Answer:
a. Nucleolus: The nucleolus refers to a composition, which develops with the assistance of the nucleolar organizer region present in the eukaryotes. It constitutes protein and ribosomal DNA and is a location where the generation of ribosomes takes place.
b. Centromere: The prime function of the centromere is to function as the point of attachment for sister chromatids and is a place where the attachment of chromosomes and spindle fibers takes place. The differentiation of centromere takes place at the time of mitosis and meiosis II, which helps in the distribution of chromosomal substances to the daughter cells.
c. Ribosome: The ribosome refers to the composition where different forms of RNAs, enzymes and other components help in the alignment of the primary sequence of a specific protein.
d. Chromatin: Chromatin constitutes the genetic information, which helps in sustaining hereditary information and generation of a phenotype.
e. Centriole: The centriole refers to a cytoplasmic composition, which via the help of spindle fibers assists in the migration of chromosomes at the time of meiosis and mitosis, mainly in the animal cells.
f. Mitochondria: The mitochondrion refers to a membrane-bound composition situated in the eukaryotic cytoplasm. It is the place where the production of huge amounts of ATP takes place via the process of oxidative phosphorylation.
A mid-ocean ridge is an underwater mountain system formed by plate tectonics. It consists of various mountains linked in chains, typically having a valley known as a rift running along its spine.
Answer:
What do you mean??? Makes no sense.
Answer:
C. Only one allele appears for that gene in that population.
Explanation:
This totally explains what happens during gene fixation because when it happens in a small population, it tends to make one of its allele to appear for the said gene.
Furthermore, fixation can be explained as the change in a gene pool from a situation where there exists at least two variants of a particular allele to a situation where only one of the alleles is left. In the absence of mutation, any allele must eventually be fixed or lost completely from the population. Whether a gene will ultimately be lost or fixed is dependent on selection coefficients and chance fluctuations in allelic proportions.
