Q. What is the curved surface area of the cylinder if radius is 7 cm and height is 10 cm?
Hence, the curved surface area of the cylinder is 220 cm2 and the total surface area of the cylinder is 377.14 cm2.
Q. What will be the total surface area of a cylinder whose base radius is 7 cm and height is 13 cm 1 point?
Answer :- Curved surface area of cylinder = 440 cm². Total surface area of cylinder = 748 cm². Volume of cylinder = 1540 cm³.
Q. What is the height of a cylinder whose radius is 7cm and the total surface area is 968 sq cm *?
15 cm is the height of the cylinder if the radius is 7 cm and total surface area is 968 .
Q. What is a large surface area to volume ratio?
SA:V ratio When an object/cell is very small, it has a large surface area to volume ratio, while a large object/ cell has a small surface area to volume ratio. When a cell grows, its volume increases at a greater rate than its surface area, therefore it’s SA: V ratio decreases.
Q. What is the surface area to volume ratio of a 6 cm cube?
So, for a cube that’s one centimeter on a side, the surface area is 6cm2 (1cm x 1cm x 6), the volume is 1 cm3 (1cm x 1cm x 1cm), and. the surface area to volume ratio is 6 units of surface: 1 unit of volume.
Q. Why is the surface area to volume ratio important?
Surface area to volume ratio is vital in so many biological processes. Therefore cells are limited in their size because if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. …
Q. What happens to the ratio of surface area to volume as the cell size increases without the cell changing shape?
For cubes smaller than this, surface area is greater relative to volume than it is in larger cubes (where volume is greater relative to surface area). clearly illustrates that as the size of an object increases (without changing shape), this ratio decreases.
Q. How can cells increase their surface area?
Explanation: Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration. These foldings increase the surface area.
Q. What must a cell do before it divides?
Before a cell divides, the strands of DNA in the nucleus must be copied, checked for errors and then packaged into neat finger-like structures. The cell division stages encompass a complicated process that involves many changes inside the cell.
Q. What are the two phases of cell division?
In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.
Q. What is the correct order of the cell cycle?
The correct order of the cell cycle is G1, S, G2, M and possible exit into G0.
Q. What are the phases of cell division?
Today, mitosis is understood to involve five phases, based on the physical state of the chromosomes and spindle. These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
Q. What are the five phases of the cell cycle?
Mitosis, although a continuous process, is conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase and telophase.
Q. What is uncoiled stringy DNA called?
chromatin
Q. Where does mitosis occur in the body?
The cells of the skin and bone marrow are sites of active mitosis replacing skin cells and red blood cells that only have a limited life. Repair. When an area of tissue is damaged internally or externally, mitosis is used to repair the damage.
