Answer: D. Digestion increases as the volume of the enzyme increases.
Explanation:
Enzymes speed up reactions by reducing the activation time of a reaction. If there are more enzymes therefore, the reaction will move faster. 
Pepsin is an enzyme that prefers acidic conditions so it can work with dilute HCL. It can also work in temperatures of 40 °C without getting denatured. As more Pepsin is added therefore, the reaction will move faster and digestion will increase. 
 
        
             
        
        
        
Answer:
b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.
Explanation:
Ti-plasmid has the ability to introduce part of its DNA (t-DNA) into the genome of host plants. This is very important for the relationship of genetic manipulation in maize plants, with the aim of inducing a gene that promotes herbicide resistance. In addition, T-DNA has many genes that code for the production of plant growth phytohormones, which is extremely important for the cloning process to work. In this case, we can assume that the correct answer for yours is the letter B.
 
        
             
        
        
        
<span>heterozygous / homozygous refers to whether both alleles for a gene are the same. The organism is homozygous if both alleles are the same - that is, either both are dominant or both are recessive. The organism is heterozygous if the alleles are different - that is, if one allele is dominant and the other allele is recessive..

A. T-A-C-G-A-T
A and T pair together, and G and C pair together. There are no U’s because U’s are in RNA, not DNA.
