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.
Answer:
No, Giardia is a protozoan that does not cause eosinophilia.
Explanation:
Eosinophilia refers to an increase in the number of eosinophils in the blood. The eosinophil is one of the white blood cells. When this occurs, the circulating eosinophils might be over 400 or 500.
Many factors might cause. One of them is parasite infections, in which helminths trigger the IgE generation, producing eosinophilia.
In the presence of the parasite antigen, eosinophils have a shorter medullar generation time, and they express a higher number of receptors for IgE and IgG. Their function is to damage the parasite, directly or indirectly, and to decrease the damages caused by their presence.
Giardia, among other protozoans, does not cause eosinophilia. Yet some other protozoans and parasites might induce it.
