Answer:
Random segregation of homologous chromosomes makes the two siblings differ from each other for 0-23 chromosomes.
Explanation:
Sexual reproduction adds genetic variations in the progeny by crossing over, independent segregation of homologous chromosomes and random fusion of gametes. Without crossing over, independent segregation of homologous chromosomes towards opposite poles during anaphase I of meiosis may result in two siblings to vary from each other for 0-23 chromosomes.
There is an equal probability of each of the two siblings to get a chromosome from mother or father. Hence, irrespective of the variations provided by crossing over, random segregation of homologous chromosomes makes the two siblings differ from each other for 0-23 chromosomes.
B would be your answer, let me know your scores.
Answer:
B. Food was a limiting factor.
C. As long as Ling keeps adding more food, the guppy population will continue to grow
Explanation:
Limiting factor refers to biotic or abiotic factors that limit or affects the growth of species. In the population of guppies, food was a limiting factor that affects their population growth. Indeed!, it is vivid from the experiment that after Ling increases the amount of food being given to the guppies, there is a significant increase in the population growth.
We can thereby conclude that the following statements that supported these data goes thus;
Food was a limiting factor and as long as Ling keeps adding more food, the guppy population will continue to grow.
It drops down to 1 percent
The Epiglottis prevents food from entering your lungs.
