Answer:
The <em>answer </em>is option A i.e "32%". According to Chargraff's rule, Number of purine (adenine+guanine) = Number of pyrimidine (cytosine+thymine). Hence, the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
Hitchhicker's thumb is a condition in which a person is able to bend his thumb backwards. This trait can be seen in many people but the condition is recessive, which means a person needs two alleles for hitchhiker's thumb to have this particular characteristics. The gene for straight thumb is commonly indicated by T while that for hitch hicker's thumb is indicated by t.
Let's see what will happen if a person heterozygous for hitchhiker's thumb marries a woman who is also heterozygous for hitchhiker's thumb.
P1: Tt X Tt
Gametes: t T : t T
Offsping : TT : Tt : tT : tt
TT : 25 % : Straight thumb
Tt + tT : 50% : Straight thumb
tt : 25% : Hitch hicker's thumb
Therefore, there are 25 % chances that their offspring will have Hitch hicker's thumb and 75 % chances that they will have straight thumb.
Hope it help!
Answer:
cellular respiration in photosynthesis are biological processes in which matter and energy flow through the biosphere. These two processes are responsible for the exchange of oxygen and carbon dioxide between living organisms and the environment. Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a byproduct. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.
