Answer:

The given case is an illustration of natural selection. Natural selection refers to the phenomenon on the basis of which the organisms that get amended with the environment, seem to thrive and generate more offspring. The theory was first postulated by Charles Darwin and is now considered to be the prime reason, which results in evolution.  

Similarly, in the given question, the insects who could withstand the environment around them continue to reproduce, in comparison to those who could not cope up with the environment, thus, this would be regarded as an illustration of natural selection.

'Natural selection' can be defined as the process of selection of the organisms who are more evolved and better suited for their surroundings and are capable of producing high number of offsprings. Artificial selection can be defined as the selection of the organisms by the humans to selectively breed whether or not they are suited for the changing surroundings or not. Since, the farmer only introduced the pesticide, and the insects evolved and inherited resistance to the pesticide, this is a case of the natural selection.

1. If a red flower (RR) and a white flower (rr) were crossbred, resulting in 100% Rr, what phenotypes would be seen according to
Digiron [165]

Answer: 1) The phenotype of Rr is Pink according to incomplete dominance.

Incomple dominance occurs when none of the alleles is completely dominant over the other, resulting in blending of the phenotype from the parents. When a red (RR) and a white flower (rr) are crossbred, they result in Rr that is a pink phenotype.


2) According to Codominance, the phenotype of Rr is Red and White flower.

Codominance occurs when both the alleles are equally expressed. In this case allele for Red (R) and white (r) phenotype are expressed equally giving Red and White flower.


3) In Codominance, both the alleles are visible in the hybrid and in Incomplete dominance, intermediate (blend of parental) phenotype is visible in the hybrid.

If the left primary sensory cortex were damaged along the longitudinal fissure, a person could have trouble detecting sensation
kobusy [5.1K]

Answer:

right foot

Explanation:

The primary sensory (somatosensory) cortex is a region of the brain that receives nerve signals, which is located in the anterior part of the parietal lobe. The primary sensory cortex processes somatic sensory info from receptors for pain, pressure, touch, and temperature. The primary somatosensory cortex on the left side of the brain coordinates the sensory data of the right side of the body, while the primary somatosensory cortex on the right side of the brain coordinates the sensory data of the left side of the body.
