DNA and RNA is my favorite subject in Biology and Anatomy
Answer;
Phylum Nematoda.
The heartworms belongs to the phylum Nematoda.
Explanation;
-Phylum Nematoda are un-segmented organisms with anterior lateral chemosensory organs (amphids) and with a persistent blastocoel or pseudocoelom; dorsal and ventral nerve cords in epidermis and excretory system of renette cells or tubules.
-The alimentary canal is provided with distinct mouth and anus (complete digestive tract).
7. The correct answer is photosynthesis.
Autotrophs are organisms which produce food for themselves-from simple to complex molecules. In the case of photosynthesis, producers (plants or some algae) use the light energy to produce complex organic compounds (carbohydrates, fats, and proteins).
8. The correct answer is primary consumers.
Since the pioneer species are usually autotrophs because there is no other source of energy except light energy in the early stages of succession (after the eruption). Most likely, the primary consumer will appear next because they feed upon producers.
9. The correct answer is: they are different populations of fish.
Those two different kinds of fish have unique adaptations that enable them to survive and live in distinct environments. It is most likely that molecular changes underlie adaptation and speciation of those fishes.
The correct answer is (A)
Burning of wood is a chemical change as new substance is formed during the burning of wood which is not reversible.
Now, what happened during the burning of wood?
In the case of burning wood, stored potential energy( in the form of chemical energy) in the log is released due to heating by other excited atoms. This chemical reaction is called combustion that requires oxygen. We can also say that combustion is change of potential chemical energy into kinetic energy in the form of heat.
Saturated fats can turn to trans fats when hydrogenated. This can cause many problems. However if you were to choose one answer from above that best described why eating too much saturated fat is dangerous it would be the third answer...
