Density can be useful in identifying substances. It is also a convenient property because it provides a link (or conversion factor) between the mass and the volume of a substance. Mass and volume are extensive (or extrinsic) properties of matter - they depend on amount.
Paleontology deals with fossils and helps in learning the changes of living organisms in sequence.
Biogeography deals with the distribution of species across the mother earth.
Embryology deals with the study of the similarities and difference that exists in the embryos of different species or organisms.
Anatomy deals with the study of the similarities and difference that exists among different species or organisms.
<u>Explanation: </u>
As an organism dies, the remaining of these organisms will be buried in soil. These are fossils. Paleontology supports evolution with the information that are related to the fossils, footprints etc. With these we can study the evolution of organisms and also the changes they undergo. There are some technologies like radiometric dating that can be used for the determination of these rocks and fossils ages.
Charles Darwin suggested that the evolution of species were form their ancestor. Biogeography supports evolution by explaining about the distribution of different species over the earth. Embryology and Anatomy supports evolution by describing about the similarity and difference in the species of living organisms. Embryology deals with the embryos and anatomy deals with the structure.
<u>Answer:</u>

<u>Explanation:</u>

Green roof do have several advantages over ordinary roofs as follows.
<h3><u>Explanation:</u></h3>
Green roof are defined as the roof over which a thin layer of soil is placed to grow a thin layer of grass or other plants. This have several advantages as follows:
A. Green roof help in reducing water logging in roofs, thereby reducing the dampening of the concrete, and increasing the longevity of the roof.
B. It is actually energy saving, by reducing the summer temperatures by evaporation and transpiration. It also maintains a warm room temperature in winter by reducing the heat loss.
C. It's also actually low in budget. Its initial cost is more than ordinary roof, but the maintenance cost is very low, if not nill.
D. Its a place for recreational activities. Greenery in urban areas are very rare sight, which can be met through this project.
E. Green roofs provide a chance for urban agriculture.
Answer:
Major structural differences between a plant and an animal cell include: <u>Plant cells have a cell wall, but animal cells do not. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not.</u>
