All organisms need energy to survive. This is supplied through photosynthesis or from consuming another being in the form of calories (Yes, calories are a form of energy).
Answer:
a. Mitochondrial DNA is inherited through the maternal lineage.
d. Mitochondrial DNA can therefore be used to confirm or eliminate a person's relationship within a maternal line, but cannot be used to identify a specific individual.
Explanation:
DNA is the genetic material. Nuclear DNA profiling is used to identify a person since each individual has unique DNA. Mitochondrial DNA exhibits maternal inheritance. All the offspring of a female share the same mitochondrial DNA. Therefore, all the individuals that are related by maternal lines, share the same mitochondrial DNA. The profiling of their mitochondrial DNA would not allow the identification of a person when individuals share maternal lines.
Answer: A food chain or food web provide information on the eating patterns of organisms, how energy is transfered from one organisms to another and the flow if energy in the ecosystem.
Explanation:
Food chain is the link of network that that starts from producer to the consumer and finally ends at the predator species and decomposer species in the ecosystem. It describe the feeding relationships among organisms.
Food web contains interconnection of several food chains in the ecosystem. It shows several feeding relationships in food chains .
Both food chain and food web provide information of how organisms are interconnected, their eating patterns, how energy is transferred from one organisms to another and flow of energy in the ecosystem.
compound consisting of a nucleoside linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA.
