Answer; 
-Noble gases or Group 18 elements 
Explanation;
A full valence shell is the most stable electron configuration. Group 18 elements or noble gases such as helium, neon, and argon, have a full outer, or valence, shell. Elements in other groups have partially-filled valence shells and gain or lose electrons to achieve a stable electron configuration.
They are extremely unreactive and do not form bonds with themselves. Solid helium is the the ultimate fine powder being monotomic.
 
        
             
        
        
        
The correct answer is: In both systems, ATP is produced by chemiosmosis.  
Both of the processes, photosynthesis and electron transport chain in mitochondria use chemiosmosis (movement of ions across a semipermeable membrane, down their electrochemical gradient) to produce energy or ATP (via ATP synthase). The movement of hydrogen ions across the thylakoid membrane in order to galvanize the production of ATP is equal to the movement of those ions across the inner mitochondria membrane. Electrons are accepted by NADPH in photosynthesis (but not FADH2 as in mitochondria).
 
        
             
        
        
        
Answer:
A gamete containing an extra chromosome is formed.
Explanation:
Geminal mutations may result in the production of mutant gametes. If such gametes fuse with those from another individual of the opposite sex to form a zygote, the mutation is transmitted to the progeny. A trisomy gamete containing an extra chromosome would transmit the mutation to the offspring after fertilization.
 
        
             
        
        
        
The options are: 
A) Right Frontal Lobe
B) Right Temporal Lobe
C) Left Frontal Lobe
D) Left Parietal Lobe
E) Hypothalamus
Answer:
 The correct answer is D) Left Parietal Lobe
Explanation:
Parental lobe plays an important role in combining and interpreting sensory information coming from various body parts. It process information which allows individuals to know about the position of his body parts.
The damage in the left parietal lobe will affect the right side of the body and cause numbness and impaired sensation in the right side of the body. So the individual who has damaged left parietal lobe will not able to sense any stimulus in his right hand but can still move his fingers. So the right answer is D.
