Explanation:

The correct amino acid for the ACG sequence is Threonine (Thr).

During translation, a messenger RNA (mRNA) sequence is read in the ribosomes to synthesize a polypeptide chain (i.e., a protein).

The correct order of triplets of nucleotides or 'codons' in the mRNA determines the order of amino acids in the nascent polypeptide chain.

Each codon determines a specific amino acid. In this case, the codon ACG encodes for the amino acid Threonine.

In conclusion, the correct amino acid for the ACG sequence is Threonine (Thr).

Wandering spiders, also known as Ctenidae, are skilled predators that employ unique hunting strategies to catch their prey without relying on a web. These spiders exhibit exceptional agility and speed, allowing them to actively pursue and capture their targets.

A key aspect of their hunting strategy is their heightened touch sensitivity, which they use to detect minute vibrations in the environment. This sensitivity is mainly attributed to specialized sensory organs called trichobothria. Trichobothria are hair-like structures located on the spider's legs and are extremely responsive to even the faintest air currents and vibrations.
When a potential prey item, such as an insect, moves nearby, the trichobothria detect the subtle disturbances in the air caused by the movement. This information is relayed to the spider's central nervous system, alerting the spider to the presence and location of its prey.
Once the wandering spider becomes aware of the prey, it stealthily approaches and uses its powerful legs and venomous bite to swiftly immobilize the target. In some cases, the spider may also utilize its impressive jumping ability to close the distance and capture the prey.
In conclusion, wandering spiders are highly efficient predators that employ their exceptional touch sensitivity, through trichobothria, to detect and locate prey without direct contact. By combining this ability with their speed and agility, these spiders can effectively hunt and capture prey without the need for a web.
