Answer:
D. Sami had low birth weight as a lamb but quickly grew into a large sheep.
Explanation:
The Sami lamb is an example of culled because it has the characteristics of quick growth. Culling is the process of separating organisms from a group of same type of organisms due to presence of desired or undesired characteristics. Sami sheep has a unique characteristic of having less weight at time of birth but having quick growth features that make to gain more weight and become large sheep so this sheep is removed from the population for its good traits.
Answer:
Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). Being warm-blooded creatures, humans can increase or decrease temperature internally to keep it at a desirable level.

Answer:
The activities of enzyme depends on the <u>temperature</u>, <u>ionic</u> conditions and the <u>pH</u> of the surroundings.
Explanation:
<u>Effect of temperature on enzymes</u>
Enzymes show low level of functioning at lower temperatures. As the temperature is raised, the activity of the enzyme increases. The enzyme activity becomes optimal at a specific temperature. Beyond this temperature, the enzyme's activity rate starts to decline until it gets denatured.
<u>Effect of ionic conditions on enzymes</u>
Studies show that certain enzymes require some cations for functioning. But an increased amount of cations or anions can inhibit the functioning of the enzymes.
<u>Effect of pH on enzymes</u>
Each enzyme has an optimum pH at which it works best. If the pH is increased or lowered than this optimum pH, then the activity of the enzyme starts declining until it gets denatured. Most enzymes work best at pH 7.0
