C. Sex cells
Explanation:
The process shown in the figures is Mitosis, which is the division of cells that end in 2 identical daughter cells. Sex cells, however, do not go through mitosis as their offspring are genetically different; they go through a process called meiosis. The other cells listed are all somatic and therefore go through mitosis, so C must be correct.

How can change over time account for the diversity of beetles?
Answer:
Beetle diversity thus appears to have resulted from multiple factors, including low extinction rates over a long evolutionary history, codiversification with angiosperms, and adaptive radiations of specialized herbivorous beetles following convergent horizontal transfers of microbial genes encoding PCWDEs.

What is an exothermic reaction?When a chemical reaction takes place, energy is transferred to or from the surrounding in the universe. When the energy is transferred to the surrounding, there is a loss of energy, this reaction is called an exothermic reaction, and the temperature of the surrounding increases during this reaction.
The process of dissolving a substance is exothermic when more energy is released when water molecules bond to the solute particles in the solution than is used to break the solute particles apart. Because, more energy is released than is used in this process, the molecules which are present in the solution move faster, and thus results in an overall increase in temperature.
Therefore, the correct option is C.

What might happen if the number of chromosomes within the cells did not change but new daughter cells were still made? (meiosis)
Answer:
No fertilization occurs.
Explanation:
No zygote is formed if the the number of chromosomes within the cells did not change or remain the same i.e. diploid because for the production of zygote, half number of chromosomes are required in both male and female sex cells or gametes. If the chromosomes are half in both gametes so they fuse with each other forming zygote having diploid cell so we can conclude that for the happening of fertilization process, half number of chromosomes in gametes is necessary if not, no fertilization occurs.
