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
Answer:
B. similar to the cells just treated with the dye - 0% dead
Explanation:
According to this question, an experiment was set up in which kidney cells were treated with a chemical for different amounts of time. Hence, the independent/manipulable variable is the CHEMICAL.
Based on the observation of the group of cells, a cell that has been damaged by the chemical will appear pink when treated with dye while a cell treated with only due but no chemical will not appear pink.
A NEGATIVE CONTROL is the group in an experiment that is not treated with the independent variable i.e. doesn't receive experimental treatment. Since the independent variable in this experiment is the CHEMICAL, the negative control will be the group that doesn't receive the chemical treatment. Hence, the negative control is similar to the cells just treated with the dye - 0% dead
Answer: The layers of the cell membrane is made of lipid
Explanation:
The cell membrane is made of a double-lipid layer, so it permits large steroid molecules like Estron or cholesterol since they are non-polar and lipid-friendly, whereas it does not permit the hormone adrenaline because it is a polar and charged molecule and non-lipid friendly.
