Question:
<em>The diagram shows the potential energy changes for a reaction pathway.</em>
Part 1: Does the diagram illustrate an endothermic or an exothermic reaction? Give reasons in support of your answer.
Part 2: Describe how you can determine the total change in enthalpy and activation energy from the diagram and if each is positive or negative.
Answer:
Part 1: The diagram illustrates an endothermic reaction as the products has a higher potential energy than the reactants do. There is a positive slope of the diagram and there is enough energy to meet the activation energy requirement.
Part 2: You can determine the total change in enthalpy and activation energy from the diagram by the potential energy of the reactants. If the reactants have a high potential energy, then the enthalpy is also high, and if the reactants have a low potential energy, then the enthalpy is low. You can determine if the diagram is positive or negative by knowing if its an endothermic or exothermic reaction. An endothermic reaction is positive because the products are higher than the reactants and a exothermic reaction is negative because the reactants are higher than the products.
The correct option is C.
Lantana is a tropical evergreen shrub which is usually cultivated as ornamental flowers. It is a plant that threatening livestock especially in Australia. The signs of lantana poisoning in livestock include: excessive skin sensitivity to sunlight, liver damage, yellow coloration of the white part of the eyes, reddening of the eyes, swelling of the ears, etc.
If the poisoning case is severe, the animal death will occur between two to four days, but generally, untreated animals usually die within one to three weeks.
True rib : the first seven ribs attach to the sternum (the breast bone) in the front and are known as true ribs (or sternal ribs)
False ribs: the lower five ribs do not directly connect to the sternum and are known as false ribs
Floating ribs :The floating ribs are less stable and risk breaking because they have only one attachment
Dorsally to the vertebrae and have very thin bone tissue locked in muscle as they extend
Laterally.
There is no picture of the bird.
In the plant, when a cell divides into two daughter cells, we observe in this experiment Mitosis, which is the cell division that allows the plant to elongate and occurs in the meristematic tissues that are at the ends of the plants. Whereas meiosis is restricted to reproductive tissue and forms gametes that will form new seeds through fertilization, carrying genes from one generation to another.
<h3>How does mitosis occur in plant cells?</h3>
In plant cells, division takes place from the inside out – centripetal cytokinesis. In plant cells, cytokinesis is centrifugal, from the outside to the inside: there is the formation of a lamella, which grows from the center to the periphery and separates the two cells.
With this information, we can conclude that through successive mitotic divisions that the zygote (cell generated after the meeting of gametes) manages to originate all the cells of its organism. Mitosis, therefore, is responsible for the growth and development of embryos.
