Answer

similar characters evolved owing to convergent evolution; similar characters are ancestral

Explanation:

Convergent evolution happens when two organisms belonging to different species, living at different times or different continents but the same biome develop analogous structures hence making them appear similar.  The analogous structures were not present in the known ancestors of both groups.

Therefore convergent evolution is ignored during constructing phylogenies

Also similar characteristics that are ancestral are ignored.

Which part of the nervous system takes the information received from the senses
AURORKA [14]

Answer:

The spinal cord is responsible for carrying information

Explanation:

The spinal cord carries messages to and from the body to the brain, but it is the brain's task to make sense of all the information. Reflexes are action rather than structure, and inter neurons were only discussed in terms of their role in spinal cord reflexes.

What would be the effect on climate in the temperate latitudes if Earth were to slow its rate of rotation from a 24-hour period
grin007 [14]

The correct option is (E) The climate would stay the same. The only change would be longer days and nights.

If Earth were to slow its rate of rotation from a 24-hour period of rotation to a 48 -hour period of rotation, the climate would stay the same. The only change would be longer days and nights.

<h3>How does the rotation of the Earth affect day and night?</h3>
  • Earth rotates on its axis, or turns, once every 24 hours, carrying us all along with it. We experience daylight when we are on the side of the Earth that faces the Sun. We are now on the side of the Earth that faces away from the Sun, and night has fallen.
  • The Earth revolves counterclockwise, and if we were to look down on it from above the north pole, we would notice that day and night move over our planet from east to west.

I understand that the question you are looking for is "What would be the effect on climate in the temperature latitudes if Earth were to slow its rate of rotation from a 24-hour period of rotation to a 48-hour period of rotation?

A) Seasons would be longer and more distinct (colder winters and warmer summers).

B) There would be a smaller range between daytime high and nighttime low temperatures.

C) Large scale weather events such as tornadoes and hurricanes would no longer be a part of regional climates.

D) Winter seasons in both the northern and southern hemispheres would have more abundant and frequent precipitation events.

E) The climate would stay the same. The only change would be longer days and nights.

In trout, Gene A affects body color and yellow color (allele a) is recessive to red. In a particular river system you find that
hjlf

Answer:

The frequency of the dominant A allele is 0,4 or 40%.

Explanation:

In this population, we have:

- "A" red body color Dominant

- "a" yellow doy color Recessive

So, individuals AA and Aa will be red and trouts aa will be yellow.  In this case, 64% of the fish are red, so they are AA or Aa.

If the population is in Hardy-Weinberg equilibrium the following will be true:

p^{2}+2pq+q^{2}=1

Where:

p^{2}=frequency of AA

2pq= frequency of Aa

q^{2}=frequency of aa

It is known that 64% of population is red, in other words:

p^{2}+2pq=0,64

Or AA+Aa=0,64

So, it is possible to find the value of q^{2} (aa):

p^{2}+2pq+q^{2}=1

(0,64)+q^{2}=1

q^{2}=1-0,64q^{2}=0,36

Now, there are two alleles in this population, therefore their frequencies will be:

p+q=1

So, from q^{2} it is possible to find q and p:

q=\sqrt{q^{2} }

q=\sqrt{0,36}

q=0,6

And:

p+q=1\\p=1-q\\p=1-0,6\\p=0,4
