Which of the following factors affect the productivity of a forest?. A) soil fertility B) water supply C) human activities D) local climate E) all of the above​

Answers

Answer 1

Answer:

E. all of the above

Explanation:

The productivity of a forest is affected and defined by numerous factors. The soil fertility provides the nutrients for the growth of the plants, so the more fertile the soil is the more vegetation there will be, and vice versa. The water supply defines the type of vegetation in the forests, as well as how much that vegetation will produce. The higher amounts of water result in high productivity, while the smaller amounts of water in lower productivity. The climate is always a very important factor, as it can either have negative influence on the forest productivity if it is too harsh or be the basis for high productivity if it is more moderate. The human activities are the newest factor that influences the forest productivity. The humans, with their activities, are more often than not a serious threat to the forests, as most commonly it ends up with destruction of the forest.

I am so confused please help asap! (calc, integrals) please explain as well

Answers

Answer: A.) 8

Explanation:

Use u-substitution.

(1) Let u=x^3

By the power rule, du/dx=3x^2

Multiplying by dx and dividing by three, we have du/3=x^2dx

To find the new lower bound of integration, plug the old bound, -3, for x in equation (1). We get u=(-3)^3= -27

Similarly, when the upper bound 3 is plugged in, u=27

Now, replacing f(x^3) with f(u) and x^2dx with du/3:

[tex]\int\limits^{3}_{-3} {x^2f(x^3)} \, dx= \int\limits^{27}_{-27} \frac{f(u)}3 \, du \\=\frac{1}3\left[\int\limits^{0}_{-27} {f(u)} \, du+\int\limits^{27}_{0} {f(u)} \, du \right] (2)\\Observe:\int\limits^{0}_{-27} {f(u)} \, du=\int\limits^{27}_{0} {f(u)} du\; \text{ because f(x) is an even function}\\\text{Substitute the left hand side integral for the RHS in equation (2):}\\=\frac{1}3\left[2\int\limits^{27}_0 {f(u)} du\right]\\=\frac{1}3 (2)(12)=8[/tex]

since the value of the first integral of the question = 12, which is given. Although the variable is different than the given (u instead of x), it's still the same integral

B. GDP per Capital factors population into the formula to offset countries with high GDPs and high populations.
O C. GDP per capital is not an accurate measure of economic strength since it doesn't take into account the system of government.
D. GDP per Capital take sinto account economic systems into the equation while GDP does not.

Answers

Answer:

The correct answer is B. GDP per Capita factors population into the formula to offset countries with high GDPs and high populations.

Explanation:

The GDP per capita is a macroeconomic indicator by which the total production of goods and services of a country is measured, and this total number is divided by the number of inhabitants of that nation. Thus, the average number of production that each inhabitant generates per year within the country is obtained. In this way, a real knowledge of the country's economic capacity can be taken, depending on whether economic production is equated with the nation's demographic component.

(d) Future achievements cannot be guaranteed.

(b) Large issues may be tackled in small stages.

Explanation:

Asagai's remark to Beneatha indicates that he believes that the current focus should be on achieving African independence rather on than what will happen after it is achieved; the first must be accomplished before the second can be addressed.

Brainlist Pls!

Understand the historical concept of the movie Raison in the Sun, it is found that the correct option is given by:

(b) Large issues may be tackled in small stages.

---------------------------------

This question is based on the movie Raison in the Sun, which is based on Black families experiences in south Chicago, after the death of the father.Two of the characters are Asagai and Beneatha.The passage relative to this question is close to the end of the movie, as they were talking about the end of Colonialism and Independence of African Countries(the movie is from 1959, in a time where many African countries were becoming independent).

Beneatha's remark, to which Asagai responds, is:

"A Independence and then what? What about all the crooks and thieves and just plain idiots  who will come into power and steal and plunder the same as before only now they will be black and do  it in the name of the new Independence WHAT ABOUT THEM?!"

Asagai's remark is that corruption will be a worry after the countries become independent, arguing that first the countries must focus on becoming Independent, and then worrying about future problems, that is, first focusing on the step at hand, stating that a large issue is resolved step by step. Thus, the correct option is given by:

(b) Large issues may be tackled in small stages.

If sales of a new kind of hydrogen car really take off in test markets where it is introduced, what macroeconomic
effects could that have? (Select all that apply.)
large-scale investment in hydrogen car infrastructure
larger number of jobs related to hydrogen car service and fueling in those test markets
increased funding for research and development into advancing hydrogen car technology
Increased focus on reducing environmental impact of commercial construction

Answers

Answer:

large-scale investment in hydrogen car infrastructure  increased funding for research and development into advancing hydrogen car technology

Explanation:

If test markets show that hydrogen cars can be successful, the market will try to take advantage of that and that would include investing heavily into the production of hydrogen cars.

There will also be an increase in the funding for research in hydrogen cars because investors would like to find a way to have an edge over competitors seeing as hydrogen cars are about to increase in production.

Answer:

There are times when memory is very important. Imagine, for example, seeing a stranger for less than a minute as he committed a robbery. On average and in good circumstances, Smith said the witness would accurately pick the suspect from a lineup about 70 percent of the time. Other details may be less accurate. But whether or not you ever actually discover any small or large changes that have occurred, it's unlikely that your treasured memory is 100% accurate. Remembering is an act of storytelling, after all. And our memories are only ever as reliable as the most recent story we told ourselves

M2E4(g) can be synthesized from M2E(g) and E2(g) at 200℃ as shown below. 2 M2E(g) + 3 E2(g) ⇌ 2 M2E4(g) ∆H < 0 Which of the following changes would result in more M2E(g) in the mixture after equilibrium is re-established?​

Answers

Answer:

See explanation

Explanation:

Now, let us consider the equation;

2 M2E(g) + 3 E2(g) ⇌ 2 M2E4(g) ∆H < 0

This means that the reaction is exothermic. The enthalpy change is negative (less than zero). An exothermic reaction is made to proceed in the forward reaction when the temperature is decreased. Hence increase in temperature leads to the equilibrium position shifting to the left (more  M2E(g)) produced.

Also, when the pressure is decreased, the equilibrium position moves towards the left more  (more  M2E(g)) produced.

A: Providing research data on legal cases to lawmakers

B: Joining with other interest groups in a lobbying alliance

C: Presenting arguments as a "friend of the court" or amicus brief in a lawsuit

D: Sending out voting scorecards to inform members of a politician's legislative record

Answers

Answer:

C: Presenting arguments as a "friend of the court" brief in a lawsuit.

Explanation:

An interest group can be defined as a group of people sharing common aims, ideas and concerns, which seeks to influence government or a public policy.

This ultimately implies that, the interest groups consists of individuals who are only concerned about influencing public policy of the government on the basis of a particular common aim and interest.

The public action committee is an example of an interest group. In the United States of America, the public action committee was formed from the labor movement in July 1943 after the U.S. Congress prohibited unions from giving direct support and contributions to political candidates. Thus, public action committees are created by interest groups primarily to influence elections by raising and distributing campaign funds to political candidates.

Other examples of interest groups are labor groups, environmental interest groups, animal rights groups, etc.

Furthermore, an example of the use of litigation by an interest group is presenting arguments as a "friend of the court" brief in a lawsuit because the testimonies (arguments) are done with some level of bias with respect to achieving a favorable judgement from the court.
