Answer:
In meiosis I, the arrangement of any homologous chromosome along the center plane ( forgot the name for this) is independent of the arrangement of the other homologous chromosomes. There is thus equal probability for the chromosome to be in either of the two daughter cells after meiosis I. This is observed in meiosis 2 metaphase as well where the arrangement of each Sister chromatid about the ‘center plane’ is independent of each other. This independence observed during metaphase of meiosis I and meiosis II allows for chromatids to be in either gamete formed in equal probability, not affecting by other chromatids thus inheritance of one trait is not affected by the inheritance of another trait.
Answer:
Fertilizers are man-made inorganic salts used to replenish nutrients in the soil.
Answer:
Exothermic because it doesn't take place inside something, rather on the outside. :)
Answer:
The relationships include symbiosis, predation and competition.
Explanation:
Organisms relate with each other in different ways in the environment. Such relationships include:
Competition: This deals with the struggle between organisms for food and other available resources. The strongest and fittest usually have a higher chance of survival.
Predation: This is the process by which bigger animals prey on smaller animals for food. This helps in movement of energy in the trophic levels and also the balancing of the eco system.
Symbiosis: This is a mutual relationship in which two organisms form a type of partnership and benefit positively from each other.
