Answer:
The answer is : recombinant DNA combines genes from two different organisms
Transformation is the genetic alteration of a cell resulting from the direct uptake of incorporation of exogenous genetic material from its surrounding through the cell membrane.
Answer: Water
Explanation:
Though Cell membranes are selectively permeable to solute, cell membranes are permeable to water.
An osmotic pressure is exerted on cells when the osmolarity of their external environmental is more greater than their internal environmental.
When an osmotic pressure is exerted on cells for the cells to survive, water molecules move from the region of lower concentration to a region of higher concentration until there’s a balance in osmolarity.
Cell membranes are freely permeable to water.
Answer is water.
If a cell has 18 chromosomes the daughter cells would have 18 chromosomes after mitosis.
c. 18
<u>Explanation:</u>
Mitosis is the DNA replication process which maintains the number of chromosomes in daughter cells equal to number of chromosomes in parent cell. In the process the parent cell divides into two daughter cells having the same chromosome number as that of parent cell.
Meiosis is a process different from that of mitosis where each parent cell divides into four daughter cells having half the number of chromosomes present in the parent cell.
Since sex cells have to be haploid in organisms like human beings, it is the process of meiosis that takes place in reproductive cells.
