embryonic stem cells could serve as a model to evaluate the physiological effects of environmental pollutants efficiently and cost-effectively.
Patent ductus arteriosus occurs when the normal fetal circulation conduit between the pulmonary artery and the aorta fails to close and results in increased pulmonary blood flow. The clinical manifestations of patent ductus arteriosus include; Murmur; wide and bounding pulse pressure, Asymptomatic Heart failure.
Explanation:
It contains chlorophyll which the plant uses for photosynthesis when there is sunlight.
Transpiration also occurs on the leaves.
Answer: Oceans
Explanation:
Climate is primarily determined by the interaction between air and ocean. The warm wind circulate and makes the temperature feasible for life.
Oceans heat the air above it and it circulates from the equator region to the polar region to make the temperature optimum. The circulation of air due to ocean leads to climate change.
hence, these two factors are responsible for the climate of a region.
