Is iron a macronutrient, a micronutrient, or neither? Explain what its primary function is in plant growth and development. (a) Describe nitrogen fixation. (b) Why is it important to agriculture? Explain how human activities can cause an imbalance in biogeochemical ...
Electrospray settings were the following: the cone voltage was 2.5 kV and 3.2 kV; the collision energy was 6.0 and 4.0 eV; and the temperature of the ion source and desolvation nitrogen gas temperature were 120 °C and 400 °C for positive and negative ionization mode, ...
Nitrogen is one of the most abundant gases in the atmosphere and is essential because of its life-sustaining properties. However, the form of nitrogen in the atmosphere is unstable and cannot be used by organisms, especially plants for their processes. To convert it...
In particular there is a growing body of literature investigating how individuals' SWB relates to the quality of their environments (EQ). Due to the non-market nature of many elements of EQ, standard measures may provide limited insight (Frey and Stutzer, 2002), and can even paradoxically be...
In general, trait imputation has been shown to decrease bias when compared to removing species with missing trait data (Penone et al. 2014). Community-Weighted Means (CWMs) and Functional Diversity (FD) indices To understand important aspects of the functional community structure, we combined ...
Life in the clouds of Venus, if present in sufficiently high abundance, must be affecting the atmospheric chemistry. It has been proposed that abundant Venusian life could obtain energy from its environment using three possible sulfur energy-metabolisms.
in which traits are beneficial to one sex but harmful to another4,5,6. It is important to distinguish between sexual dimorphic traits caused by primary genetic changes that lead to the loss of male or female functions and secondary changes in adaptive states. As a direct consequence of the ...
Pneumatics is the science and technology of pressurized air—using piped, compressed air (or a similar gas, such as nitrogen) to transmit force and energy.So a pneumatic drill (or jackhammer) can blast the pavement apart with a metal chisel pumped up and down by compressed air feeding in ...
What is the role of water in cycles of matter? How does it affect it and how important is it? Explain why the cohesive nature of water relates to its evaporation. What effect does Green Tea have on Urine pH and what importance does this have to osmoregulation and the world at large?
In humans and mammals, the maximum amount of nitrogen is excreted in the form of urea. The urea is synthesized after a series of reactions in the liver cells. Ammonia refers to a toxic product produced during the metabolism of nitrogen, which has to be excreted out from the body in a ...
