Rabbit ear size tends to decrease as latitude increases. this is an example of a cline
.
A cline can be described as a change of the biological trait of a species across its geographical range. A cline can be genetic for example, change in the allele frequency, or phenotypic (change in body size). The change can be shown as continuous gradation, or it can be more abrupt from one geographic region to the next.
Answer: p (short hair) = 0.91 and q (long hair) = 0.09
Explanation: In the population, short hair is a feature of domnant allele, because there are more short haired individuals than with long hair. In genetics, p is the frequency for dominant allele and q is for recessive allele.
For this question, short hair is allele L and long hair is allele l
So, the frequency of short hair is p and of long hair is q.
To calculate the frequencies:
Frequency of allele L = (number of copies of allele L in population) / (total number of L/l gene copies in population)
p = 182/200 = 0.91
The same formula goes for the recessive allele, so:
q = 18/200 = 0.09
Thus, the frequencies of hair allele are 0.91 and 0.09 for short and long, respectively.
Water and sodium ions are reabsorbed in the proximal tubule in a relationship that results in a decrease in tubular fluid volume that is isotonic to plasma.
<h3>What do you mean by Proximal tubule?</h3>
A Proximal tubule may be defined as the portion of the nephron that lies in between Bowman's capsule and the loop of Henle.
The major function of the proximal tubule is to reabsorption of sugar, sodium, chloride ions, and water from the glomerular filtrate. It decreases the volume of tubular fluid.
Therefore, water and sodium ions are reabsorbed in the proximal tubule in a relationship that results in a decrease in tubular fluid volume that is isotonic to plasma.

Answer:
algae
Explanation:
<em>If a carbon in a molecule of carbon dioxide from the air is traced into a molecule of glucose inside a fungal cell, the carbon must have gone through an algae in order to get into the fungus.</em>
Fungi generally do not have the ability to fix carbon dioxide through photosynthesis. However, they are able to form a symbiotic relationship with algae through an organism known as lichen.
In lichen, the fungi and the algae enter a mutually beneficial relationship in which the fungi provide moisture and nutrient to the algae and in turn, the algae provide food to the fungi out of the sugar produced from photosynthesis.
<em>Hence, a carbon traced from the air to a fungi most likely passed through an algae as a result of symbiotic relationship between the two organisms.</em>
