How do farmers contribute to water pollution?A. by dumping garbage into the water
B. by fertilizing their crops with nitrogen compounds
C. by fertilizing with sulfur dioxide
D. by not using fertilizers

Answers

Answer 1
Answer: The best answer is B. Farmers contribute to water pollution by fertilizing their crops with nitrogen compounds. Fertilizers have high contents of nutrients which includes compounds with nitrogen. This may contribute to water pollution when farmers overfertilize their crops which some of the fertilizers run off to bodies of water and may cause eutrophication.

Is human self-interest the driving force behind all environmental problems?Claim:

Evidence:

Reasoning:

Answers

Answer:

Claim: Yes, it is true that human self-interest is the driving force behind all environmental problems.

Evidence:  The Increasing rate of global warming is the best evidence for the claim.

Reasoning: This is so because of human self-interest such as buying a car, burning of fossil fuels in industries, use of plastic, cutting trees, and hunting or poaching result into all environmental problems such as air pollution, deforestation, and endangered wildlife which leads to global warming.

In human DNA, adenine (A) makes up approximately 30.9% of the bases, andguanine (G) makes up approximately 19.9% of the bases; therefore the percentage thymine (T) and cytosine (C) are
(A) 19.8% T and 19.8% C.
(B) 19.8% T and 29.4% C.
(C) 29.4% T and 19.8% C.
(D) 29.8% T and 29.8% C.
(E) 19.9% T and 30.9% C.
Can you please explain with some details?

Answers

In human DNA, there are nitrogenous base pairings- A, T C and G. A pairs with T and C pairs with G. Because they're a pair, the ratio of A:T and C:G should be as close to 1:1 as possible. Since A makes up approx 30.9%, T should be either C or D. As G makes up approx 19.9%, we can rule out option D, therefore the answer is C! Hope this helps (:

Why are annual temperature ranges in the Southern Hemisphere generally smaller than those in the Northern Hemisphere?

Answers

Annual temperature ranges in the Southern Hemisphere generally smaller than those in the Northern Hemisphere because there is a higher rate of the water surface in the Southern Hemisphere.

Water is a prominent absorber of radiation and slower radiator of heat than land Environments in the southerly region which overall tend to be lightly moderate than those in the northerly region. This is because the southerly hemisphere has significantly more beach and less land. Water warms up and freezes down more slowly than land. The southerly hemisphere is also significantly less contaminated than the northerly hemisphere because of lower population densities,  lower levels of industrialization, and smaller land sizes.

Why are Annual temp ranges in the southern hemisphere generally smaller than those in the northern hemisphere? Answer:there is more water
