Answer:
There is no data to show but there would definitely be a decrease in the population of the other organisms in lower trophic level (sea otter).
Explanation:
This question involves an aquatic food chain involving organisms like clams, sea stars, sea otters, and sharks. In this question, the shark appears to occupy the highest trophic level i.e. tertiary consumer. Ideally, as the food chain progresses from the lowest to highest trophic level, the population of each organism decreases.
However, an increase in the population of sharks will mean more mouths to feed on other consumers. Hence, causing a decrease in the population of other organisms in lower trophic level especially the organism that occupies the secondary consumer trophic level.
“Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information. DNA exists in a cell's nucleus within structures called chromosomes .”
Answer:
D
Explanation:
The sand moves from the storage over to the shore/coastline during The summer, therefore, it's D.
The fresh water is in a very big minority when compared to the total amount of water reserves on the planet.
The freshwater accounts for only 2%, while the rest of the 98% are saline water.
But the available freshwater for usage is even less, as from those 2% around 87% is frozen in the ice caps and the glaciers. Around 12% is groundwater, and not all of it is suitable for usage, and only 1% is the freshwater that is the most available from the rivers and the lakes.
This makes the freshwater a prime thing for preservation, as it is what enables the life on the planet, so much more measures have to be undertaken for it to be clean and in healthy condition.
