Answer:
The most significant experiment performed to date on the formation of organic molecules remains that of Miller and Urey in 1952 when they sought to test the hypothesis of Oparin and Haldane that the organic building blocks of life emerged from a reducing atmosphere (Miller, 1953). Miller filled a flask with the four gaseous elements of the reductive atmosphere: methane, ammonia, hydrogen and water. He then passed electrical discharges through them to simulate lightning. After 125 h of the experiment, using the equipment available to him at the time, Miller identified several alpha amino acids contained within the residues.
Answer: sagittal plane
Explanation: sagittal plane is one of the body planes,the others are coronal and transverse.
The sagittal plane divides the body into left and right portions.
Dividing the body into plans is important in the study of anatomy as it helps in precision of the part of the body under consideration and it prevents errors.
Answer:
Increase the membrane surface area which creates more work space
Explanation:
Mitochondrion (Plural-mitochondria) is referred to as the powerhouse the the cell because it is the site of ATP (energy rich compound) synthesis in the cell. Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes; the outer membrane, which sheds the organnelle and contains it like a skin and the inner membrane, which folds over many times and creates a layered invagination called CRISTAE.
The folding of the inner membrane increases the membrane surface area inside the organnelle. Since many of the chemical reactions e.g. Cellular respiration (ETC and Chemiosmosis) occur in the inner membrane, the increased surface area creates more space for the reactions to occur.
It is just reasonable that the more the space, the more the work that can be done.
For the answer to the question above, <span>Lipid Rafts are subdomains of the plasma membrane it contains high concentrations of cholesterol and glycosphingolipids. It exists as distinct liquid-ordered regions of the membrane that are resistant to extraction with non-ionic detergents.
So the statement above is <u>"NOT TRUE OR FALSE" </u>

The human eye has three types of cone cells. These cones respond to the light and its varying signals wavelengths determines how the brain will perceive the lights signals and determine the colors the person sees.
Damage to any one of the types of cone cells doesn't cause total blindness because they have independent structure and are parallel to each other. Instead, damage to any one of the types of cone may cause COLOR BLINDNESS.
