The injury from machinery is a hazard of commercial fishing.
<h3>What does commercial fishing mean?</h3>
Commercial fishing is the activity of catching fish and other seafood for profit, particularly among wild species. It supplies a large amount of food around the world, but those who practice it as an industry sometimes look for long conditions from the ocean's limits, in adversaries.
If any damage to machinery occurs, it will end commercial fishing, causing deaths and oil in the seas.

Answers:
thorium-234
Explaination:
Isotopes are defined as the variants of a particular chemical element obtained by radioactive decay which makes it differ in neutron number and nucleon number but have the same number of protons in each atom.
Uranium-238 produces thorium-234 by alpha decay. alpha particle is a helium nucleus which carry 2 neutrons andn 2 protons with the mass number 4. In alpha decay, nucleus emits alpha particles which tranforms or decay into an atom with a mass number 4 less and an atomic number 2 less.
The equation for alpga decay is attached below:
Hence, the isotope is thorium-234 .

Answer:</h2>
The First step in DNA replication is the unzipping the two strands. This process is carried out by the DNA helicase
Answer:
<u>B) introduction of a non-native animal species</u>
Explanation:
The introduction of invasive species within an ecosystem can result in irreversible, permanent and long-term instability of most ecosystems. The other answer choices are natural occurrences that seldom result in a long period of instability.
Answer:
ATP and NADPH are the products of light reaction of photosynthesis process.
Explanation:
There are two stages of photosynthesis i. e. light dependent reactions and light independent reactions. In light dependent reaction stage, two molecules are formed such as Adenine tri phosphate (ATP) and Nicotinamide adenine dinucleotide phosphate
(NADPH) with the help of light energy. ATP is energy rich molecule and NADPH is a reducing agent which is used in the light independent reaction stage.
