Answer:
The answer is A.
Explanation:
Phylogenetic trees are only concerned with hard data (time points of when species evolve) and not soft data like how great a species is.
as in any liquid, as heat is added, solutions become more capable of holding more dissolved material . (not sure if this is what you're asking as it seems to be missing information)
Answer:
Trophic level
Consumer
Producer
Explanation:
All living organisms require energy for their life processes, which they obtain by taken in food. In an ecosystem, this food is derived when organisms feed on each other. This process that eventually leads to a flow of energy within organisms is called FOOD CHAIN.
A food chain or food web always begins with a unique set of organisms called PRODUCERS. Producers are autotrophs capable of harvesting light energy from the sun and use it to produce their food (chemical) in a process called PHOTOSYNTHESIS. Other organisms called HETEROTROPHS feed on these producers to derive energy. In ecology, they are called CONSUMERS. Other consumers feed on the previous ones also to get energy.
Hence, each step of the food chain is occupied by organisms that obtain and store energy by feeding on another organism. This step is called TROPHIC LEVEL.
In a nutshell, a PRODUCER (usually plants) starts the food chain/web due to its photosynthetic ability. This producer gets eaten by an organism called CONSUMER and in the process, the energy and nutrient stored in the producers flows to the consumer. Another consumers feeds on the previous one and the energy keeps flowing. Each step of the food chain occupied by an organism that stores and transfers this energy is called TROPHIC LEVEL.
The correct answer is D. Bird flu.
Polio and smallpox are very rare today as they were eradicated hundreds of years ago and TB has been around for maybe thousands of years. Bird f!u was discovered in 1957.
Answer:
involuntary muscle
Explanation:
Involuntary muscles are those that cannot be controlled by will or consciousness and are frequently associated with organs that contract and relax slowly and regularly. Because there are no striations when viewed under a microscope, involuntary muscles are also known as smooth muscles or non-striated muscles.
