You read a description about a woman named Tyra, who happens to be extremely beautiful and almost six feet tall. You are asked to predict whether Tyra is a model or a science teacher. To do this, you think of your prototypes of a model and a science teacher, and you decide that Tyra is a model. Your reasoning may be faulty due to:

a. an algorithm.
b. framing.
c. the availability heuristic.
d. the representativeness heuristic.

the availability heuristic

Explanation:

Heuristic means a practical way of solving a problem, learning or discovering something. In this example there are only two facts available: Tyra is extremely beautiful and almost six feet tall. Therefore your practical prediction is based on what is available, and that leads you to the prototype of a model... but you can be wrong!  

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
