Over abundance of nutrients in the water is most likely to cause harm to which group of organisms?

Biology
1 answer:
telo118 [61]3 years ago
5 0

Answer:

Option-C

Explanation:

The flow of nutrients from the sewage and industries is the cause of the nutrient pollution in water bodies. These chemicals get accumulated in the water bodies affecting the aquatic ecosystem to a very large extent.

The increased level of nitrogen and phosphorus causes eutrophication which is also known as algal-boom. These nutrients cause the massive growth of algae which decreases the oxygen level of the water bodies. This increases BOD level of the water bodies which does not allow the growth of other aquatic species.  

As a result of this, the dead zones are created where nothing can survive and therefore is the correct answer.

Thus, Option-C is the correct answer.

Answer:

Option C

Explanation:

Image for the question is attached here

Solution

It is given that the membrane is permeable to both salt and water.  

Thus, water will form region of high concentration to the region having low salt concentration. The same applies to the movement of water molecule.  

As we can see in the image, Side A has higher water concentration and side B has higher salt concentration.  

Thus water will move from side A to side B and Salt will move from side B to side A.

Hence, option C is correct

Answer:

At the bottom you have the producers aka auto trophic livings (which use inorganic compounds to grow, produce energy, matter and so on..). These organisms would be plants, Cyrano bacteria, over all any organisms that do photosynthesis.

Using a microscope, Quinlin notices a small green organelle inside a cell. Which of the following is most likely to occur first
jek_recluse [69]

Answer:

D.The light-dependent reactions absorb sunlight and transfer the energy to electrons.

Explanation:

Firstly, the organelle that was described as small green organelle inside a cell as noticed by Quinlin is the CHLOROPLAST. Chloroplast is an organelle present in the cells of green plants, in fact, it makes plants green. Chloroplast is the organelle where the unique process of PHOTOSYNTHESIS occurs in plant cells.

However, the photosynthetic process is divided into stages namely: light-dependent and light-independent stages. The light dependent stage, which involves the production of ATP (energy carrier) and NADPH (electron carrier), must PRECEDE the light independent stage or Calvin cycle. Chloroplast contains a pigment called CHLOROPHYLL, which absorbs light energy from the SUN in order to power the light dependent stage of photosynthesis.

Hence, the light-dependent reactions, which absorb sunlight and transfer the energy to electrons must occur first in the organelle.
