While studying enzyme kinetics in the lab, a scientist observed that the rate of a reaction involving enzyme amylase increased as the concentration of starch increased. With further increase in starch concentration, the amylase activity did not change. Why did this happen?

Answers

Answer is: The enzyme amylase was saturated, as all its active sites were occupied by substrate starch.

Given how the process of evolution appears to occur, how might concepts presented in this unit be used to help predict how any given organism might evolve in the future? How might this knowledge lead to human intervention, positive or negative, in that organism’s natural evolutionary process?

Answers

A general ballpark how one can predict the way how evolution will work in the future would be by thinking about the requirement of a certain area or environment and which changes would be necessary and relevant for any organism to thrive with its new changes.

This could help people speeden up this process by enabling organisms to develop such traits faster, as well as ourselves.

(4) a decrease in the proportion of the population

Answers

Evolution can be defined as the heritable changes occurring in the populations over the time through the successive generations. The process of evolution is helped by the natural selection of the favorable traits and the elimination of the unfit traits from the environment. An increased proportion of favorable characteristics in the offspring will show the proof of successful evolution.

Hence, the correct answer is 'option 3 - an increase in the proportion of offspring with favorable characteristics'.

Explanation:

Fossil fuel dependence is associated with _______.a. environmental consequences
b. economic consequences
c. development hindrances
d. all of the above

Answers

The correct answer for the question that is being presented above is this one: "d. all of the above." Fossil fuel dependence is associated with environmental consequences, economic consequences, and development hindrances.

Answer: d. all of the above

Fossil fuels such as coal, oil and gas are beneficial sources of energy used by the human society. Fossil fuels are non- renewable resources, which are produced after millions of years of geological and biological activity taking place inside the earth crust. Human society is mainly dependent upon the fossil fuels to maintain it's energy needs.

There are some negative consequences associated with fossil fuels:

Environmental consequences: Fossil fuels are used for generation of energy in the power plants and by the automobiles. These sources releases partially and completely combusted products which includes the poisonous gases causing air and water pollution.

Economic consequences: Fossil fuel use is related with economic crisis because fossil fuels are non- renewable resources, which cannot be replenished once used. They are expensive and many commercial energy generation processes are dependent on them such as electricity, transportation and others.

Development hindrances: Large dependence on fossil fuels creating an hindrance on development process. As, there are very few findings which are resulted which could replace the fossil fuels, these finding can be beneficial for the environmental and economic point of view.
