Answer:

There is inverse relationship between DDT use and bald issue reproduction

Explanation:

Dichlorodiphenyltrichloroethane, is commonly known as DDT, which is a colorless, tasteless, and almost odorless, crystalline chemical, an organochlor. Originally developed as an insecticide, it is famous for its environmental impact. DDT was synthesized first in 1874 by the Austrian chemist Othmar Zeidler. The breeding of bald eagles in northwest Ontario rose from 1.26 offspring per breeding area in 1966 to a low of 0.46 in 1974 and then rose to 1.12 in 1981. The DDE residues in the added eggs showed a significant inverse relationship, confirming the effects of toxin on population-level bald head reproduction and the effectiveness of the DDT ban. The recovery from DDE contamination in the bald eagle appears to be much faster than expected.

Which statement about the light-independent reactions in photosynthesis is true?.
rjkz [21]

Answer:

The correct answer would be They comprise the Calvin cycle.

Calvin cycle refers to the set of chemical reactions taking place in the stroma of the chloroplast in which carbon is fixed into food (glucose). The whole process is divided into three stages namely: fixation, reduction, and regeneration (ribulose bisphosphate or RuBP).

It takes place in light-independent reaction of the the photosynthesis.

It does not require light energy to carry out the reactions however, it depends upon the products of light reaction (ATP and NADPH).

Fixation of one molecule of glucose requires 6 molecules of carbon dioxide, 9 ATP and 6 NADPH.

The fixation of carbon is catalyzed by an enzyme RuBisCO.

Meteorologists take careful measurements of daily minimum temperatures, maximum temperatures, and precipitation (rainfall). The
Vinil7 [7]

Months with higher temperature have more rainfall.

Explanation:

From the presented graph, we can see that all three parameters are following a same trend. When the maximum temperatures increase, the minimum temperatures increase too, and the rainfall increases as well. When the maximum temperatures decrease, the minimum temperatures decrease, and the rainfall decreases too.

There is a simple explanation for the connection of higher temperature and more rainfall in Scotland. Scotland is located on an island, thus it is heavily influenced by the sea. When the temperature is higher, the humidity is higher, and in accordance to that more rainfall occurs. When the temperature is lower, the humidity is lower, so there is less rainfall, or instead of rainfall the precipitation can be manifested as snowfall.
