Living indicators are species that are sensitive to changes in the environment. For example air pollution can be monitored by looking at lichen, which are sensitive to sulphur dioxide in the air. The number of lichen at a particular location indicates how clear the air is. Similarly, mayfly larvae are good indicators for water pollution because they're sensitive to the concentration of dissolved oxygen in water.
Non-living indicators are things like satellites which can measure the temperature of the sea surface, weather stations that measure atmospheric temperature, rain gauges to measure rainfall, and dissolved oxygen meters to measure concentration of dissolved oxygen in water.
Answer:
Histidine- Proline- Tryptophan- Stop codon
Explanation:
The mRNA strand in the question is produced as a result of a process called TRANSCRIPTION. However, the mRNA transcript is further used to synthesize an amino acid sequence in a process called TRANSLATION. The mRNA sequence is read in a group of three nucleotide bases called CODON.
Each codon specifies an amino acid which is represented in the GENETIC CODE. In this case, a sequence of mRNA strand is given as: CACCCAUGGUGA
The following codons in the sequence specify the following amino acid:
CAC - Histidine
CCA - Proline
UGG - Tryptophan
UGA - Stop codon
Hence, the amino acid sequence encoded by the given mRNA strand is Histidine- Proline- Tryptophan- Stop codon.
N.B: After a stop codon (UGA, UAA, UAG) is encountered, the translation process stops.
Answer:
Polygenic traits are controlled by a number of separate genes.
Hope it helps! :D
Hello there,
Natural photosynthesis is more effective as it is utilizes energetically efficient primary events of light capture and charge separation.
But Actual photosynthesis is used to help natural photosynthesis
Hope this helps :))
