Answer:
From the translation of the mRNA molecule 5’ AUG AGU CCU CUU UGA 3’ results the amino acid sequence Met-Ser-Pro-Stop, that is, Methionine-Serine-Proline and the last triplet being a stop codon.
Explanation:
Messenger RNA (mRNA) molecule is in charge of conducting the encoded genetic information to produce the protein synthesis, organized in a sequence of nucleotides called the genetic code. The arrangement of the nucleotides is in triplets of bases or codons, which encode the synthesis of an amino acid (translation), determine the beginning of the synthesis and also establish the stop.
In the given sequence, 5’-AUG-AGU-CCU-CUU-UGA-3’ results the amino acid sequence Met-Ser-Pro-Stop:
- <em>5'-AUG</em><em> Methionine (Met), being at the same time an initiating codon.</em>
- <em>AGU</em><em> Serine (Ser).</em>
- <em>CCU</em><em> Proline (Pro).</em>
- <em>UGA-3'</em><em> is a stop codon.</em>
<u>Stop codons do not code for amino acids, but their presence in a codon sequence marks the completion of peptide or protein synthesis</u>.
Commensalism- A whale and barnacles
Mutualism- The Oxpecker and the Rhino, the rhino provides a place for the Oxpecker to perch, while the Oxpecker eats all the bugs and parasites off the rhino.
Parasitism- A tick on a deer, and potentially harming the deer. The tick gains while the deer loses.
Answer:
Photosynthetic Organisms are classified as Photo-autotrophs.
Explanation:
Autotrophs are those organisms that can produce their own food and also called primary producers. While photo-autotrophs are those that use the process of photosynthesis to produce food. The common examples of photo-autotrophs are plants and Cyanobacteria.
Photosynthesis is a procedure in which an organism produces energy in the form of food using sunlight, water, carbon dioxide and Chlorophyll. The main products of photosynthesis are glucose and Oxygen.
Answer:
b.
Explanation:
Natural Selection refers to the survivability of organisms based on different traits or genes that they have which then get passed on to their offspring. Based on this information we can say that a population of mountain gorillas in which individuals with genes for long hair survive the cold better is the situation in which natural selection is most likely to occur. This is because longer hair in this scenario is a gene that drastically affects the chance of survival for the gorillas and will most likely be passed on to their offspring.

The correct answer is (A): joint
A joint is a type of fracture in the earth’s crust where the rocks breaks without movement. It is generally caused by tensional forces. Since there is no movement in the joint, hence land stays in the same place. Joint fractures can be systematic and regular or joints may be non-systematic and irregular.
