What makes life on the Earth possible?
Answer:
The balance between the biosphere, geosphere, hydrosphere, and atmosphere make life on Earth possible. Each component of the Earth system interacts with the others to exchange matter and make life possible.
Thats the answer
Explanation:
The factors which makes life on Earth possible are: energy, carbon, water in liquid form, and various other elements such as nitrogen, phosphorus, hydrogen, and most important oxygen.
What are the conditions on Earth?
Earth has a gaseous atmosphere which is responsible for making life possible on the planet. It is the third planet from the Sun. The atmosphere on Earth contains water vapor which helps to moderate our daily temperatures on the planet. The atmosphere contains 21% oxygen, which is necessary for breathing of organisms, and 78% nitrogen.
Earth is present at the right distance from the Sun, which keeps it protected from the harmful solar radiations coming from the sun by the magnetic field, keeps it warm by an insulating the atmosphere, and also has the right chemical ingredients for life, including water and carbon.

Most carbohydrates in the human body are-
A. used as building blocks for proteins
B. used as catalysts for reactions in cells
C. consumed as a source of energy
D. not easily absorbed into the bloodstream
Answer:
C/D
Explanation:
Most of the carbohydrates in the foods you eat are digested and broken down into glucose before entering the bloodstream. Glucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration.

why you add water to Sulphur dioxide and put a blue Litmus Paper in it why does it turns red
Answer:
Because it produce weak acid and acid turns blue lithmus paper to red.
Explanation:
Sulphur dioxide SO2 react to added water to produce acidic product.
When sulphur dioxide react with water, it produce sulphurous acid H2SO3 which is a weak acid.
One of the properties of acid is that they turn blue lithmus papper to red, because the product is an acid, blue lithmus papper turns to red.

What term best describes region “B” of the phospholipid model above?
Answer:
Hydrophobic
Explanation: The phospholipid has a chagred head (Phosphate region) and hydrophobic tails. Lipids are usually nonpolar and hydrophobic. That is why the tails are oriented towards the interior of the membrane.
The two parts 3 and 4 in the region B of the phospholipid model are 3- saturated fatty acids and 4- unsaturated fatty acids.
What is phospholipid model ?
Phospholipids are a class of lipids having significant role in the construction of cell membranes. It is composed of a hydrophilic head with a phosphate group and a hydrophobic tail with fatty acids end.
The fatty acids present in the phospholipid bilayer , are of two types, Saturated and unsaturated. Fatty acids chains without any double bonds or triple bonds are called saturated fatty acid.
Whereas, fatty acid chain with double bonds or triple bond are called unsaturated fatty acids. These two fatty acids chain creates the hydrophobic tail of the phospholipid bilayer.
Hence the region marked as B is saturated and unsaturated fatty acids.
