- During a race such as a marathon, the skeletal muscle cells in your legs use a lot of energy to continually contract and power your muscles. What organelle is most likely abundant in skeletal muscle cells? mitochondria rough endoplasmic reticulum smooth endoplasmic reticulum Golgi apparatus
- Climate Impacts on Plant Evolution Earth's climate is changing. How might changes in climate impact plant evolution? Scientists hope to lind an answer to this question by looking into the past. Scientists compare fossils to modern plants. They gather clues to how Earth's plant life evolved as its climate changed. Modern plants that live in tropical climates usually have broad leaves. Those in cooler, drier climates have smaller leaves. By looking for similar patterns in fossil leaves, scientists can piece together how plants evolved as Earth's climate changed is millions of years ago Then they make predictions about what is happening to plants now and in the future. Scientists know that increased carbon dioxide levels in the atmosphere can increase photosynthesis For some plants, this growth. This may seem nthesis od thing. However, more growth also requires the use of more water This additional stress on water supplies. Also, some ecosystem are already dry because of climate-change temperatures can decrease the rate of nitrogen fixation to essential to that nitrogen fixation by plants Scientists webs plant evolution. Write About It How do scientists use what they have learned about past plant past plant __

- Functions of the smooth endoplasmic reticulum include __ lipid synthesis, steroid synthesis, and storage of genetic information steroid synthesis, protein synthesis, and drug detoxification lipid synthesis, protein synthesis, and drug detoxification lipid synthesis, steroid synthesis, and drug detoxification
