Differences and similarities between igneous , metamorphic , and sedimentary rocks . sedimentary rocks are formed by weathered sediment using cementation or precipitation on Earth's surface . Metamorphic rocks are formed by changes of pressure and temperature within Earth's surface .
The skin is an example of a non-specific defense.
For example, bacteria or diseases have trouble entering a healthy person's skin because it is formed by closely packed cells with multiple layers and a substance called keratin that protects is.
On the other hand, the immune system is a specific defense mechanism.
When bacteria is able to enter the body in cases of fever for example, the immune system is activate and sends out protector cells such as the white blood cells to combat infection.
The hypothesis devised in this study by the researcher is –
" White fly nymphs escape predation because of their translucent bodies."
In order to test this hypothesis, the researcher is required to conduct an experiment where two sets of white fly nymphs are formed and fed to their predators. The two set of subjects would be -
Set I – White fly nymphs with translucent bodies
Set II- White fly nymphs with translucent bodies coated with harmless dyes.
The number of predated flies in each set can be compared to deduce justification for assumed hypothesis.
Hence, option B is correct
The cellular activity that does not requires the use of energy in the cell is facilitated transport.
<h3>What is facilitated transport?</h3>
We know that passive transport is a type of transport that does not require energy. Facilitated transport is a type of passive transport. This is because, it does not involve a movement against the concentration gradient. On the other hand, active transport is a movement against concentration gradient.
Hence, the cellular activity that does not requires the use of energy in the cell is facilitated transport.
