8. Two rabbits are bred together. One is heterozygous for agouti coat
dusya [7]

Answer:

- Parental cross = Cch  x chch  

- F1 = 1/2 Cch (agouti coat); 1/2 chch (albino coat) >> 1:1 phenotypic ratio

Punnett  square:  

          ch         ch

C       Cch       Cch

ch    chch      chch

 

Explanation:

A heterozygous individual is an individual who has two different gene variants (i.e., alleles) at a particular <em>locus</em>. In this case, individuals having the "agouti coat" trait are heterozygous carrying both 'C' and 'ch' alleles. On the other hand, a homo-zygous individual has the same allele at a given <em>locus</em> (here, the 'chch' genotype associated with the albino phenotype). Therefore, as observed in the Punnett Square above, when a heterozygous parent is crossed with a homo-zygous recessive parent for a single gene, alleles segregate in the gametes of both parents so an expected 1:1 phenotypic ratio will be observed.

blagie [28]

Answer:

CGTCATC

Explanation:

In a DNA double helix, the complementary bases of two strands of DNA are paired by hydrogen bonds. Adenine of one DNA strand is paired with the thymine of the other strand. Similarly, the guanine of one DNA strand is paired with the cytosine of the other DNA strand. If a portion of one of the two strands of a DNA molecule has the sequence GCAGTAG. The sequence of the other strand would be as following:

One DNA strand: GCAGTAG

Other DNA strand: CGTCATC

​If Clark had no ions in his nervous system, ____. ​his action potentials would be faster ​his action potentials would be slower
telo118 [61]

Answer:

If Clark had no ions in his nervous system, he would not be able to generate an action potentials.

Explanation:

An action potential occurs when a stimulus causes sodium channels to open in a neuron. Sodium floods in, making the inside of the cell more negative and the outside more positive. This is known as depolarization. Then, the Potassium channels open to allow Potassium out (Repolarization). A few too many K+ ions will leave the cell (Hyperpolarization), and finally, the Sodium-Potassium pump will bring the cell back to resting potential.

As you can see, the Sodium and Potassium ions are <em>essential</em> to action potentials in the nervous system. If Clark had no ions in his system, he would not be able to send any action potentials at all.
