Answer:
incorrect
Explanation:
diffusion is the movement of particles <u>with</u> the concentration gradient
for example: over time, food coloring and water mix and become one same color.
Answer:
<em>The correct options are</em>
<em> B) If the sources used are peer reviewed</em>
<em>D) If the writing is based on sound evidence</em>
Explanation:
To check whether a scientific report is valid or not, one must determine whether the results deduced from its experiments were accurate and true or not. If the writing provides sound evidence for its experiments to be true and not biased, then the editor will most likely publish it. A report that is supported by peer reviews will be the best to publish as the data in it will be considered to be more authentic and accurate. Hence, option B and D will be true.
This hydrocarbon because it possess at least 1 double bond it would be an Alkene. Alkenes possess at least 1 carbon carbon double bond. It is an example of an unsaturated hydrocarbon.
Based on the investigation, the inference that can be made about the result is that catalase activity increases with warm temperature.
The liver usually contains an enzyme known as catalase that is capable of breaking down hydrogen peroxide into water and oxygen gas. The bubbles observed in the beaker during the investigation represent the oxygen being evolved from the breakdown of the hydrogen peroxide by the catalase in the liver sample.
At room temperature, a moderate number of oxygen bubbles were observed. The number of bubbles increased with increased temperature as a result of placing the beaker in a warm water bath. At a lower temperature brought by placing the beaker in an ice water bath, no bubbles were observed.
Thus, we can effectively conclude that the activities of the catalase enzyme in the liver increased with a moderately increased temperature.

The correct answer is T helper cells. <span>T helper cells are important because they have the ability to stimulate other cells to kill the foreign particles (viruses, bacteria, fungi, parasites).T helper cells help other cells in the immune response by recognizing foreign antigens and by secreting cytokines that then activate T and B cells.</span>
