Answer:Fossils provide evidence for the evolutionary change through now extinct forms that led to modern species. For example, there is a rich fossil record that shows the evolutionary transitions from horse ancestors to modern horses that document intermediate forms and a gradual adaptation o changing ecosystems
Explanation:
Global warming is one of the greatest environmental change right now. In effect, in cold climate countries, the pest population would increase since there will be more pest activity when there is enough heat to warm the pest. In summary, the process of global warming will most likely warm the cold climate of temperate-situated countries.
Answer:
Explanation:All cells in the body need to have oxygen and nutrients, and they need their wastes removed. These are the main roles of the circulatory system. The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.
Blood
Blood consists of:
Red blood cells – to carry oxygen
White blood cells – that make up part of the immune system
Platelets – needed for clotting
Plasma – blood cells, nutrients and wastes float in this liquid.

Answer:
True.
Explanation:
Prokaryotes and eukaryotes shows various similarities as well as differences among themselves. The eukaryotes have well defined nucleus whereas such nucleus is absent in prokaryotes.
Prokaryotes are much smaller in size than eukaryotic cells. The small area has large surface area to volume ratio. This ration helps in the process of diffusion and metabolism in prokaryotes. Due to their small size, prokaryotes have large surface area to volume ratio than eukaryotic cells.
Thus, the correct answer is option (a).
Explanation:
Pangea
Pangea is the belief that all continents were all connected at one time
