True.
The earth is made of several subsystems or spheres that interact to form a complex and continuously changing (dynamic) state that is termed as the earth system.
Even though the earth system is a closed system, it self regulates through the subsystems such as the water cycle and carbon cycle.
The earth system is characterized by numerous overlapping cycles in which matter is recycled over and over again. Cycles involve multiple spheres and systems interactions. Humans impact and are impacted by the cycles in various ways.
1. Evaporation , sublimation, transpiration
2. Increase temperature
3.
Answer:
Normal Gene: AUC AUA GGA AAA UAC
Mutated Gene: AUC ACA GGA AAU UAC
Explanation:
The transcription takes place in the nucleus. This process involve copying of DNA sequence into mRNA (messenger RNA) sequence. mRNA too consists of 4 nucleotides except the fact that in mRNA the thymine (T) is replaced by uracil (U). This involves the following steps:
- Unwinding of DNA
- Binding of RNA polymerase to the unwinded DNA.
- Synthesis of RNA commonly mRNA
- RNA elongation
- Stop codon (UAA, UAG, UGA) initiating termination of synthesis of RNA
