Answer:
Diffusion
Explanation:
Diffusion is the spontaneous movement of gases, without the use of any energy or effort by the body, between the alveoli and the capillaries in the lungs.
Answer:
e) endocytosis
Explanation:
Because the ATP concentration inside the cell is dropping, we know that the cell is using energy to transport the polar molecule into the cell. This eliminates a), b) and c) because they all don't require energy, and we know that polar substances have trouble diffusing across membranes because the tails of the phospholipids making up the membrane are hydrophobic and non-polar. We also know that the polar substance concentration is increasing in the cell. Honestly, both d) and e) would work because both require ATP; however, endocytosis is more specific as a hypothesis. Thus, e). :)
Answer:
B) transcription and translation.
Explanation:
DNA is the genetic material and stores genetic information. The genetic information stored in DNA is expressed in the form of genetic traits by two processes: transcription and translation. The template strand of DNA is copied into RNA strand by the enzyme RNA polymerase. The process is called transcription and occurs in the nucleus.
The RNA formed by the process of transcription serves to carry the genetic information to the cytoplasm. The mature RNA, mRNA leaves the nucleus in eukaryotes and joins ribosomes in the cytoplasm to serve as a template for protein synthesis. The process of protein synthesis is called translation as it translates the genetic information of mRNA into the amino acid sequence of proteins. Translation and transcription occur simultaneously in prokaryotes.
