Morphology
Explanation:
The shape and pigment of the hairs are the morphological elements of the two hair strands.
Morphology deals with the study of the form and structure of organisms, plants and their components.
- The shape, size, color, textures, orientation are all morphological elements that can be used to draw biological comparison between things.
- It also entails the relationship between the structures with each other.
- Morphology is an expression of the genotypic make up of an organism.

Answer:
The product is significantly impure
Explanation:
In order to test for the purity of a specific sample that was synthesized, the melting point of a compound is measured. Basically speaking, the melting point identifies how pure a compound is. There are several cases that are worth noting:
- if the measured melting point is significantly lower than theoretical, e. g., lower by 3 or more degrees, we conclude that our compound contains a substantial amount of impurities;
- wide range in the melting point indicates impurities, unless it agrees with the theoretical range.
Since our compound is even 10 degrees Celsius lower than expected, it indicates that the compound is significantly impure.
The answer is C2H2 because an alkyne compound consists of a series of unsaturated hydrocarbons with a triple bond.
Answer: 1.46moles
Explanation:
Applying PV= nRT
P= 1atm, V= 32.6L, R= 0.082, T = 273K
Substitute and simplify
1×32.6/(0.082×273)=n
n= 1.46moles
