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:
A) Chromosomes are made of DNA
C) Alleles are the different forms of a gene that can exist
D) Chromosomes contain genes that control the inheritance of traits.
Explanation:
Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.
