Answer/Explanation:
Recall:
Volume of a sphere = ⁴/3πr³
Surface Area = 4πr²
✔️For radius (r) = 1 mm:
Volume = ⁴/3 × π × 1³ = 4.19 mm³
Surface Area = 4 × π × 1² = 12.57 mm²
Ratio of volume to surface area = 4.19 : 12.57 = 1:3
✔️For radius (r) = 3 mm:
Volume = ⁴/3 × π × 3³ = 113.1 mm³
Surface Area = 4 × π × 3² = 113.1 mm²
Ratio of volume to surface area = 113.1 : 113.1 = 1:1
Answer:
The nuclei of the skin cells produced by mitosis will have identical genetic material as that of the parent cell.
It is because mitosis is a type of cell division in which a parent cell divides into two daughter cells, each having equal and identical chromosomes as that of the parent cell.
In addition, events like crossing over do not take place due to which no genetic variation is developed in the daughter cells.
The process of mitosis is mainly involved in the repair and growth of the body.
The three liquids will form three layers, the bottom layer is more dense and the top layer is less dense
Non point source pollution is a greater threat than point source pollution because non point source pollution disrupts the water cycle.
Water evaporates from the ocean and land surfaces, is held temporarily as vapour in the atmosphere, and falls back to Earth's surface as precipitation. ... Water that infiltrates Earth's surface becomes groundwater, slowly seeping downward into extensive layers of porous soil and rock called aquifers.
