guajiro [1.7K]

Answer:

Option C

Explanation:

Gastrocnemius and soleus muscles are jointly known as calf. Gastrocnemius is the larger muscle and connects to the knee joint while soleus is smaller muscle that connects to the portion of leg just below the knee. When gastrocnemius is stretched, the knee remains straight while when the soleus is stretched the knee bends. If a person feels difficulty in bending or stretching the knees, he/she must be facing the problem with the calf muscle. Hence, Option C is correct

Which diagrams shows reaction pathway that absorbs energy?
postnew [5]

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.

bixtya [17]

Answer:

Mechanical isolation

Explanation:

mechanical isolation is a form of prezygotic reproductive barrier, whereby similar species organisms become isolated and unable to successfully interbreed with each other to form zygote, as a result of incompatibility of their reproductive organ or structure, which prevents them from copulating. As a result of this, both species become separated as there is no gene flow between both.

The two species of juniper can be said to be kept separate by <em>mechanical isolation</em>, due to the differences and incompatibility of their reproductive structure.
