Answer:
e. separate chromosomes during cell division.
Explanation:
The formation of the spindle apparatus starts in the prophase stage of mitosis. The spindle is made of microtubules. The kinetochore microtubules become attached to kinetochores of the centromeres of chromosomes. This attachment helps in the alignment of the chromosome at the cell's equator during metaphase. Depolymerization of kinetochore microtubules shorten them and thereby assist in the separation of sister chromatids to opposite poles during anaphase.
A cell that is unable to polymerize microtubules will not be able to form a spindle apparatus during mitosis. Chromosomes would not be aligned at the equator in metaphase and there will not be the separation of sister chromatids to the opposite poles of the cell during anaphase.
The given question is missing the chart or the details of blocks, each week. However, the details of the blocks are as follows:
1week = 2blocks
2weeks = 3blocks
3weeks = 5blocks
4weeks = 4 blocks
5weeks = 5blocks
Oweeks = 5blocks
7 weeks = 3blocks
Answer:
The correct answer is - 13.5 cm.
Explanation:
According to the details of the blocks, the number of blocks each week as follows:
1week = 2blocks
2weeks = 3blocks
3weeks = 5blocks
4weeks = 4 blocks
5weeks = 5blocks
Oweeks = 5blocks
7 weeks = 3blocks
Adding total blocks would be :
2 +3 + 5 + 4 + 5 +5 + 3 = 27 blocks
Each block equals 5 mm of growth.
Then, 27 x 5 = 135 mm
135mm = 13.5 cm
Thus, the correct answer is : 13.5 cm
Chloroplasts are only found in plant cells because it is the organelle that makes photosynthesis possible and it makes food for the plant cells as in it makes its own food and animal cells dont need them because animals eat other animals for that food
