Answer:
False
Explanation:
If this were indeed accurate, it would threaten the internal balance of our cells; akin to how not all keys fit in locks, not every molecule possesses the "key" needed to transport across the phospholipid bilayer into and out of the intracellular and extracellular fluids. Typically, small hydrophobic ("water-repelling") molecules can traverse this bilayer.
Response:
Termites contribute to the formation of mounds which help in soil aeration and moisture retention, aiding the growth of various plants such as shrubs, grasses, and trees.
Their mounds, along with the droppings, supply phosphorus and nitrogen, enriching the soil and promoting the growth of grasses, shrubs, and trees.
Reasoning:
These insects are prevalent in the Savanna regions of Africa and construct mounds from their feces, saliva, and soil.

Answer:
This is due to a lack of proteolytic enzymes.
Explanation:
The diagnostics from the study indicate that protein digestion in the small intestine occurs at a slow rate, primarily because of either the absence or a significant reduction in proteolytic enzymes. These enzymes are crucial for enhancing the digestion speed, resulting in the production of amino acids that are subsequently absorbed into the bloodstream for muscle formation.
Answer: Transcription and translation enable tRNA and rRNA molecules to produce a diverse range of polypeptides.
Explanation:
DNA comprises the genetic instructions for protein synthesis, and this data is transmitted to mRNA during transcription. This initial phase of gene expression entails copying a portion of DNA into RNA (mainly mRNA) facilitated by the enzyme RNA polymerase.
Both DNA and RNA are types of nucleic acids that utilize nucleotide base pairs as a complementary code. During transcription, an RNA polymerase reads a DNA sequence, generating a corresponding, antiparallel RNA strand termed a primary transcript.
A notable variation exists among genes, leading to numerous distinct mRNA molecules. However, ribosomes, made up of rRNA, play a crucial role during translation. This phase occurs in the cytoplasm or ER, where proteins are synthesized after the DNA-to-RNA transcription within the cell's nucleus. This entire process is recognized as gene expression.
Among the three forms of RNA, tRNA is the smallest, consisting of only 75 to 95 nucleotides, and functions to transport specific amino acids to the developing polypeptide chain. It can be concluded that mRNA enhances the variety of polypeptide structures by carrying essential information regarding their synthesis.
The appropriate answer is - C. genus and species. The scientific nomenclature of an animal reflects its genus and species. The first part denotes the genus, which in this instance is Canus, while the second part indicates its species, here being nipponicus. All living beings are categorized systematically: kingdom, phylum, class, order, family, genus, species. For instance, if we consider the wolf as an example, its classification is as follows: Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Carnivora, Family: Canidae, Genus: Canis, Species: C. Lupus.
