Answer:
If a population exceeds carrying capacity, the ecosystem may become unsuitable for the species to survive.
Explanation:
It has been estimated that if the carrying capacity of the earth was 12 billion people, by 2050 this number be reached.
What do you mean by carrying capacity?"Carrying capacity can be defined as a species' average population size in a particular habitat."
How do you determine carrying capacity?Carrying Capacity can be determined by:
Formula. K = r * N * (1-N) / CP.
r = Rate of Population Increase (%)N = Population Size.CP = Change in Population Size.What factors influence carrying capacity?"Factors that influence carrying capacity are food availability, water, and space."

As in any essay, the first paragraph of your argumentative essay should contain a brief explanation of your topic, some background information, and a thesis statement. In this case, your thesis statement will be the statement of your position on a particular controversial topic. You are making a claim! You are making a claim on the following question: "Are human activities the primary reason for the composition of Earth's atmosphere, or is it the effect of natural phenomena?"
Which statement describes a factor that determines which plants come first or second or third during ecological succession?
A.) how long it takes for animals to return
B.) the year the disturbance occurred
C.) which animals are present
D.) differences in the needs of plants, such as nutrients or sunlight
Answer:
I believe it is D.
Explanation:
Ecological succession has to do with how the habitat changes over time. So D would make the most sense.
The statement describes a factor that determines which plants come first or second or third during ecological succession is differences in the needs of plants, such as nutrients or sunlight. Thus, option D is correct.
What is Animal kingdom?
The amount of voids and open space within a rock or sedimentary deposit is known as its porosity; the higher the porosity, the better the rock or sedimentary deposit is at holding water. Typically, sediments are more permeable than rocks.
Because there is more open space between the individual sediment grains than between the minerals in a crystallized rock, sedimentary rocks tend to be more porous than igneous rocks.
Sand that is loose has a porosity of about 40%; compacted and dewatered sand has a porosity of 15%; and sand that has been lithified into sandstone rock by the development of cement between the sand grains has a porosity of about 5% or less.
Therefore, The statement describes a factor that determines which plants come first or second or third during ecological succession is differences in the needs of plants, such as nutrients or sunlight. Thus, option D is correct.

QUICK! [This is the stem.]If each circle represents the cell membrane of an animal cell, which diagram correctly shows the movement of materials by osmosis?
Diagram A correctly shows the movement of materials by osmosis.
Osmosis can be defined as the net movement of a fluid (e.g., water) across a semipermeable biological membrane.Osmosis movement is due to different concentrations of one or more solutes on both sides of the cell membrane. Osmosis does not require energy to move substances across the membrane.In conclusion, Diagram A correctly shows the movement of materials by osmosis.

Write a scientific explanation determining which unknown is the solid,which is the liquid, and which is the gas.
Answer:
best answer I could find, hope it helps
Explanation:
Difference between Solid Liquid and Gases
Highly Strong intermolecular forces between the molecules, leads to a definite volume in Solids.
The intermolecular forces are stronger than gases but weaker than solids.
The intermolecular forces are practically non-existent. Thus, there is no definite volume.
Solids have a definite shape to them. Liquids do not have a definite shape.
Gases do not have a definite shape.
The intermolecular space between solids is absent.
The intermolecular space is moderate but present.
The intermolecular space is free-flowing and plenty.
The force of attraction between the molecules is incredibly high.
The force of attraction between molecules is pretty moderate.
There is no intermolecular force of attraction between the molecules.
They are incompressible.
Liquids cannot be compressed.
Gases can be compressed quite easily.
Solids have a definite shape and volume.
Liquids have a definite volume.
Gases have no definite volume.

Explain one way that a large rock becomes a small rock. In your explanation include the name and description.
Answer:
Erosion
Explanation:
Erosion is the withering away of rocks due to natural elements( wind, water etc.)
So for example the grand canyon. It was formed over years by a river that washed against the rocks causing small parts of the rock to fall off or to wither away. So because of erosion a large rock could become significantly smaller over many years.

Which two plants produce seeds in the same way?
Cypress tree and a rose bush
Marigold and a daisy
Orange tree and a pine tree
Pine tree and a coconut tree
Marigold and a daisy produce seeds in the same way. So, the correct option is B.
What is Flowering plant?Flowering plants produce seeds in different ways, even though the seeds are what are known as fertilized ovules. Some flowering plants produce seeds singly in each fruit, while some produce their seeds inside pods.
Plants such as hibiscus, dandelion and marigold produce their seeds inside pods. However, plants such as the coconut tree produce a single seed that is usually enclosed in a fruit. Flowering plants such as dandelions and coconut trees do not produce seeds in the same way. Flowering plants such as marigolds and daisies produce seeds in this way.
Thus, Marigold and a daisy produce seeds in the same way. So, the correct option is B.
