Organisms are constantly interacting with their environment. Sometimes this interaction has a positive effect on the environment, other times a negative impact. Beetles in the forest infest and eat limbs of trees that have fallen to the forest floor. The best way to describe the beetles impact is to say that A) they are having a neutral impact on the environment by acting as decomposers.

B) they are having a positive impact on the environment by acting as decomposers.

C) they are having a negative impact on the environment by acting as decomposers.

D) they are having a predatory impact on the environment by acting as decomposers.

Answers

Answer 1
Answer:

The correct answer is option B) i.e. they are having a positive impact on the environment by acting as decomposers.

By acting as decomposers beetles are helping in recycling of nutrients between biotic (organisms) and abiotic factors (enviroment). So, it may be considered as positive impact on the environment. Decomposers play a very important role in food chains and food webs. They breakdown biomolecules and liberate the micronutrients and micronutrients as inorganic molecules back to the environment. These inorganic molecules are used by plants once again  to synthesize biomolecules. This is how nutrient cycle operates with the help of decomposers. For example, protein molecules of dead and decaying matter are broken down by decomposers to liberate nitrogen gas to the environment which is utilized by leguminous plants to make protein molecules again.

A parallel DC circuit has a total current of 4 Amperes and a resistance of .5 Ohms. If the current is doubled, and the resistance is halved, how many times more is the new power compared to the old power?

Answers

The answer is 2 times.

In parallel DC circuit the power (P) can be calculated by using the values of total current (I) and resistance (R):
P = I²R

The old power is:
Po = Io² x Ro
Io = 4 A
Ro = 0.5 ohms (Ω)
So,Po = 4² A x 0.5 Ω = 8 W

The new power is:
Pn = In² x Rn
In = 4 A x 2 = 8 A
Rn = 0.5 Ω ÷ 2 = 0.25 Ω
So, Po = 8² A x 0.25 Ω = 16 W

Pn ÷ Po = 16 W ÷ 8 W = 2
Thus, the new power is 2 x higher than the old power.

If a personality survey with high internal consistency includes two different questions related to the personality dimension of agreeableness, then which of the following is true?A.It is impossible to predict how people will answer the second question based on how they answered the first question.

B.If people give an extreme answer to the first question, they will tend to give the opposite extreme answer to the second question.


C.People will tend to give dissimilar answers to both questions.

D.People will tend to give similar answers to both questions.

E.If people give a moderate answer to the first question, they will tend to give an extreme answer to the second question.

Answers

If a personality survey is conducted we can see that people will give two dissimilar answers.

Explanation:

If a survey based on personality is conducted and the people are asked two question which are different in nature. We can see that people answering both the question will have dissimilar answer because according to the personality of people two different question cannot have a same answer , they must be different , that is why there is a tendency to get two different answer from the survey.
