Answer:
a,c,d
Explanation:
Crossing over occcur when genetic material is exchanged between homologous chromosome this leads to formation of new genes that creates diversity.
homologous chromosome assort imdependently i.e seperate from each other leading to the formation of an entirely new gene that creates diversity.
Genetic recombination when gene recombines together to produce a unique type. It occurs between different species.
Answer:
Food insecurity
Explanation:
Food insecurity is a situation that occurs when people do not have adequate reliable access to enough healthy and nourishing food which they require for their growth and development and an active and healthy life. Food insecurity causes famine and hunger. Certain factors such as lack of food, instability, inappropriate utilization and insufficient access over a particular period of time may result in food insecurity.
Answer: S- phase of cell cycle
Explanation:
Cell cycle is a cyclical process taken place in a cell leading to duplication of its DNA and division of cytoplasm to form two daughter cells.
The S phase of a cell cycle is an important part of the cycle which is found during interphase stage before either mitosis or meiosis.
The S phase of cell cycle is responsible for the replication of DNA. This replication DNA causes it to double before it enters mitosis or meiosis.
Answer:
Methane is a chemical compound with the chemical formula CH4, symbolizing one atom of carbon and four atoms of hydrogen. It is a group 14 hydride and the simplest alkaline, and is the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Methane naturally occurs both below ground and under the seafloor, and is formed by both geological and biological processes. In nature, methane is produced by the anaerobic bacterial decomposition of vegetable matter under water. Methane is important because it can be captured from landfills, can be burned to produce electricity, heat buildings, or power garbage trucks. Methane can also be captured from farm digesters, which are big tanks that contain manure and other waste from barns that house livestock such as cows and pigs. In fact, Jordan Dairy Farms in Massachusetts uses a biodigester to turn cow manure into methane gas, which is used for fuel or turned into electricity.
