The question is incomplete. The complete question is - A student poured a solution of bromthymol blue indicator into three test tubes. Then, he placed and aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Brothymol blue turns from blue to yellow in the presence of CO2.
Which process would you expect the organisms in the test tubes to carry out-- cell respiration, photosynthesis or both? When would you expect each process to occur?
Answer:
Photosynthesis is the process of the formation of the food in case of plants in the presence of sunlight with the help of carbon dioxide, water and soil. The light energy is converted into the chemical energy.
The beaker is blue because plants uses carbon dioxide for their food preparation. When the beakers are kept in the dark place, instead of photosynthesis cellular respiration occur that made energy from the food for their survival.
They are better competitors because they emerge earlier in the spring, grow rapidly, and are impacted by few, if any, natural predators. When invasive plants are allowed to grow unchecked, many native plants and the wildlife species that rely upon them suffer.
Answer:
A plant cell is surrounded by rigid cell wall whereas animal cell does not have cell wall. Presence of a large vacuole in plant cell, which is small in animal cell. Plant cells are larger than animal cells. Plant cells have plastids whereas animal cells do not have plastids.
Explanation:
Proglottids are segments in cestodes that contain bot the male and female reproductive organs. These segments go ahead to make eggs and then dettach form the worm. They are excreted and become agents of infection on the next hoist. Proglittids formed near the neck of the worm are immature while those at the tail end are literally bags of mature eggs.
The scolex is the head of the worm that is attached to the host. It is also the part that ‘sucks’ nutrients from the host. It has hooks that it uses to anchor itself in the host. In some species, rather than hooks, there are suction-cups that use suction for anchorage.
