1. Dorsal column-medial lemniscal pathways - It would prevent the body from receiving stimuli related to pain and temperature: Corresponds to sensory pathways related to an organism's proprioceptive awareness. It is through these pathways that sensory stimuli and electrical impulses are transmitted from the body to the brain resulting in the display of quick and efficient responses. If cut, the individual would not be successful in receiving stimuli related to pain and temperature.

2. Anterolateral pathways - It would also prevent the sensation of pain and temperature, in addition to hindering the perception of touch and pressure: Located in the anterior part of the lateral column, this pathway is responsible for the transmission of nociceptive information, generally related to pain awareness. and temperature. Its cut would not only make it difficult to transmit these factors, but it would also make it difficult to transmit extroceptive information to the cortex.

3. Spinocerebellar pathways - would hinder information about the position of body members and joints: This pathway is located between the spinal cord and the ipsilaterally in the cerebellum. It consists of thousands of axonal fibers whose main function is to transmit information about the location of the body members, arms and legs, in addition to their joints. Its cut would make it difficult, or even prevent this information from being captured by the brain.

4. Pyramidal pathways - It would prevent the union of the cerebral cortex to the motor neurons of the spinal cord: It is formed by several axons that extend between the cerebral cortex and the spinal cord passing motor information that would be interrupted if the path was cut.

Where is the majority of negative charge on the water molecule?
rusak2 [61]
 A water molecule (H2O) will have a slightly positive side, and a slightly negative side. The oxygen side of water is the one that is negative, while hydrogen side tends to be more positive. When a molecule has a half negative and half positive side like water does, it is called a polar molecule. :D

What is the biological significance of genetic diversity between populations? What is the biological significance of genetic div
mrs_skeptik [129]

Explanation:

<u>A) Genes for traits conferring an advantage to local conditions make microevolution possible.</u>

For example, Galapagos finches show variation in beak sizes and shapes related to their niches and available food source; the finches developed adaptations to their environment. Their specialized beaks allow them to adequately exploit the available resources, by utilizing the more abundant food source.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.  Crossing over, independent assortment, and random fertilization ensure genetic variation.

This variation refers to the genetic characteristics present within a species; they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring an advantage.  

Additionally, natural selection, mutation, genetic drift and gene flow lead to microevolution; over time, this is seen as changes to allelic frequencies within a population
