Answer:

1.b:Enzymes increase the rate of reaction.

2.b:lowering the energy of activation of a reaction.

Explanation:

1.Enzyme : Enzymes are biological catalyst .It is defined as proteins binds to  a molecule and increase the rate of reaction.It does not change in the reaction only it increases the rate of reaction.

Enzyme does not decrease the free energy change of a reaction.Enzymes do not change in the concentration of substrate and do not prevent the changes in substrate concentration.It only increase the rate of reaction .

Therefore, option b is true.

b:Enzymes increase the rate of reaction.

2.Activation energy:It is defined that minimum energy which is required for molecules to start  the reaction .

When an enzyme catalyze a reaction then the activation energy of energy of molecules decreases and speed up the reaction.

Hence, option b is true.

Answer :b:lowering the energy of activation of a reaction.

The seeds of leguminous plants are a source of proteins. Nitrogen - fixing bacteria live in the roots of such plants. Do you thi
enyata [817]
Yes, Only bacteria can convert molecular nitrogen, into a form which can be utilized by other living beings such as plants. The nitrogen fixed by the bacteria, by this process, become available to the plants, which uptakes it, for their own growth, and is also accumulated in their seeds. Further, leguminous plants have nitrogen-fixing bacteria associated with them in synergy. They provide the plant with additional nitrogen, and in exchange obtain nutrients from the plant, for their growth and division.

Answer:

Triassic Period (252 to 201 million years ago)

All continents during the Triassic Period were part of a single land mass called Pangaea. This meant that differences between animals or plants found in different areas were minor.

The climate was relatively hot and dry, and much of the land was covered with large deserts. Unlike today, there were no polar ice caps.

It was in this environment that the reptiles known as dinosaurs first evolved. Reptiles tend to flourish in hot climates because their skin is less porous than, for example, mammal skin, so it loses less water in the heat. Reptile kidneys are also better at conserving water.
