Answer:
The correct answer is desert-dwelling species.
Explanation:
Any preserved remains, trace or impression of anything, which was once living in the past is termed as a fossil. The examples of fossils comprise stone imprints of microbes or animals, bones, exoskeletons, shells, coral, remnants of DNA, the substances getting preserved in amber, and others.
For the formation of fossils, the most essential condition is decomposition that takes place gradually, that is, at a slow pace. Thus, places like wet marshy areas will be the locations where the maximum of the fossils can be found as such places provide optimum conditions for slow mineralization and decomposition of bones.
On the other hand, places like deserts would be the least likely to have a fossil record as deserts are devoid of optimum conditions required for the formation of fossils. In places like a desert, decomposition and demineralization of the components like bones take place at a brisk rate.
A. 1000 grams. 1000 is divided by ten each time it goes up the trophic scale. since it goes up 2, 3 and 4, the answer is 1000. (1000/10/10/10=1)

Explanation:
Sinapsis in biology is a structure in which a neuron cell communicates with another using an electric or chemical sign.
Answer:
B. reduces the amount of water vapor
Explanation:
Tropical rainforests is an area of vegetation comprising of predominantly trees. Trees play a major part in sustaining the environment, and hence, the destruction of trees will result in certain negative effects or impacts on the environment.
One of the effects of destroying rainforests according to the options in the question, is the reduction in the amount of water vapor. Trees in rainforests contribute to the addition of water vapor to the atmosphere via transpiration (loss of water through their stomata). Hence, destruction of tropical rain forests will reduce the amount of water vapor.
