The right option is; d. consumers
All animals are consumers
Consumers are organisms that usually feed on other organisms or organic matter in order to gain energy because of their inability to manufacture their food from inorganic sources. All animals are consumers and they are also known as heterotrophs. There are different types of consumers. They include; primary consumers (herbivores e.g. goats, cows), secondary consumers (carnivores e.g. wolves, crocodile), and tertiary consumers (large carnivores e.g. eagle, lion)
Answer:
Cytosine nucleotides
Explanation:
In most organisms, the methylation of DNA exists in three different sequence motifs. These include: CG (or CpG), CHG or CHH (H represent A, T or C). In plants, cytosine can be methylated at CpG, CpHpG, and CpHpH regions (H represents any of these nucleotide A, T or C except guanine. DNA methylation is almost majorly found in CpG dinucleotides, with the cytosines on both strands usually always being methylated in mammals.
Answer: B. Random mating
Explanation:
Random mating can be define as the individuals of one sex are potentially be the partners of the members of the opposite sex. It is also called as panmixia. Here, the chances of getting mates is certain. It occurs in large population. The physical and geographical barriers can prevent the random mating. In this allelic frequencies will not vary if the mating is conducted in a single population.
