By activating a process that destroys cyclin components, the MPF protein complex turns itself off.
The MPF protein or the Maturation or Mitosis Promoting Factor depending on who you ask is an intricate word for the cyclin B/ CDK1 complex, which is present in the M phase, it is required in order for the entry to the M phase.
Answer:
Since the gene mutates at a rate of 0.76 base pairs every 17.1 million years, to find out the time it would take for 1 base pair to mutate can be calculated by dividing 17.1 million years by 0.76
17,100,000 ÷ 0.76 = 22.5 million years
The following equation can be used to describe this:
μ = [(r2/N2) − (r1/N1)] × ln (N2/N1) = (f1 − f2) × ln (N2/N1)
r1 = the observed number of mutants at time point 1
r2 = the observed number of mutants at the next time point
N1 and N2 are the numbers of cells at time points 1 and 2
Hope that answers the question, have a great day!

Answer:
A) Chromosomes are made of DNA
C) Alleles are the different forms of a gene that can exist
D) Chromosomes contain genes that control the inheritance of traits.
Explanation:
Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.
Answer:
The soft palate reflexively opens the nasopharynx to allow the passage of food is called bolus is not true. During the pharyngeal stage, the soft palate elevates and contacts the lateral and posterior walls of the pharynx, closing the nasopharynx at about the same time that the bolus head comes into the pharynx. Soft palate elevation prevents bolus regurgitation into the nasal cavity
Explanation:
When food is ingested into the mouth, the tongue carries the food to the post-canine region and rotates laterally, placing the food onto the occlusal surface of lower teeth for food processing.During food processing, food particles are reduced in size by mastication and softened by salivation until the food consistency is optimal for swallowing.during food processing, the tongue and soft palate both move cyclically in association with jaw movement, permitting open communication between the oral cavity and pharynx.When a portion of the food is suitable for swallowing, it is placed on the tongue surface and propelled back through the fauces to the oropharynx.. The area of tongue-palate contact gradually expands backward, squeezing the triturated food back along the palate to the oropharynx.Pharyngeal swallow is a rapid sequential activity, occurring within a second.During the pharyngeal stage, the soft palate elevates and contacts the lateral and posterior walls of the pharynx, closing the nasopharynx at about the same time that the bolus head comes into the pharynx. Soft palate elevation prevents bolus regurgitation into the nasal cavity.
