The right answer is C.
Meiosis and fertilization contribute to the stability of the species.
Meiosis ensures the passage of the diploid phase to the haploid phase. It follows a phase of DNA replication and consists of two successive divisions, the second is not preceded by a duplication of DNA. These two divisions lead, from a diploid mother cell (2n chromosomes), to four haploid daughter cells, the gametes (n chromosomes).
Meiosis and fertilization are at the origin of genetic mixing.
During meiosis, intra- and interchromosomal mixing occurs (inducing a genetic diversity between the daughter cells, and they are systematically different from their mother cell).
*Intrachromosomal mixing, or crossing-over recombination, takes place between paired homologous chromosomes during the prophase of the first meiosis division;
*Interchromosomal mixing is due to the independent migration of the homologous chromosomes of each pair during anaphase of the first division. It therefore concerns chromosomes reworked by the intrachromosomal mixing that preceded it.
Answer:
Tidal volume is air *around one half liter*. Group of answer choices forcibly expelled after normal expiration inhaled after normal inspiration exchanged during normal breathing remaining in the lungs after forced expiration
Explanation:
Have a great day!
The correct answer is B, diaphragm relaxes, volume decreases, pressure increases and air moves out of the lungs.
Pressure and Volume are inversely related
Answer:
Polycistronic mRNA:
Polycistronic mRNA may be defined as the mRNA that has the ability to code multiple proteins from a single mRNA molecule. This type of mRNA is generally found in prokaryotes.
Operon:
Operon may be defined as the DNA functional unit that contains the cluster of genes. These gene are regulated by the single promoter. These operon system are generally found in prokaryotes.
Regulon:
Regulon may be defined as the group of genes that acts as a single regulatory unit. The protein expressed by regulon can acts as a activator or repressor. These are generally found in eukaryotes.
