A cladogram is a diagram of branches that show the cladistic relationship between animal species. A node you can expect to find on the cladogram would be <span>Deuterostome development. Examples of deuterostomes are starfish and sea cucumbers.</span>
Answer: option B) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population
Explanation:
Sympatric speciation is an event/situation whereby organisms of the same species:
- live in the same territory or nearby territories ( i.e do not live in geographical isolation)
- DO NOT interbreed, but select a sexual mate from a much diverse territory to yield new species or offsprings.
This sexual selection then results in generations of offsprings that are genetically different from the rest of the same species due to uneven gene flow or disruption of alleles among the population of same species.
Thus, only option B is true.
Answer:
2. synthesize its own food
Explanation:
Based on how they obtain their nutrition, living organisms has been classified to be either producers, consumers, or decomposers. Producers are organisms capable of synthesizing their own food using light (photosynthesis) or inorganic chemicals (chemosynthesis).
Consumers, on the other hand, cannot synthesize their own food and hence, rely on other organisms to obtain their energy source. Consumers feed on other organisms to obtain energy. In this question, a fruit fly is classified as a CONSUMER because it cannot synthesize its own food.
Answer:
Decomposers are responsible for breaking down dead animals bodies into waste, more commonly known as food for themselves, and a more clean ecosystem. You can thank decomposers such as mushrooms and fungi for making sure the ecosystem does not consist of dead bodies.
