Answer:
Mitosis is used to produce daughter cells that are genetically identical to the parent cells.
Explanation:
The cell copies its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
<span>D. 9 </span>
<span>Notice that diploid cells which 18 are the complete number of chromosome pair of the organism. This usually happens under cell divison –mitosis which process of replicating oneself to produce another like cell. Meiosis occurs in gametes, sex cells. Their respectively called spermatogenesis (sperm cells) and oogenesis (egg cells). These cell division –meiosis produces haploid cells, in which in words “half” from the complete cell chromosome number, hence, these </span>haploid cells<span> only produce half number or one set of chromosome (9) instead of the complete pair which in this case, 18.<span>

Vestigial structures are taken as an example of evolution because they give us an indication of structures that, due to the adaptation to the environment, disappeared.
At the end of the vertebral column, we have the coccyx as an example of this. Its believed that it could have formed a tail and currently, is only a small bone without any specific function, even some individuals are born without it.
The reactivity of an atom is due to the number and arrangement of Electrons (b) in the outer energy level.
Electrons "bond" they're the ones that react to create other elements.
Examples: Salt (NaCl) Carbon Dioxide (CO2)
And so on, and so forth. Thus, your answer....B.
Answer:
The most common tertiary structures of these proteins are transmembrane helix bundle and beta barrel. The portion of the membrane proteins that are attached to the lipid bilayer consist mostly of hydrophobic amino acids.
