<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2>

\huge\textbf{Cell Theory}

the Cell Theory was give by German scientists, Schleiden and T.Shwan in 1839. It stated that,

  • All organism are composed of one or more cells

  • The cell is the structural and functional unit of life
  • It is a de novo structure, that means it COULD arise from non living thing which was incorrect.

It was corrected by the German pathologist  Rudolf Virchow in 1855. He made a convincing case, corrected and added the third point of the cell theory. It is,

  • Cells can arise only by a division of pre-existing cell. It is <u>NOT</u> a de novo structure.

Cell theory brought a great evolution in the field of biology which established the function of organism is the result of activities and interaction of the cell units.

\huge\textbf{Question:}

  • <u>Flask 1</u>: It is observed that there are no micro-organism, this is because the meat is sealed and no micro-organism could enter through it.
  • <u>Flask 2</u>: It is observed that there are micro-organism present because meat is not sealed but open.
  • <u>Flask 3</u>: As the S tube is used, the micro-organism are not able to reach the meat because of the curvy path

These observations support the  point that<u> cells could arise only by a division of pre-existing alive cells</u> because in Flask 1 when there were no micro-organism present so there was no organisms found so no micro-organism arised, In flask 3 the S tube was used so no micro-organism could reach the meat thus there were no organism there which could divide to reproduce. The flask 2 was open, so the micro organisms reached the meat so they divided which means Cells can only arise by a division of pre-existing cells.

Which of these statements best describes a similarity between photosynthesis and dissolving in the sea?
Mama L [17]

The correct answer is D. Both absorb carbon dioxide from the atmosphere.

The process of photosynthesis is carried out using atmospheric carbon dioxide by green plants. Many gases including carbon dioxide are dissolved in seawater. Some of the carbon dioxide gas remains in dissolved state but most of the carbon dioxide is reacts with water to form carbonic acid. Dissolved gases in seawater make balance with atmosphere by mixing of the surface by wind and waves. Therefore, both photosynthesis and sea water take carbon dioxide from the atmosphere.

PilotLPTM [1.2K]

Answer:The based on this information interaction between these two species can best be described as COMPETITION. Correct option is B

Explanation:

Competition occurs between two species that shares the same requirements ( especially food) for survival.

Both the Western Toad and the Bull Frog has a similar niche because they require the same type of food (beetles, bees, and small aquatic insects) to survive in the environment of Arroyo Seco. Only one of the species will coexist in that environment and it's usually the survival of the fittest.

This explains the competitive exclusion principle proposed by Georgii Gause in 1934.
