Answer:
Given:
UUU- phenylalanine
CUA- Leucine
GCU-Alanine
AAA-Lysine
a) mRNA sequence or codons for the short peptide with amono acid sequence of lys-ala-phe-leu would be:
mRNA (Codons) 5’-AAA-GCU-UUU-CUA-3’
b) tRNA anticodon for the same amino acid sequence lys-ala-phe-leu on the base of mRNA 5’-AAA-GCU-UUU-CUA-3’ would be :
tRNA (Anticodons) 3’-UUU-CGA-AAA-GAU-5’
c) base sequence that would be found in the DNA double helix which carries the gene for this peptide -
5’-AAA-GCT-TTT-CTA-3’ Coding DNA Strand
3’-TTT-CGA-AAA-GAT-5’ Template DNA Strand
When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. Habitat loss is perhaps the greatest threat to organisms and biodiversity.Extinction happens when environmental factors or evolutionary problems cause a species to die out. The disappearance of species from Earth is ongoing, and rates have varied over time.
The correct answer is: an interaction between the biosphere and the geosphere.
The geosphere represents all of the rocks, minerals and ground that are found on and in Earth. It includes the ocean floor, all of the rocks on the surface, and all of the sand in the deserts.
Biosphere on the other hand is composed of all the living organisms on Earth (including human).
