A. objects made of crystals minerals water and air
Process of elimination-
there isn’t organic matter in rocks so D is out
they are made of minerals so B is out
some types of rock (pumice) have air bubbles in them so A is more likely than C
Answer and explanation:
Gram positive bacteria :
1) They retain crystal violet stain thus staining purple
2)They only produce exotoxins.
3)Peptidoglycan is thicker and multilayered
4)Techoic acids are present in their cell walls.
5)Lipopolysaccharides are absent in their cell wall.
6)No periplasmic space present
Gram negative bacteria :
1) They retain red safaranin stain thus stain pink.
2)They produce both exotoxins as well as endotoxins.
3)Peptidoglycan is thinner and single layered.
4)Techoic acids are absent in their cell walls.
5)Lipopolysaccharides are present in their cell wall.
6)Periplasmic space in present.
C. Cycle of life.........................
Answer:
Inducible
Explanation:
When a gene is expressed only under certain conditions such as the presence of an inducer in the environment to inactivate the repressor, the gene expression is said to be inducible. Here, the presence of substance Y is required as it serves as an inducer by inactivating the repressor protein. When the repressor protein is inactivated, RNA polymerase is able to express the gene. This is an example of inducible gene expression. For example, the presence of lactose is required for the expression of genes of the lac operon.
