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:
E. Large molecules
Explanation:
Large molecules cannot pass through the membrane without help they are too big. This is because the membrane is very selective with what it let enters.
Answer: A population has a small size high level or genetic drift and very little migration into the population what will most likely happen to the genetic diversity in the population over time?
Explanation: Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.Genetic drift may result in the loss of some alleles Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster
Answer:
there are all kinds of signals occur in the brain
Explanation:
Hope this help not sure if it is the right answer
Answer:
The missing answer choices are:
a. hypotonic
b. isotonic
c. osmosis
d. hypertonic
The correct option is <u>d. hypertonic</u>
Explanation:
A hypertonic solution has a higher concentration of solutes than the concentration of solutes present inside the plant. As there is a difference in concentration between the inside and the outside of the plant, the plant loses water in an attempt to balance the difference. As a result, there is an excessive loss of water that dehydrates the plant and kills it.
