Answer:
The graph shows that the population of bacteria is increasing with the passage of time. During 1st hour, the population of bacteria is 50 per ml. In second hour, the population is doubled i. e. 100 per ml. In the 3rd hour, the population reaches to 200 per ml and in 3 and half hours, the population touches the value of 300 per ml. So the graph clearly shows that population is double with each hour. 
 
        
             
        
        
        
Answer:
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa.

Answer:
0.058 % kcalories comes from carbohydrate.
Explanation:
1 g of carbohydrtes gives 4 calories, 1 g of protein gives 4 kcalories, 1 gm of fat gives 9 calories and 1 g of alcohol gives 7 calories of energy. 
Thus in a meal  that contains 110 g carbohydrates gives 110 x 4 = 440 calories,  25 g protein gives 25 x 4 = 100 calories, 20 g fat gives 20 x 9 = 180 calories and 5 g alcohol gives 5 x 7 =  35 calories. 
Total calories in a meal  440+100+180+35 = 755.
Therefore % of carbogydrate will be 440x 100 divided by 755 = 58.27 %
In kcalories % would be 58.27/1000 = 0.5827 %
