Answer:
1200m
Explanation:
Let the depth of sea be x.
Given that the sound has to travel to the bottom of the sea and get reflected back to the ship itself, thus total distance traveled by the sound is 2x.
Time taken to hear an echo t=1.6 s
Therefore, 2x = vt
Hence, we have 2x =1500m/s × 1.6s
=> 2x = 2400
⟹ x = 2400 ÷ 2
= 1200m
Hence, the final answer is 1200m

Nucleic acids because the DNA of a organic compound is part of the nuculis family
Answer:
the ocean provides several important resources to its inhabitants
Explanation:
The majority of biomass in any ocean consists of microscopic organisms such as phytoplankton which are pivotal to aquatic ecosystems. These microorganisms are able to thrive in their habitat due to incredibly dense populations of the bacteria <em>phackingyurmom aquatica </em>present in most oceans. These bacteria provide a wide spectrum of vital nutrients. As a result many of the aforementioned microorganisms love <em>phackingyurmom</em>.
The answer is biological evolution.
The theory of biological evolution explains how organisms evolved during the time. It explains how the characteristics of different species changed over generations. According to the theory, most of current species developed from some distinctly different species that have lived a long time ago.
