Answer:
During meiosis 1, the parent cell with double the normal amount of chromosomes, splits into two diploid cells (have enough chromosomes to survive). During meiosis 2, the two diploid cells each split into two haploid cells (have half the amount of chromosomes to survive). Meiosis ends with four haploid cells.
Answer:
There is no change, the lac l gene is constitutively expressed, regardless of the presence of lactose.
Explanation:
Lacl gene codes for the lac repressor hence is always expressed to produce lac repressors which may or may not be bounded dependent on the presence of lactose. Lacl gene expression is not regulated, thus is constitutively expressed.
The pressure would increase. This can be explained by the ideal gas law where for an ideal gas its pressure, volume and temperature is a function of each other ans is expressed by an equation: PV = nRT. We first need to assume that this gas given is ideal. When the temperature and the number of moles is set to a constant value while the volume decreases, we can see that from the equation pressure and volume are indirectly proportional to each other, therefore as the volume decreases, the pressure inside increases.
