Explanation:
Messenger RNA (mRNA) is a single stranded RNA molecule, complementary to one of the DNA strands in a gene. The mRNA is a version of the RNA in the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made. During protein synthesis, an organelle called a ribosome moves along the mRNA, reads its sequence of bases, and uses the genetic code to translate each triplet of three bases or codon, into its corresponding amino acid.
The answer is no, they are just two varieties of the same species adapted to different environment.
The change in moth color was caused by natural selection which favored the color more suitable for a certain conditions. Thus, in dark background, dark-colored moths could camouflage and escape from the predator (birds). So their chances for the survival and reproduction were higher than those of light-colored moths. When the pollution was reduced, the light colored moths were beneficial for survival.
So, the conclusion is that changes in the environment caused changes in the characteristics that were most beneficial for survival.
Biological domain Animalia is <u>heterotrophic</u>
Answer: Option B
<u>Explanation:</u>
The Animalia kingdom follows the heterotrophic mode of nutrition which means it depends on other organisms for their nutrition while autotrophs produce their own food. Carbon is the main source of energy. The heterotrophs get carbon from consuming these organic resources.
The cells are eukaryotic and they are multicellular organisms.They do not have a cell-wall. They intake large molecules and using their different organ system break down the food into simpler substances which provides nutrition and energy for the organism to survive.
Protein-energy malnutrition is a form of undernutrition caused by an extremely deficient intake of calories, protein, or both. Two examples of this type of malnutrition are kwashiokor and marasmus. Protein-energy malnutrition is more often caused by decreased absorption or abnormal metabolism. It is defined as a range of pathological conditions arising from coincident lack of protein and/or energy in varying proportions. The condition vary in forms ranging from mild through moderate to severe degrees.
