Why would there be a relationship between photosynthesis and temperature<br><br> Help me
Mumz [18]

Answer:

Enzyme-controlled chemical reactions combining carbon dioxide and glucose water. The photosynthetic rate is affected by the temperature much like any other enzyme-controlled reaction.

Explanation:

At low temperatures, the number of molecular collisions between enzymes and substrates limits the photosynthetic rate. Enzymes are denatured at high temperatures.

Enzymes are protein molecules used in biological reactions by living organisms. The proteins are folded in a very specific form, which enables them to effectively bind to the molecules of interest. The enzymes used for photosynthesis perform less efficiently at a low temperature between 32 and 50 degrees Fahrenheit 0, 10, and 10 degrees Celsius, which lowers the photosynthesis rate.This will lead to lower glucose synthesis and slow growth. In the case of plants in a greenhouse, this is prevented by installing a greenhouse heater and thermostat.

What activation energy was used to start the chemical reaction in the burning marshmallow?
Sonja [21]

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, let's understand some terms

Activation energy is the minimum amount of energy required for a reaction to proceed. Under normal condition, when the activation energy is high, it takes longer for the reaction to proceed than when it is low.

The burning of marshmallow is an exothermic reaction as it involves the transfer of heat energy into the environment.

Describe how humans’ way of life has changed. Begin with hunter-gatherers and end with life after the Industrial Revolution.
iragen [17]

Answer:

Ever since the existence of life of humans on Earth, the humans have been making progress to understand themselves and the mother nature.

In the start, the humans were hunter- gatherers. Hunter- gatherers can be described as humans which use wild life plants and animals for food. The humans used to live in jungles and eat the wild- life plants and animals. They used leaves from the trees to cover their bodies. Heat was produced by rubbing the rocks.

After this time, the humans learned the techniques of cultivating plants for food. They started cultivating crops and depend on them for living. During this time, humans learned the art of farming and agriculture. But they couldn't understand the effects of various pathogens infecting the crops and humans at that time.

After this time, humans learned the art of preserving foods in different forms like pickles etc. They also learned that certain types of plants could be used to treat wounds and other diseases.

With the passage of time, people learned to make and use machinery for making their tasks easier. The usage of machinery progressed rapidly and the industrial revolution began. People became more diverted to this sector rather than farming. They started to move towards the cities to find better jobs in industries.

Life after industrial revolution was much easier as humans had made a lot of equipments which aid them to have a better life style. Science has been developing since that time day by day.

A population of large predators in an ecosystem has been trapped and removed from the area. How would this event most likely cha
Kay [80]
When a top predator is removed from an ecosystem, a series knock-on effects are felt throughout all the levels in a food web, as each level is regulated by the one above it. This is known as a trophic cascade. The results of these trophic cascades can lead to an ecosystem being completely transformed. The impacts trickle down through each level, upsetting the ecological balance by altering numbers of different animal species, until the effects are finally felt by the vegetation.
