Forests dominated by gymnosperms tend to have mechanisms to allow it to regenerate after a fire. As a consequence this type of forest ______________.
a. dominate areas where the U.S Forest Service does not put out fires.
b. only lives 20-30 years
c. is dominated by trees of a single age
d. has no overstory species
Answer:
Forests dominated by gymnosperms tend to have mechanisms to allow it to regenerate after a fire. As a consequence this type of forest is dominated by trees of single age .
Explanation:
It is possible to conclude the question given above in many ways. After a forest fire in a specific forest patch occurs, the impacts are determined by the severity of the fire and the type of forest in which the occurrence occurs. Usually, the dramatic effect on the trees and plants that can be seen in that region can be seen after such an occurrence has occurred. In certain situations, the situation can also worsen, leading to the destruction of the entire cover, if the circumstances favor the propagation of fires. In such cases, the removal of the prevailing structure can lead to the formation of a new forest structure through a mechanism called 'succession,' in which there is a sequence of progression in a biologically acceptable manner through the growth of different plant species. Simply put, the new plants will attempt to adapt or acclimatize to the conditions introduced after forest fire in such a way that this will later provide the route for the growth of plants and trees that can not easily accommodate in the harsh conditions. Therefore, instead of the forest surviving for a short period of time following a forest fire occurrence, there would be changes in the nature of the forest. This suggests that option 'B' is not the response that is most suitable.Choice 'A' appears to be logically inaccurate, taking into account that if they are of high intensity, fires may be uncontrollable. In addition, there is no clear mention of the fire's region of origin and which trees are most affected. Typically, gymnosperms illustrate a simple process in which they can not limit their destruction from the flames, while they can provide a way for their progeny to initiate next generation development in the form of seed. This occurs in the case of Gymnosperms in which, under ordinary conditions, the seeds of the plants are enclosed within a cone that is restricted from germinating. Although the fires pave the way for the seeds to germinate under certain fire conditions, which in turn leads to the emergence of the next generation of gymnosperms, and several studies indicate that these newly introduced seeds would have the same age as choice 'C' indicated. But, as this is not under the jurisdiction of the US Forest Service, legally, option 'A' tends to be wrong. At the same time, it can be seen that forest fires are not consistent in their coverage in certain cases, and thus the chances of dispersal and germination tend to be not even and thus choice 'C' can be reported to be either correct or incorrect in all possible ways.But, first, it is important to know what an overstory is for the option 'D'. A forest consists of trees of all sizes, from the smallest to the tallest pine trees. The uppermost element that is directly in contact with the light from the sun is the overstory. The manner in which the degree of overstory damage occurs depends on the moisture content of the trees and the other associated conditions around the trees. Taking this into account, a forest fire may either lead to the loss of an entire overstory or can have impacts that are confined to plants and trees at the ground level. So, even the 'D' option can be right or inappropriate. But, therefore, choice 'C' should be the most suitable response, taking into account that most studies indicate growth of single-age trees due to germination mediated in the presence of fire. This seems to be scientifically right for a small patch where there was also fire-mediated damage. Accordingly, the most suitable response should be option 'C'.Hence , the correct option is C.

Permits in the cap and dividend policy are issued for _______ production. a. carbon dioxide b. timber c. water pollution d. plastic
Answer:
the answer is A.. I think
Permits in the cap and dividend policy are issued for carbon dioxide production. Therefore, option (A) is correct.
What is The cap and dividend policy?The cap and dividend policy is one potential approach to lowering carbon emissions and slowing the progression of climate change. The way it works is by first establishing a limit on the total amount of carbon emissions that are permissible within a given time period, and then handing out permits to businesses in proportion to the amount of emissions that they are responsible for producing.
If a company emits fewer greenhouse gases than their allotted amount, they have the option of selling their unused permits to businesses that have a demand for more. This results in the creation of a revenue stream that can be distributed to individuals in the form of a dividend, as well as a financial incentive for businesses to reduce the amount of carbon emissions they produce.

If a plant does need to use a molecule of glucose from its starch reserves it will use what type of reaction to detach the molecules of glucose
A) Hydrolysis
B) Condensation
C)Dehydration synthesis
D)Covalent bonds
Answer:
c it is c
Explanation:
The plant uses the dehydration synthesis reaction to detach a molecule of glucose that it doesn't need. So the correct option is C.
What is the dehydration synthesis reaction?Dehydration synthesis reactions are combination reactions or synthesis reactions. These either happen between the same monomers or between the different monomer units. They always result in the elimination of water molecules.
These are a type of condensation reaction where the water molecules are eliminated and two other molecules are added.
Each step of the dehydration reaction happens with the elimination of water molecules and thus this reaction is called a dehydration reaction. It also results in the formation of a new substance and thus it is called a dehydration synthesis reaction.
Therefore many biochemical reactions occur through this mechanism of dehydration. For example, the formation of peptides from amino acids is an example of a dehydration synthesis reaction. It is the process of the formation of peptide bonds. This happens between two amino acid molecules.
Therefore the correct option is C.

why isn’t ground water found in all of earths layers
Answer: bc gravity pulls water and everything else toward the center of the Earth. That means that water on the surface will try to seep into the ground below it. The rock below the Earth's surface is the bedrock but as you get closer to the core it gets hotter also each layer besides the ground layer// our surface is cover so water wouldnt
be able to substain under the earths layers
Explanation: The rock below the Earth's surface is the bedrock. If all bedrock consisted of a dense material like solid granite, then even gravity would have a hard time pulling water downward. But Earth's bedrock consists of many types of rock, such as sandstone, granite, and limestone. Bedrocks have varying amounts of void spaces in them where groundwater accumulates. Bedrock can also become broken and fractured, creating spaces that can fill with water. And some bedrock, such as limestone, are dissolved by water -- which results in large cavities that fill with water
Visualize it this way: get two sponges and lay one on top of the other. Pour water (precipitation) on top and it will seep through the top sponge downward into the bottom sponge. If you stopped adding water, the top sponge would dry up and, as the water dripped out of the bottom sponge, it would dry up too. Now, put a piece of plastic wrap between the sponges, creating your "confining layer" (making the bottom sponge an impermeable rock layer that is too dense to allow water to flow through it). Now when you pour water on the top sponge, the water will seep downward until it hits the plastic wrap. The top sponge will become saturated, and when the water hits the plastic wrap it won't be able to seep into the second sponge. Instead, it will start flowing sideways and come out at the edges of the sponge (horizontal flow of groundwater). This happens in the earth all the time -- and it is an important part of the water cycle.
