GLASS HOUSE EFFECT

GLASS HOUSE EFFECT

Greenhouse Effect or the Greenhouse Effect is a term that was originally derived from the experience of farmers in temperate climates who grow vegetables and seeds in the greenhouse. Their experience shows that in the daytime when the weather clears, even without the heater in the room temperature in the greenhouse is higher than the temperature welcome.

This occurs because sunlight is reflected back through the glass by the plant / soil in the greenhouse space as a form of infrared rays heat. The reflected rays can not get out of the room so that the greenhouse air in the greenhouse temperature rises and the heat trapped in the greenhouse room and not mixed with the air outside the greenhouse.

Biodiversity 1. Various Level Biodiversity

1. Various Level Biodiversity

Biodiversity can occur at various levels of life, ranging from low levels of organisms to high-level organisms. Example of single-celled creatures to many-celled creatures; and organizational levels of individuals living up to the level of complex interactions, such as from species to ecosystems.

In general, biodiversity is divided into three levels, namely:
1. Gene diversity
Every living organism trait controlled by a pair of hereditary factors (genes), one of the other parent of the male and female parent. This level of diversity can be shown by the variation in one species.

example:
- Variations of coconut: coconut ivory, green coconut
- Variations of dogs: a bulldog, shepherd dog, mongrel
What makes this variation is: The formula: F = G + L

F = phenotypic
G = genoti
L = environmental

If G changed for some reason (mutation, etc.) or L changes there will be a change in F. Change is what causes this variation.
