List two essential mineral elements. For each, state a function and a deficiency symptom. correct answersNitrogen is an essential mineral element in plants. Deficiency in nitrogen causes reduced growth, woody stems, and purple leaf pigment from anthocyanins. Another nutrient is phosphorus. Phosphorus deficiency causes reduced growth and slender stems, and dark green leaves with necrotic spots. A gardener observes symptoms on their tomato plants of chlorosis in between leaf veins on older leav...

what is an amphibolic pathway ~ both catabolic and anabolic how is the krebs cycle amphibolic ~ the initial steps of the krebs cycle are anabolic because they involve the creation of a six carbon intermediate called citrate from acetyl coA and oxaloacetate. However the following steps are catabolic because they involve the removal of a carbon to yield co2 and other intermediates with 4 or 5 carbons. the final step is the regeneration of acetyl coa by splitting oxaloacetate What is ...
