<span>It is believed that the coelacanths and lungfish (lobed fin fishes) represent a crucial link between other fishes and tetrapods. The major feature to support the hypothesis is : </span>Their fins have skeletal and muscular structures similar to amphibian limbs.

Explanation:
They live in the host and reproduction occurs there only.
Answer:
The basic processes of cellular respiration are: glycolysis, followed by Krebs cycle, the electron transport chain and chemiosmosis.
Explanation:
This task asks one to arrange the basic processes of cellular respiration in the correct order.
Place the major steps of cellular respiration in order by dragging the appropriate figure to each box.
Cellular Activity 1. Glycolysis pathway- The reaction starts with glucose. In the process, glucose is oxidized and split into two 3-carbon compounds. The byproducts is 2 ATP, 2 NADH, and 2 molecules ofpyruvate.
Cellular Activity 2. Krebs cycle- The Krebs cycle follows glycolysis, its an aerobic process but before the glycolysis end-product enters the Krebs cycle, it must first undergo loss of CO2, oxidation, and attachment to coenzyme A to form acetyl CoA.
Cellular Activity 3. Electron transport chain and chemiosmosis pathway- Here we observe that electron carriers such as NADH and FADH2 that are carrying electrons are removed during oxidation steps gets to the electron transport chain and loss their electrons to the chain.
As electrons move along the chain, the energy they lose as they are sequentially made accessible to lower-level electron carriers and electrons eventually to the final electron acceptor is clipped for ATP production.
I am not sure but I am guessing carbon and nitrogen :)
