Answer:
Explanation:
A keystone species is the one which plays an important role in maintaining the structure of the ecosystem. On the keystone species many other species of the ecosystem are dependent upon.
The potential effects associated with the keystone species includes the following:
1. No other species will be capable of filling the same ecological niche. Hence, the dependent organisms will suffer and the ecosystem will change drastically.
2. The ecosystem will be populated by the invasive species which will affects the population of native species.
Answer:
In terms of adaptation, fitness refers to the ability of an organism to survive and reproduce in a constantly changing environment.
Adaptive traits are very much important in a constantly changing environment as they increase the chances of survival of a population in the environment.
For example, Darwin's finches adapted to develop different types of beaks in order to get nutrition in different environments. Long necks of giraffes are also considered as a result of adaptation which helps them get the food located high on trees.

Check the c in the explanation
Explanation:
a) RNA has three components - 1) 5 - carbon ribose sugar (2) phosphate group (3) nitrogen base
RNA polymerase is an enzyme involved in transcription where genetic material DNA is transcribed into RNA ( mRNA,rRNA,tRNA).
b) the dependent variable here is what we are looking in the experiment , here it is number of nuceotides per second ,the transcription efficiency of RNA polymerase. And the two controls are important wild type without drug and experimental strain without drug these two tells about baseline of transcription rate of an enzyme. so that one can explain the drug effect on a enzyme.
c) In both wild type and exp strain upon treatment with amanitin the transcription rate decreased in exp strain it is not significant whereas in wild type the effect is much higher compare to exp strain and it is significant. this suggests that the mutation in experimental strain must be on larger subunit of the RNA pol enzyme. that mutation might be showing effect of binding drug to the enzyme and also has a role for its enzyme activity.
and the reduction of transcription rate is 100% efficient in wild type compared with exp strain.
d) a null hypothesis is a general statement in a statistics where there is no measured phenomenon between groups.
the change in the amino acid is an important clue, tells that there is no effect in transcription rate between experiment strain with and without drug . which in turn tells that the mutation is imp for the activity of the Enzyme for its role.

Answer:
The process by which volcanoes vent water vapor, carbon dioxide, nitrogen, and other substances is called outgassing.
