Do you think killing lionfish is ethical? Why or why not?

Answers

in my opinion, killing anything is not ethical. this goes against any rights even though a lion fish is not human

Answer:

Well I don't like killing things but lionfish are technically taking over the ocean since they are traveling everywhere and a hurricane caused six fish from an aquarium to accidentally get swept out into the Atlantic Ocean. Female lionfish produce thousands of eggs at a time, which has allowed their population to increase rapidly in the Atlantic. There’s no firm estimate of the number of lionfish in the Atlantic Ocean right now. However, it might be as many as 375 to 1,000 lionfish per acre of the ocean. These fish have predators such as sharks and scorpionfish in their natural habitat. However, they don’t have many natural predators in the Atlantic Ocean, where the typical predatory animals don’t seem to recognize lionfish as food, so it probably is ethical.

cell theory establishes which of the following conclusions about cells?
A) all cells have the same size and shape
B) all cells form by free-cell formation
C) all cells are produced by other living cells
D) all cells have a cell wall

Answers

Answer:

C) all cells are produced by other living cells

Explanation:

Cell theory establishes the conclusion that " all cells are produced by other living cells". According to cell theory all the living cells are generated from pre- existing cells. Thus, option C is correct.

What is cell theory?

Cell theory is a scientific theory given in nineteenth century and according to cell theory " cell is the structural and fundamental unit of life" and " every living cell is made up of pre existing cell".

The cells in multicellular organisms function differently from those in single-celled organism. A unicellular depends upon only one cell for all functions occurred in body. On the other hand a multicellular organism has cells specialized to perform several body functions that combinedly support the organism.

The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialized it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.

Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.

In unicellular organism division of levour is at the orgneele level on the other hand in multicellular the division of lavour at cellular, tissue, organs and organ system level.

Unicellular organism has simple body organization and multicellular organism have complex body organism.

Therefore,Cell theory establishes the conclusion that " all cells are produced by other living cells". According to cell theory all the living cells are generated from pre- existing cells. Thus, option C is correct.
