Answer: Companies are cutting down trees to make space for factories and produce paper products.

Explanation: when people finish using paper products they throw them away and the paper products get burned, and that produces carbon dioxide

Answer:

No.

Explicación:

No, las plantas de semilla no se dividen en dos grupos según el lugar donde se desarrolla la semilla en angiospermas y gimnospermas. Se dividen en dos grupos sobre la base de semillas desnudas y semillas cerradas. En las angiospermas, las plantas son plantas con flores que llevan sus semillas cerradas dentro de los frutos mientras que en cambio, en las gimnospermas son plantas que no producen flores y llevan conos y semillas.

The answer of the question is option (b).

Digestion of dietary fats ocuurs majorly when it reaches to the small intestine.

let's say we were using e for ear length

the genotype would be EE

the phenotype would be short ears

Answer:

Below :D

Explanation:

So basically, this question is asking what will cause a species' population to reach a point where it stops increasing.

Lets think about what can cause a lack of increase?

A decrease can cause this.

Or a slow in the rate of increase.

Now lets look at our selectable answers and see if any of them would fall under these two things.

First up is fewer deaths.

Well, fewer deaths basically means less of a decrease in population.

This is the opposite of decreasing the populatin count, and would instead raise it.

Next we have a limit in food supply.

This would cause a organism to starve and die.

So this would cause a decrease in population count.

So B is one of the answers

Next up is competition with other species.

When two species compete for a sort of resources, one massivly dies out due to outcompetion, and loses the resources needed to survive.

So this would also cause a large decrease in population count.

This makes C one of the answers

Next is increase in birth rates.

This would cause more organisms to be born of a species, basically increasing the population count.

This is the opposite of a decrease in  population.

Next we have competition for space.

This is very similar to answer C, and the outcompeted species dies out due to lack of space.

So E is one of the answers

Now, the next answer seems viable, because major storms can kill off organisms, like hurricanes, earthquakes, and volcanos for instance.

However, as seen in many organisms over history, while these major storms kill of organisms, they can recover.

So although major storms decrease populations, they dont actually limit them.

In the end:

B is correct

C is correct

E is correct

Answer:

Limestone

Explanation:

Limestone is made up of carbonate minerals, such as calcite. The shells and skeletons of ocean organisms are formed of these minerals. When the organisms die, the shells and skeletons settle on the ocean floor as layers of sediment. Over time, the layers become buried, pressed together, and cemented to form limestone.

Some sites are:

Mesopatamia, and Epipalaeolithic,

Answer:

Whales are mammals that need air from the sea's surface to survive. Whales are capable of giving birth to live young. Fish have gills and use them to draw oxygen from the water. The majority of fish lay eggs. Whales and other marine animals with horizontal tail fins, such as dolphins, have vertical tail fins, while fish have vertical tail fins.

Answer:

VENUS

Explanation:

On Venus, one rotation on its axis takes the equivalent of 243 Earth days and the planet's orbit around the Sun takes the equivalent of 225 Earth days.

Answer:

Venus, I think

Explanation:

So outta these three, Venus is the closest to the sun, so the year is the shortest. Venus is also the planet with the longest day averaging at 116d 18h, so I think that's the right one. Sorry if this is wrong

The answer is :

B. Neutron

Answer: Ability to moderate temperature

Explanation: the water is able to moderate temperature to maintain homeostasis. It tries to cool down when it is extremely hot and heat up while we are cold. If water didn’t have this property then we would not be able to live in places like New York or Massachusetts due to the extreme temperatures

Answer: The greenhouse gas emissions from the extraction of bitumen and the use of large quantities of water.

Explanation:

Bitumen is a natural flammable organic matter formed from kerogen in the process of petroleum generation, which is soluble in carbon disulfide. Asphalt and mineral wax are examples of hydrocarbons which are part of bitumen. Conventional oil is extracted by wells while oil sands deposits are extracted using surface mining sectioning techniques, or are flowed to wells by in situ techniques that reduce bitumen viscosity by steam and/or solvents. So, unlike crude oil extracted in oil wells, bitumen requires an open-pit mining operation, in which large tracts are washed with a mixture of water and chemicals to separate the bitumen from a mixture of sand and clay.

Two consequences of this practice are:

A mutation is any change in the sequence of DNA because of any reason such as deletion, insertion, etc. To determine the mutation in a DNA molecule changed the structure of a specific protein scientists should know the normal sequence of bases that code for the protein.

A mutation is a random change in the DNA sequence either due to insertion, deletion, or substitution.

By mutating a gene's code for making a protein, a variant can leads to a protein's improper functioning or to not being produced at all.

Scientists must mandatorily determine the normal base sequence of the protein code before investigating the mutation in the DNA sequence for a particular protein.

Thus, the correct option is A.

Explanation:

Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. This flat upper line on a growth curve is the carrying capacity. The carrying capacity (K) is the maximum population size that can be supported in a particular area without destroying the habitat.
