Answer: It is the DORSAL BODYCAVITY that is completely surrounded by bones and provide very good protection to the structure it contains.
Explanation:
Body cavity is that the space that contain fluid in the animal body. Cavities house the organs and structures. The two largest body cavities are ventral and dorsal body cavities.
The dorsal body cavity consist of cranial and spinal cavities and they are completely surrounded by bones that provides protection for the structures it contain.
The ventral cavity consist of abdominopelvic and thorasic cavities. The ventral cavity and the organs it accomodate are lined by a thin covering of serosa membrane
Answer:
Nitrification
Explanation:
Nitrifying bacteria in the soil convert ammonia into nitrite (NO2-) and then into nitrate (NO3-). This process is called nitrification. Compounds such as nitrate, nitrite, ammonia and ammonium can be taken up from soils by plants and then used in the formation of plant and animal proteins.
Answer: Option D
Most bryophytes lack true root and leaves.
Explanation:
Bryophytes are group of non vascular land plants that are found in moist environment. Examples are mosses, liverworts and hornworts. They reproduce by spores and not by flowers. They different from other plant in that they lack true roots, stems and leaves, presence of rhizoids function as roots to anchor the plant to the soil but the rhizoids does not absorb nutrient like other plant root.Bryophytes differ from other land plant in that they do not have xylem, a vascular system use to transport water internally rather they get water and nutrients through their leaves.
Answer:
Advantages: Wind turbines do not actively create green house gases, wind is an indirect solar energy (which means it never runs out), and it has a fairly high net energy
Disadvantages: NIMBY effect (not in my backyard, it means people support it, but they don't want to be near it), transportation and construction of materials cause greenhouse gases, and wind turbines can kill/harm birds and bats
Explanation:
Gathering, constructing and transporting materials to build wind turbines releases green house gases, because of vehicle's combustion and factory emissions. However, wind turbines rely on a renewable resource that a) never runs out, and b) is a clean source of energy. Compared to nonrenewable energy sources, wind is a good energy source.
Energy, growth, evolutionary and ecological describe different biological life cycle. Life cycle involves all those living organisms in the earth. Life cycle involves energy that every living organisms need, growth that every living organism undergo, evolution and ecological.
