In higher doses, micronutrients become toxic. Mineral ion concentration in the tissues which reduces dry weight of tissues by 10% is called toxic concentration. Critical toxic concentration is different for different micronutrients as well as different plants. For example, Mn2+ is toxic beyond 600μg g−1 for soybean and beyond 5300μg g−1 for sunflower. Toxic effects may be due to an excess of the micronutrient or its interference in the absorption and functioning of other nutrients.

Explanation:

The correct answer is option B, toxic concentration.

Mineral ion concentration in tissues that reduces the dry weight of tissues by about 10% is considered as a toxic concentration. This means that when the concentration of mineral ions in tissues exceeds a certain level, it can have detrimental effects on the tissues and their function. Here's an explanation of why toxic concentration is the correct answer:

Effects of Mineral Ions:
Mineral ions play important roles in various physiological processes in organisms. They are involved in enzyme activation, osmoregulation, pH balance, and many other functions. However, excessive accumulation of mineral ions can disrupt these processes and lead to toxicity.

Dry Weight of Tissues:
Dry weight of tissues refers to the weight of tissues after all the water has been removed. It is a measure of the structural and functional components of the tissues. Any decrease in the dry weight of tissues indicates a loss of these components, which can impair the normal functioning of the tissues.

10% Reduction in Dry Weight:
When the mineral ion concentration in tissues reaches a toxic level, it can cause damage to the structural integrity of the tissues. This can result in the loss of essential components and a decrease in the dry weight of tissues. A 10% reduction in dry weight is considered significant and indicates a substantial damage to the tissues.

Toxic Concentration:
Therefore, when the mineral ion concentration in tissues reaches a level that causes a 10% reduction in dry weight, it is considered a toxic concentration. This indicates that the concentration of mineral ions has surpassed the threshold at which it can cause harm to the tissues. It is important to note that the toxic concentration may vary for different mineral ions and different tissues.

Conclusion:
In summary, mineral ion concentration in tissues that reduces the dry weight of tissues by about 10% is considered a toxic concentration. Excessive accumulation of mineral ions can disrupt the normal functioning of tissues and lead to structural damage. It is important to maintain a balance in mineral ion concentration to ensure optimal tissue health.

Read the passage given below and answer the following questions:The rate of a reaction, which may also be called its velocity or speed, can be defined with relation to the concentration of any of the reacting substances, or to that of any product of the reaction. If the species chosen is a reactant which has a concentration c at time t the rate is - dc/dt, while the rate with reference to a product having a concentration x at time t is dx/dt. Any concentration units may be used for expressing the rate; thus, if moles per liter are employed for concentration and seconds for the time, the units for the rate are moles litre–1sec–1. For gas reactions pressure units are sometimes used in place of concentrations, so that legitimate units for the rate would be (mm. Hg) sec–1 and atm. sec–1 The order of a reaction concerns the dependence of the rate upon the concentrations of reacting substances; thus, if the rate is found experimentally to be proportional to the ath power of the concentration of one of the reactants A, to the both power of the concentration of a second reactant B, and so forth, via., rate = k CAα CAβ the over-all order of the reaction is simply n = α + β + ----- (2) Such a reaction is said to be of the αth order with respect to the substance A, the βth order with respect to B.In the following questions, a statement of Assertion followed by a statement of Reason is given. Choose the correct answer out of the following choices on the basis of the above passage.Assertion: Rate of reaction is a measure of change in concentration of reactant with respect to time.Reason: Rate of reaction is a measure of change in concentration of product with respect to time.
