Answer:
How do limiting factors affect population size?
Explanation:
Limiting factors are factors that affects the size of a population and slows down its growth rate or stop it in its entirety.
These factors include food, space, temperature, sunlight etc.
Limiting factor like food can affect a population greatly like not having enough preys in a forest, therefore the predators are starved to death or even in a fish pond where there is high competition for space (overpopulated) which leads to oxygen deficiency i.e they compete for oxygen as well, and this can lead to death as well.
Answer:
The blending theory of inheritance by Mendel
Explanation:
Nitrogenous base pairs would form the rungs of the ladder.
Genetic variation can be defined as the difference in the DNA sequences between the individuals in the population
<u>Explanation:</u>
- Antibiotic resistance in bacterial populations is caused by natural selection of bacteria that inherit mutations that make them resistant to the antibiotics,this sentence describes the source and preservation of genetic variation.
- The Mutation is one of the genetic variation or disorder, and probably bacteria choose mutation to become repellent to antibiotics
- In some of the cases of spontaneous bacteria have been obtained from other sets of bacteria through the process and make the bacteria repellent to an antibiotic.
- They survive antibiotic treatment and increase in numbers by natural selection.
- Natural selection can be stated as the process in which organism survive and reproduce adapting to the environment
