Chloroplast Functions: Photosynthesis
Neither the peptide hormones or the metabotropic neurotransmitters such as the catecholamines, can enter their target cells. They bind to surface receptors, which then activate second-messenger systems in the cell. Peptides hormones are the hormones that consist of amino acids; they can be among the intracellular signalling peptides and proteins, and can include insect hormones, gastrointestinal hormones and thyroid hormones, but their actions are not limited to individual cells and they can act systemically.
<h3>Answer;</h3>
Climatic limitations of the area
<h3><u>Explanation;</u></h3>
- Climatic climax is a stage in which the plant species live in perfect balance with the current environmental conditions. Although climate is the major influence on vegetation at a global scale, on a local scale other factors such as drainage, geology and relief affect plant growth.
- In the process of ecological succession, one community replaces another until a climax community is established. The type of climatic vegetation that grows in a certain geographical area is most directly influenced by a climatic limitations of an area.
- <em><u>A climax community is able to exist in a certain geographic region for a long period of time because it remains in equilibrium with the environment.</u></em>
- <em><u>Ecosystems tend to change with time until a stable system is formed. All stable ecosystems are characterized by the presence of a specific climax vegetation influenced by the climate of the area</u></em>.
