Answer:
Tongue-rolling is dominant, and both parents were heterozygous
Explanation:
Tongue rolling is a type of variation in human beings. When allelic genes are not identical as in Tt, the condition is referred to as heterozygous. An individual with such a genotypic condition is referred to as a heterozygote.
Both parents had a genotype of Tt and they could roll their tongues because T is dominant over the t gene.
T t
T TT Tt
t Tt tt
TT : Tt : tt
1 : 2 : 1
In a heterozygous parent Tt, the chance of producing T gamete from both parents is each 1/2 each. Similarly the chance of forming t gamete is 1/2. Therefore, the chance of gamete T and t fusing to get genotype Tt is 1/2*1/2=1/4.
The ratios of phenotypes are 3/4 will be able to roll the tongue and 1/4 will not be able to roll the tongue.
The mode of inheritance was monohybrid inheritance since one characteristic like tongue-rolling is controlled by a single pair of hereditary factors contributed by both parents.
Answer: The Central Nervous System and The Peripheral Nervous System
The remainder when p(x) = -2x⁵+x⁴+5x³+4x+1 is divided by (x-2) is 1.
To solve the question above, we make use of the remainder theorem.
Remainder Theorem: It states that if a function F(x) is divided by (x-a), the remainder is F(a).
From the question,
Given:
- Dividend ⇒ p(x) = -2x⁵+x⁴+5x³+4x+1
- Divisor ⇒ (x-2)
in view of the above and applying the Remainder theorem, The remainder will be p(2)
- p(2) = -2(2⁵)+2⁴+5(2³)+4(2)+1
- p(2) = -64+16+40+8+1
- p(2) = 1
hence the remainder when p(x) = -2x⁵+x⁴+5x³+4x+1 is divided by (x-2) is 1

Proteins that are functionally less important for the survival of an organism generally evolve faster than more important proteins.
Proteins serve as the building blocks for all of life's essential processes. The proteins evolve along with the genes that create them, adding new functionality or features that may potentially result in the development of new species.
The mutation of amino acid-coding nucleotides and the stabilization of novel variations in the population are the two phases required for protein evolution.
The stability of a protein's folded structure, how well it prevents aggregation, and how well it is chaperoned all affect how quickly it evolves. According to the studies, the degree of a protein's expression has a greater influence on its evolutionary rate than does the protein's functional significance.
