Answer:
They are sympatric species.
Explanation:
Sympatric speciation is the presence of two species with same surviving ancestral species in the same geographic area. Sympatric species have numerous characteristics that are common in the same geographical area. They have same evolutionary path therefore they are anatomically similar too.
The answer to this is inherited mutation.
Inherited mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.
Hope this helped :)
Have a great day
The question is incomplete as it lacks the question and has only information regarding the question. however, the correct question is as follows :
How many different genes are contributing to the wingless phenotypes in these mutant fly strains?
Answer:
The correct answer is - Two genes.
Explanation:
In the given question there are two mutation groups based on the given seven results:
1st group :
Mutations 1, complement with 2,4, and 7 and also complement each other, thus, are on the same gene.
2nd group:
Mutations 3, 5, and 6 did not complement each other but complemented with mutations 1, 2, 4, and 7. Thus, these three mutations are present together on a different gene.
Answer:
0.15 m/s² east
Explanation:
We can use following kinematic equation for Uniformly-Accelerated Motion to solve this problem:
<h3>v = v₀ + a × t</h3>
Where <em>v</em> is the final velocity, <em>v₀ </em>is the initial velocity, <em>a</em> is the acceleration and <em>t </em>is the time interval.
<u>The data of the problem is:</u>
- v₀ = - 100km/h (remember to have a frame of reference, I decided traveling west will be towards the negative values and traveling east will be positive).
- v = 0 km/h (the car comes to a full stop)
- t = 3 min
<u>Replacing the data in the formula</u>:
0 km/h = -100 km/h + a × 3 min
It's very important to use the same units when solving problems. I will convert kilometer to meters and hour or minutes to seconds, because the answer choices are given in m/s².
Then:
And considering our frame of reference, a positive sign indicates that the acceleration is east-bound.
