Answer:
See the answer below
Explanation:
<em>Both conclusions can be valid because they are based on valid data and scientific reasoning.</em>
In order for a data to be valid in making a conclusion, such data must have been collected through a scientific experiment that is devoid of subjectivism. In order words, the data must have been objectively collected via standard experimental procedures.
Once data have been collected, they are analyzed and used to make valid conclusions based on the hypothesis which must have been made earlier before the experiment.
Conclusions made from standard experimental procedures and scientific reasonings are valid and such experiments are reproducible.
<em>Hence, as long as the data from which the conclusions were made can be reproduced through the same experiments, the conclusions are valid.</em>
Like a panic button, the amygdala issues an alert, summoning other parts of the brain that play a role in the experience of fear, one example would be your hypothalamus. Amygdala as stated is the center for emotions, emotional behavior and motivations.
This is a question regarding how enzymes increase the rates of reactions. There are choices and the instructions is to check all that apply.
<span>1. They shift the reaction equilibrium towards the products. </span>
<span>2. They increase the concentration of the reactants. </span>
<span>3. They lower the activation energy of the reaction. </span>
<span>4. They decrease the free energy of a reaction. </span>
<span>5. They promote the formation of a transition state.
The correct answers in this question are "they lower the activation energy of the reaction" and "they promote the formation of a transition state". Enzymes do not necessarily shift the the reaction equilibrium to the products, as there are reversible enzymatic reactions that can reverse the pathway back to the substrates. They do not increase the concentration of the reactants as the concentration of the reactants is an independent variable in this process. They do not decrease the free energy of activation as this is a constant in every reaction depending on the substrates and the products.
Enzymes do, however, lower the activation energy of the reaction meaning it will take less energy and effort for the substrates to reach the activation energy to transform it to its transition state then to the products. With this said, enzymes promote the formation of a transition state.

Answer:
Chemical properties of water are neutral pH and weak ionization while physical properties of water are that it is present in solid , liquid and gas form and it is a tasteless and odorless molecule.
Explanation:
Water is also called universal solvent due to its polar nature. Water has a neutral pH when it is present in pure form but with the addition of salts and other impurities, pH of water changes. Water has weak ionization rate. Water is present in liquid form at room temperature but increasing in temperature , they transform in gaseous state.. Water is a taste less molecule and having no odor or smell.
