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
Answer: reproduction
Explanation: the process by which an organism produces its offspring is called reproduction.
Because its an educated guess witch means its just a guess then you try to get the data that might support thats why it comes first
Answer:
Traits acquired during an organism's lifetime cannot be passed
Explanation:
<em>The law of use and disuse of organs as postulated by Jean Lamarck was wrong due to the fact that environmentally acquired characters cannot be passed to offspring.</em>
Changes to organisms that are not the level of the gene cannot be passed to the offspring. <u>For example, a wrestler that got big muscles due to constant work out cannot pass big muscles to his offspring. The offspring will need to work out in order to have big muscles. This is because big muscles in the wrestler is environmentally acquired.</u>
Only changes that happen to the genome of an organism (mutation) can be passed to offspring.
The probability of the offspring being herterozygous 50%
