Answer:
The correct option is: 4. Heat at 62.8 degrees C for 30 minutes
Explanation:
Pasteurization is the process or technique of heating packaged as well as the unpackaged liquid food, to remove pathogens and extend the shelf life. In this process,<u> the food is usually heated at temperatures below 100 °C.</u>
Originally, this process involved heating the food at 72.2 °C for 15 seconds and <u>62.8 °C (145 °F) for 30 minutes, for batch pasteurization.</u>

Changes in the dna are called mutations. They can occur spontaneously. Mutations can only be passed down in gametes--sperm and egg cells. with Darwins theory at mind a mutation needs to pass the test of natural selection to remain in the gene pool. So purposly making mutation or altercations may end in diseases/illnesses or in some cases death because they body can not take it.....hope this helps if it doesnt im sorry!
Answer:
Although more offsprings are produced by the process of external fertilization but the process of internal fertilization is more efficient as compared to external fertilization. This is because, in external fertilization, it is more difficult for the sperm to find the egg and fertilize it. Even after fertilization, it might be that the zygote gets eaten up by a predator. There are none such risks in internal fertilization. The zygote is protected during the internal fertilization which makes this process more efficient.
The answer is descent with modification.
Descent with modification practically means that a species have changed appearance wise over long periods of time to adapt to their environments better.
