A green roof produces heat loss
Answer:
Explanation:
First, let's identify the tools needed.
Since the biology class is studying the temperature, they will likely need a <u>thermometer</u>. Also, they are gathering information about the growth of the plants. This could use a <u>balance </u>of a meterstick.
Next, recall the difference between quantitative and qualitative data.
- <u>Quantitative</u>: Measurable and numerical results found using scientific instruments/devices
- <u>Qualitative</u>: Data found using the senses, such as descriptions and diagrams.
Since the class is measuring temperature and growth using tools, it must be quantitative data.
We can eliminate choices A and B, because they claim the class will gather qualitative data. Then, we can eliminate choice D, because a beaker and timer won't help with temperature and growth. That leaves choice C as the correct answer.
I dont know if have this but... i have this questio and it is c
Answer:
B
Explanation:
Cytokinesis, which is the division of a cell's cytoplasmic content, is the final step of cell division. After which the genetic material of a cell duplicates, they move towards opposite directions in the cell. The cytoplasm of the original cell halves itself equally for the two resulting cells. Though both animal cells and plant cells go through cytokinesis, they undergo it differently due to the presence of cell wall in addition to the cell membrane in plant cells.
In plant cells, cytokinesis mainly involves the formation of a CELL PLATE at the equator of the parent cell that will soon divide into two. The cell plate, which is the future doubled cell wall that will become separated into two cells, divides the cytoplasm.
In animal cells, cytokinesis occurs in a more complex manner. A fissure called CLEAVAGE FURROW develops by the formation and contraction of the CONTRACTILE RING, which is present beneath the parental's cell membrane and made up of actin filaments. The created furrow grows deeper (as the actin ring contracts) between the two resulting cells until they meet the membrane and pinch off (inwardly), separating from one another. Hence, resulting in two separate daughter cells.
