When water solidifies to ice its volume increases keeping the mass same and therefore the density decreases.
What is solidification process?
Atoms are transformed from a liquid, disordered state through the process of solidification into an ordered solid state. By adhering to the kinetic principles, the conversion rate for the solidification process can be attained.The unique structure of a water molecule is made up of one oxygen atom and two hydrogen atoms. The peculiar arrangement of these atoms gives water certain unusual features, including its high thermal conductivity, surface tension, adhesion, and cohesion.When water freezes, the molecules get organized into a crystalline structure and take on a certain shape. Since there are spaces between individual molecules in this less dense crystalline structure, water expands as the volume of the structure as a whole rises.Ice forms as water expands, and because volume is inversely proportional to density, ice is less dense than water. This is the reason why ice, which feels heavier in its solid state than in its liquid one, floats on water.
Thus when water changes to ice its volume increases and density decreases.

O A. Temperate deciduous forest communities
OB. Tropical rain forest communities
OC. Deep ocean communities
O D. High mountain communities

What is climate change?
Long-term altercations in weather and temperature patterns are referred to as climate change. These changes might occur naturally, for instance through variations in the solar cycle. But since the 1800s, burning fossil fuels like coal, oil, and gas has been the primary cause of climate change, which is mostly attributable to human activity.By trapping the sun's heat and increasing the temperatures, greenhouse gas emissions mostly produced by burning fossil fuels behave as a blanket over the planet.Methane and carbon dioxide are two examples of the greenhouse gases that are contributing to climate change. These result from using fuels like gasoline or coal to heat buildings, respectively. Carbon dioxide can also be released during logging and clearing land. Methane emissions are primarily produced by landfills for trash.According to the Intergovernmental Panel on Climate Change (IPCC), global warming is responsible for a number of extreme impact events, making mountain ecosystems particularly vulnerable to climate change.
As glaciers continue to recede, less water is available, which causes more erosion and landslides in mountainous regions. High mountains are considered "particularly temperature-sensitive locations," and there is data to suggest that temperatures are increasing more quickly at higher elevations.

Based on the reactivity of li, na and k. Predict the behavior of rb and cs. Why would we not do these experiments in the freshman chemistry labs?.
Rubidium and caesium are less reactive in comparison to Lithium Sodium and potassium. These experiment should not be performed in freshmen Chemistry lab because Lithium Sodium and potassium are highly reactive elements.
The same group contains the elements lithium, sodium, potassium, rubidium, and cesium. These are all components in group 1.
When we move from top to bottom in the group, lithium is at the top and caesium is at the bottom. The element becomes less reactive. The ionization energy drops, which causes a drop in reactivity.
From top to bottom in the group, the element's size grows. The element becomes less reactive as a result of its larger size since the ionization enthalpy is decreased. Due to the three compounds' extreme reactivity—lithium, sodium, and potassium—when they are left open, they react even with air, making them inappropriate for use in freshman chemistry laboratories.

happens when humans greatly accelerate the input of plant nutrients to a lake. group of answer choices cultural eutrophication erosion popular eutrophication oligotrophic water pollution
Cultural eutrophication happens when humans greatly accelerate the input of plant nutrients to a lake.
Human activities can significantly speed up the inflow of plant nutrients into a lake when it’s close to an urban or agricultural region, a process referred to as cultural eutrophication.
What about eutrophication?The natural action of eutrophication is brought on by the buildup of nutrients in lakes and other bodies of water. Nutrient-feeding algae develop to become ugly on the water's surface, reducing its value for enjoyment and blocking water intake pipes. The process of eutrophication, which happens when the environment becomes enriched with nutrients, increases the number of plant and algae development in estuaries and coastal waters, is what causes harmful algal blooms, dead zones, and fish kills. Since eutrophication frequently results in the degradation of water quality and the reduction of dissolved oxygen in water bodies, it’s seen as a severe environmental concern. Eutrophic waters have the potential to eventually become"dead zones" that cannot sustain life. Cultural eutrophication has been linked to hypoxia, blue-green algal blooms, polluted beverage sources, and a decline in recreational options. A process referred to as eutrophication is brought on by an excess of nutrients, primarily nitrogen and phosphorus, in water. Algae thrive, spread, and color the water green as a result of feeding on the nutrients. Eutrophication are often reduced by controlling the nutrient sources, curtailing fertilizer use, using good soil management techniques, putting mathematical models to use, adopting phytoremediation, etc. Among these, raising general knowledge of eutrophication can help prevent it from happening to water bodies.Learn more about eutrophication here:

describe the structure of a molecule of hemoglobin and explain the role played by iron in the transport of oxygen.
Hemoglobin's structure has four heme groups, each has an iron molecule within the center used to bind and carry oxygen throughout the body.
The delivery of oxygen to the blood is one among iron's most significant roles. The first function of iron is to transport oxygen throughout your body in the hemoglobin of red blood cells so that your cells can make energy. Additionally, iron enhances myoglobin's capacity to store oxygen.
What about hemoglobin?Red blood cells include the protein hemoglobin, which transports oxygen to your body's organs and tissues and carbon dioxide from those tissues back to your lungs. You have a low red blood cell count if a hemoglobin test reveals that your hemoglobin level is lower than normal.When you have anemia, your body doesn't produce enough healthy red blood cells to provide your tissues with enough oxygen. Being anemic, or having low hemoglobin, can cause you to feel exhausted and frail. Anemia can have many various forms, each with a singular etiology. Your blood's hemoglobin helps carry oxygen from your lungs to your tissues. In muscle cells, myoglobin receives, transports, stores, and releases oxygen. By making dietary modifications and using supplements, many of us can increase their hemoglobin levels. To establish the proper supplement dosage, consult a physician. An individual might require additional therapy,like a blood transfusion, if their hemoglobin levels are still low. Your illness or injury is causing blood loss.

4. Light hits PS2 and pigment molecule absorbs energy and gets excited to release electron. The electron is taken by the primary electron acceptor. Enzyme separates water into H+ (the two electrons) and O-, and supplies p680 with the electrons (strong oxidising agent). H+ is discharged into the thylakoid space, and oxygen from a split water molecule joins with another oxygen to produce O2.Photoexcited electrons travel from PS2 to PS1 through ETC. In PS1, electrons move to a lower energy level, supplying ATP with energy. As they descend, their energy pumps H+ into the chemiosis-related thylakoid luman. The electron in PS1 reaction complex P700 is excited by light energy that has been transferred there. After the electron passes through a second ETC, NADP+ reductase adds an electron, converting NADP+ into NADPH.
