They both grow and develop.
Answer:
an autotroph is a <em>producer</em> in the food chain
Explanation:
An autotroph produces its own food from light, heat, and/or environmental chemicals, often including water and/or carbon dioxide. It is a <em>producer</em>, not a consumer, in the food chain.
Answer:
B. 5
Explanation:
5 Although neither enzyme has its maximum catalyzing rate at 5, they are equal in their rate of catalyzing ability at this pH. Pepsin has an optimal pH of 3 while trypsin has an optimal pH of 8.
First pass metabolism of a drug is said to occur when the concentration of a drug that is administered orally is significantly reduced before it reaches the systemic circulation.
First pass metabolism usually occur in the liver.
The routes of drug administration that avoid complete first pass metabolism are: sublingual, transdermal, rectal and inhalation.
Answer:
Acid rain refers to the rain which acidic in nature having a form of precipitation and elevated levels of hydrogen ions (low pH). The normal pH of rain is around 5.6
Rising concentration of Sulfur dioxide (SO2) and nitrogen oxides (NOx) in atmosphere is one of the cause of acid rain. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are released by vehicles, fossil-fuel power plants and oil refineries.
When a sulfur dioxide and nitrogen oxides released in air they mix with oxygen, water and other chemicals in the air and form sulfuric and nitric acids. sulfuric and nitric acids mix with precipitation and its pH level is about 5.2 or below.
Hence, rising concentration of SO2 And NO2x is one of the biggest reason of acid which damages agriculture, buildings and wildlife et-cetra.
