Answer:

Option (2).

Explanation:

Enzymes are made of proteins that have the specific amino acid sequences. Enzymes have well determined 3D shape and work in their specific shape and at specific physical and chemical condition.

Enzymes may acts as catalyst that can increase the rate of the bio chemical reaction. Each enzyme is specific for one reaction and lowers the activation energy of the reaction. Enzymes increases the effective collision between the substrate molecule and increases reaction rate.

Thus, the correct answer is option (2).

Rina8888 [55]

The question is incomplete. The complete question is:

Question: A gene for corn has two alleles, one for yellow kernels and one for white kernels. Cross pollination of yellow corn and white corn results in ears of corn that have an approximately even mix of yellow and white kernels. Which term best describes the relationship between the two alleles?

a) Incomplete dominance

b) Genetic recombination

c) Chimerism

d) Codominance

Answer:

d) codominance

Explanation:

Codominance is a pattern of inheritance when none of the alleles of a gene is able to mask the expression of the other allele of the same gene. When the two alleles are present together in a heterozygous genotype, both are expressed and the phenotype of the heterozygote is different from both the pure breeding parents. In the given example, cross-pollination of yellow corn and white corn results in the ears of corn that have an approximately even mix of yellow and white kernels. This means that the heterozygote expresses both the allele for the corn color. Therefore, it represents codominance.

What are some ways to prevent wind erosion in a dry, sandy area
Kitty [74]
Preventing wind erosion in a dry, sandy area is feasible through any of the following land-use practices:

a. Tillage - creates soil roughness by making furrows and ridges that are perpendicular to the direction of the wind. 
b. Crop rotation - rotations of legumes followed by shrubs followed by trees then back to legumes work best.
c. Intercropping - is the most widely used particularly in countries with desert areas. One of the most popularly used is oasis agriculture that makes use of about 3 layers of vegetation.
