Answer:
He examined covered and uncovered meat to determine that maggots came from eggs.
Explanation:
Prior to Redi's experiment and other supporting experiments, it was formerly believed that life could emanate from non-living things, for example, the generation of maggots from rotting meat.
In 1668, a scientist called Francesco Redi disproved the idea of spontaneous generation. He did this when he experimented that the maggots from meats are only as a result of eggs laid by flies when they perched on the meat.
He placed the meat in two jars; an uncovered jar and another in a covered jar with a cloth, after several days, the uncovered jar had maggots on the meat, while the covered jar had no maggot on the meat, but on the cloth. With this experiment, he was able to demonstrate that the maggot arose from the eggs of the flies, not the meat itself which is nonliving and hence, disproved the idea of spontaneous generation.
Answer:
The fungicide destroys mycorrhizal symbionts.
Explanation:
Mycorrhizal symbionts is the symbiotic association that is present between plants and fungi. Plants provide food materials in the form of sugar to the fungi while fungi fixes phosphorus for the plant that is present in the soil in unavailable form. When fungicide is sprayed, it kills the fungi present in the soil and deficiency of phosphorus occurs in plants.
The first answer is B and the second is C Because half of the kids will be homozygous black, and the other half Heterozygous white.
Answer:
An Endoplasmic reticulum
Explanation:
A living organism can either have prokaryotic or eukaryotic cells.
Eukaryotic cells have a defined nucleus and other membrane bound organelles whereas prokaryotic cells lack membrane bound organelles such as mitochondrion and chloroplast.
Endoplasmic reticulum are membranous system that forms a system of flattened sacs in the cytoplasm.
These organelles can only be found in eukaryotic cells and not prokaryotic cell.
