Here are the answers to the questions: Section B Question 1: Energy and Germination i)* Energy is the capacity to do work or produce heat. ii)* Four forms of energy are: 1.* Chemical energy 2.* Electrical energy 3.* Mechanical energy 4.* Thermal energy iii)* Germination is the process by which an organism grows from a seed or spore. It typically involves the sprouting of a seedling from a seed of a flowering plant or conifer. iv)* Two types of germination are: 1.* Epigeal germination (cotyledons emerge above ground) 2.* Hypogeal germination (cotyledons remain below ground) Question 2: Soil and Erosion i)* Soil is the loose surface material of the Earth, composed of organic matter, minerals, gases, liquids, and organisms, that supports plant life. ii)* Four types of soil are: 1.* Sandy soil 2.* Clay soil 3.* Loamy soil 4.* Silty soil iii)* Erosion is the process by which natural forces like water, wind, ice, or gravity wear away and transport soil and rock from one location to another. iv)* Four causes of erosion are: 1.* Wind 2.* Water (rain, rivers, waves) 3.* Ice (glaciers) 4.* Gravity (landslides, mass wasting) Question 3: Define the following terms i)* Electricity is a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current. ii)* An atom is the smallest unit of ordinary matter that forms a chemical element, consisting of a nucleus (containing protons and neutrons) surrounded by electrons. iii)* Technology is the application of scientific knowledge for practical purposes, especially in industry, or the machinery and equipment developed from such scientific knowledge. iv)* Food is any nutritious substance that people or animals eat or drink, or that plants absorb, in order to maintain life and growth. v)* Friction is the force that opposes motion between two surfaces in contact.
