Answer:
Scientist come to know about the land feel by various measures such as quantity of methane gas, quantity of radioactive materials, etc. They collect data from a particular area and checks it whether it is under critical range or not.
Explanation:
Land-filling is a process by which all the waste which is solid is buried under the ground. It is also a type of land pollution. It degrades the land quality. The land is no more fertile to grow crops. some of the waste are also radioactive which harmful effect the animals and plant living in that area. It also tends to have the humans living nearby that area. this area is also capable of creating methane gas which is very explosive in nature.
Scientist plays an important role for finding out the critical condition of land. They also have instrument which are very helpful for finding out the critical range of the radioactive materials.
Answer:
The correct answer is - Western fence lizard
, Xenopus (African clawed frog)
, Fruit Fly
, Turtle
, and Sea urchin.
Explanation:
An ectotherm is an organism that also known as the cold-blooded animal. Such animals experience body temperature regulation based on the external atmosphere or condition like sunlight and other condition.
This group includes a different group of animals such as reptiles, amphibians, fishes, and invertebrates. From the given options the cold-blooded animals or ectotherm are known are - Western fence lizard
, Xenopus (African clawed frog)
, Fruit Fly
, Turtle
, and Sea urchin as their internal physiological conditions does not play a major role in regulation of body temperature and external conditions play a major role.
Thus, the correct answer is - Western fence lizard
, Xenopus (African clawed frog)
, Fruit Fly
, Turtle
, and Sea urchin.
Those options are very odd because none of those options are the reason the planets in out solar system revolve around the Sun. The real reason is because the Sun's gravity is pulling on the planets. However, if I had to choose one it would be the Sun is the most massive object in out solar system.
