Answer:

A) It is coenocytic.

Explanation:

Coenocytic refers to a cell which is characterised by multiple nuclei in it. The multinucleate condition arises when the cell undergoes mitosis division in which only the karyokinesis takes place but no cytokinesis occurs.

Since no cytokinesis occurs, therefore, no cell gets separated and multiple nuclei share one cytoplasm.

In the given question, the green algae which are characterised by the multiple nuclei are, therefore, coenocytic algae like in the seaweed Codium.

Thus, Option-A is the correct answer.

You study how blowflies aid in animal decomposition in forest ecosystems. when would be the best time for you to do your researc
Studentka2010 [4]

The answer is; in the summer

Insects such as blowflies increase their population in the summers when the temperatures are warm. One reason is that most insects are ectotherms hence their body temperatures are dependent on ambient environmental temperatures. In addition, the maggot stage of the blowfly pupates mostly in warm and dry conditions hence increasing winged flies populations in the summer.

In lecture, I mentioned most lakes are phosphorus limited. However, the most severely eutrophic lakes are often nitrogen limited
KIM [24]

Answer:

Phosphorus is essential for growth of plants and other organisms. When concentration of phosphorus mostly from high breeding rate e.g., pigs, cattle etc. rise in water it causes severe growth of plants and algae as well as phytoplanktons. As a results layers of phosphorus start to release phosphorus as well due to positive gradient. These reactions in water are iron-redox reactions that are crucial for the release of phosphorus.

When too much phosphorus accumulates, it produces a degrading growth feedback in plants, algae and phytoplanktons that then shift toward excessive nitrogen available from fertilizers and cause a flip from P to N. Cynobacteria now dominates and denitrification as well as nitrification takes place simultaneously.

Severe eutrophication induces hypoxia in water that cause a major damage to plants biodiversity in the environment.
