The greenhouse effect is the effect where carbon dioxide (usually from factory gas emissions, car exhaust gas, etc) gets sent into the Earth's atmosphere , however, instead of disappearing, it gets trapped under the atmosphere of the Earth and cause the temperature of the planet to rise. The temperatures rise since the radiation of the sun's rays gets trapped under the layer of carbon dioxide. This affects climate change since when the globe warms up, our earth begins to warm up too resulting in colder parts of the earth to rise in higher temperatures than usual.
The correct answers are I and IV
There are three main effects of complement :
1. Lysis of cells such as bacteria and tumor cells.
2. Generation of mediators that participate in inflammation and attract neutrophils to the site of infection, an event called chemotaxis.
3. Opsonization i.e. enhancement of phagocytosis.
Lysis of pathogens by complement involves the insertion of a special substance called the membrane attack complex into the cell membrane of the pathogen which disrupts or punctures the membrane as a result of which water and electrolytes enter the pathogen and it dies.
Generation of mediators known as C5a and C567 complex attract neutrophils.
if there is a source of water and single celled organisms, life will be possible on that planet. The planet will need a atmosphere so 1. it will have its own gravity 2. and so that gas molecules ( including oxygen) will not be able to escape into space. the world population will be roughly 10.7 billion people so the planet will need to be spacious. A planet as described would be perfect if you take the right measures. if it has single celled organisms than its proven that it can and will sustain life. So, the planet has a water source, contains living organisms, is spacious, and has a atmosphere.
Abiogenesis is another name for spontaneous generation.
