Answer:
Anaphase II.
Explanation:
Cell division may be defied as the phenomena by which the cell multiply and increases its number under the influence of cell cycle checkpoints. Two main type of cell division are meiosis and mitosis.
The meiosis result in the formation of four haploid cells from the single parent diploid cell. The Anaphase II of meiosis leads to the disjoin of the sister chromatids and the separation of chromatids. This is similar to the anaphase of mitosis.
Thus, the correct answer is anaphase II.
Answer:
A. pH
Explanation:
Denaturation of proteins is a protein whereby the protein molecule loses its primary structure and ultimately its physical functioning as a result of factors including pH, temperature or concentration of chemicals. Based on this definition, it is visible that denaturation of proteins can be caused by these three factors: pH, chemical and temperature.
However, in this case of PEPSIN enzyme, which is a proteinous molecule produced in the stomach of humans and functions in breaking down proteins, its denaturation occurs as it moves along the digestive tract to the intestines. This is as a result of the changes in pH in the digestive tract.
The pH of the stomach where pepsin is produced is acidic i.e. <3.0. However, as one moves towards the intestine, the pH increases, which is unfavorable or considered harsh for the pepsin enzyme. Hence, it gets denatured.
Answer: Clearly his SYMPATHETIC nervous system has been activated.
Explanation:
The effects of the sympathetic nervous system dominate in times of EMERGENCY or STRESS. And its effects include:
- dilation of pupils to help Gabe see sharply as he investigate
- inhibition of saliva secretion as his mouth turns dry
- acceleration of heartbeat due to fear
- stimulation of sweat glands to produce sweat.
All these show clearly that Gabe's SYMPATHETIC nervous system has been activated.
