An ecosystem is a community of living organisms and the nonliving components of the environment Energy flows in an ecosystem in

one direction through food chains, and a food web is made up of all the food chains within a community of organisms. Biodiversity refers to the variation in species found within an ecosystem, and it is measured in two ways: (1)
species richness, which is the total number of different species in an ecosystem; and (2) relative abundance, which is a measure of how common each species is within the ecosystem
Imagine that carnivore D represents the sea lamprey in the Great Lakes ecosystem. This invasive species has been present there
since the 1800's yet the ecosystem has remained stable. How can you explain this?
A) The sea lampreys are indigenous to salt water and have a very short life
span
B) There are complex feeding mechanisms at work to protect the other
species in the food web.
C) The sea lampreys only feed on one type of fish so they have only depleted
that single population.
D) Marine scientists have developed a method to effectively remove the
Lampreys from the Great Lakes.

High concentrations of solutes such as sugar or salt results in plasmolysis of cells due to the onset of which phenomenon. Selec
malfutka [58]

Answer:

The correct answer will be option-B

Explanation:

Three types of solution are formed based on the concentration of the solute which are:

1. High solute concentration- Hypertonic solution

2. Low solute concentration- Hypotonic solution

3. Equal solute concentration- Isotonic solution

When a cell contains a high amount of solute concentration and low concentration of water then it results in the generation of very high osmotic pressure.

If a cell is placed in an aquatic medium then due to high osmotic potential, the water will enter the cell which will lead to the rupture of the cell membrane. This process of rupture of the cell membrane is known as the plasmolysis.

Since the cell rupture due to the generation of very high osmotic potential, therefore, is the correct answer.

A go cart rolling at a speed of 2 m/s begins to accelerate down an inclined street at a constant rate of 1.5 m/s¶. It takes the
sammy [17]

Answer:

11\frac{m}{s}

Explanation:

As per the Newton's first law of motion,

v = u + at\\

where "v" is the final speed

"u" is the initial speed

"a" is the acceleration

and "t" is the time taken

Substituting the given values in above equation, we get -

v = 2 + (1.5)*6\\= 2 + 9\\= 11 \frac{m}{s}\\

The cart be traveling at a speed of 11 \frac{m}{s} by the time it reaches level ground.
