When corn plants are too tall, they lodge (topple over) prior to harvest. This is bad since the grain is often lost when it cannot be picked up off of the ground by mechanical harvesters. You have a high-yielding strain of corn, but the plants often lodge. You want to estimate broad-sense heritability for % lodging in corn. You start by mating two inbred lines to produce an F1 generation. The F1 was allowed to intermate to produce an F2 generation. The variances for each generation are given below: Variance of inbred line 1 = 311
Variance of inbred line 2 = 333
Variance of F1 = 316
Variance of F2 = 1153
1. What is the phenotypic variance?
2. What is the environmental variance?
3. What is the genetic variance?
4. What is the broad-sense heritability?

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
