Answer:
The most appropriate answer would be D. The western skink population would be separated into two groups, and genetic diversity would decline in each group.
It can be explained with the help of a bottleneck effect due to which population size decreases suddenly due to events like a natural disaster, habitat destruction et cetera.
The construction of the multi-lane highway would have destroyed the natural habitat of western skinks and separate them into two populations.
The separation of a population along with the destruction of habitat would result in a severe decrease in the population size of western skinks.
Consequently, the genetic diversity would also decrease.
The organelle which is most likely to be missing from leaf cells is Lysosomes.
Lysosomes are an important organelle for eukaryotic animal cells as they contain the digestive enzymes. The macromolecules or foreign matter which are harmful for the cells enter the animal cells easily but not the plant cells as the plant cells contain cell walls. Phagocytosis or digestion of macromolecules is not much needed in plant cells so a lysosome can be missing from the leaf cell.
B. I did a project on scorpions a few years back.
Answer:
if you are not using alcohol (95% ethanol), you are not decolorizing the wall of the gram-negative bacteria, which should get rid of the violet color, therefore the safranin stain, in the next step, won't be absorbed in the wall, and the bacteria will end up being purple due to the previous crystal violet stain of the gram-positive bacteria
Explanation:
Plants adapt in different ways depending on if they are submerged or floating. Floating plants feature a waxy upper surface, which helps to repel water. The upper surface also contains the chlorophyll needed for photosynthesis. Submerged plants employ a different water circulation system; instead of running water though stems, they absorb water and nutrients from the surrounding habitat. The roots of a submerged plant are primarily for anchorage and not for sourcing nutrients. This prevents them from being swept away by the currents.
The marine biome is the largest in the world, covering close to 70 percent of the earth's surface. It is also home to the most diverse collection of life: scientists have discovered over a million plant species living in this biome and estimate that there are still nine times this amount yet undiscovered. Many of the plants in this habitat rely on photosynthesis for nutrition. Algae is a particularly important plant, as it is responsible for the production of nearly half the oxygen on the planet.
