Answers

Answer 1
Answer:

Answer:

The statement D 'they are assisted by vitamins and minerals' is incorrect.

Explanation:

Enzymes are biological catalysts which speed up a reaction. Their working mechanism is usually referred to as lock and key mechanisms as they make a lock and key type model while functioning. Each enzyme is specific for a specific kind of substrate. All enzymes are proteins. Enzymes itself are not degraded or get used up in a reaction. They might change from one form to another. But they are not assisted by vitamins or minerals, hence that statement is incorrect.

Answers

Answer is labyrinthodont

About 110 million years ago, labyrinthodonts ( maze-toothed), a group of extinct amphibians. They were evolved from lobed-finned fish in the Devonian period. They were dominant animals in the rift valley was present at that time between Antarctica and Australia.

Explain differences between exponential growth and logistic growth.

Answers

Answer:

The biggest difference, however, is that the line in the logistic growth graph changes direction and begins to level off as it nears the carrying capacity. That means that the main difference between exponential and logistic growth is that logistic growth takes into account carrying capacity.

Answer: So the difference between exponential growth and logistic growth is that Exponential growth model is one that exists when the the rate of growth is proportional to the existing amount. For this, a population need ideal conditions: bacteria in a petri dish, radioactive decay or compound interest in a saving amount. The logistics is a different kind of behavior which is more realistic to population not in ideal conditions: the rate of growth is proportional to the amount but there is also a damping factor due to competition and limited resources. This model works that at first the rate of growth getting faster then it slows down since there are too many individual competing on limited space. When this population reaches its equilibrium state, the rate of growth is zero and if there will be no interruptions, the size of the population will stay constant.

How much faster does sound travel in the ocean than in the rain forest?

Answers

Hi there,
Speed of sound in water is approximately 1500 meters per second (the exact speed depends on the depth of water and its density) and the speed of sound in air is approximately 340 meters per second. So sound is almost 4.4 times faster in water than in air. I hope this helped :)

Describe the direction of the flow of thermal energy if a bowl of ice cream sits on the counter of the kitchen.

Answers

Answer:

The bowl of ice cream contains ice cream with temperature below freezing point. A hot body contains more thermal energy than a cold body. Thermal energy only flows from a hot body to a cold body, and not the reverse.

The bowl of ice cream contain less thermal energy than it sorrounding envoirment (air and the kitchen counter), this creates a temperature gradient that forces thermal energy from the sorrounding envoirment into the bowl of ice cream because, according to thermodynamics, all bodies always tend to be in thermal equilibrium with its sorrounding. The thermal energy flows into the bowl of ice cream until it has the same thermal energy with its sorrounding; bringing the thermal gradient between them to zero.
