You would expect to find that as the generations pass, the offspring of the Bone-gnawers would have short, wide mouths and strong chewing muscles. The Non-gnawers would have longer, narrower mouths, and weaker chewing muscles. This is because the offspring would inherit the parent's traits, and this would lead to eventual less genetic diversity as the two groups of coyotes inbred more and more. (Sorry if I went further than needed, just trying to be thorough! I really hope that this helps!)
The more plants and animals in a habitat, the greater the biomass, which is now habitats store energy. The greater the number of species the more competition there is for food between predators, which sustains their populations
Answer:
The answer is below
Explanation:
Some of the factors that may lead to poor results in an optimal heat-fixed bacterial smear for staining are the following:
1. Thickness of the smear: In a situation whereby the smear is too thick, it would be impossible to perform adequate decolorization.
2. Quantity of Decolorizer: if the quantity of the decolorizer or reagent is concentrated, the quality of the stain will be affected
3. Age of the culture: Older cultures have multiple ruptured and dead cells, which result in staining Gram-negative.
4. Duration of Decolorization: Overheated smear during heat fixing, often leads to the rupture of cell walls.
The reason it is necessary to heat fix a smear for simple staining is that:
Heat fixing affects bacterial enzymes original state, which hinders their cell digestion parts, thereby leading to the breaking of the cell. The heat also improves the steadfastness of bacterial cells to the slide.
