<em>The process of evolution occurs only in populations and not in individuals... Five forces can cause genetic variation and evolution in a population: mutations, natural selection, genetic drift, genetic hitchhiking, and gene flow.</em>
Answer: Leaves are adapted for photosynthesis and gaseous exchange.
Explanation: They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. Although these design features are good for photosynthesis, they can result in the leaf losing a lot of water. The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapor can then escape from inside the leaf.
Answer:
Cyclic forms
Explanation:
The hydrates of carbon are called carbohydrates. Carbohydrates are known as saccharides. The simplest carbohydrates are the monosaccharides such as glucose, fructose. Monosaccharides are the units of polysaccharides such as starch, cellulose. Polysaccharides are long chains of monosaccharides joined by glycosidic bonds in cyclic form. The glucose molecules in polysaccharides are linked in the cyclic form. It is formed when the hydroxyl group on carbon 5 linked to the aldehyde carbon 1 .
A. Plants use capillarity to move water from their roots to their leaves.
Answer:
Cell surface receptors (membrane receptors, transmembrane receptors) are receptors that are embedded in the plasma membrane of cells. They act in cell signaling by receiving (binding to) extracellular molecules. They are specialized integral membrane proteins that allow communication between the cell and the extracellular space.
