Answer:
Nucleus
Explanation:
Chromatids are the linearly arranged condensed structure of genetic material in the cell. The chromatids are observed after the parent cell are divided into the daughter cells.
During cell division, the cell divides, their chromosomes separate and gets accumulated at the poles of the cell. These chromatids are naked that is floating in the cytosol but the characteristics feature of the eukaryotic cell is the presence of a double membrane organelle which can protect the genetic material called the nucleus.
Thus, nuclear envelope or nucleus gets reformed around the chromatids.
Answer:
The correct option is D) They will shrink.
Explanation:
An isotonic solution can be described as a solution that has a balance of solutes and solvents inside and outside a cell. As a result, no concentration gradient is developed. Hence, there is no transfer of solutes or solvents in an isotonic solution.
But when solutes will be added into the solution a concentration gradient will develop. There will be more molecules of solutes outside the cell as compared to the inside of the cell. As result, the solvent will move outside the cell to maintain a balance. Hence, the cells will shrink.
Answer: The correct answer is- gymnosperms and angiosperms.
Phylogenetic tree is a diagrammatic representation that depicts the evolutionary relationship among different group of species. In other words, it is used to interpret the relatedness among different species and how they have descended from a common ancestor.
The tips in the phylogenetic tree represents the taxon ( or particular group of species) that are descended.
In the given tree, gymnosperms and angiosperms have evolved most recently because they correspond to the most recent branches having the immediate common ancestor at the topmost level as compared to the immediate common ancestor of other taxon.
Thus, gymnosperms and angiosperms is the right answer.
Answer:
A. DNA repair
Explanation:
The p53 protein acts as a tumor remover by controlling a set of genes required for the cell division. This protein protects the genome by <u>restricting abnormal cells to proliferate</u> avoiding the replication of damaged DNA. The first resource the protein uses and prometes is DNA repair and if the DNA has irreparable damage, t<u>he last resource used by this protein is</u><u> apoptosis</u>.
