Answer:
a. No discrepancy is present; organisms that contain an outer membrane and periplasmic space should stain pink because of their cell wall composition.
Explanation:
Gram stain is the staining method used to differentiate bacterial species into two groups, gram-positive and gram-negative bacteria. Factors that will differentiate gram-positive from gram-negative include the coloration of bacteria, the composition and chemical and physical properties of cell walls. In these tests, bacteria that have an outer membrane and a periplasmic space are considered gram negative and pink in color (sometimes similar to red) due to their cellular composition. For this reason we can state that there is no discrepancy present in the bacteria exposed in the question; Because this bacterium has an outer membrane and a periplasmic space, then it is normal for the bacteria to turn pink due to its cell wall composition.
Answer: The observation clearly shows that certain behaviors are genetically controlled
Explanation:
From the observation, the Fishers bird uses long strip while the Peach-faced uses short strips and there offspring uses intermediate. It is an indication that the behavior of the length of strips cut by the bird is under genetic control and it can also be concluded that both the Fisher bird or Peach-face bird does not have complete dominance over length of strips cut for nest making.
Answer:
E. digestive system
Explanation:
Mollusks/Molluscs are<u> invertebrates</u> of the <em>Kingdom Animalia</em>. It is said to have the <em>biggest population </em>when it comes to the <em>marine phylum. </em>
It has an organ called the "radula" that is responsible for grinding food. This organ looks like a tongue. Its "crystalline style" is located in the middle part of its gut. It is responsible for secreting enzymes and it helps in extracellular digestions.
Clearly, <u>the </u><u>radula</u><u> and</u><u> crystalline style</u><u> are both part of the</u><em><u> mollusc's digestive system.</u></em>
