b. Devonian
c. Permian
d. Vendian
2.Cloudiness of the eyes
3. Livor mortis
4. Algor mortis
Answer : Option 1) Rigor mortis.
Explanation : The parameter of rigor mortis reaches a maximum at 12 hours and is found to be gone within 36 to 48 hours.
Rigor mortis where rigor means stiffness and mortis means of death or in simple words it is postmortem rigidity, the third stage of death, is one of the major recognizable signs of death, which is mainly caused by chemical changes in the muscles post mortem, and it causes the limbs of the corpse to stiffen.
In humans, rigor mortis can occur as soon as 4 hours post mortem.
Explanation:
During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions.b This phase was formerly called the resting phase.
The interphase stage is the longest phase in the cell cycle, encompassing growth, development, and prep for cell division. Because of its length, it's most likely to be observed when viewing cells.
Most cells that we view under a microscope will be in the interphase stage because this is the longest phase of the cell cycle. During interphase, the cell grows, develops, and prepares for division. It includes three stages: G1, S (where DNA replication occurs), and G2. These processes take up around 90% of a cell's life cycle. Therefore, when observing a population of cells, it's most likely you'll see a cell in one of the interphase stages, simply due to the likelihood based on the duration of these stages relative to the cycle as a whole.
