Explanation:
While mitosis makes two identical cells with the same numbers of chromosomes, meiosis makes four unique daughter cells, from which every cell has half of the number of the chromosomes as the parent cell.
Meiosis is the specified form of cell division, making the reproductive cells, like sperm and egg cells, for example.
Answer:
Mosses
Explanation:
Mosses are the category of plants that does not have vascular tissue or seeds while angiosperm, gymnosperms, and ferns have vascular tissues and seeds.
Due to absence of vascular bundles or veins, the mosses also lack stems, true roots, and leaves. some of the examples of mosses are: liverworts, hornworts, and Ricceia natans etcetera.
Hence, the correct answer is "Mosses".
Because the black mouse is homozygous.
The black color in mouses is dominant, and the brown is recessive. When a parent is homozygous, their children need to have their gene. Because in this case the trait is black, it dominates brown in all children.
The table is BB×bb = Bb, Bb, Bb, Bb = 100% heterozygous genotype = 100% black phenotype.
Answer:
D. Binding of p53 to Mdm2
It has nothing to do with Xray irradiation.
Explanation:
Mdm2 is a protein regarded as the main regulator of tumor suppressor protein P53. P53 Inactivation by mutation is seen as one of the most frequent alterations in tumors that affects humans.
The central binding p53 site of Mdm2 encloses amino acid. The binding of p53 to the central Domain is strengthened after the process of phosphorylation of the central Mdm2 domains.
