The area of the frontal lobe that is devoted to the production of fluent speech is the Broca's area. It contains neurons that is involved in speech production and language comprehension. It is classified into two parts namely the pars triangularis and the pars opercularis.
Answer:
In Meiosis, cells are divided twice to the give haploid cells ( four cells) with half the number of chromosomes in the original cell, while in mitosis, cells only divide once to give identical cell with the same number of chromosomes as its origin.
Explanation:
Meiosis is a process where a cell divides to give four cells, with the chromosomes half of that of the original cell. This cell division helps produce your genital cells like sperm and female egg. There are nine stages in meiosis.
Mitosis is a process of cell division where a single cell divides just once to produce two identical cells with the same number of chromosomes as the original cell.

Explanation:
1. As shown in the punnet square below, the offprings can have the following genotypes; AA, AO. AB, and BO. The phenotypes of the offsprings will therefore have blood types; A , AB and B.
2. A pedigree is a tree that shows the family history of an individual. In the lineage, one can discover that a particular disorder is transmitted by a certain gender, which is most often the males. This is how sex-linked disorders are indentified.
3. The Y chromosoms have very few genes and does not match the X chromosome allele for allele. Therefore a recessive gene on the X chromosome in males is likely to be expressed than in females because females have an extra X crhomosome.
4. The dominant allele is always expressed over the recessive one even when both are present (heterozygous) in an individual. Only when both aleles are recesive will the recessive trait be expressed.
5. Incomplete dominance means none of the alleles have complete dominance over the other. This means that both are expressed and the expressed traits is an intermediate of the individual traits of the alleles.
Binomial nomenclature ("two-term naming system") also called binominal nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, binominal name or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part – the specific name or specific epithet – identifies the species within the genus. For example, humans belong to the genus Homo and within this genus to the species Homo sapiens.
