B - Enzymes act as catalysts because they lower the activation energy
Mesophyll cell
Below it is the stomata
And to the right its the vascular system that includes xylem and phloem.
Answer:
directional selection
Explanation:
The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. <em>Biston betularia</em>, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.
A. Enzymes, We have an enzyme in the cells in our bodies where hydrogen peroxide is converted.
1. our bodies convert chemical energy into electrical energy by moving.
sorry i could only find one.
