellular fluid surrounding the intestine is the<u> </u><u>basolateral </u><u>side.</u>

- Different amino acid transport mechanisms exist in the intestine basolateral membrane than in the brush border membrane.
- The portion of the plasma membrane at the basolateral side of the cell that confronts other cells and the connective tissue beneath is known as the basolateral cell membrane.
- The membrane at the cell's base and sides is referred to as basolateral.
- A barrier between the cell and the blood or other cells is created by the basolateral membrane.
- Through specialized protein transporters, the basolateral membrane's primary job is to move nutrients from the cell to the blood plasma.

Answer:
True
Explanation:
<em>The latter studies truly showed that some factors other than genetic predisposition play a role in obesity.</em>
The composition of the genome of an individual might predispose such individual to a higher risk of being obese. However, that such individual will become obese depends on some other factors, the most important being the kind of lifestyle the individual lives.
A lifestyle such as eating foods high in fat content, not eating adequate fruits, not eating eating adequate vegetables and drinking a lot of alcohol can cause someone to be obese apart from genetic predisposition.
Which processes..? There is not enough information for a solid answer to be given.
There is no definite amount that is why it is also called multiple gene inheritance
