The ability to maintain vegetation?
Explanation:
Answer:
The answer is C. The cell took in another ancient prokaryotic cell, which began living inside it.
Explanation:
- The Endosymbiont Theory explains the evolution of membrane bound organelles such as mitochondria and chloroplasts.
- According to the theory, mitochondria evolved when an ameoba like organism engulfed bacteria capable of cellular respiration.
- Similarly, chloroplasts were developed when the ameoba like organism engulfed cyanobacteria or blue-green algae capable of photosynthesis.
- These organisms survived inside the ameoba over millions of years to develop into mitochondria and chloroplasts.
- The fact that mitochondria and chloroplasts have their own circular DNA and ribosomes is evidence of the endosymbiont theory.
The appropriate answer is D. Alfalfa. Alfalfa is a legume and these plants play a key role in the nitrogen cycle. These plants house nitrogen fixing bacteria on their roots. The bacteria are housed in tiny round structures of leguminous plant roots. Once the nitrogen is fixed in the soil it can now be used by other plants to make food. These plants include beans peas and peanuts. <span />
Answer:
Cell membrane is considered as boundary of the cell.
Explanation:
Cell membrane is the boundary of the cell which is selectively permeable that allows the micro-nutrients, water and gases like oxygen and carbondioxide etc through the process of diffusion. When the water goes inside due to diffusion it is the indicator that there is less quantity of water present inside the cell as compared to the external environment, this phenomena is called hypertonic.
Its C
On large-scale cheese production, using bought-in cultures is essential because when the milk is coming from multiple farms, often collected over several days, and is pasteurised, the cheese-maker needs to repopulate the milk with lactic acid bacteria in order for it to acidify and to prevent 'bad' pathogenic bacteria
