The major causes of losses of species are as follows:
  • Loss of habitat
  • Over-exploitation and hunting animal species for selfishness.
  • Excessive deforestation
  • The introduction of exotic or alien species which cause competition between the new species and local species.
  • Co-extinction where if one species get extinct then other dependent species will also get extinct.

In the sequence that unfolds after molecules of a hormone such as ABA bind to receptors at the surface of a target plant cell:a. first messenger molecules in the cytoplasm are mobilized, then G proteins carry the signal to second messengers such as protein kinases, which alter the activity of cell proteins such as IP3.b. binding activates G proteins, which in turn activate second messengers such as IP3; subsequent steps are thought to involve activation of genes that encode protein kinases.c. binding activates phospholipase , which in turn activates G proteins, which then activate molecules of IP3, a step that leads to the synthesis of protein kinases.d. binding stimulates G proteins to activate protein kinases, which then bind calcium channels in ER; the flux of calcium ions activates second messenger molecules that alter the activity of cell proteins or enter the cell nucleus and alter the expression of target genes.e. binding activates G proteins, which in turn activate phospholipase ; this substance then stimulates the synthesis of second messenger molecules, the second messengers bind calcium channels in the cell's ER, and finally protein kinases alter the activity of proteins by phosphorylating them.
