Answer : Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether.
<h3><u>Answer;</u></h3>
D) Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.
<h3><u>Explanation;</u></h3>
- <em><u>Mutations are sudden, random changes that occur spontaneously in the genetic make up of an organism.</u></em> Mutation are caused by various factors which includes errors in meiosis, and other factors such as chemical mutagens.
- <em><u>Mutations may be beneficial and may play an important role in evolution as they are raw material of genetic variation</u></em>. <em><u>Mutations may lead to genetic variations in the genetic make up of an organism . Therefore mutations are important to mutation since they create new DNA sequences for a given gene and thus resulting to new alleles.</u></em>
Answer:
The answer to your question is V2 = 0.92 l
Explanation:
Data
Volume 1 = V1 = 2.4 l
Pressure 1 = P1 = 1.5 atm
Temperature 1 = T1 = 273 °C
Volume 2 = V2 = ?
Pressure 2 = 4.5 atm
Temperature 2 = 313 °K
Process
To solve this problem use the Combined gas law
P1V1/T1 = P2V2/T2
-Solve for V2
V2 = P1V1T2 / T1P2
-Substitution
V2 = (1.5 x 2.4 x 313) / (273 x 4.5)
-Simplification
V2 = 1126.8 / 1228.5
-Result
V2 = 0.92 l
