Explanation:
Meiosis is known to be a process of reducing the number of chromosomes in a diploid to half.
And it should be noted that , meiosis requires the pairing of two chromosomes sets.
Therefore in this case, before meiosis can occur in the haploid, it must involves two haploids. This means that two individual haploid will fuse together to form diploid meiocyte, which will allow meiosis to occur.
This is the reason why meiosis can only takes place on haploid species.
In summary, it should be noted that, meiosis can only takes place in a diploid and two individuals haploid [ haploid species] that can fuse together to form diploid, but not in a haploid individual.
In marine environment, many animals confuse the plastic littering the oceans for food including sea turtles. Once in these animal bodies the plastic accumulates, and the chemicals can cause excess estrogen to be produced, which has led to discoveries of male fish with female sex organs. For sea turtles, the plastic blocks their digestive tract and the food that is trapped releases gases that render them buoyant, and unable to dive for food. The turtle was slowly starving because a single use plastic bag, which she had eaten, was blocking her digestive tract.
The plastic contains destructible and harmful agents that is not good for human and animals health.

The spinal cord and the brain make up the central nervous system, and spinal cord nerves carry most messages between the brain and the rest of the body.
The vagus nerve carries the signal from the brain to the heart.
