Based on the graph above, how well will the enzyme perform as a catalyst when placed in a pH 7 solution, such as water?
mrs_skeptik [129]
The correct answer is "<span>It will perform less than optimally unless the pH was increased."

This is because the curve on the graph shows pH versus reaction rate. If we follow the x-axis (the bottom one) to a pH of 7, it is at an extremely low reaction rate compared to other points of the graph. If we continue along, we see that the reaction rate increases as the pH increases. Therefore, the enzyme will perform less than optimally unless the pH is increased.

Hope this helps, and hope I'm the brainiest! :)</span>

Explain how it is possible for nutrients to be transported to the cells of a flatworm with no circulatory system.
Alisiya [41]

Answer:

Flatworms are beings that do not have a heart, veins, arteries, capillaries, hemolymph, or some type of circulatory fluid. Their circulation occurs between cells or intercellularly and they are responsible for transporting substances by diffusion from cell to cell.

Explanation:

Flatworms are considered multicellular eukaryotic organisms. This implies that in their cells they have a cellular nucleus, in which the DNA is contained, structuring the chromosomes. Likewise, they are made up of several types of cells, each one specialized in a specific function. They lack a structured circulatory system as such. Because of this they do not have specialized structures such as a heart or blood vessels, however, the circulation of certain substances is established between their cells. This is done thanks to the diffusion process. Substances pass from one cell to another through this process.This does not apply to all flatworms, since in some species of bog and digenae there is a certain organization and some very small conducting vessels known as the endolymphatic system, the which forms a kind of plexus in the parenchyma.It should also be noted that some species do not even have a digestive system, being the digestive tract the one in charge of digestive functions and the distribution of the nutrients they receive.

AlekseyPX

Answer:

the smell or taste of chicken salad

Explanation:

  • A conditioned stimulus is the one which was previously a neutral stimulus but hen it gets paired with the unconditioned stimulus it leads to a conditioned response.
  • The learned response which is produced in response to a neutral stimulus is the conditioned response.
  • In the given condition the smell or taste of a chicken salad causes Allison to feel nauseated and hence, the taste or smell of a chicken salad is the conditioned stimulus which generates a conditioned response which in this case is nausea.

Answer:

The Calvin cycle is a process that plants and algae use to turn carbon dioxide from the air into sugar, the food autotrophs need to grow.

Every living thing on Earth depends on the Calvin cycle. Plants depend on the Calvin cycle for energy and food. Other organisms, including herbivores, also depend on it indirectly because they depend on plants for food. Even organisms that eat other organisms, such as carnivores, depend on the Calvin cycle. Without it, they wouldn't have the food, energy, and nutrients they need to survive.

The Calvin cycle has four main steps: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase. Energy to fuel chemical reactions in this sugar-generating process is provided by ATP and NADPH, chemical compounds which contain the energy plants have captured from sunlight.
