Read the given passage where a few words are italicized and select the correct statement regarding them. The term cell was coined by Robert Hooke in 1665. Cells that lack a well-defined nucleus and membrane-bound organelles are called prokaryotic cells whereas cells that have a well-defined nucleus and membrane-bound organelles are called eukaryotic cells. Bacterial cells are prokaryotic cells whereas animal cells are eukaryotic cells.

Robert Hooke must be replaced with Robert Brown.

Prokaryotic cells should be interchanged with eukaryotic cells.

Animal cells must not be changed as it is correctly mentioned.

Bacterial cells must be replaced with plant cells.

Read the given passage where a few words are italicized and select the correct statement regarding them. The process of photosynthesis occurs in the chloroplasts of plant cells. During photosynthesis, carbon dioxide and water are converted into glucose and oxygen in the presence of sunlight. This process is crucial for the production of organic compounds that serve as food for the plant and, indirectly, for other organisms.

Photosynthesis must be replaced with respiration.

Chloroplasts should be interchanged with mitochondria.

Carbon dioxide must not be changed as it is correctly mentioned.

Read the given passage where a few words are italicized and select the correct statement regarding them. Newton's First Law of Motion states that an object will remain at rest or in uniform motion unless acted upon by an external force. This law is also known as the law of inertia. It explains why objects continue in their state of motion unless a force is applied to change that state.

Newton's First Law of Motion must be replaced with Einstein's Theory of Relativity.

Force should be interchanged with energy.

Law of inertia must not be changed as it is correctly mentioned.

Uniform motion must be replaced with accelerated motion.

Read the given passage where a few words are italicized and select the correct statement regarding them. The atomic number of an element is determined by the number of protons in its nucleus. Elements are arranged in the periodic table in order of increasing atomic number. The mass number is the total number of protons and neutrons in the nucleus of an atom, which determines its isotopic identity.

Atomic number must be replaced with atomic mass.

Protons should be interchanged with electrons.

Mass number must not be changed as it is correctly mentioned.

Neutrons must be replaced with protons.

Read the given passage where a few words are italicized and select the correct statement regarding them. The pH scale is a measure of the acidity or alkalinity of a solution. A pH value of 7 is considered neutral, values less than 7 are acidic, and values greater than 7 are alkaline. The pH scale ranges from 0 to 14 and is used in various chemical and biological processes to determine the nature of a solution.

pH scale must be replaced with temperature scale.

Acidity should be interchanged with alkalinity.

Neutral must not be changed as it is correctly mentioned.

Alkaline must be replaced with basic.

Read the given passage where a few words are italicized and select the correct statement regarding them. In a chemical reaction, the reactants are transformed into products. The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. This principle is fundamental to chemical equations, which must be balanced to reflect the conservation of mass.

Chemical reaction must be replaced with physical change.

Reactants should be interchanged with products.

Law of conservation of mass must not be changed as it is correctly mentioned.

Products must be replaced with reactants.

Read the given passage where a few words are italicized and select the correct statement regarding them. The nervous system consists of the brain, spinal cord, and nerves. It is responsible for receiving and sending signals throughout the body, enabling coordination and control of bodily functions.

Nervous system must be replaced with circulatory system.

Brain should be interchanged with heart.

Spinal cord must not be changed as it is correctly mentioned.

Signals must be replaced with hormones.

Read the given passage where a few words are italicized and select the correct statement regarding them. The water cycle involves the processes of evaporation, condensation, and precipitation. Water from oceans and lakes evaporates due to the heat from the sun, forms clouds through condensation, and returns to the surface as precipitation in the form of rain, snow, or hail.

Water cycle must be replaced with carbon cycle.

Evaporation should be interchanged with transpiration.

Condensation must not be changed as it is correctly mentioned.

Precipitation must be replaced with infiltration.

Read the given passage where a few words are italicized and select the correct statement regarding them. The heart pumps blood throughout the body through the circulatory system. The blood carries oxygen and nutrients to the cells and removes waste products like carbon dioxide.

Heart must be replaced with lungs.

Blood should be interchanged with plasma.

Oxygen must not be changed as it is correctly mentioned.

Waste products must be replaced with nutrients.

Read the given passage where a few words are italicized and select the correct statement regarding them. The solar system consists of the Sun and the celestial bodies that orbit it, including planets, moons, asteroids, and comets. The gravitational pull of the Sun keeps these bodies in orbit, ensuring the stability of the solar system.

Solar system must be replaced with galaxy.

Sun should be interchanged with Earth.

Planets must not be changed as it is correctly mentioned.

Gravitational pull must be replaced with electromagnetic force.
