What are the options given?
Anaerobic respiration is the process by which some organisms produce energy in the absence of oxygen. Instead of oxygen, organic and inorganic molecules are used as electron acceptors. One example of anaerobic respiration is fermentation.
In latic acid fermentation, one molecule of glucose undergoes glycolysis to produce two molecules of pyruvate. The two molecules of pyruvate then undergo fermentation to produce two molecules of lactate. The lactate will be transported to the liver. The lactate can be reconverted to pyruvate and utilized for energy. Latic acid fermentation occurs in the muscles.
C) make proteins
Amino acids contain nitrogen and amino acids are used to make proteins.
Answer:
A)11,460 years
Explanation:half of a radioactive element represent the time take for half of it's components to dissociate or disintegrate.
For carbonn14 that undergo an emmision to form a stable carbon 14,it moves thus
14C(1 part) ______14C(0.5 parts)_____14C(0.25parts)
i.e it undergo two radioactive decay which means two half lives .
Since each half life is 5780 years ,the age will be 2×half lives= 2×5780=11,460 years
Answer:
The sound will reach my ear in a shorter time in Scenario 1.
The speed of sound waves in solids is faster than it is in gases.
Explanation:
The sound which is produce due to hitting of metal bar with a drumstick reaches to the ears in short time because sound is a longitudinal wave which requires or needs medium for its propagation from one place to another and in solids the particles of medium are close to each other as compared to air so the sound travels faster in solid materials as compared liquid and gases and takes less time to reach my ears.
