Answer:
Phenotypes
Explanation:
If a trait is simply controlled by 2 alleles, there is a maximum of three phenotypes that can be produced from the alleles. Either the individual is homozygous dominant (AA), homozygous recessive (aa), or heterozygous (Aa). This would give a maximum of 3 different phenotypes, potentially only 2 phenotypes if the trait is completely dominant
In contrast, if a trait is controlled by lots of alleles (either at the same gene or different genes) there are many more possibilities for the final phenotype, as each allele might contribute something slightly different.
Answer:
Although you have not put the answer options, the movement of the plates in the situation shown above occurs with the approach of their continental plates that collide and bend due to the impact.
Explanation:
The converging movement of the plates indicates that two plates are moving towards each other until they collide. When these two plates are continental, the movement is called continental-continental convergent.
As the two continental plates have the same density, the impact between the two causes them to bend and not sink into each other.
Answer:
The term “epigenetics” was introduced in 1942 by embryologist Conrad Waddington, who, relating it to the 17th century concept of “epigenesis”, defined it as the complex of developmental processes between the genotype and phenotype.
Explanation:
The four effects of Global Warming are mentioned above. But there are also many effects of Global Warming.
Answer: D. reduces the activation energy for the reaction it catalyzes.
Explanation:
The enzyme amylase is the enzyme which functions optimally in the environment. The enzyme amylase in the saliva functions in break down of starch which is a polysaccharide into small sugars. In this situation, the amylase is the enzyme and the starch is the substrate also the small sugar molecules are the products.
When the enzyme amylase binds to the substrate, then enzyme-substrate complex forms. The formation of this complex lowers the activation energy of the reaction and promotes the rapid progression of the reaction.
