Answer:
1)Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.
2)Speciation is the process by which new species form.

Explanation:
The absence of vascular tissues in nonvascular plants make these plants grow without a rigid structure (stalks, stems, and leaves). These plants grown on the ground or on the trunk of trees. Examples of these plants are mosses, hornworts, and liverworts.
Answer:
receptor down-regulation
Explanation:
Downregulation is a control mechanism by which a cell decreases the amount of a cellular component, such as RNA or protein, in response to an external variable. In contrast, a reactive increase of a cellular component is called upregulation. An example of downregulation occurs when insulin binds to its receptor and the complex is endocyted in the cell in response to hormonal signaling.
Because Photosynthesis is the process used by plants and some bacteria to create energy from sunlight. ... Cellular respiration uses glucose, or sugars, from food molecules and turns them into carbon dioxide.
