Answer:
Species a and c
Explanation:
The species c, was more closely related to species a than species b was. This is because species a and c just recently evolved into different species in evolutionary history.
Answer:
the fossils are examples of... mineralization
The fossils tell us that polar regions... formed a supercontinent that divided and slowly drifted to polar regions
Explanation:
Mineralization is a type of fossilization where rich-mineralized water fills the pores of the dead tissues for a long time. Subsequently, when this water is evaporated, the excess of minerals is deposited on the tissues, thereby mineralizing organic tissues.
Fossils enable us to understand more accurately past climatic conditions from regions where these fossils were found. For example, the discovery of plant fossils closely related to tropical species in polar regions suggests that these regions were once a part of a super landmass known as Pangea that divided and drifted a long time ago (millions of years ago).
Answer:
Explanation:
The closed metal container will get distorted or compressed due to a combination of two reasons:
1.<em> contraction of the metal container as a result of a reduction in its temperature.</em>
2. <em>a reduction in the pressure inside the container caused by a sudden drop in the temperature of the water inside it. </em>
The tap water causes a reduction in the temperature of both the container and the water inside it. An increase in temperature causes metal to expand and a reduction in temperature causes it to contract. Also, water takes less space than steam. Therefore, a reduction in the temperature of the hot water causes a reduction in the pressure inside the container relative to the outside. This causes the metal container to be compressed.
