Reinforcement and support
parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis, secretion, food storage, and other activities of plant life. Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) and collenchyma (living support tissues with irregular walls).
Answer:
Explanation:
Natural selection is based on Darwin’s observation that individuals most likely to survive and reproduce are those with traits best suited to their current environment.
Earth's surface wind generally blow from regions of higher AIR PRESSURE TOWARDS REGION OF LOWER AIR PRESSURE.
The direction in which the wind blow on the earth surface is a product of many factors, the most important of these factors are: pressure, friction and Coriolis effects. On the earth surface, the wind normally blow from high to low pressure. A high pressure system followed by a low pressure system allows the wind to flow in clockwise direction outward toward a low pressure system. This ensures the continuous flow of the wind.
