Explanation:
1. Since the Lions are the predator and Gazelles are the prey therefore a predator-prey relationship exists between them. The predator-prey relation is also associated with the food chain in an ecosystem. If the number of prey is reduced then there are chances that the number of a predator will also be reduced but
2. The Lion is not just the predator of Gazelle but other animals also like deer therefore they can shift their resource of food from gazelles to another organism.
3.The change of the ecosystem will change the population of the predator as the population are adapted to grow in a particular ecosystem and change of population could reduce the population of a predator.
Answer:
The frequency would be stable.
Explanation:
Based on the most common symptoms of cystic fibrosis, the disease only appears on adults and elderly. This feature means that the frequency of the disease would not drop or raise because they would still reproduce and pass the allele from generation to the next, maintaining the frequency stable.
Answer:
Analogous or convergent structure.
Explanation:
Analogous structures can be defined as structures that have similar purposes but look completely different from each other. in other words it means that they serve the same functions in different species, but they are independently evolved. Examples of analogous structures are
- wings on butterfly, bats and birds
- Fins in penguins and fish
Hemoglobin is affect by sickle cell anemia.
The period is the time it takes the satellite to make a complete orbit around the central object. As the distance increases, so does the period because the orbit becomes longer because the radius increases.
Hope this helps!!
