Human caused climate change (most notably, global warming) has many positive feedback loops intrinsic to itself. Please describe at least one of these loops and explain how it is potentially dangerous for habitability of the earth.
Answers
When we burn fossil fuels to produce electricity, heat, and more, they emit greenhouse gases (GHGs) like carbon dioxide (CO2) and methane. These gases trap the sun’s energy in Earth’s atmosphere as heat. As more and more GHGs are released, more heat gets trapped and the planet warms up, disrupting the long-standing, delicate climate systems that have made life on Earth possible.
The stronger storms and longer droughts we see becoming a dangerous new normal are a direct result. But how these impacts play off each other is far more nuanced. In many cases, the wildfires or disappearing glaciers we see in the headlines have unseen knock-on effects that lead to, well, more wildfires and disappearing glaciers.

Although compound microscopes and electron microscopes have some similarities, only _____________ microscopes use light and lenses to magnify objects.
please help me
Answers
Answer:
ORDINARY LIGHT
Explanation:
Compound microscopes and electron microscopes have some similarities only light microscopes use light and lenses to magnify objects.
What are light microscopes?A light microscope is an apparatus or tool used in biology labs that employ visible light to find, magnify, and enlarge very minute things. Utilizing lenses, they concentrate light on the specimen, magnifying it to create a picture. In most cases, the specimen is positioned near the tiny lens. The types and quantity of lenses that make up the microscope have a significant impact on the microscopic magnification.
There are two types of microscopes based on the number of lenses used: simple light microscopes, which have low magnification due to the use of a single lens, and compound light microscopes, which have higher magnification than simple light microscopes due to the use of at least two sets of lenses an objective lens and an eyepiece.
The lenses are positioned such that they may bend light for effective picture magnification.
The light microscope's capacity to make a picture by focusing a beam of light through a tiny, transparent object is the foundation for how it works. The picture is then magnified for viewing through one or more lenses. The specimen's transparency makes it simple and quick for light to enter. Bacteria, cells, and other microbial particles can all be included in specimens.
Therefore, although compound microscopes and electron microscopes have some similarities only light microscopes use light and lenses to magnify objects.

Two key processes by which organisms produce water are photosynthesis and cellular respiration.
The method that plants employ to produce their own nourishment is called photosynthesis. Plants absorb carbon dioxide from the atmosphere and utilize the sun's energy to transform it into glucose. One kind of sugar that plants need for energy is glucose. Additionally, plants emit water vapor into the atmosphere as part of the photosynthetic process. The method through which organisms get energy from the food they consume is known as respiration. When creatures consume food, the glucose molecules in their cells are broken down, releasing the energy they contain. Water vapor is also produced during this process and is discharged into the atmosphere.
Eventually, the water vapor produced by respiration and photosynthesis condenses and returns to Earth as rain. The cycle is restarted when this rainfall ultimately finds its way back to the oceans.
Therefore, by the process of photosynthesis and cellular respiration, organisms use carbon based molecules to make water.
