Answer:a) a sturdy-finned, shallow-water lobe-fin whose appendages had skeletal supports similar to those of terrestrial vertebrates.
Explanation:
An ancestor - An earlier type of a species at any distant time — a progenitor.
A tetrapod is any vertebrate with four limbs. It includes any vertebrate (such as birds or snakes) that have evolved from early tetrapods — especially all members of the superclass Tetrapoda.
The presence of bones that support the appendages in Lobe – fin fish were found to be similar to the categorical skeletal supports found in the limbs of sample tetrapods. The sub class crossopterygii includes the Lobe – fin fish, which is seen as one of the recent common ancestor of living tetrapod today.

Answer: Exploitation, invasive species
If the government introduces laws prohibiting hunting, it would somewhat reduce the impact of exploitation would have on the biodiversity because hunting is mainly done for the purpose of fun or to derive valuables from animals like skin, horn, ivory, venome for selling them in the international market and making huge profit from them. Introduction of prohibition law on hunting will reduce killing and exploitation of animals for their valuables.
If laws prohibiting introduction of new plant or animal species within the country are passed, it will curb the effect of invasive species would have on the seas. Invasive species are those living species which are arrive or immegrate to new locations in search of resources. These species compete with native species which results in decline of native species. This will result in disturbance in actual sea biodiversity as this will result in decline in native sea species and may also lead to extinction of native species.
