The fallopian tubes, also known as uterine tubes.
The inferior most, or the lowest, sinus cavity is called the maxillary sinus. It is also the largest sinus cavity and it drains into the middle of the nose. The maxillary sinus is located above the upper jaw and is easily visible on x-rays above the premolar and the molar teeth.
The symptoms of sinusitis include headaches near the sinus and discharge of foul-smelling mucus.
A heterogeneous mixture composes of non- uniform components, so the concrete would be the answer, because you can tell the components from one another.
Answer:
The correct answer is: a.
Explanation:
- A Diploid organism possess two copies ( also called alleles) of each autosomal gene, of which one copy of the gene is obtained from one of its parents and the other copy from its other parent.
- During the process of replication, one of the alleles of the GTPase encoding gene undergoes a mis-sense mutation.
- A Mis-sense mutation can be defined as a non-synonymous mutation in which one of the nucleotide in the sequence of the gene gets altered such that it causes a change in the amino acid encoded by the codon (triplet nucleotide message encoding for a single amino acid) formed by the mutated nucleotide. A single amino acid change in the protein, if occurs in the functional site of the protein, can render a protein non-functional.
- Hence, the mis-sense mutation in one of the alleles encoding for the GTPase gene causes the resulting protein produced from the mutated allele to have drastically reduced function (1%).
- A heterozygous cell is one which has one copy of the normal allele and the other copy of the mutated allele of the GTPase encoding gene.
- As one copy of the normal GTPase allele is present in such an individual, it can produce the normal GTPase protein that can assist in the process of cell growth and division.
- Hence, the phenotype(expressed character) of the heterozygous cell will not be affected due to the mutation and it will be able to grow and divide normally.
