Because, if you want to design something, you NEED to know the history or backstory to the product. If some technology is similar to what you are creating, then you can use a similar technique or process. Also so you can design the product to the targeted audience. EX: Young children, teens, older adults.
Since they have no predators the zebra mussel population will grow rapidly. Whatever the zebra mussels consume will have a major decrease in population since there are so many zebra mussels.
Answer:
<u>Provide support and energy</u>
Explanation:
Polysaccharides are made up of many monosaccharides the common types include starch, cellulose, glycogen, chitin and lignin. Starch is present as stored food in plant tissues and can be hydrolysed into monosaccharides to provide energy.
Cellulose and chitin are structural components. They give the plan cells their definite shape and the exoskeleton in arthropods respectively.
Answer:
The statement "oceanic conditions determine human activities" may be interpreted in many ways.
1. Oceanic conditions determine human activities in that the moon cycle influences the tide. As the moon cycle is said to greatly influence human activity, and the tide changes as the moon does, it may also be concluded that the tides have a similar influence on human activity.
2. Weather conditions may also influence oceanic conditions.
a) Hurricanes and typhoons occur in the ocean and if they make landfall, humans are sometimes required to evacuate the location they will affect. The process of evacuation, and the reparations necessary to human civilization afterward, are both examples of oceanic conditions being influential to human activity.
b) Flooding and tsunamis may also result in evacuation, and damage to human civilization.
c) Global warming, which is resulting in the melting of the polar ice caps, contributes to rising sea levels. Rising sea levels are also oceanic conditions that may affect human civilization in the forms of flooding, erosion, and the ocean expanding, and also determine human activities.
1 c is the answer. <span>Energy is not created or destroyed; it can change form or can be transferred.
2d work is calculated as newton x </span>displacement so 60 x 4= 240 joules
