List and describe three factors that affect how quickly enzymes can work to catalyze reactions
Lilit [14]

Answer:

The correct answer is - temperature, pH, substrate concentration.

Explanation:

Various factors affect the rate of enzymatic reaction such as pH, temperature, substrate concentration, availability of activators or inhibitors in the reactions, and enzyme concentration.

Temperature: Temperature affects the rate of the enzyme-catalyzed reactions. Like most of the reactions with an increase in temperature rate of enzymatic reaction also rises up to a maximum level and then declines if the temperature continues to increase as enzyme denatures after a particular temperature.

pH: Similar to the temperature pH also increases the rate of reaction up to a maximum level and then declines the rate as every enzyme acts only at an optimum pH range.

Substrate concentration: If the substrate concentration is increased gradually while the concentration enzyme remains constant, the rate of reaction will increase until it reaches a maximum.

Children are spending less time outdoors in nature because of which reason(s)
Mrrafil [7]
The two biggest reasons for children spending less time outside are the development of technology and the safety issues. The development of technology brought in our homes countless forms of having fun which is very important to children. The mobile phones, PC's, laptop's, tablets, Sony Play Station, as well as lots of technologically improved toys, made the children stay at home since they have the fun indoors, and not be interested in going outside and in nature. Also the safety issues in lots of parts in the world made the parents to restrict the children to the indoors environment.

Over time, a plant pollinated by a hummingbird has developed very long, tube-like flowers. Why might the flower have adapted in
erik [133]
The flower would have adapted to allow the hummingbird to better pollinate it. I believe this to be true because it follows the process of adaptation.

What are some similarities and differences between landslides and creeps? Thank you!
dimulka [17.4K]

Answer:

A mass movement can either be slow or rapid. The slow downward movement of materials in a slope is called creep. This happens when the soil loosens up because of water and burrowing animals. In contrast to this, the rapid movement of large materials in a slope is called landslide.
