Answer: 
You have 20% of adenine. If you have 20% of adenine than you have 20% of thymine, because the amount of adenine and thymine is equal. 20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal in the DNA stand.

Inputs of Cellular respiration are <span>Oxygen (6O</span>₂)<span> and Glucose (C</span>₆<span>H</span>₁₂<span>O</span>₆)<span>
Outputs of Cellular respiration are </span><span>Carbon Dioxide, water, ATP or energy
The main purpose of cellular respiration is to produce ATP. It takes place in the mitochondria.
ATP is the energy of the cells so that it can properly functions inside the body.

note:
Gymnosperms possess several key evolutionary innovations compared to earlier groups such as the clubmosses and ferns. They produce sperm-containing pollen, which is carried through the air by the wind to the female. This innovation has freed these plants from the need for water for sexual reproduction.
 
        
                    
             
        
        
        
Answer:
A :an atom seeks to fill its outer shell of electrons
Explanation:
Reactions between atoms occur due the desire of an atom to fill their outer shell electrons. 
The driving force for many interatomic bonding is the tendency to have completely filled outer energy levels like those of the noble gases. 
- The various interatomic interaction which leads to chemical reaction is in a bid for the atoms to be isoelectronic in the outer energy level with the noble gases. 
- This is achieved by gaining, losing or sharing of electrons. 
 
        
             
        
        
        
Answer:
Unformed hyphae are called yeast – a substance that is very useful and applicable in many industries and fields. On the other hand, mycelium (plural form – mycelia) is the vegetative part of the fungus. In relation to the hyphae, it is the network collection or bundle of hyphae in one single place
