Explanation:

i had that question before:)

Answer:

Covalent bonding and Ionic bonding.

Covalent bonding is when atoms share electrons in order to form a stable electron arrangement. The two positive nuclei are attracted to the positive shared electron which holds the molecule together.

Ionic bonding is a giving and accepting of electrons between a metal and non metal. A metal will give the non-metal one or more electrons in order for both to form a stable electron arrangement.

False. Middle-range factors do not favor disruptive selection.

Disruptive selection occurs when extreme phenotypes are favored over the intermediate phenotype, leading to a bimodal distribution.

This means that individuals with traits on both ends of the spectrum have a selective advantage, while those with intermediate traits are at a disadvantage.

In the case of human birth weights, where the middle range is favored, it would be an example of stabilizing selection.

Stabilizing selection favors the intermediate phenotype and acts to reduce the variability in a population, maintaining the status quo.

Answer:

False

Explanation:

Answer:

B

Explanation:

High air pressure usually indicates dry weather conditions because It is harder for evaporation to occur and for clouds to form. Therefore, option B is correct.

High air pressure usually indicates dry weather conditions because it is associated with descending air, which suppresses cloud formation and precipitation.

When air pressure is high, it means that the weight of the atmosphere above a particular location is greater than usual. This causes the air to sink down toward the Earth's surface, which creates a stable atmosphere. As the air sinks, it becomes warmer and drier, which inhibits the formation of clouds and reduces the likelihood of precipitation.

Therefore, high air pressure is generally associated with stable, dry weather conditions. Thus, option B is correct.

Carbon , hence overcomes this difficulty by sharing its four valance electrons with other atoms of carbon or with atoms of other elements.

A valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed.

Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.

For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table.

When you inhale, oxygen enters your body through your nose and travels down the respiratory system, where it is taken up by the lungs. From there, the oxygen molecule moves into the circulatory system, where it travels through different organs and tissues to provide energy for your body's functions.

As the oxygen molecule moves through the circulatory system, it travels through the heart, where it is pumped into the arteries and distributed to the body's tissues. The oxygen molecule is then taken up by the red blood cells in your bloodstream, where it binds to hemoglobin.

Once the oxygen is bound to hemoglobin, it travels to the tissues that need it. In the tissues, the oxygen molecule is released from hemoglobin and diffuses into the cells, where it is used in cellular respiration to produce energy for the body's functions.

Fertilisers give crops vital nutrients like nitrogen so they may grow larger, more quickly, and yield more food.

However, using too much fertiliser can be harmful because it causes eutrophication and the emission of greenhouse gases.

Potassium (K)-rich fertilisers are regularly used to make up for plant deficiencies. Farmers must add this essential plant nutrient when soils are unable to provide crops with the K levels they require.When urea is added to the soil, it quickly turns into ammonium through a reaction with water and the soil enzyme urease.

The chemical reaction below illustrates this conversion, which is known as urea hydrolysis. The consumption of hydrogen ions (H+) in this reaction raises the pH of the soil close to the fertiliser.

None of the facts supports phrenology and pseudoscience the correct answer is none of the above, option e is correct.

Phrenology is considered a pseudoscience not because none of it is true, but because its fundamental principles and methods have been discredited and are not supported by scientific evidence. Phrenology was a popular belief in the 19th century that claimed personality traits and mental abilities could be determined by examining the shape and size of bumps on the skull.

However, modern scientific understanding of the brain has shown that specific mental functions are not localized to specific areas of the skull as suggested by phrenology. The reason phrenology is considered a pseudoscience is that it lacks empirical evidence and scientific validity. Its claims have not been supported by rigorous experimentation or replicated findings.

Windmill vanes or blades are designed to capture the wind by using the concept of lift and drag. The lift force is generated by the blades' design, which is similar to the wings of an airplane. This force is created as air flows over the blades, resulting in low-pressure air

on one side and high-pressure air on the other. As a result, the blades are pushed in the direction of low-pressure air, causing them to rotate. The blade's shape is critical in this process. Blades with a flat surface, for example, would generate very little lift and would be unable to turn. To generate lift, the blade's surface must be curved. The curved shape allows for a difference in air pressure between the top and bottom of the blade, generating lift as air flows over it.

To capture as much wind energy as possible, the blade's shape is designed to provide a balance between lift and drag. The drag force is caused by air resistance, and it opposes the forward motion of the blades. The perfect blade design maximizes lift while minimizing drag, allowing the blades to rotate more easily and capture more wind energy.To summarize, windmill blades are designed to capture wind by using the concepts of lift and drag. The curved shape of the blade generates lift as air flows over it, and the blade's design balances lift and drag to maximize wind energy capture. This is the main answer to how windmill vanes or blades are designed to capture wind.
