Consider the data on cliff swallow mortality. Why is this an example of directional selection?Overall genetic variation decrease

d.Selection did not occur, because no reproduction occurred (just survival).Individuals with intermediate phenotypes survived best.The average trait value changed in one direction (in this case, larger size).

Answer:

The average trait value changed in one direction.(In this case, larger size)

Explanation:

In evolution a natural selection can be disruptive, directional or stabilizing

In stabilizing no extreme trait is favored hence provides intermediate values .

Disruptive selection both extreme traits are favored over the intermediate trait.

Directional, the enviroment will favor the survival of one trait hence a change in direction either towards the left or the right.

In the case of swallow cliff mortality, selection favored the larger size.

What is the purpose of a wasp
Inessa [10]
In early summer wasps, like bees, pollinate plants and flowers as they feed on nectar. If we were to eradicate all wasps, it would cause more problems than it would solve. So, wasps do serve a purpose, and despite being a problem at certain times of the year, they are a beneficial insect.

When setting up a Sanger sequencing reaction, each reaction should include template DNA, nucleotides, dideoxynucleotides, buffer
kondaur [170]

Answer:

b. Forward or reverse primers

Explanation:

Sanger sequencing is a technique of DNA sequencing based on the extension of DNA fragments with variable sizes terminated with dideoxynucleotides at the 3′ end. This technique was developed by Frederick Sanger in 1977. In Sanger sequencing, a short primer is added in order to bind by complementarity to the target DNA region of interest. Subsequently, a DNA polymerase adds nucleotides (A, T, C and G) in the 5'-3' direction. Finally, the extension of the DNA strand is stopped by adding dideoxynucleotides, which are nucleotide analogs (i.e., modified nucleotides) that act as DNA synthesis terminators.

krok68 [10]

When restraining a horse for a routine veterinary procedure, it's appropriate for the veterinary assistant to Hold the horse's lead rope.

Holding the horse's lead rope is necessary, when restraining a horse for a routine veterinary procedure by the veterinary assistant.

Always hold the lead rope in the right hand by coiling the excess rope on the hand in the other hand.

Lead the left shoulder of the horse with the assistant's right hand with the excess of rope in the left hand of the assistant to avoid serious injury when the horse decides to bolt.

It becomes important to stable the horse by calming the horse before the routine veterinary procedure.

A leather band should be used in the rope by being tightened behind the legs of the front and by further fastening.

Remember not to harm the back of the horse by excessive fastening.
