Answer:species that colonize new surfaces

Explanation: pioneer species are species that first colonize an environment It could be a barren land or a distrupt land that has been abandoned for a long time. some of the environment or soil are usually poor and plants found around such areas have long root and hard to adapt to the environment. Pioneer plant forms the basis of diversity and the initial stage of sucession. Example includes Algae,mosses

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.

Explain the effects of osmosis on cells and tissues:

viva [34]

Answer:

In explanation.

Explanation:

Effect of osmosis on cells:

-Osmosis is the movement of water across a cell membrane. Cells use osmosis to maintain concentration equilibrium (the concentrations of solute inside and outside the cell are equal). Changing the amount of water allows the cells to achieve equilibrium.

Effects of osmosis on tissues:

-Red blood cells placed in a solution with a higher water concentration compared to their contents (eg pure water) will gain water by osmosis, swell up, and burst. Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.

Hope this helps.
