Answer:
ecoligical footprint
Explanation:
The ecological footprint is a method that is use to calculate the human demand on natural resources provided by the Global Footprint Network.
It means utilisation of natural resources by humans to sustain or maintaining economy. It monitors this demand through an ecological network of accounts.
Ecological footprint measures how much area of biologically productive water and land, an operation or a population require to produce used resources and absorb the waste it produces, using prevailing technology and resource management practices. So, the lands provided to the humans for farming is an example of Ecological footprint as people utilises lands for sustainabilty and contribute to economy as well.
Hence, the correct option is ecoligical footprint.
The answer is D. lose apical dominance and grow lateral branches
Apical meristem is a meristem tissue found at the branch tips. When it is active, tree grows in height and the lateral branches will not be as dominant. Imagine conifers and their branches. However, when apical meristem is removed, that apical dominance will be lost, and the lateral branches will become more dominant, so the tree will look more branchy.
1 in 12. I dont know the percent though.
The first organisms in the food chain are the producers. These are the plants. Their role is to capture energy from the sun and turn it into chemical energy that is then used by every other organism in the community.
A rapid lateral flow immunoassay is presented that uses carboxyl-modified superparamagnetic nanoparticles as labels that can be quantified by highly sensitive multi-channel electronic readers. The approach is generic in that it is likely to be applicable to numerous small molecules. The method permits both single- and multiplex assays at a point-of-need without sample pretreatment. It is user-friendly and offers attractive characteristics demonstrated here for detection of morphine, fentanyl and methamphetamine in . The competitive immunoassay uses commercially available reagents that do not require special permissions. After migration of sample, the lateral flow test strips are subjected to an alternating magnetic field at two frequencies. The response from the nanolabels is readout at a combinatorial frequency from the entire volume of a porous immunochromatographic membrane by the magnetic particle quantification technique.
application to the determination of drugs of abuse.
Estimating the detection time of a drug in urine is complex because of many different influencing factors and the lack of experimental data. Detection times vary depending on dose and route of administration, metabolism and characteristics of the screening and confirmation assays. Using a cut-off value of 1000 ng/mL, urinary samples can be positive for amphetamine for up to 5 days after intake of the drug.
