B.) Denitrification is the answer
L-cysteine and L-valine
Penicillin is a secondary metabolite commonly found in the filamentous
fungi and they are synthesized from the amino acid precursors L-cysteine, L-valine and l-α-aminoadipic
acid. β-lactam antibiotic penicillin are antibiotics commonly used for the
treatment or therapy of infectious diseases.
Am certain that a human gamete produced by such a nodisjunction could have a chromosome number of 43. Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division. There are three forms of nondisjunction: Failure of a pair of homologous chromosomes to separate during meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis.
<span>The answer is Metamorphic rocks.
Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock (protolith) is subjected to heat and pressure causing profound physical or chemical change. The protolith may be a sedimentary, an igneous, or even an existing type of metamorphic rock.</span>
Answer:
Deserts
Explanation:
A desert is an arid region without no rainfall and land cover in form of soil or vegetation.
Erosion is the wearing or the removal of earth materials.
In a desert region where the surface is exposed and annual rainfall or any other means of precipation is low experiences massive wind erosion. It is common to find loose sand materials and highly friable clayey particles in a desert. Running water and glalciers would have little to no impact here.
