The correct answer is - magma intrusions.
The metamorphic rocks are rocks that basically have been either igneous or sedimentary, but have changed under certain circumstances. The initial igneous or sedimentary rocks, because of the geologic activities, often end up deep into the ground. As they get deep into the ground, they are exposed to higher temperatures and higher pressures, which over time change their structure, thus the creation of the metamorphic rocks. Also, the intrusion from the molten rocks known as magma, influence the creation and the type of the metamorphic rocks. This influence can be expected at places that are close to the plate boundaries, and where there's active volcanic activity in the region.
Plants make their food using a process called, photosynthesis. Some plants reproduce by making seeds or spores. Another one is adaptation, which helps the plants store water and to reduce water loss.
They have vascular tissue and use pollen and seeds to reproduce. However, some plants have a complex life cycle that includes the sporophyte and gametophyte stages.
Here are the answers:
1. WHAT YOU WILL BE LOOKING FOR AS EVIDENCE OF REACTION IN THIS EXPERIMET IS FORMATION OF OXYGEN BUBBLES.
This is because, the catalase enzyme on which this activity is based is an enzyme that speeds up the rate of decomposition of hydrogen peroxide in the cells, breaking it down to oxygen and water. Thus, when this reaction is taking place you will notice that bubbles will form in the test tube. These bubbles is the oxygen gas that is been given off. The presence of the bubbles indicate that the reaction is occurring.
2. YES, THE CATALASE ENZYME WAS PRESENT IN THE PLANT TISSUE THAT WAS TESTED.
The catalase enzyme is present in all plants. The plants need the enzyme to help them breakdown hydrogen peroxide into water and oxygen. This is because the hydrogen peroxide is very toxic to the plant cells and can destroy them, thus the hydrogen peroxide has to be broken down into water and oxygen immediately it is formed.
3. YES, THE CATALASE ENZYME WAS PRESENT IN THE ANIMAL TISSUE TESTED.
In animals, the catalase enzyme is found in great number in the liver. As a result of the metabolic reactions which occur in the liver, hydrogen peroxide is always produce in the liver. The hydrogen peroxide is very toxic to the liver cells and has to be getting rid of on an immediate basis. The catalase is the enzyme which breakdown the hydrogen peroxide into water and oxygen which are not toxic to the cells.
Muscle contraction that results in a change in joint angle is called <span>concentric contraction.
This contraction occurs when enough force that can overcome the resistance applied is developed by the muscle where this force developed is larger than the force of the resistance applied.</span>
