Experimental errors can be of two kinds: human error and analytical error. Analytical error can be corrected easily. You just have to use instruments that are of high precision. For example, instead of using the platform balance, use the analytical balance which displays 4 decimal places to be highly accurate. For the human error, this is subjective. The only way to correct human error is to be more meticulous on your data measurements.
Answer:
animal cell
Explanation:
Cytokinesis -
It refers to the process of cell division, which takes place during mitosis, is known as cytokinesis.
The process of cytokinesis is different for animal cell and plant cell.
- Where, in case of plant cell, a separation, known as cell plate is formed along the center of the parent cell, which is responsible for the separation of the cells.
- Whereas, in case of animal cell, the plasma membrane contracts itself along the center, until the two daughter cells are separated from each other.
Hence, from the given information of the question,
The correct answer is animal cell.
Answer:
The mole is the SI unit for amount of a substance.
Explanation:
Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.
No one can do that by him or her self
Answer:
Initial temperature of the gas cylinder was 167.7K
Explanation:
Based on Gay-Lussac's law, the pressure of a gas under constant volume is directly proportional to its absolute temperature. The equation is:
P1*T2 = P2*T1
<em>Where P is pressure and T absolute temperature of 1, initial state and 2, final state of the gas.</em>
<em />
Replacing:
P1 = 1.25atm
T2 = 354.2K
P2 = 2.64atm
T1 = ?
1.25atm*354.2K = 2.64atm*T1
167.7K = T1
<h3>Initial temperature of the gas cylinder was 167.7K</h3>
