Answers

Answer 1

Hibernation is an adaptation that helps alpine animals to survive the cold winter. Hibernation helps to store energy.

Hibernation is an adaptation that helps to store energy by decreasing the metabolic rate.

This adaptation (hibernation) is observed in animals living in extremely cold conditions (e.g., alpine animals).

The hibernation adaptative strategy is characterized by an excessively low temperature in the body, slow breath rate, slow beats (heart rate), and low metabolic rate.

Nature vs. Nurture both influence the observed traits of an organism.

The controversy between nature and nurture have been an ongoing discourse for many years. It is believed that the traits of an organism are dependent on genes inherited from the parents. Another school of thought believes that environment alone has the sole influence over the traits of an organism.

However, most scientists today are of the opinion that the influence of nature and nurture are intertwined and they both work together to influence the traits exhibited by any organism.

2) Why is the mixture of milk and bacteria incubated at 45 °C?

3) what causes the milk to thicken?

4) why does fermentation eventually stop?

5) Explain how making yogurt is a way of preserving the nutrients from milk.

Answers

It should be noted that milk is pasteurized at the start of the process in order to kill bacteria.

The mixture of milk and bacteria is incubated at 45 °C to kill the bacteria.

The drop in pH causes milk to thicken. Fermentation is stopped when the alcohol concentration rises to a point where it kills the yeast cells.

Lastly, making yogurt is a way of preserving the nutrients from milk as the bacteria ferment the milk thereby turning the lactose sugars to lactic acids.
