Answer: water potential is the measure of the energy of water to move from one area to another.
Explanation: water potential effects osmosis in a way that water needs to move through membrane and for this movement it requires pressure which makes water potential high so water movement will be faster across the membrane. Water potential determines water movement in osmosis that water move from high water potential region to low water potential region. If water potential is high inside than outside, then water movement to outside will be more.
If water potential is high outside than inside then water will move more inside. If water potential is the same in and outside then water movement inside and outside will be same and this will be called as equilibrium.
Answer:
Enzymes are specific to particular reactions. There are 4 types of specificity – absolute, group, linkage, and stereochemical. Not all enzymes work on all substrates.
The classical astronomers concluded that heavens were made up of a sphere, because heavens were thought to be perfect and spheres (circles) are a perfect shape. It was Plato who argued that geometrical figures were spheres and everyone agreed to him. It was also believed that the perfect motion of spheres was a uniform circular rotation.
Answer:
Offspring of two different true-breeding varieties are called hybrids.
Explanation:
Pure-breeding plants are plants that self pollinate for many generations and all its offspring had the same features as the parents, generation after generation.
When Mendel cross pollinate this pure-breeding plants with contrasting traits, the offspring is called hybrids because they resulted from a cross between two pure-breeding plants with contrasting traits.
