El Niño as evidence of potential dangers of global warming to marine ecosystems
Explanation:
El Nino, an abnormal type of weather pattern, causes huge climatic variations globally by bringing floods in one region and drought in another region. These extremely changing patterns in weather can damage human life, agriculture, air quality, natural ecosystems, etc all of which might lead to global warming.
El Nino effect is a serious potential danger to the marine life. This causes variations in the sea surface temperature, ocean currents, and upwelling patterns. Due to this, many marine organisms either migrate to newer places or do not survive the change.
Due to this, other sea animals depended on them also are depleted of their food source. El Nino also impacts the structure of coral reefs causing coral bleaching which in turn affects the marine life.
Answer:
Groundwater is transported through aquifers because of two main reasons: gravity and pressure. In unconfined aquifers, which we concentrate on because they are more likely to be contaminated, water always flows from high points to low points because of gravity.
Explanation:
Xylem and Phloem make up Vascular Tissue.
The correct answer for this question would be the last option. The statement that best describes the reproductive life cycles of ferns and angiosperms is this: <span>The dominant sporophyte phase in the life cycles of both ferns and angiosperms includes the formation of leaves, roots, and stems. Hope this helps.</span>
b.cellular membranes is the answer
