The farther layers of earths crust
You can tell the vein from the others by holding the leaf up to a light. This makes the leaf a bit see through and the veins will be clearly visible as they do not become semi-transperent. You can also put paper on top of the leaf and rub gently over the paper with crayon to see the veins. They will make darker or lighter lines on the paper depending on if you have the leaf facing up or down.

Answer:
Wind is the horizontal movement of air. All wind is caused by the uneven heating of Earth's surface, which sets convection currents in motion. Convection currents on a large scale cause global winds; convection currents on a small scale cause local winds.

Answer:
peptide and protein hormone
Explanation:
Peptide and protein hormones are composed of amino acids with latter being longer in length. They are synthesized in rough endoplasmic reticulum where they undergo various modifications like N terminal signal sequence removal and glycosylation to form prohormones. These prohormones are sent to golgi apparatus where they are packaged in secretory vesicles. In response to a stimulus the appropriate vesicle is released via exocytosis.
They can show regulated secretion where the hormone is stored in vesicles for a long time and then released in large amount in bursts for a proper stimulus. Sometimes they also show constitutive secretion where they are released slowly and steadily by the vesicles.
