Answer:Fossil Record
Explanation:
Fossils provide evidence that organisms from the past are not the same as those found today, and demonstrate a progression of evolution. ... The resulting fossil record tells the story of the past and shows the evolution of forms over millions of years.
Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants. The totality of fossils is known as the fossil record.
The fossil record, however, is quite incomplete. Here's one major reason why: Sediment has to cover an organism's remains in order for the long fossilization process to begin. ... So like the mineralized bones themselves, the fossil record is an incomplete framework that scientists flesh out through additional methods.
Explanation:
1. Stomata are the openings on the leaf for the exchange of the water and air from the plant to the environment. It actually helps plants to breath, so it can also be seen as nostrills of the plants. They are present on either side of the leaves. Opening a stomata is like opening the doors for the exchange of the gases . This comes at a cost.
Due to sunlight and heat from the environment water content of the leaf is also remarkably lost when stomata opens, which is protected otherwise due to outer waxy layer of the leaf. To reduce this, most of the stomata are present on the lower surface of the leaves, as it will reduce the possibility of water loss due to high sunlight during the afternoon.
2. In aquatic plants you can find most of the stomata present on the upper surface of the leaf. As the plants float on the water surface, its lower epidermis is stuck to the water, hence respiration is least likely there as there is no contact of the stomata with the air.
Wind blowing across the surface of the ocean is the major mechanism that generates most ocean surface waves. the movement of two liquids with different densities creates most waves.
