Answer:
b. passive solar heating
Explanation:
Passive solar heating is a system designed to use solar energy (energy from the sun) for the purpose of providing electricity or heat. This system is used in households and offices to absorb, retain and supply heat to the desired location.
This system is termed "passive" because it does not require any external device for conversion of solar energy rather it exploits sun's energy directly. Hence, according to this question, PASSIVE SOLAR HEATING is the form of renewable energy that uses the sun's energy most directly.
Answer:
Genes play an important role in determining physical traits — how we look —and lots of other stuff about us. They carry information that makes you who you are and what you look like: curly or straight hair, long or short legs, even how you might smile or laugh. Many of these things are passed from one generation to the next in a family by genes. Most cells have one nucleus. The nucleus is a small egg-shaped structure inside the cell which acts like the brain of the cell. It tells every part of the cell what to do. It contains our chromosomes and genes. Chromosomes come in matching sets of pairs and there are hundreds (sometimes thousands) of genes in just one chromosome. The chromosomes and genes are made of DNA.
