Answer:
E2F transcription factors
Explanation:
The E2F transcription factors (TFs) encode intracellular factors associated with the control of the cell cycle. E2F are TFs that bind to promoter consensus sequences in order to activate transcription. These TFs control the expression of target genes involved in cell proliferation including, among others, genes for DNA replication and mitotic activation. Moreover, the E2F proteins also may act as a link between cell fate and the cell cycle. The retinoblastoma (Rb) is a protein that modulates the activity of the E2F family of TFs, and it has been shown that the Rb/E2F pathway is a key molecular mechanism associated with cell proliferation.
Since the question is incomplete, the answer will include the generalize ways that can be used to analyze evolutionary relatedness among gibbons, monkeys, and humans.
Answer:
The evolutionary relationship is important to understand the evolution of the organisms. The common ancestors and closely related species of the organisms can be known by study the evolutionary relationship of the organism.
The DNA sequence and the amino acid sequence of gibbons, monkeys, and humans are quite similar with each other. The gibbons and humans have more then 99% DNA sequence similarity. The physical characteristics, cranial capacity and anatomical characteristics of the gibbons, monkeys, and humans are more or less similar with each other.
Answer:
We should not touch electrical appliances with wet hands because our body is a good conductor of electricity and since we may get electric shocks. ... Also one should avoid getting wet while touching electrical appliances because water is also a conductor not pure one though
Explanation:
Answer: Backdating the time required for food found in the stomach of the deceased to digest. Since digestion can't continue after death.
Explanation: The time taken for food to get digested can be employed to depicts time of death. This process involves understanding the period of time that usually takes the food found in the gastric of the deceased to calculate the time of death.
Different foods has varying time of digestion, so therefore, the gastric content is a good indicator to determine time of death by the doctor who is carrying out autopsy, since digestion does not continue after death.
However, it is established by scientist that food takes up to 4-6hours in the stomach depending on the size and type of food. Hence, if the status of the food found in the deceased stomach is noted accordingly and the time taken requires for digestion is also noted، the doctor can deduce the time of death accordingly from this two points.
