Answer:
The endoplasmic reticulum (ER) and nuclear membrane of modern eukaryotes are continuous.
Explanation:
The evidence of the hypothesis that nuclear envelope of eukaryotes originates from the infoldings of the plasma membrane.
The nuclear membrane and the endoplasmic reticulum of the eukaryotic cells are continues in nature. They are made of protein which are infolded because there is not much space inside the cell so the things inside are either condensed or infolded.
The two kinds of basic cell division include mitosis and meiosis.
Mitosis is where a parent cell divides and produces 2 genetically indentical daughters cells. So this means that when the cell division is complete, the number and even the sequence of chromosomes is exactly same as the original parent cell.
And in meiosis, also called reduction division, is where the parent cell divides and produces 4 genetically different daughter cells, which has only half of the number of chromosomes than that of the original parent cell. This process has to go through 2 times of divisions.
Mitosis is usually seen in most somatic cells, it is very important to activities such as growth, repair etc. Meanwhile, meiosis is seen in gametes, and its important for sexual reproduction.

Answer:
C
Explanation:
The student would need to hold all other variables (temperature and seed type) constant in order for this experiment to be valid.
Work done is force times distance where in this case force is 300N and distance is 0.60m
w=300*0.6=180Joules.
therefore the work done is 180 joules.
