Answer. After cytokinesis is completed at end of meiosis - I two haploid cells are formed.on:
B Phytoplankton - Zooplankton - Arctic cod - Ringed sal
Explanation:
The food chain that describes the path through which energy takes will be phytoplankton-zooplankton-Arctic cod-Ringed sal. Energy moves in the ecosystem from producers to primary consumers then secondary and tertiary consumers.
- Autotrophs are those organisms that manufacture their own food. The use chemical substances from the environment to produce their nourishment which serves as the source of energy for the whole ecosystem too.
- Autotrophs are the producers in any ecosystem and they are usually the plants.
- The phytoplankton is an autotroph.
- Next up are the primary consumers that takes up the produced food by the autotrophs for their own nourishment. In the chain above, the Zooplankton is the primary consumer.
- The secondary consumer that feeds on the zooplankton is the Arctic cod.
- The tertiary consumer is the Ringed Sal which feeds directly on the Arctic cod.

Answer:
KI
Explanation:
From the question, we can see that a qualitative analysis of the compound shows that it has a lilac flame colour. The lilac flame colour corresponds to the potassium ion (K^+).
Again, the test of addition of HNO3(aq) and AgNO3(aq) to a solution is a test for halogens. If the result is a green precipitate, then the ion present is the iodide ion (I^-).
Hence, the compound must be KI.
Answer:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.

When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory.
