The ability to identify the specific location of skin touch in two different areas is communicated through sensory pathway .

<h3>What is sensory pathway?</h3>

The cerebral cortex or the cerebellum are the two destinations of the brain, and sensory pathways are the channels by which sensations or impulses travel from sense organs or receptors to the response centers there. While cerebellar impulses are important in coordination functions, cerebral cortex impulses enter through the thalamus and travel to the conscious portion of the brain.

Ascending and descending tracts make up the majority of the sensory pathways.

Ann [662]

Answer:

The correct answer is "short RNA primers; Okazaki fragments".

Explanation:

The missing information of this question is as follows:

"Replication of the lagging strand of dna is accomplished by repeatedly making __________ followed by 1,000-2,000 nucleotide segments called __________"

The correct answer is "short RNA primers; Okazaki fragments".

DNA replication always occurs from 5' to the 3' end, in what is known as the directionality or the end-to-end chemical orientation in molecular biology. This fact makes difficult the synthesis of the lagging strand of DNA. In order to achieve this short RNA primers are bound to segments of DNA (serving as the 5' end available for the DNA polymerase to synthesize), which leads to the discontinuous synthesis of Okazaki fragments that are later linked together by the enzyme DNA ligase.

2. Tim and Stephanie are devastated when the

saul85 [17]

Answer:

Explanation:

<em>Tim and Stephanie are devastated when they find out their newborn son has hemophilia- sex-linked recessive disease. Tim is shocked because he doesn’t have hemophilia, and figured if his son has it he would have gotten it from him. Is Tim correct in his thinking? Explain. Also explain what their genotypes must be in order for neither parents to have the disease but their son does. Create a Punnett square, and indicate the mother's and father's genotype.</em>

<em />

First of all, the thinking of Tim is wrong. Hemophilia is X-linked and a male (XY) child always inherits his X chromosome from his mother. Hence, <u>the newborn son of Tim must have inherited the allele for the disease from Stephanie.</u>

Now, neither Tim nor Stephanie showed any symptom of hemophilia. It could only mean that Tim is totally free of the hemophilic allele while Stephanie is a carrier for it. Because a man has just one X chromosome, he can either be totally free of the abnormality or affected by it, no in-between. A woman has two X chromosomes, hence, she can be totally free, a carrier, or affected for the disease. Assuming the allele for hemophilia to be h, Tim's genotype would, therefore, be $X^HY$ while that of his wife would be $X^HX^h$ .

The Punnet's square analysis of the cross between Tim and Stephanie is indicated in the attached image.
