Answer:
4 amino acids.
Explanation:
To become translated into protein, a sequence is read in triplets called codons.
Each codon that codes for an amino acid is made up of 3 nucleotides.
Therefore, a sequence of 15 nucleotides would be translated into a polypeptide that is made up of 5 amino acids. (15 divided by 3 = 5)
However, we are told that there is a stop codon at the end of this sequence.
A stop codon is a specialised codon that does not code for an amino acid, but tells the protein machinery that the polypeptide is complete.
Therefore, the polypeptide would have 5-1 amino acids, which corresponds to 4 amino acids.
Answer:
Animals in Namibia are organized by their conservation in different zones of this place.
Explanation:
The huge diversity in Namibia’s eco system made it the richest place of South Africa in terms of species that this place have. This ecosystem has endemic species with a number of 14 in it.
To organise these species three biotic sectors in Namibia are utilized, they are- The Southern Savanna, the Southwest Arid and Dessert of Namib.
The wetland ecosystem of Arid is important for many species and the mammals also. The elephant of desert and the black rhinos belongs to the Namibia Dessert ecosystem.
The answer is mitochondrion. Mitochondria are critical for the cell’s biochemical processes that require energy to be powered. Mitochondria are responsible for generating this power in the form of ATP through a process called chemiosmosis. Without ATP, the cell would immediately die since it would be incapable of performing virtually all biochemical processes that re required to sustain life.
Answer:
The correct answer will be option-E
Explanation:
Cyanide is a poisonous substance which is considered the inhibitor of the cellular respiration. The cyanide inhibits the process by inhibiting the complex IV which transfers the electrons to the oxygen thus, block the transfer of the electron.
The isotonic solution is the solution which contains an equal amount of solute to the cell, as a result, no osmotic gradient develops. This leads to the no movement of solute across the semipermeable membrane. When a cell is placed in the isotonic solution, the cell remains unaffected.
Thus, option-E is the correct answer.
Answer:
Explanation:
Photosystems are structural and functional
units of protein complexes that are involved in photosynthesis and carry out the absorption of light and transfer of electrons and energy. The reaction centers of photosystems are made up of structurally different pigments which enables plants absorb light energy at different wavelengths.
