Answer:
b
Explanation:
The reactants are sunlight, water and carbon dioxide and the products are oxygen are sugar.
The layer which protects the earth is referred to as magnetosphere.
Magnetosphere is termed as the region of space which surrounds astronomical object by way of magnetic fields.
They create planets which generates planets in magnetic field which include fields where they can occur in stars through interaction of plasma.
Magnetosphere blows away particles from the earth and also from the sun.
Answer:
double membrane
Explanation:
Chloroplasts are surrounded by a double membrane similar to the double membrane found within a mitochondrion.
Answer:
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat-trapping causes changes in the radiative balance of the Earth-the balance between energy received from the sun and emitted from Earth-that alter climate and weather patterns at a global and regional scale.
Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years. Natural Factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.
