Human activities have altered various natural environments around the planet. Various lands are now fields where only one farm crop is cultivated, is an example of monoculture farming.
An agricultural method of growing or producing a single plant, crop, or a livestock species, breed, or a variety in a field of the farming system at a time is known as a monoculture. Hence, the correct answer is option D, that is, monoculture.
Ricin comes under the category of functionally related toxins, in a combination known as RIPs (ribosome inactivating proteins). This disables ribosomes and stops the process of protein synthesis.
They directly associate with and inactivate the ribosomes or modify the factors taking part in the process of translation, generally the elongation step. These proteins bring about depurination of adenine at position 4324 in the 28 S rRNA.
This further inhibits the generation of a critical-stem-loop configuration to which the elongation factor is considered to combine at the time of the translocation step of translation. The ultimate outcome of this activity is the complete inhibition of cellular translation.
When the patient with emphysema was
selected lung values changed (from those of the normal patient) in the
spirogram are:
ERV, IRV, RV, FVC, FEV1, FEV1 %
<span>The reason behind the changes of these values are due to the loss or inability of electric recoil. A spirogram (graph
like structure obtained by the respiratory movements) is measured by
spirometer.</span>
