Over-fishing is a threat to biodiversity resulting from human impact, specifically through unsustainable resource exploitation. Thus option C) 'Human Impact' is correct.
The correct answer to the question is Human Impact.
Over-fishing is a form of overexploitation, which is one of the main threats to biodiversity resulting from human activity. Over-fishing depletes fish populations faster than they can reproduce, leading to a reduction in biodiversity and the disruption of marine ecosystems.While global climate change and habitat loss are significant threats to biodiversity, they are typically not the direct result of over-fishing. Instead, over-fishing directly exemplifies how human impact on the environment can lead to unsustainable resource use and endanger species.
Complete question: Which of the following threats to biodiversity is a result of over-fishing?
A)Global Climate Change
B)Habitat Loss
C)Human Impact
D)Invasive Species
Correct option: C) Human impact
Atoms sometimes form bonds to
A. Lose energy
B. Become more stable
C. Give away neutrons
D. Give away protons
Atoms sometimes form bonds to become more stable. Option B is correct.
The stability of atoms is determined by the arrangement and distribution of electrons in their energy levels or electron shells. Atoms tend to have the most stable configuration when their outermost electron shell is filled with electrons, either by gaining, losing, or sharing electrons with other atoms.
In the process of bond formation, atoms interact with each other and undergo a redistribution of electrons. This redistribution allows atoms to achieve a more favorable electron configuration, often resembling that of a noble gas with a full outer electron shell.
By forming chemical bonds, atoms can fill or empty their outermost electron shells, which increases the stability of the entire system. The resulting stability is driven by the decrease in potential energy associated with achieving a more favorable electron configuration.
Hence, B. is the correct option.

What is the frequency of a wave?
A the distance traveled by the wave during one full cycle
B. The distance from the beginning to the end of a cycle
C. The amount of cycles that occur in a given time
D. the amount of time that one full cycle takes
The frequency of a wave is the distance from the beginning to the end of a cycle. Therefore, option B is correct.
What do you mean by the term frequency ?Frequency is measured in hertz and is defined as the quantity of oscillations of a wave per unit of time (Hz).
The equation f = vλ , where is the wavelength in metres and v is the wave speed in m/s, may be used to determine the frequency of a wave if the wavelength and speed of the wave are known.
The quantity of waves that pass a set location in a predetermined period of time is known as frequency. Hence, if a wave passes through in half a second, the frequency is 2 per second. The frequency is 100 times per hour if it takes 1/100 of an hour.
Thus, option B is correct.

Which would not be associated with stable atmospheric conditions
afternoon thunder showers is the answer
The correct answer is - afternoon thunder showers.
When we say stable atmospheric conditions it means that the atmosphere should be relatively calm, without having any disturbances in it. A nice example for a stable atmospheric conditions is a clear sunny sky and a calm wind. On the other hand, we have the afternoon thunder showers. The afternoon thunder showers are the total opposite of stable atmospheric conditions. When they occur, there's lot of disturbances, air pressures are mixing, the winds are changing speeds, heavy rainfall occurs, the air pressure changes rapidly, there's electrical charges, all in all creating a real mess in the atmosphere.
Answer:
afternoon thunder showers.

Which 1.0 M acid solution has the largest concentration of hydronium [H3O+]?
HNO2
H2CO3
H2SO4
H3BO3
Answer:
H2SO4
Explanation:
OTHER ACIDS ARE WEAK ACIDS AND A VERY FEW AMOUNT OF H+ ARE RELEASED TO THE MEDIUM
The 1.0 M acid solution with the largest concentration of hydronium [H3O+] is H2SO4 (sulfuric acid). H2SO4 is a strong acid that completely ionizes in water, resulting in a high concentration of hydronium ions.
Explanation:The 1.0 M acid solution with the largest concentration of hydronium [H3O+] is H2SO4 (sulfuric acid).
When an acid dissolves in water, it donates hydrogen ions (H+) to form hydronium ions (H3O+). The concentration of hydronium ions is directly related to the strength of the acid. In this case, H2SO4 is a strong acid, meaning it completely ionizes in water, resulting in a high concentration of hydronium ions.
On the other hand, HNO2 (nitrous acid), H2CO3 (carbonic acid), and H3BO3 (boric acid) are all weak acids, meaning they only partially ionize in water and produce lower concentrations of hydronium ions.
What happens if someone let's go of the button on an electric door bell
Releasing the button on a doorbell opens the electrical circuit, stopping the flow of current and the bell's sound. This action is similar to how a circuit breaker works, by cutting off the electric current to prevent a continuous ring or possible overloading.
When someone releases the button on an electric doorbell, the electrical circuit that was completed when the button was pressed becomes open. This happens because doorbells are typically operated by a push button switch, which controls the flow of electricity. As long as the button is pressed, the circuit is closed, allowing electrical current to flow through and activate the bell or buzzer. Once the button is let go, the circuit opens, the current stops flowing, and the doorbell sound ceases.
Additionally, this action is akin to a circuit breaker in the way it interrupts the electrical flow. The breaker's electromagnet becomes less strong without the current, which in turn releases the moving contact, breaking the circuit. Though an electric shock from a doorbell is highly unlikely due to the low voltage involved, it's important to remember safety protocols when handling electrical circuits to prevent shock, reminiscent of the "can't let go" effect described with more dangerous voltages.

when 2.85 moles if chlorine reacts with excess tin hiw many moles of tin(IV)chloride are formed
When 2.85 moles of chlorine reacts with excess tin, 1.425 moles of tin(IV) chloride are formed.
Stoichiometry Calculation
To solve this problem, we need to use the balanced equation for the reaction between chlorine (Cl₂) and tin (Sn) to form tin(IV) chloride (SnCl₄):
Sn + 2Cl₂ → SnCl₄
This equation tells us that 1 mole of Sn reacts with 2 moles of Cl₂ to produce 1 mole of SnCl₄. In this case, chlorine gas is in excess, meaning tin is the limiting reactant.
Steps:
First, determine the number of moles of chlorine gas available: 2.85 moles of Cl₂.From the balanced equation, 2 moles of Cl₂ react to form 1 mole of SnCl₄.Therefore, the moles of SnCl₄ formed can be calculated by dividing the moles of Cl₂ by 2:Moles of SnCl₄ = 2.85 moles Cl₂ / 2 = 1.425 moles of SnCl₄
So, when 2.85 moles of chlorine reacts with excess tin, 1.425 moles of tin(IV) chloride are formed.

What started the Russo-Japanese War?
Answer:
Late in the night on February 8, 1904, Japan launched a surprise attack against the Russian-held Port Arthur, along the coast of Manchuria, beginning the Russo-Japanese War.
Explanation:
hope this helps
Final answer:
The Russo-Japanese War started due to territorial disputes in Manchuria and Korea, with Japan launching a surprise attack on Port Arthur in 1904. Japan's victory altered international relations and signaled the rise of Asian military prowess against European powers.
Explanation:
The Russo-Japanese War began primarily due to territorial rivalries in Manchuria and Korea. In the winter of 1904, Japan initiated the conflict with a surprise naval attack on the Russian fleet at Port Arthur because of Russia's military presence in Manchuria and its refusal to recognize Japan's interests in Korea. Industrialization in Japan played a crucial role, enabling its military to achieve rapid victories over Russia. This conflict ended with the signing of the Treaty of Portsmouth in 1905, with Japan gaining control over Korea and parts of Manchuria. The war not only demonstrated Japan's industrial military power but also influenced international dynamics by challenging European influence in Asia and stirring political unrest within Russia.
