An electrochemical cell that produces electricity from a spontaneous oxidation-reduction reaction

Explanation:

Galvanic cell is a device which is used for the conversion of the chemical energy produced in a redox reaction into the electrical energy.

Galvanic cell consists of two half cells known as anode and cathode. Oxidation takes place at anode and reduction takes place at cathode. The two half cells are connected by a salt bridge which contains an electrolyte which maintains the electrical neutrality.

Answer: The corn plants were damaged by the herbicide.

Explanation

Depending upon the plant affected and the herbicide used, effects of herbicide damage differ. Popular signs include flattened stems or twisting or corkscrewing. Leaves can have shapes, sizes or textures that are irregular. Moreover, yellow or reddened leaves or leaf veins may. This usually leads to loss in crops as noticed from the maize plantation where more than half was lost.

The correct answer is option B. Genotype AA, phenotype-Unaffected.

The cystic fibrosis is a condition caused by the inheritance of the two recessive allele, It is an autosomal recessive disease.

In the given case, the parents are carriers, and the carriers are always heterozygotes. Hence, the phenotype of the both parent should be Aa. A possible cross of the parents is shown in the figure below.

In case, the progeny have a single dominant trait, the child would not be affected, but will be a carrier and can pass the disease to offspring. In case, the child inherit both the dominant allele (homozygous dominant) from the parents, then he/she would be unaffected. In case, the phenotype of the child is homozygous recessive then it would be affected.
