Answer:
Deep scattering layer, DSL
Explanation:
The deep scattering layer (DSL) also known as "<em>deep sound layer</em>", refers to an oceanic deep layer, more or less defined, that reflects sound and that is formed by a wide variety of animals. It is present in almost every ocean. It is produced by the presence of many organisms of different species that can disperse the sonar waves sent by a sonar equipment.
It was discovered through the ships´ sonar. Whenever they met a layer in which the sound hit, and was often confused with the bottom of the ocean. This is why the DSL is refered to as the "fake bottom".
These animals form layers of not less than 10 meters thick and might easily reach up to 50 meters thick. These layers are often found between 50 and 200 meters deep and can be seen going up and down every day according to the daily vertical migration.

Answer:
Patau's syndrome
Explanation:
Patau's syndrome is a genetic disorder caused by one additional chromosome 13, and therefore it is an aneuploidy caused by an extra chromosome (i.e., a trisomy). Individuals with Patau's syndrome have 47 chromosomes instead of 46 in some or all their somatic cells. This syndrome seriously affects fetal development, usually resulting in miscarriage, stillbirth or in neonatal death. The incidence of this syndrome is around 1/5,000 births.
The layer of the atmosphere where most of the weather happens is called the troposphere.
Decomposers are living organisms that breaks down other living and non-living things into smaller parts.
Decomposers can recycle dead plants and animals into chemical nutrients such as carbon and nitrogen that are released back into the soil, air and water as food for living plants and animals.
