The best answer is d - Water.
Plasma is a water solution that is pale yellow in color in which all other parts of the blood are suspended.
Plasma is made up of approximately 92 % water. Proteins, enzymes, glucose, amino acids, minerals, urea, vitamins, uric acid, antibodies, salts and hormones make up the remaining 8% .
Whole blood is composed of 55% plasma. Plasma in blood acts as a solvent for gases, electrolytes, nutrients and important proteins vital to life.
<span>It traps emissions close to Earth’s surface due to the Inversion Layer (Warmer air) being trapped between two colder air pockets having no where to go, and in effect the emissions also cant go anywhere because they are also trapped by the layers</span>
Answer:
10 units
Explanation:
Energy is transferred from organism to organism in an ecosystem when they feed on one another. However, based on the pyramid of energy, only about 10% of energy is transferred from one organism to another because a bulk of energy (about 90%) has been lost to metabolic activities.
Energy moves from producers to consumers, each occupying trophic levels. If the first trophic level in an energy pyramid receives 1,000 units of energy from the sun,
- 10% of 1000units will be available for the second trophic level i.e. 10/100 × 1000 = 100units
- 10% of 100units will be available for the third trophic level i.e. 10/100 × 100 = 10units
Hence, 10units of energy is available for the third trophic level.
The answer should be A, inside the bag.
Permeable means allowing certain material to pass through. So if it's permeable to water and iodine, it means it can allow water and iodine to pass through the bag, but doesn't allow starch to go in.
Because iodine can pass through the bag, it can get into the bag filled with starch. But since starch couldn't diffuse out of the bag, the color change is only can be observed inside the bag. When no starch is gone out from the bag, there is no color reaction in the rest of the beaker.
So that answer is A.
Answer:
During a chemical change, the composition of matter always changes. Four possible clues to chemical change include a transfer of energy, a change in color, the production of a gas, or the formation of a precipitate.
