Primary productivity is a term used to describe the rate at which plants and other photosynthetic organisms produce organic compounds in an ecosystem. There are two aspects of primary productivity. hope this helps!
Answer:
C. All living things are made up of at least one cell.
Explanation:
A cell is a structure formed of carbon-based molecules with the cytoplasm inside the membrane which contains the bio-molecules needed to survive like the proteins, DNA, enzymes, and others.
The structures when studied by the Schelidnen in plant cells and Schwann in animal cells concluded that the living organisms are composed of the cells and cell is the smallest unit of life as it is the functional and structural unit of life and formulated the cell theory.
Since all living organisms are composed of the cell, therefore, Option-C is the correct answer.
Both pH and Heat effect catalase function therefore we will measure the function based upon changing these variables.
Fish fossils occur in sediments deposited underwater. That could be sea bottom, lakes, or rivers. Generally, seabottom sediments are raised to the surface by tectonic uplift. Also, when sea level falls during ice ages, sea bottom sediments are exposed to the atmosphere.
