What process describes the release of materials across the cell membrane? a Phagocytosis b Exocytosis c Active transport d Pinocytosis 16. What part of cell regulates the passage of substances into and out of the cell? a Golgi apparatus b Smooth endoplasmic reticulum c Nucleus d Cell membrane 17. How many chromosomes would be present in the gametes of a diploid organism with chromosome number of 46? a 46 b 69 c 23 d 92
Explanation / Answer
12. Ans-a TGGACT
In DNA strand, the nitrogen bases which complementary to each other are A-T and C-G. Therefore, the other strand is TGGACT.
13. Ans- c. Gamete
During meiosis division, each homologous chromosome produced new "gamete".
14. Ans- b Golgi apparatus
Golgi apparatus act as a packing and distribution center.
Mitochondrion is called powerhouse of cell
Nucleus act as a carrier of genetic information
Ribosome involved in protein synthesis
15. Ans- b. Exocytosis
Exocytosis – It is a process of release of large particles across the cell membrane.
Phagocytosis is the process of engulfing of bacteria and other microbes.
Active transport is a movement of material against the concentration gradient
Pinocytosis is the process of uptake of fluid and any small molecules.
