Answer:
Veins
1l carry blood from tissue of the body to the heart
2) are usually found closer beneath the skin
3) are less muscular then arteries
4) collapse if blood flow stops
arteries
1) carry blood back away from the heart to the tissue of the body.
2) found deeper within the body
3) are more muscular then veins
4) would generally remain open even if blood stops because of it's muscular structure.
Phosphorus is an essential nutrient for plants and animals. Phosphorus is a limiting nutrient for aquatic organisms. Phosphorus forms parts of important life-sustaining molecules that are very common in the biosphere.
Answer:
Fluid lava (which is less viscous because it has less silica content) flows much further than viscous lava (that is high in silica content). Therefore, this types of lava forms shield volcanoes – low slopes and low height- because they flow over longer distances before they cool. Viscous lava from composite volcanoes that are high in height and have steep slopes.Explanation:
The reaction which connects monomers (polymerization) is dehydration synthesis.
The name tells you about the nature of the reaction - dehydration means 'loss of water', correct? When two biological monomers connect, one gives up a hydrogen ion (H+), and the other gives up a hydroxyl group; (OH-). They combine to form H2O - water.
Answer:
The key difference between Golgi apparatus and endoplasmic reticulum is that the Golgi apparatus is not directly associated with the nucleus while some parts of the endoplasmic reticulum are continuous with the nuclear envelope. Golgi apparatus and endoplasmic reticulum are two very important organelles present inside the cells.
