In the south, an older mountain range was formed 300 million years ago, then eroded away. The rocks of that older range were reformed into the Rocky Mountains. The Rocky Mountains took shape during an intense period of plate tectonic activity that resulted in much of the rugged landscape of the western North America.
Dolphins eat the equivalent of 4-5% of their body mass each day. The sonar frequency most often used by thedolphins is around 100kHz. Notice thequalitative data are descriptions. Thequantitative data are objective, numerical measurements.
The correct answers are: The lipid bilayer and proteins exist side by side without covalent bonds between them and Some proteins and lipids undergo lateral diffusion along the inner or outer surface of the membrane
According to fluid mosaic model, there is a lipid bilayer that gives fluidity and in which the protein molecules are embedded.
The membrane is mosaic because there is a pattern of different types of molecules that are put together. Molecules are constantly moving in two dimensions.
Components of the cell membrane include:
• Phospholipids – Form a bilayer
• Cholesterol –improves stability and reduce fluidity
• Proteins –integral (transmembrane) or peripheral
• Sugars-usually attached to proteins.
I don't know your chart, but I can provide some data:
Niger's migration rate is -0.5/1000 people: this migration rate is negative, which means that more people leave Niger than enter it.
Italy's migration rate is 4.2/1000 people: this means that more people enter Italy and settle there than leave it.
