<h2>Active & Passive transport</h2>
Explanation:
- Active transport is where a chemical reaction using ATP moves things in/out of the cell through transport proteins within the cell wall. It uses a concentration gradient to trigger the reaction (it goes against the concentration gradient in active transport)
- Molecules move against a concentration gradient ( low concentration ―→ high concentration)
- Cellular energy (ATP) is required
- Passive transport also uses a concentration gradient by diffusion (hydrophobic or very small polar molecules) and facilitated diffusion via carrier proteins and channels
- Molecules move along the concentration gradient (high concentration ―→ low concentration)
- No cellular energy is required
Statements 1 and 4 are true, while 2 and 3 are false.
<h3>Decomposition reaction</h3>
In decomposition reactions, one or more reactants decompose to produce two or more products.
Decomposition reactions with single reactants are known as single decomposition reactions. Those with 2 reactants are known as double decomposition reactions.
Decomposition reactions do not always produce elements. It could be compounds in some cases.
Decomposition reactions always obey the law of conservation.

Halley — the traditional pronunciation of the name usually rhymes with valley — was born Nov. 8, 1656, in Haggerston, Shoreditch, London, England. His father was a prosperous soapmaker and property owner. Halley was tutored privately at home before entering St. Paul's School, where he excelled in mathematics and astronomy.
Halley entered Queen's College, Oxford, in 1673, when he was 17 years old. He brought with him a fine collection of astronomical instruments purchased by his father. While still an undergrad, he became a protégée of John Flamsteed, the Astronomer Royal. Halley made important observations at Oxford, including an occultation of Mars by the moon, and published papers on the solar system and on suns
