The central nervous system controls the functions of the body and mind. It consists of the brain, spinal cord, and neurons. It is the most important system of the body.
Answer:
Genes are passed down to children by the process of meiosis. Meiosis includes gametes (sex cells). Most cells in our body are diploid, they have 23 pair of chromosomes (46 in total). 23 come from our father and 23 from our mother. The gametes are haploids, which mean that they only have one copy of each chromosome. The gametes are formed by meiosis, which leads to genes being passed onto children. Meiosis is where a normal diploid cell divides to make four non-identical haploid cell. First, each chromosome makes a copy of itself. The pairs of chromosomes line up and divide. The two new cell divide again creating 4 new daughter cells, each with a single set of chromosome. Each new sex cell has a combination of the genetic material from the mother and the father. Now when a sperm fertilises and egg, a new combination of chromosomes are created. This is a diploid cell, which then divides to create a zygote (baby). The baby now has the genes (genetic material) from the parents.

Answer
Practices that can support a circular economy are;
• Ensuring there is high efficiency in use of available resources
• Cutting down the wastes production
• Practicing maximum recycling of wastes
• Using other business models such as focusing on changing consumer behaviors
Explanation
A circular economy is one that focuses more on changing the consumer behavior of using activities that consumes the scarce resourcesto developing a design from waste system which will have positive outcomes to the society. For example , moving towards embracing renewable energy resources through keeping goods and material in use, continuous generation of natural systems and designing out wastes and pollution.
Taskmasters. Land breezes occur at night and in the early morning.This winds occur when the land is cooler than the sea. This happens when the air cools in the night time (as there is less heating from the sun) it contracts
