Top predators are often keystone species in their habitat. Explain what happens to the biodiversity of an ecosystem when a top predator is deliberately removed from the ecosystem in which it lives.
Answer:
The ecosystem will fall out of balance.
Explanation:
The ecosystem will fall out of balance because once you remove the top predator, the plant eaters will grow in numbers, they will eat all of the vegetation, and will either need to adapt or die. Predators are very important, as is everything in the food chain

Discribe the structure of paramecium
Answer:
The widest part of the body is below the middle. The body of a paramecium is asymmetrical. It has a well-defined ventral or oral surface and has a convex aboral or dorsal body surface. Its whole body is covered with a flexible, thin and firm membrane called pellicles.
Explanation:
c) In dense rainforest, plants that grow close to the forest floor tend to have lower rates of photosynthesis than the very tall trees. Suggest why this might be.
Answer:
The reason why plants that grow close to the forest floor tend to have lower rates of photosynthesis is because sunlight is a vital component in the production of glucose. Using logic, you can see that the tree cause larger shadows to form—blocking sunlight.

Describe how the destruction of a habitat by a natural disaster might affect species diversity ?
Which event in a star's life cycle can create heavy metals like gold, platinum, or lead?
Organisms become extinct for many reasons. All BUT one is reason for extinction. That is
A) adaptations.
B) over-hunting.
C) climate change.
D) habitat destruction.
Answer:
A) Adaptations
Explanation:
If a species learns to adapt to their environment, then they will not become extinct
Answer:
adaptation
Explanation:
When a organism adapts to its surroundings it docent become extinct instead it survives. It wouldn't make sense that if it were to adapt then it would be extinct. While over hunting is a cause of extinction and so is climate change if the organism is not well adjusted to any temperature. Habitat destruction is also a cause of extinction because it kills the organisms home causing them to not have anywhere to live. So adaptation is the correct answer.
a 4.24 kg marble slab has a volume of 1564 cm^3. what is it's density in g/cm^3? give you answer to the nearest tenth
Thhe density of the marble, given the data from the question is 2.7 g/cm³
What is density?The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
With the above formula, we can obtain the density of the marble. Details below
How to determine the density of the marbleThe following data were obtained from the question:
Mass of marble = 4.24 Kg = 4.24 × 1000 = 4240 gVolume of marble = 1564 cm³Density of marble =?The density of the marble can be obtained as follow:
Density = mass / volume
Density of marble = 4240 / 1564
Density of marble = 2.7 g/cm³
Thus, the density of the marble is 2.7 g/cm³

Please Help! Which terms describe the periwinkle snails? Select all that aply more than one answer!
a. herbivores
b. heterotrophs
c. secondary autotrophis
d. members of the second trophic level
e. carnivores
f. primary consumers
Answer:
a, b, d, and f.
Explanation:
The periwinkle snails feed on plants. Consequently, they are said to herbivorous and heterotrophic since they cannot manufacture their own foods. They are also referred to as primary consumers because they directly feed on plants without any other nutritional option. They, therefore, occupy the second trophic level on a typical food web.
The correct options are a, b, d, and f.

If carrot sticks are put into water and refrigerated, they become turgid and stiff, but if red blood cells are given the same treatment, they burst or lyse. Explain the difference in the results.
Answer:
Because carrot isn’t the same matter as a red blood cell so if a blood cell gets cold it bursts
Explanation:
They have different chemical compounds
The carrot cells become turgid whereas red blood cells burst or lyse in the given condition due to plant cells have two organelle that prevents it from lysing which are, the cell wall and a large vacuole.
Plant cells have a cell wall around their cell membrane and have a single large vacuole whereas in animals the cell wall is absent and found small vacuoles.
When water moves into a plant (carrot) cell, the vacuole becomes bigger. it causes pressure on the cell wall and increases the turgor pressure within the cell making it stiff. The pressure occurred by the cell wall prevents too much water to enter and prevent cell lysis.It lacks in the animal cells that results in cell lysis due to too much water enters in it.Thus, the difference, in this case, is due to plant cells have two organelle that prevents it from lysing which are, the cell wall and a large vacuole.
