Answer:

Apply the principle of parsimony

Explanation:

A cladogram is used to show or illustrate hypothetical speciation and relationships between species. They are commonly used to classify animals.

The principle of parsimony argues that the simplest of competing explanations is most likely to be correct.  

In order to construct a cladogram that best reflects the evolutionary relationship of a group of species. Application of the principle of parsimony  will help in deciding which tree is most likely to have occurred based on the fewest character state changes.

Answer:

Hardy-Weinberg equilibrium AND IF you assume that red hair is a simple recessive trait, then

q^2 = 0.12

q = 0.35 and p = 0.65

p^2 would equal proportion of population that is homozygous = 0.42, so 42% of the population is homozygous for non-red hair.

8-4 Discounting the Transverse Carrier Model. At one time, membrane biologists thought that transport proteins might act by bind
Natasha_Volkova [10]

Answer:

The two main reasons are nonpolar core of the bilayer and the active transport.

Explanation:

The membrane is structured to have two outer layers that are polar and an inner layer that is nonpolar.

If a membrane protein is exposed to the solvent, i<em>t will also have a polar side. It would be very difficult for the polar face of the membrane to move through the nonpolar core of the bilayer.</em> Therefore, this model is not feasible.

One major form of transport, active transport, moves solutes up the concentration gradient. <em>The binding of a solute and then release on another side of the membrane would only work for facilitated diffusion because it would cause a net movement of solutes down the concentration gradient.</em> It is unclear how energy could be expended to drive this process in the transverse carrier model.<em> Therefore, the transverse carrier model does not explain active transport.</em>

Bengal Tigers (Panthera tigris tigris) have coat colors that are either golden (the dominant trait) or white. In examining a pop
Hoochie [10]

Answer:

5%

Explanation:

Frequency of white tigers = 4%

population of tigers = 200

number of heterozygotes = 10

<u>Determine the actual genotype frequency of Heterozygotes </u>

frequency of heterozygotes = Number of heterozygotes / population

= ( 10 / 200 ) * 100

= 0.05 * 100 = 5%
