Carbon dioxide and oxygen are
differentially exchanged between the atmosphere and the oceans in the carbon
cycle. An increase in atmospheric carbon dioxide also raises the carbon dioxide
absorbed by the oceans. This increases the pH of the ocean waters which consequently
affects the growth of phytoplankton. Low pH affects negatively the growth of phytoplankton.
The clarity of the waters would, therefore, increase with pH due to low
plankton growth.
Answer:
Improving drainage in the cities by ensuring that drainage channels are large enough to handle flood waters and that they are never blocked. Clogged drainages impede flow of water resulting to a rise in water levels in the city.
Ensure proper enforcement of laws that ensure that people do not settle on wetlands and riparian land. Wetlands are natural drainages for water and settling on them is akin to blocking drainages in a built environment.
Constructing flood gates and flood walls to redirect floodwaters away from populated areas. This is especially implemented in built environments that are in low-lying lands and prone to flooding.
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division. There are three forms of nondisjunction: failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis.[1][2][3] Nondisjunction results in daughter cells with abnormal chromosome numbers (aneuploidy).
Answer: b. stretching toward the sun
Explanation:
The deciduous forests are the biome which exhibit four distinct seasons such as winters, spring, summer and fall. Summers are warm and winters are cold.
Leaves are the main food producing organs of the plants and trees. The deciduous trees exhibit broad leathery leaves which are stretched towards the sun. Their shape allows them to obtain maximum sunlight so as to make food in the form of carbohydrates (sugars) by the process of photosynthesis. The leaves are adapted to synthesize food in all the seasons. As, in winters the deciduous trees may receives low sunlight.
