Understanding anaerobic respiration Plants and microbes like animals sometimes need to respire anaerobically As in animals this process uses glucose to release energy But the products of anaerobic respiration in plants and microbes differ from the products in animals. Examining interacting muscles . There are commonly three things judges look for:. Symmetry . of the . muscles (how similar they are). Muscularity (how big they are). Level . of . conditioning (how toned they are. Understanding how seeds are dispersed by the wind . The largest seed in the world is 50 cm in . diameter.. It . comes from the palm tree called Coco de . Mer. , found only in the Seychelles islands in the Indian . Investigating chemosynthesis. Most living organisms depend on . sunlight. as their ultimate source of energy.. Green plants use sunlight to make food by . photosynthesis. .. In the darkness of the ocean depths there is no sunlight, but many organisms live there.. Calculating pressure. Calculating pressure is important to engineers.. For example, the foundations of a building have to carry the full downwards force of its weight.. There have been cases of buildings collapsing when the pressure on the foundations was too large.. Using Indicators . The traffic indicators on a car tell other vehicles when the car is going to . turn.. Indicators . in science can show us whether a substance is an acid or an . alkali.. Nature . is full of natural indicators and we can make use of these indicators in many ways.. Exploring Magnets. Magnets have many effects, sometimes surprisingly strong.. They have many uses including computer hard drives, loudspeakers, credit card strips, magnetic fasteners and compasses for navigation.. Exploring the importance of insects . Food security refers to the availability of food and the ability to obtain it. . What is the role of bees and insects in our food security?. How does agricultural practice impact on food security?. Analysing . adaptations . for respiration. They are both structures that transfer energy from type to another. .. Mitochondria provides energy for our . cells.. The power station provides energy for our homes. Changing . Physical state. When you make ice or melt the frost from a windscreen, you are making use of changes of . state.. What . is actually happening to the particles in these processes?. Introduction. Exploring the role of stomata. Plants are found in a huge range of habitats.. In order to . photosynthesise. , plants need a supply of carbon dioxide.. How do plants get carbon dioxide? Why does oxygen, a product of photosynthesis, not build up in the leaf?. The heart is odd one out. The heart is made from cardiac muscle. The bicep muscle (in the arm), the calf muscles ( in the legs) and the diaphragm (in the chest) are types of skeletal muscles.. Investigating muscle strength . Gemstones, such as amethyst, are crystal that formed deep in the Earth’s . crust.. Water . dissolved salts and as this solution cooled over thousands of years, the precious crystals formed.. Introduction. Symbols and simple diagrams can accurately represent an object, message or procedure, without requiring the skills of an artist.. Introduction. It is important to be able to represent how an . experiment. . Transmission Basics - Aseel AlHadlaq. Data vs Signal. Data – information formatted in human/machine readable form . examples: voice, music, image, file . Signal – electric or electromagnetic representation of data .
