Explanation:
Hurricanes form over the warm ocean water of the tropics. When warm moist air over the water rises, it is replaced by cooler air. The cooler air will then warm and start to rise. This cycle causes huge storm clouds to form.
Hurricanes can be defined as a serious type of storm which forms over
tropical or subtropical waters.
Hurricanes typically forms in the warm ocean water of the tropical or
subtropical regions
Hurricane involves the warm moist air over the water rising due to
evaporation which is then replaced by cooler air. The cooler air then warms
up and start to rise and then the cycle continues. This continuous cycle
makes huge storm clouds to form.

The air pressure at City A is 1,018 mb, and the air pressure at City B is 980 mb. What will most likely occur due to the pressure gradient present between City A and City B?
Answer:
There are three main causes of change in population: births, deaths and imigration flow. The Coronavirus has affected two of these three factors. The death rate has increased substantially since the pandemic hit. In under 6 months, more than 200,000 people have died. This drastic number of deaths in such a short amount of time is bound to decrease the population of the United States by a considerable margin. Immigration flow has also halted since the beginning of the pandemic. Travel bans and the close monitoring of borders has ensured that the number of immigrants entering the United States has decresed greatly.
Most likely the pressure gradient present between City A and City B that is City A is 1,018 mb, and City B is 980 mb, will - The high-pressure system at City A will create winds that blow toward the low-pressure system at City B.
A force exerted on a surface by the air above it as gravity pulls it to Earth is called air pressure or atmospheric pressure. Atmospheric pressure is commonly measured with a barometer.
it determines wind and weather patterns across the globewinds move from high air pressure to low air pressureIt leads directly to wind and influences the speed and direction of that wind.Pressure differences or gradients also affect larger weather systems like storms.Thus, Most likely the pressure gradient present between City A and City B that is City A is 1,018 mb, and City B is 980 mb, will - The high-pressure system at City A will create winds that blow toward the low-pressure system at City B.

How are fossils that contain vestigial organs consistent with common ancestry?
Answer:
Explanation:
La evidencia de un antepasado común en los seres vivos, que han encontrado durante décadas científicos que trabajan en numerosos campos, demuestra la descendencia común de estos seres, que la vida en la Tierra se desarrolló a partir de un último antepasado universal, que la evolución existe y que puede demostrar los procesos naturales que han dado como resultado la biodiversidad de la vida en la Tierra. Esta evidencia apoya la síntesis evolutiva moderna, la actual teoría científica que explica cómo y por qué cambia la vida a lo largo del tiempo. Los biólogos evolucionistas han documentado evidencias de antepasados comunes realizando predicciones verificables, probando hipótesis y desarrollando teorías que ilustran y describen sus causas.
La comparación de secuencias genéticas de ADN ha revelado que los organismos filogenéticamente próximos tienen un mayor grado de similitud secuencial que los organismos filogenéticamente alejados. Se pueden encontrar más pruebas de la descendencia común en detritus genéticos como los pseudogenes, regiones del ADN ortólogas a un gen en un organismo relacionado, pero que ya no tienen actividad y parecen estar experimentando un proceso continuo de degeneración por acumulación de mutaciones.

How do you know this?
Answer:
detail is given below
Explanation:
We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus. Electron has a negative charge and is written as e⁻. Proton has positive charge P⁺ and neutron is neutral n⁰ .
The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons. The number of protons and electrons are always equal to make the atom electrically neutral and when an atom loses its valance electron the number of protons increases and thus positive charge increased and atom form cation.
Cation formation:
X → X⁺ + e⁻
When an atom gain electron negative charge increase because of more number of electron thus atom form negative ion or anion.
Anion formation:
X + e⁻ → X⁻
1) If an atom loses an electron, it becomes... (positive ion)
2) If an atom gains an electron, it becomes... (negative ion)
3) A hydrogen atom loses an electron. It becomes...(positive ion)
4) A sodium ion (Na) can ionically bond with which?
Sodium ion (Na⁺) can ionically bonded with Cl⁻ , thus both form salt which sodium chloride. Sodium ion can not bonded with hydrogen and potassium because both are also form cation.
5) If an atom gains or loses a neutron, the charge of that atom changes.
The given statement is false because neutron is neutral so when it added or removed from an atom there will be no effect on charge.
6. If an atom gains or loses an electron, the atomic mass of that atom changes.
The given statement is also false because atomic mass is sum of number of neutron and protons. So when electron is added or lost by an atom there will be no effect on atomic mass.
7. If an atom gains or loses a neutron, the atomic mass of that atom changes.
The given statement is true. Atomic mass is sum of number of neutron and protons. So when neutron is added or lost by an atom there will be effect on atomic mass. The atomic mass will be increase or decreased.
8. An atom with valence electrons can covalently bond with another atom.
The given statement is true. The valance electrons of an atom are involved in bonding. It could ionic, covalent or any other type.

Answer:
A well labelled diagram of a leaf structure
Explanation:
Answer:
Vascular bundles are a collection of tube-like tissues that flow through plants, transporting critical substances to various parts of the plant.The cuticle reduces the rate of water loss from the leaf surface.Stomata are tiny holes found in the underside of leaves. They control water loss and gas exchange by opening and closing. They allow water vapour and oxygen out of the leaf and carbon dioxide into the leaf.Which of the following is a way that the hummingbird shown is adapted to its environment and way of life?

What particles cannot pass through the cell membrane
Large molecules such as proteins and nucleic acids, charged particles (ions), and polar molecules such as glucose are examples of particles that cannot pass through cell membranes.
The lipid bilayer of the cell membrane makes it difficult for charged and polar substances to pass through. However, small, non-polar molecules and compounds that are lipid soluble can readily diffuse across the cell membrane. Aquaporins make it easier for water molecules to do this by facilitating osmosis.
The selective permeability of the cell membrane enables it to control the passage of molecules, preserving cellular harmony and functionality. In contrast, diffusion allows the easy passage of small, non-polar molecules such as oxygen, carbon dioxide, and lipid-soluble compounds through the cell membrane.

What hypothesis was validated by using paleo-magnetism?
Question 8 options:
a) subduction
b) hot spots
c) seafloor spreading
Answer:
C). Seafloor spreading.
Explanation:
Paleomagnetism is characterized as the 'study of the account of direction and strength of magnetic fields of the Earth in sediments, rocks, etc.' The hypothesis that was authenticated by using this study would be 'seafloor spreading' by displaying that magnetic reversal as strips of rotating polarity in gradually disseminating seafloor. This description of magnetic stripping by employing paleo-magnetism made the scientists believe that alternate crusts are being frequently made under ocean/sea. Thus, option C is the correct answer.

For which of the following reasons do small, isolated islands have a greater rate of
species extinction than larger, less isolated islands?
Answer:
Larger islands that are large and close to the mainland are shos lower rate of extinction due to the fact that the species present have more space so there will be more resources available in comparison to smaller islands where limited space and limited resources available.
Extinction is greater on islands isolated due to the unlikelihood of immigration and as it is opposite to the island close to the mainland and competition is more in isolated islands.
Lack of immigration, lower space and resources are the reasons small isolated islands have a greater rate of extinction.
Large islands have large space for the growth of an organism as well as more resources which lowers the competition between organisms while on the other hand, small islands have lower space for growth and low amount of resources which causes to more competition leads to greater rate of extinction so we can conclude that lack of immigration, lower space and resources are the factors that affect the rate of extinction.
