Answer:
The correct answer is option B. lobe-finned fish.
Explanation:
Lobe finned fishes or the Sarcopterygii is a group or clad of fish that contain the coelacanths, tetrapods, lungfish, and other fossil relatives. ray-finned fishes and lob finned fishes are the are sister groups.
The major characteristic feature of this fish is the presence of lobe in their fins. The ancestral records explained that the land-dwelling tetrapods are evolved from the lobe-finned fishes around four four hundred million years ago.
Thus, the correct answer is option B. lobe-finned fish.
Answer: The endocrine system consists of Glands.
- The glands that make up the endocrine system produce chemical messengers called hormones that travel through the blood to other parts of the body. Important endocrine glands include the pituitary, thyroid, parathyroid, thymus, and adrenal glands.

In Earthquake testing, the engineers are using the world largest shake tables to test new construction methods for buildings in the areas prone to the earthquake.
<u>Explanation:</u>
They believed that they have the devised a system to build the taller wood-frame buildings that can still safely withstand even very powerful tremors. To withstand the collapse, the buildings need to redistribute the forces that travel through them during a seismic event.
Shear wells, cross braces, diaphragm, and moment-resisting frame are the central reinforcing the building. Shear wells are the technology of the useful building. That helpful to transfer the earthquake forces.
