Answer:
In the New York Times article, "The Search for Life on Venus," by Kenneth Chang, the author explores the possibility of life on Venus, the second planet from the sun. In this article, Chang examines the various theories surrounding the possibility of life on Venus, including the potential for habitable clouds in the planet's atmosphere. He also discusses the potential for future exploration of Venus, including the possibility of sending a robotic spacecraft to the planet's surface.
Chang explains that the conditions on Venus are hostile to life, with temperatures reaching up to 860 degrees Fahrenheit and a crushing atmospheric pressure 90 times that of Earth's. However, the clouds of Venus may be a more hospitable environment, with temperatures ranging from 40 to 80 degrees Fahrenheit and a pressure closer to that of Earth's. This has led some scientists to speculate that microbial life may exist in these clouds.
In conclusion, Chang's article provides an interesting overview of the possibility of life on Venus. While the surface of Venus is too hostile for life, the clouds may provide an environment where life could exist. Future exploration of Venus may help to answer the question of whether life exists on the planet.

Which substances are needed for cellular respiration?
Use complete sentences to explain how the mass of hydrogen is conserved during cellular respiration. (10 points)
Chemical reactions that simulate cellular respiration follow the Law of Conservation of Matter when they are balanced. Six carbon atoms, 12 hydrogen atoms, and 18 oxygen atoms are the same number of atoms as the reactants. C₆H₁₂0₆+60₂ — 6C0₂+6H₂0 .
What is cellular respiration?Through the process of cellular respiration, organisms mix oxygen with food molecules, directing the chemical energy contained in these substances toward life-sustaining processes while excreting carbon dioxide and water as waste. Foods are broken down by organisms that do not require oxygen in a process known as fermentation.
What are atoms?A chemical element is uniquely defined by its atoms, which are small units of a substance. An atom is made up of a core nucleus and one or more negatively charged electrons that orbit it. The positively charged, comparatively hefty protons and neutrons that make up the nucleus may be present. The fundamental building components of matter are atoms. Atoms make up anything that has mass and occupies space.

Mass wasting is movement of rock and soil down the hill. The rocky hillside slopes can be secured by slope reinforcement. if the slopes are not stabilized, landslide can cause damage.
What do you mean by mass wasting?Mass wasting is the movement of rock and soil down slope under the influence of gravity. Rock falls, slumps, and debris flows are all examples of mass wasting. Often lubricated by rainfall or agitated by seismic activity.
The most common types of mass wasting are slumps, rockslides, debris flows, and earthflow. Slumps are slow and short-distance downslope movements of semi-consolidated earth material on a curved or planar sliding surface.
The most destructive type of mass movement is a landslide, which occurs when rock and soil slide quickly down a steep slope. Some landslides may contain huge masses of rock, while others may contain only a small amount of rock and soil.

What is the answer for Tia makes a model of a glacier with clay, sand, and an ice cube. She pushes the ice cube over the clay that is covered with sand. Explain how she could use the model to show that glaciers carry soil.
The model prepared by Tia could be used to show the glaciers which carry soil as similar to the clay which carries the ice cubes and sand, the glaciers also carry various materials along with them.
What are Glaciers?A glacier is a persistent body of dense ice and other materials that is constantly moving under its own weight and force. A glacier forms where the accumulation of snow exceeds the ablation over the period of many years, often centuries.
Glaciers acquire the distinguishing features, such as crevasses and seracs, as it slowly undergoes flow and deforms under the stresses which are induced by its own weight. As it moves constantly, it abrades rocks and debris from its substrate to create the major landforms such as cirques, moraines, or fjords. Although a glacier may flow into a waterbody, it forms only on the land surface and is distinct from that of much thinner sea ice and lake ice which form on the surface of bodies of water.

Answer:
The plant cell converts the most food into energy because it contains chloroplasts, which are organelles that are responsible for photosynthesis. Photosynthesis is the process in which plants use light energy from the sun to convert carbon dioxide and water into glucose. This glucose is then used as an energy source for the cell. The other cells do not contain chloroplasts and therefore cannot conduct photosynthesis, so they are not able to convert as much food into energy.
