Apathy is a lack of interest or emotion, often accompanied by a feeling of indifference.

Disparaging remarks are statements that criticize or belittle someone or something.

Mundane things refer to ordinary, everyday objects or activities that are not exciting or important.

Gargantuan refers to something extremely large or massive.

A figure of speech is a literary device that uses words or phrases in a non-literal way to create a special effect.

A metaphor is a figure of speech that compares two unlike things without using words like 'like' or 'as'.

Personification is a figure of speech that gives human qualities to inanimate objects or abstract ideas.

The eight rays of the sun on the Philippine flag represent the eight provinces that first revolted against Spanish rule in 1896. These provinces are: Manila, Cavite, Bulacan, Laguna, Batangas, Pampanga, Nueva Ecija, and Tarlac .

The 2025 General Appropriations Act, also known as the budget law, outlined the allocation of funds for different government agencies. In 2024, the act stated that there would be no allocated budget for a specific government agency.

Known for his bravery defending Tirad Pass during the Philippine-American War, this young Filipino hero sacrificed his life for his country.

Dr. Jose Rizal's final work, showcasing his love for Josephine Bracken, was unveiled by the National Museum of the Philippines on December 30, 2024. It offered a deeper glimpse into Rizal's personal life.

Marcela Agoncillo, a skilled seamstress, played a crucial role in crafting the first official flag of the Philippines. This symbol represented the unity and independence of the Filipino people.

The speaker implies that laughter in the face of death is perceived as madness. The knowledge of our inevitable demise makes any joy we experience seem pointless and, therefore, crazy.

Chromatid exchange: During meiosis, the two chromatids of a chromosome can break and then rejoin, exchanging genetic material. This point on the chromosome where they break and reattach is known as the chiasma.

Break and reattach: The chiasma is the point where two chromatids break and then rejoin, effectively trading genetic information.

The recoil velocity of the rifle can be calculated using the principle of conservation of momentum:

Momentum before = Momentum after

(Mass of rifle) * (Initial velocity of rifle) + (Mass of bullet) * (Initial velocity of bullet) = (Mass of rifle) * (Final velocity of rifle) + (Mass of bullet) * (Final velocity of bullet)

Since the rifle is initially at rest (initial velocity = 0), the equation simplifies to:

(Mass of bullet) * (Initial velocity of bullet) = (Mass of rifle) * (Final velocity of rifle) + (Mass of bullet) * (Final velocity of bullet)

The bullet's final velocity is 800 m/s as stated in the problem. We can plug in the values:

(9 kg) * (800 m/s) = (4.5 kg) * (Final velocity of rifle) + (9 kg) * (800 m/s)

Solving for the final velocity of the rifle, we get:

(Final velocity of rifle) = -800m/s

The negative sign indicates that the rifle's velocity is in the opposite direction of the bullet.

Compound A is an ionic compound because it melts at a high temperature, shatters easily when solid, and is a good conductor of electricity when dissolved in water. Ionic compounds have very strong electrostatic forces between the ions that need high temperatures to overcome. They also possess the property of being good conductors of electricity in solution or melted state because ions are present and can carry the charge.

A single orbital can hold a maximum of 2 electrons. The third sublevel has 3 orbitals (3s, 3p, and 3d). Therefore, the maximum number of electrons that a single orbital can hold in the third energy level is 2.

The Moon's orbit is tilted at an angle to the Earth's orbit around the Sun, preventing a lunar eclipse every month. The Earth, Moon, and Sun must align for a lunar eclipse.

In binomial nomenclature, every species is given a unique two-part name. The first part is the genus name, which is always capitalized.

Photosynthesis is the process by which plants convert light energy into chemical energy stored in the form of glucose. The light-dependent reaction is the first stage. This reaction is named so because light energy is required. It happens in the chloroplasts and produces ATP and NADPH. They serve as energy sources for the Calvin cycle.

Solids don't diffuse because their particles are packed tightly and can only vibrate in fixed positions. Their motion is restricted compared to liquids and gases.

Xylem is a vascular tissue that conducts water and minerals from roots to the rest of the plant; phloem is a vascular tissue that transports food made by photosynthesis from leaves to other parts of the plant. They are the primary transport systems in plants.

Global warming is the gradual increase in the Earth's average temperature due to the enhanced greenhouse effect. Greenhouse gases, such as carbon dioxide and methane, trap heat in the atmosphere and lead to an increase in global temperatures.

Volume expands proportionally with temperature. We can apply Charles's Law to calculate the final volume. Charles's Law states the volume of an ideal gas is proportional to the absolute temperature under constant pressure. It can be expressed like this: V1/T1 = V2/T2. Therefore, the final volume V2 = V1 x T2/ T1. Convert the temperatures to Kelvin. T1 = -10°C + 273.15 = 263.15K; T2 = 25°C + 273.15 = 298.15K. Plug in the values, V2 = 12L x 298.15K/263.15K = 13.65 L.

Heat is a form of energy resulting from the motion of molecules. It is measured in calories (cal) or joules (J).

Elements and compounds are the two main categories of pure substances.

The tropics are located between 30 degrees North and South of the equator and receive large amounts of energy from the Sun due to the direct angle of the sun's rays. This results in consistently warm temperatures and a tropical climate.
