1.The nucleus<span> is the most </span>important<span> organelle in the </span>cell<span>. It contains the genetic material, the DNA, which is responsible for controlling and directing all the activities of the </span>cell<span>. 2. </span>Themembrane<span> keeps the </span>digestive<span> materials from leaking out into the cytoplasm and destroying the </span>cell<span>. Discuss how </span>cells<span>, tissues, organs, and organ systems are related. 3. </span>Cells<span>, </span>Tissues<span> and </span>Organs<span>. As we mentioned before, </span>cells<span> are the building blocks of life. When we have a group of </span>similar cells<span> working together this is called a </span>tissue.<span> 4. </span>Single-celled organisms<span> are made of only </span>one cell<span>. Multi-cellular </span>organisms<span>, such as plants and animals, have a higher degree of specialization where the </span>cells<span> work together and function to create a living </span>organism<span>. 5.</span><span>Structurally, </span>plant<span> and </span>animal cells<span> are very similar because they are both eukaryotic </span>cells<span>. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes.</span>
Answer: This is because animals (like humans) have more organelles to store in our bodies than bacteria. This makes sense because without all of our organelles we wouldn't be able to function properly. This is just another one of those form=function things.
Performance can be impaired by a fluid-related decrease in body weight of as little as 1 percent. Dehydration is assumed to be a major adverse effect associated with rapid loss of body mass and this impairs the level of performance in an individual.
