Answer: When two homologous chromosomes transfer genetic information in prophase 1.
Explanation:
Meiosis is a process in which the a single parent (diploid) cell divides twice to produce four haploid daughter cells which have half the number of chromosomes as that of their parents.
Crossing over can be defined as exchange of genetic material that occurs between the chromosomes of opposite germ line. This process helps in transfer of mixing of traits to the offspring from both parents. This occurs in prophase 1 stage of meiosis. This process is the basis of formation of gametes or sex cells that are eggs in female and sperm cells in the male. The paired homologous chromosomes from single parent align to form a bivalent so that cross over each other and a unique combination of trait develop after this process.
Answer:
We fear flying in a plane, nuclear power plants or being struck by lightning more because our risk perception isn't rational. We assess risks using a mixture of cognitive skills (weighing the evidence, using reasoning and logic to reach conclusions) and emotional appraisals. In this case, we believe that overheating or lack of exercise is something we can control. We believe we can feel the process taking place and we can react in time. We fear all the situations that we cannot control.
Explanation:
Answer;
Keep the reactants in separate containers.
Explanation;
-According to the collision theory of reactivity, reactions occur when reactant molecules effectively collide. For an “effective collision” to occur, the reactant molecules must be oriented in space correctly to facilitate the breaking and forming of bonds and the rearrangement of atoms that result in the formation of product molecules.
