I temperature will continually rise until it melts assuming you do not stop applying heat to the ice. It doesn’t really matter at what temp below freezing you start as long as you go above freezing the ice will melt.

What happens to an enzyme if the temperature varies too far from the enzyme's optimum (or best) temperature?

Fantom [35]

If the temperature is too low, enzyme molecules don’t have enough kinetic energy to collide and combine with other substrate molecules. So the enzyme activity/ reaction rate will be very low. The rate will rise again once the temperature increases to its optimum temperature.

But if the temperature is too high, enzyme will be denatured, which means the shape of the active site of the enzyme is changed. It can no long combine with other substrate molecules. The rate will drop significantly. Yet, lowering the temperature won’t help because denaturation is permanent and irreversible.

What is the differences between nuclear DNA and mitochondrial DNA?

oee [108]

Answer:

Believe it or not, mitochondria are their own organisms!

That’s right, they are single celled living beings that hitch a ride inside our cells for security, and in return they make our energy systems run much better than they would. This arrangement started a very long time ago, before we split from our last ancestor with plants, and long before we became multicellular. Other than this arrangement, our DNA has nothing to do with the DNA of the mitochondria (other than synergistic evolution making us more compatible with one another).

For this reason, it is easy to see how mitochondrial DNA differs from nuclear DNA.

First major difference is that we are in different kingdoms and even different super kingdoms to mitochondria (I know there are only meant to be 5 kingdoms but in biology people often use a system based off genetic differences, leading to a huge array of kingdoms that are often really distantly related). So our DNA and mitochondrial DNA share very few similarities. We both replicate our DNA using the same method and have the same base pairs, but the DNA itself says different things.

Another difference is that mitochondria generations are very fast compared to humans’, so their DNA undergoes genetic drift at a much faster rate, and changes more over time. Therefore it is much easier to locate recent changes in populations, for example the migrations out of Africa in the last 200,000 years, or the ethnic backgrounds of different African races, using mitochondrial DNA. In contrast nuclear DNA has fewer fine mutations that can be used as a map for recent events (in the last million years, say).

Mitochondria are passed down from mother to child in animals, so you will always have your mother’s mitochondrial DNA. This is why there is a mitochondrial Eve- this is the last female that is an ancestor of everyone on the planet, and therefore every human possesses direct ancestors of her mitochondria (and her nuclear DNA). In contrast we receive a 50/50 split of nuclear DNA from father and mother.

I hope this helps!

<h2>Discretionary calories</h2>

Explanation:

Discretionary calories are overabundance calories to appreciate once your necessary supplement needs are met. They can be utilized toward higher-fat types of nourishments like milk, cheddar and meat, and high-fat and sugary fixings, for example, margarine, sauce, sugar, and syrup. Discretionary calories can likewise tally toward pop, treats, and liquor
On the off chance that none of these nourishments sound alluring, they can even be utilized for extra servings of your preferred solid food sources
