Answer:
Chloroplasts and Cell wall are the components which could be observed using a microscope in a prepared slide of a leaf epidermal cells not in a prepared slide of himan cheek cells.
Explanation:
Chloroplasts is commonly known as a plastid which are contained in plants. Chloroplasts contains chlorophyll and in the process photosynthesis is processed.
Cell wall is generally known for the surrounding of the cell as a border. Cell wall is located just outside the cell membrane.
extinction would lead to the extinction of other forms of life. A keystone species helps to
support the ecosystem of which it is a part.
An example of what can happen when a keystone species is removed occurred when fur
hunters eliminated sea otters from some Pacific Ocean kelp beds. Otters eat sea urchins,
which eat kelp. With its major predator gone, sea urchin populations exploded and
consumed most of the kelp. Fish, snails, and other animals associated with the kelp beds
disappeared.
The grizzly bear is another example of a keystone species. Grizzlies transfer nutrients
from the ocean ecosystem to the forest ecosystem. The first stage of this transfer is
performed by salmon that swim up rivers, sometimes for hundreds of miles. Salmon are rich
in nitrogen, sulfur, carbon, and phosphorus. The bears capture the salmon and carry them
onto dry land, scattering nutrient-rich feces (wastes) and partially eaten salmon carcasses.
It has been estimated that the bears leave up to half of the salmon they harvest on the
forest floor.
Which sequence best represents the feeding relationships in a kelp ecosystem that has not been disturbed
by humans?
(1) sea urchins → kelp → fish (3) kelp → sea otters → sea urchins
(2) kelp → sea urchins → sea otters (4) sea urchins → snails → kelp
The correct sequence displaying the feeding relationships in an undisturbed kelp ecosystem is: kelp → sea urchins → sea otters. Kelp serves as a food source for sea urchins, which in turn are consumed by sea otters.
The sequence that best represents the feeding relationships in a kelp ecosystem that has not been disturbed by humans is (2) kelp → sea urchins → sea otters. In an undisturbed ecosystem, the kelp, being a producer, forms the base of the food chain. Secondly, the sea urchins, as primary consumers, feed directly on the kelp. And finally, the sea otters are secondary consumers that prey on the sea urchins, maintaining the balance in the ecosystem.

The answer is false.
Answer:
hypertonic
Explanation:
During a hurricane, the plants in freshwater marshes die because the invading saltwater is hypertonic (B), meaning it has a higher solute (salt) concentration. This causes water from inside the cells to move out into the surrounding saltwater, which can lead to the cells losing so much water that they die.
During a hurricane, salt water invades fresh water marshes causing many of the plants to die and ultimately the loss of soil. This is because the salt-water solution is Hypertonic to the plants, which ends up drawing water from the plant cells.
A hypertonic solution has higher solute concentration (in this case, salt) than the inside of the plant cells.
Given that osmosis is the movement of water from an area of lower solute concentration to an area of higher solute concentration, the water inside the cells moves out into the surrounding saltwater, which can result in the cells losing too much water and dying.
