Air is essential for almost all organisms.
Explanation:
Uranium-235 is the answer
Organic compound is generally any chemical compound that contains carbon. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. Study of the properties and synthesis of organic compounds is the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonates and cyanides), along with a handful of other exceptions (e.g., carbon dioxide), are not classified as organic compounds and are considered inorganic. No consensus exists among chemists on precisely which carbon-containing compounds are excluded, making the definition of an organic compound elusive.[1]Although organic compounds only make up a small percentage of the Earth's crust, they are of central importance because all known life is based on organic compounds. Most synthetically produced organic compounds are ultimately derived from petrochemicalsconsisting mainly of hydrocarbons.
Answer: Responsible for formation of reproduction cells/gametes
Explanation: Meiosis is significant because it makes sure that all organisms (which were produced via reproduction) contains the correct number of chromosomes. Also, Meiosis produces genetic variation by the process of recombination.
The female flowers mature before the male flowers, resulting in self-fertilization being preventing
