Answer:
Nematode.
Explanation:
Heartworms belongs to phylum Nematoda, their biological name is Dirofilaria immitis. Their body structure is a tiny thread-like parasite roundworm. Adult heartworms always live in the lung arteries and the heart of the dogs and other mammals, it can spread from one species to another by the mosquito bites. Some characteristics of Nematoda phylum are:
1) Their body structure is triploblastic, bilaterally equal and cylindrical in shape.
2) They show a tissue-level organization.
3) Their body keeps a pouch or pseudocoelom.
Answer:
A. Morphology
Explanation:
Why is it A?
Because Morphology is, <u>the branch of biology that deals with the form of living organisms, and with relationships between their structures. </u>This means their structure helps their hunting.
Answer:
Explanation:
The cells in our bodies need oxygen to stay alive. Carbon dioxide is made in our bodies as cells do their jobs. The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out.
Answer:
Remove Na + from the extracellular compartment and assess the early current under new conditions
Explanation:
Na+ is a critical ion that influences the action potential in nerve cells. During the transmission of an impulse, the cell membrane is open so ions can flow through it, i.e., positively charged ions such as sodium ions (Na +) move within the cell, while negatively charged ions move outside the cell. This process produces a change in the action potential by rapidly increasing the positive charge in the nerve fiber, being thus the impulse propagated when this charge reaches +40 mv. In consequence, the effects of Na + on the single-channel current can be analyzed by removing positive ions and determining the change in the reversal potential of this channel.
