Ans. (D) All of these.

Sewage treatment is defined as the process that removes contaminants from the municipal wastewater, having industrial and household wastewater, including sludge.

The secondary treatment of wastewater involves removal of colloidal and dissolve organic compounds. These compounds require oxygen for their breakdown processes. Thus, removal of these compounds decrease the BOD (biological oxygen demand) of water.

the tertiary treatment includes processes that improves the quality of treated water before releasing it to environment. It involves removal of excess nutrients present in wastewater, such as phosphorus and nitrogen as these nutrients enhance growth of algae and cause algal bloom.

Tertiary treatment also includes addition of disinfectants to remove microorganisms present in it.

Thus, the correct answer is option (D).

Explain how a concentration gradient, a membrane protein, and hydrogen ions work together to provide a mitochondrion with the en
gladu [14]

During the electron transport, chan energy stored in electrons is used to pump hydrogen protons from the mitochondrial matrix to the intermembrane space. The numbers of protons increase this creates a chemical gradient(because there is a higher concentration of ions) and an electrical gradient(because the intermembrane space becomes more positive than the matrix because of the protons-H⁺). Those protons need to flow towards the matrix for equilibrium to occur. As we know the inside membrane of the mitochondria has a reduced permeability. The main place where protons can diffuse is the ATP-synthase(a protein that turns ADP and inorganic phosphate into ATP). When protons pass through they release the energy necessary for this reaction to occur(ADP+H₃PO₄-->ATP+H₂O)

Technology has changed  the way scientist  conduct  their  research. Provide two  pieces of  evidence  from the film  to support
Anon25 [30]

Technology is important in order to conduct research on lions in Gorongosa national park. Studying lions is not that easy, however, applications of technology like satellite collars that demonstrate complete information on the daily activity of lions has greatly developed the study of lions.  

As each lion exhibit a specific pattern of whisker-spots on both the side of its face and similar to human fingerprints, no two lions share the same whisker patterns and even do not modify with time. Hence, with the help of photos, the lions are being identified conclusively.  

In order to find the age of a lion, various characteristics like coloration and size of the body, condition of the tooth, mane size, and a technique of evaluating age using coloration of the individual nose are used.

Mike is a diabetic and cannot let his blood sugar get too high, what type of biomolecule should he avoid in foods?
vichka [17]

Carbohydrates

Carbs digest <em>very</em> quickly and will quickly turn into sugar, which will result in high blood sugar. So Mike should not eat too much carbs at once. :(
