The two species probably had a common ancestor, but split and changed from evolution.
Answer:
C. Population shrinks; 15 birds in the end
Explanation:
Let us understand some of the given terms;
immigration is a form of migration in which organisms comes into a territory.
emigration is a form of migration in which organisms leaves a place
population is a group of organisms of the same species
Given:
Population = 21 birds
Immigrant = 3 birds
Emigrants = 9 birds
Population change = total number of birds + immigrant - emigrants
= 21 + 3 - 9
= 15 birds
The population will shrink giving 15 birds in the end
Purple white and lavendar four oclock flowers why did the four o'clock flower plant give three phenotypes instead 2 is a genotype that is 2:2 Rr and rr.
The 4'o clock plant, phenotypes , exhibits partial dominance in flower colour, which is why the F1 plant produced by crossing a pure Red flowered plant (RR) with a pure White flowered plant (rr) has pink flowers (Rr).When an F1 plant (Rr) crosses with a pure white flowering plant (rr), the resulting plant will have a genotype that is 2:2 Rr and rr.
The phenotypic, however, will be 2 pink and 2 white at a ratio of 2:2.
The offspring's phenotypic ratio will be 2:2.
Rr × rr
!
Rr rr rr

<span>Post-medieval people did not take the best care of their teeth. Poor diet combined with poor hygiene practices lead to tooth decay and tooth loss. Many people of the time were wholly unaware that poor oral hygiene can lead to other health problems so taking care of them was not a priority.</span>
