Answer:
A
Explanation:
<em>The active state of cell division covers the prophase, metaphase, anaphase, and telophase. The total number of observed cells that were undergoing cell division can, thus, be calculated by adding the number of cells in each stage of the cell division.</em>
Total number of cell in division = 20+4+2+4
= 30
Probability that a randomly chose cell will be undergoing cell division = <em>number of cells in division/total number of cells</em>
= 30/200
= 0.15 or 15%
The correct option is, therefore, A.
Answer:
The E zone portion of the protein
Explanation:
The glucagon hormone which is a signal molecules that triggers a reaction in the liver cells is most likely to bind to the E zone extracellular portion of the G-protein-coupled receptor. This then changes the conformation of the receptor activating the heteromeric G proteins.
<span>The answer is Each stage produces ATP, but only the first stage occurs in the cytoplasm. Cellular respiration consists of three stages: 1. Glycolysis which takes place in the cytoplasm, 2. Krebs cycle which takes place in the mitochondria, and 3. Electron transport chain which takes place in the mitochondria. During each step, ATP is produced.</span>
It retains salt and water within the circulation
