Answer:
Meat is the only one of the above answers that cannot be composted.
Explanation:
Meat is something that can be composted but it can easily bring maggots and flies. It can also bring cats and dogs. It also slows down the composting process.
C. Is the correct answer I believe
Answer:
plants use photosynthesis to make food.
Explanation:
Photosynthesis takes place in the specific cells of plants known as chloroplasts, which are the cell type found in leaves. A single chloroplast is like a suitcase full of major photosynthesis materials. It has water-soaked from the root of the plant, atmospheric leaf absorbed carbon dioxide and chlorophyll in softened, labyrinthine organelles known as Thylakoids.
The true catalyst for photosynthesis is chlorophyll. This light-sensitive molecule is used to stimulate the process by cyanobacteria, plankton, and terrestrial plants.
The chlorophyll molecules are so awful for the green light to absorb that they reflect it like small mirrors that cause the majority of the leaves to look green. In the autumn we only look at these limitless colors of yellow and orange formed in carotenoid pigments after chlorophyll degradation.
Answer:
Option C
Explanation:
The cyanobacteria is the oldest life form that once existed on planet earth some 3.7 billion years ago. These cyanobacteria formed layered structures fossils which are called as stromatolites
Hence, stromatolites are the fossilized colonies of cyanobacteria.
A set of rocks in Greenland show the evidence of cyanobacteria as a living organism.
These stromatolites have layered structure of bio-chemical accretionary that are produced by trapping sedimentary grains through biofilms of microorganisms such as cyanobacteria.
Hence, option C is correct
