Can cells survive without support of other cells?
Answers
Answer: There are literally countless single celled life forms all over the planet and every creature living is the descendant of single celled organisms. So the answer to your question as written is no, a cell can survive perfectly fine on its own, without the support of other cells, so long as its in a favorable environment.
Explanation:
Answer: No
Cells in bodies of living organisms are designed to help one another, so cells can not live/survive without support of other cells. They work in unity to help our body.

Answer:
Alkanes
Explanation:
There are 3 classes of hydrocarbons based on the on the presence of single, double and triple bond present in them. These classes are mentioned as under:
1) alkanes
2)alkenes
3)alkynes
Alkanes are the hydrocarbons which are compounds of carbon and hydrogen bonded by single bond. Their general formula is CnH2n+2 that means if in an alkane n = 3 then it will have 3 carbon and 2n+2 = 8 hydrogen molecules.
Alkenes are the hydrocarbons which are compounds of carbon and hydrogen bonded by double bond. Their general formula is CnH2n.
Alkynes are the hydrocarbons which are compounds of carbon and hydrogen bonded by triple bond. Their general formula is CnH2n-2.
As explained above, the given hydrocarbon is an alkane because its chemical formula is C3H8 which satisfies the condition for formula CnH2n+2 which is valid for alkanes.

The given statement is False
Bleach such as chlorine when mixed in fertilizers acts as a killing agent for plants .The bleach runoff is not affected by the fertilizers containing bleach as they do not kill the Aquatic flora. Marine bleaching is caused due to high temperature of water not because of the fertilizers. In marine bleaching the coral will expel algae when the temperature of water is high. These results in discoloration of corals making them white and they can survive in this condition. This proves that the bleaching inside the marine system is because of high temperature not because of runoff.

Mitochondria is the site of respiration in plants and animals. Cellular respiration takes place in mitochondria.
The digested food is carried to cells by the circulatory system. The food is then broken down into pyruvate. The fate of pyruvate depends on the presence of oxygen. In presence of oxygen, products formed are Carbon dioxide, water and energy. In absence of oxygen, products are Lactic acid and energy. In case of plants, in absence of oxygen result into Ethanol and enegy, and the same products are released in case of aerobic as in animals.
