A population of grasshoppers in the Kansas prairie has two color phenotypes, green and brown. Typically, the prairie receives adequate water to maintain healthy, green grass. Assume a bird that eats grasshoppers moves into the prairie. How will this affect natural selection of the grasshoppers?

The survival rate of green grasshopper increases and the brown grasshopper decreases

Explanation:

Natural selection is the mechanism which drives the process of the evolution of species.  The natural selection process puts pressure on the species which allows the organism to adapt in the organism and then nature selects the species which are best adapted to the survival.

The adapted trait if increases the survival rate in the environment is passed on to the generation and if not then decreases.

In the given question, when the green grass prairie increases then the green grasshoppers will have an advantage that they can hide themselves and the green color trait increases the survival rate but the brown color increases the chances of predator feeding and is not passed on to the offsprings.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
