Answer:
The economists typically receive information premised upon the information gathered during controlled studies. A further explanation is provided below.
Explanation:
- The investigators typically add particular manipulation throughout the observational investigation and analyze the consequences.
- The survey was performed here because the investigators simply would be required to examine the influence of fertilizer on the development of plants. Each assistance must be applied.
D. it produces male and female sex cells
In meiosis, a cell
splits into four cells, also splitting the chromosome count in half from
the original cell. This is a critical stage for sexual reproduction in
that the cells then match up with other haploid cells produced by
meiosis from another parent to create a new organism. These sex cells
have both male and female chromosomes and the resulting sex depends on
how the cells match up with those of the other parent.
Answer: The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes

Phytoplankoton are the primary energy producers of the ocean ecosystem. They create the energy from the light sources such as sun. They convert the obtained light energy into carbohydrates by the process of photosynthesis. The energy produced by the phytoplankton is not consumed by it. These are the important food sources for the aquatic animals in order to support the food chain. These are considered as the foundation of the aquatic food web. These phytoplanktons even cause death of the organisms. When the phytoplankton die it sinks to the bottom of the water body and the bacteria which feed on the dead phytoplankton release oxygen making the marine life suffocating. These phytoplanktons produce chemical energy from sun light. These produce carbohydrates by utilising carbon dioxide from atmosphere resulting in water and oxygen as the end product.
Therefore, Phytoplanktons act as PRODUCERS in an ocean ecosystem.
