My answer will be that the valence of the Carbon atom is (+4) and that of each Oxygen atom is (-2). The CO2 molecule is formed by covalent bonds, in other words: C (+4) + O2 (-4) = 0.

Sublimation is the process in which a solid directly transitions into the gaseous phase without going through the liquid phase. If sublimation didn't occur, solids would have to undergo melting and then evaporation to turn into gas.

Sublimation is the process in which a solid directly transitions into the gaseous phase without going through the liquid phase. If sublimation didn't occur, solids would have to undergo melting and then evaporation to turn into gas. Examples of sublimation include how snow disappears without melting or how dry ice turns into gas without forming a liquid. Sublimation is important in various applications such as air fresheners and cooling with dry ice.

Sublimation is a phase transition in which a substance transitions directly from a solid to a gas without passing through the liquid phase. It occurs when the substance's vapor pressure exceeds atmospheric pressure at a specific temperature. Dry ice (solid carbon dioxide) sublimates, creating the effect of "smoke" in theatrical productions and refrigeration.

If sublimation didn't occur, it would disrupt purification methods, chemical processes, material properties, and the water cycle, necessitating alternative approaches and potentially causing significant changes in various domains.

If sublimation didn't occur, several significant consequences would arise depending on the specific substances involved:

1. Loss of certain purification methods: Sublimation is a purification process for certain substances, such as iodine and dry ice (solid carbon dioxide). Without sublimation, alternative purification methods would need to be developed, which might be less efficient or more expensive.

2. Changes in certain chemical processes: Sublimation is involved in various chemical processes, such as the purification of substances, the deposition of thin films in manufacturing, and the creation of pharmaceutical products. Without sublimation, these processes would need to be reevaluated and potentially redesigned.

3. Alteration of material properties: Sublimation affects the properties of materials. For example, the ability of certain substances to sublime at low temperatures makes them useful in applications like air fresheners and mothballs. Without sublimation, alternative materials or methods would need to be used.

4. Impacts on the environment: Sublimation plays a role in the water cycle, where solid water (snow and ice) sublimes directly to water vapor. Without this process, the water cycle might be altered, potentially affecting weather patterns and ecosystems.

Overall, the absence of sublimation would disrupt various industrial processes, material properties, and natural phenomena, requiring adaptations and potentially leading to significant changes in multiple domains.

A nonmetal (or non-metal) is a biochemical component that frequently requires metallic characteristics. Materially, nonmetals tend to have moderately low melting and boiling points, and densities, are essentially inelastic if solid.

When a nonmetal bonds with a nonmetal the result is a covalent bond. A covalent bond is a chemical bond which includes the sharing of electron pairs among atoms. Water (H2O) and carbon dioxide (CO2) are examples of covalent bonds. In H2O, one oxygen atom joins with two hydrogen atoms.  

However they are habitually poor conductors of heat and electricity chemically, they manage to have approximately powerful ionization energy, electron relationship, and electronegativity charges.

Nuclear energy is the alternative energy source least dependent upon weather, providing consistent, reliable power independent of external conditions. Geothermal energy also has low weather dependence but nuclear typically has higher capacity and broader implementation.

The alternative energy source expected to be the least dependent upon the weather would be nuclear energy. Unlike solar and wind energy, which are subject to the whims of weather patterns and daylight hours, nuclear power does not depend on external weather conditions. Nuclear reactors can produce electricity continuously and are considered baseload power sources due to their ability to consistently supply power without interruption. While natural disasters can pose risks to nuclear power plants, the actual operation of a nuclear plant and its energy output are not typically affected by day-to-day weather.

Geothermal energy is another alternative energy source with low dependence on weather. It harnesses heat from within the Earth, which is both abundant and constant, meaning geothermal power plants can operate all year round without significant impact from weather conditions.

Therefore, comparing the two, nuclear energy would generally be less affected by the weather compared to even geothermal energy, because while both are non-intermittent, nuclear plants are often built to a capacity that can far exceed the energy generation of geothermal plants and are more widespread as a global energy source.

I would say A, B D are the correct answers

AB and D are the correct answers not C

The answer is C, destruction of the rainforest.

Answer:

Option (C)

Explanation:

The corals are directly affected due to the destruction of the rainforest.

Over the last few million years, the corals have grown as well as destroyed. They also resulted in the damages and occurrence of various changes in the corals.

When the forest areas were destroyed and lost, the soil particles are washed away into the rivers and streams, carrying all its essential minerals. These minerals are then transported to the seas and oceans. This presence of minerals in excessive amount causes negative effect on the growth of corals. In addition to this, when these large amount of eroded materials are added to the ocean, it forms a cloud, as a result of which the sunlight cannot penetrate into the zone where corals are abundantly present.

Thus, the destruction of rainforest caused various changes in the corals reefs.

Hence, the correct answer is option (C).

Answer:

C) If the liver is placed in an acidic solution, then the reaction rate will decrease.

Explanation:

Placing the pH in an acidic solution will cause denaturing of the enzyme catalase. Catalase is an enzyme which is in our liver and it breaks hydrogen peroxide into water and oxygen so as to protect our body from harmful effects of hydrogen peroxide. Catalase works best at 7 pH value. If we will place the liver in acidic solution it will cause denaturation of catalase. Denaturation alters the shape of the active site of enzymes. Active sites are the sites in enzymes which are meant for substrate binding. They have a shape which fits a specific substrate. So, if the shape of the active site will change due to denaturation, the substrate will no longer be able to fit into the enzyme and therefore reaction will not take place.

A growing animal obtains the calcium needed for new bone tissue predominantly through the consumption of calcium-rich foods. Other methods such as removing calcium from its own bones or the air, or making calcium from other elements are not viable ways for most animal species.

An increasing animal can acquire calcium, a critical element for the growth of their bones, primarily through the consumption of food that contains calcium. This is option C in the provided choices. When a growing animal, such as a puppy, ingests calcium-rich foods like milk or bone meal, its body can absorb the calcium and incorporate it into the new bone tissue that it's forming. This process allows for growth and development of the skeleton as the animal matures.

Bone formation is a complex process that requires adequate nutrients, of which calcium is very essential. Other mechanisms mentioned in the options, like removing calcium from its own bones (option A), manufacturing calcium from other elements (option B), or removing calcium from the air (option D) are not viable for obtaining calcium in most animal species.

Observing the embryos shown in the diagram can determine that the organisms share a common ancestor. (Option A).

The diagram of the embryonic stage of two organisms can help determine that the organisms share a common ancestor. This is because embryonic similarities between unrelated species are often preserved, while differences become more pronounced in adults.

For example, all vertebrate embryos have gill slits and tails at some point in their early development, which disappear in adults of terrestrial groups but are maintained in adult forms of aquatic groups such as fish and some amphibians.

Answer - Sub-Saharan Africa

P.S. Next time when you post a question please make sure to include all the given information in the question.

Hope This Helps :)

Final answer:

The largest number of child deaths in low-income countries is caused by pneumonia, diarrhea, and malaria. These are often linked with environmental factors like indoor air pollution, poor water quality, and malnutrition, and are preventable with better healthcare and sanitation practices.

Explanation:

According to the World Health Organization, the most frequent causes of death for children under five in low-income countries include pneumonia, diarrhea, congenital anomalies, preterm birth complications, birth asphyxia/trauma, and malaria. A significant number of these deaths can be prevented with interventions like immunizations, proper nutrition, access to safe water and food, and quality healthcare. The largest number of child deaths occurs due to environmental factors such as indoor air pollution from unprocessed solid fuels used for cooking and heating, poor water quality, sanitation, and hygiene that lead to diarrheal diseases, and infectious diseases like malaria, which is particularly prevalent in the African region. Malnutrition considerably contributes to child mortality and is often linked with environmental conditions. Due to the scarce healthcare resources in low-income countries, there is an urgent need for improved medical access to reduce these preventable deaths.

The mitotic process involves several stages, including the Interphase, Prophase, Metaphase, Anaphase, and Telophase, with each stage characterized by different processes involving genetic material and chromosomes.

The mitosis process involves several phases. Phase 1, Interphase, is when the genetic material is duplicated in the cell. Second phase is Prophase, where the chromosomes become visible and the spindle apparatus forms. During the third phase, known as Metaphase, the chromosomes line up in the middle of the cell.

Fourth phase is Anaphase is when chromosomes move to opposite ends of the cell. Lastly, in the Telophase phase, the cell plate forms and the nuclear envelope is reformed.

Answer: A sedimentary process

Answer:

Option (C)

Explanation:

The magma when it comes out to the surface from the greater depth, the magma gets crystallized having the gold in it. These rocks sometimes alter into metamorphic rock due to the extreme pressure-temperature condition. These rocks are affected by the water as it flows over them and over a due course of time, it weathers and erodes the minerals and is carried to some other place. This process of erosion and deposition of minerals is known as the placer deposits.

Thus, Gold is one type of mineral that is distributed by this type of sedimentary process.

Hence, the correct answer is option (C).

Answer: The correct answer is- Oxygen is released as a gas after water is split.

Photosynthesis is a process by which green plants and animals synthesize their own food using CO₂ ( carbon dioxide) and H₂O ( water) in the presence of sunlight. It is divided into two phases that is light dependent ( occurs in thylakoid membrane of chloroplast) and light independent phase ( occurs in stroma of chloroplast)

In the first phase, energy from sunlight gets converted to chemical energy that is ATP and NADPH and water is splitted into electrons, protons and molecular oxygen. This occurs at PS II ( photosystem II), which is a structure present in the thylakoid membrane of chloroplast. The electrons released then participate in the electron transport chain.

Molecular oxygen is released in the atmosphere.

The correct answer is option B, mineral composition

Gneiss is made up of medium to coarse grains and is a semischistose metamorphic rock. Its consists of quartz and feldspar,  biotite, hornblende, garnet or graphite. Being formed under high temperature and pressure, gneiss can only be weathered through chemical processes. The quick chemical weathering usually happens when the grains are small in size but in case of gneiss grains being large in size are difficult to be weathered.

The property of the gneiss sample that likely prevented it from weathering is its mineral composition.

The resistance of gneiss to weathering is partly due to its mineral composition, which usually consists of mica, feldspar, and quartz. Because these minerals are strong and chemically stable, weathering forces like wind, water, and temperature fluctuations are less likely to break them down.

Over time, their ability to withstand both chemical and physical changes contributes to the preservation of the gneiss rock's integrity by averting major weathering. Because of this, gneiss is a long-lasting and resilient rock type that keeps its structure and appearance across a variety of weathering processes.

Nuclear fusion reaction

Explanation:

The nuclear fusion process refers to the condition when two nuclei of smaller atoms are combined with one another to form a heavy nucleus, resulting in a large amount of energy.

This process takes place extensively in the core of the sun that helps the sun in burning, releasing a significant amount of heat energy.

This fusion reaction emits photons of higher energy, which are commonly known as the gamma rays, and it subsequently travels through the radiative layer of the sun that surrounds its core.

The reaction of nuclear fusion thereby results in the conversion of hydrogen into helium as well as helps in the conversion of mass into energy.
