<span>The correct answer is ventromedial nucleus of the hypothalamus. This is the correct answer because the ventromedial nucleus is responsible for hunger, food intake, obesity and energy homeostasis. Therefore damage to this part of the brain may have altered Will's hunger and food intake leading to the weight gain.</span>
        
             
        
        
        
<span>The answer is RuBP. The Calvin Cycle consists of three stages: 1. Fixation during which the enzyme RuBisCO incorporates (fixes) carbon-dioxide into 3-PGA; 2. Reduction during which 3-PGA is reduced using NADPH as electron supply; 3. Regeneration during which RuBP is regenerated so the cycle can start again.</span>

The answer is 9.
Explanation:
There are dominant and recessive genes for both the hair color gene and the gait gene in horses, B, b, T and t respectively.
If a black trotter is heterozygous that means it's genotype is going to be Bb and Tt, therefore it will possess both dominant and recessive genes for the two traits.
The allele combinations in the gametes it produces can be BBTT, BBTt, BBtt, BbTT, BbTt, Bbtt, bbTT, bbTt and bbtt .
I hope this answer helps.
 
        
                    
             
        
        
        
Answer:
Phanerozoic Eon is divided into three eras on the basis of prevailing climatic conditions on earth and dominant life forms present during the time. 
Explanation:
The Phanerozoic Eon is divided into three eras namely the Paleozoic, the Mesozoic, and the Cenozoic era. The basis for classification of the Phanerozoic eon into three eras are the prevailing climatic conditions on earth and dominant life forms present during the time. Changes in climatic conditions of earth altered the species composition and dominant life forms present in each era.
