Answer:
Standard <u>anatomical
</u> position is the agreed-upon reference for body position when studying anatomy (option 2).
Explanation:
Anatomical position consists of the placement of the human body for its anatomical study, following certain norms established and accepted by convention.
- <em>The body is observed from its front face.
</em>
- <em>The members must be extended, showing their ventral surface and with a slight separation from the rest of the body.
</em>
- <em>The hands show the palms, while the feet are hyperextended showing their backs.
</em>
This position is useful to provide the description of any area of the body in a specific posture, and that can be understood even by those who do not observe.
The other options are not correct because:
<em> 1) </em><u><em>Histological</em></u><em>, refers to the study of cells and tissues.
</em>
<em> 3) </em><u><em>Superior</em></u><em>, is a directional term, indicating something located at the top of the body or closer to the head.
</em>
<em> 4) </em><u><em>Mnemonic</em></u><em> refers to the association of words used to remember names or lists of names.</em>

Answer:
b. phenotypic variation of a trait in a particular population.
Explanation:
Heritability describes a statistical measure that indicates variation in phenotypes (traits present) in a particular population.
An estimate of heritability of a trait is specific to a studied population in a determined environment, and it could change over time as circumstances often change. Heritability estimates range in a scale from zero to one.
Factors leading to this will be both ambient, and genetical. The case below exemplifies envirnoment impact.See below for a clearer view:
