Meiosis is a kind of cell division. It will lead to 4 daughter cells which each has only half of their chromosomes comparing to the parent. The end product has less chromosomes than the original that's why it's called reduction division.
Meiosis is important because the products are usually seen in gametes, which is sperms and eggs. If they get fertilized, they will form a zygote, and this is reproduction. Meiosis makes sure that the zygote has the right number of chromosomes, like half and half equals the correct amount chromosomes the organism should have. This also leads to diversity which is very important and a must in sexual reproduction.

Answer:
a) the covalent bond between the last phosphate and the middle phosphate
Explanation:
The ADP is composed by a molecule of Adenine, Ribose and two Phosphate groups. The addition of a paper weight in the spring represents the last phosphate added in a ADP, resulting in a ATP. The last phosphate connected with Ribose by a covalent bond, represented by the round paper weight connected to a spring, can be easily detached in order to provide energy to the cell by a process called dephosphorylation. The spring compressed represents the energy of the bond. In the model the compressed spring is represents the potential energy, but in the bond the energy is chemical, which will lead into a electron transference reaction.
The lac operon contains an operator, promoter, and structural genes that are transcribed together and are under the control of the catabolite activator protein (CAP) or repressor.The lac operon encodes for the genes needed to utilize lactose as an energy source. Answer is C
