Answer:
Rice plants possesses several traits which allow sthem to grow in large amount of water because standing water helps them to produce air channel known as aerenchyma that connects roots with shoots and transport oxygen to submerged tissues. Standing water also help many weed to grow and rice plants also takes nutrients from them as well.
Genes are responsible for the traits that allow rice plants to grow in large amount of water but if the gene of rice plant is genetically modified with new gene which is resistant to drought, that can allow the rice to grow in less water.
The genetically modified rice plant then do not require large amount of water and can grow easily.
Cyanobacteria convert nitrates from the water into nitrogen gas (N2<span>) that is released into the atmosphere</span>
I believe it’s your answer is c
Answer:
The problem: Under Martian gravity, the soil can hold more water than on Earth, and water and nutrients within the soil would drain away more slowly. Some conditions would make it difficult for plants to grow on Mars. For example, Mars's extremely cold temperatures make life difficult to sustain.
Scientists have conducted plant experiments simulating Martian conditions using volcanic soil in Hawaii, which is known for its similarity to Martian soil. These experiments found that plants can actually grow in these soils.
There are other aspects future Mars explorers will need to consider when growing plants on that planet. As mentioned earlier, Mars’s atmosphere is mostly carbon dioxide, and plants need this gas just as much as we need oxygen to breathe.
Answer:
Secondary succession is a faster process than primary succession because some cones or seeds likely remain after the disturbance.
