Answer:
A)They can be cheaper.
Explanation:
Non-renewable energy is the type that comes from sources which aren’t renewable.They usually run out and can’t be replenished in many lifetimes to come.
Example of non-renewable energy sources include fossil fuels: coal, petroleum, and natural gas.
Non-renewable energy is what is used in today’s word to power our generator, cars and to generate electricity despite being non-renewable.
This is mainly due to the fact that it’s mostly cheaper than other sources of energy.
Answer:
A
Explanation:
They increase the size of the study so that the risk estimates are significant
All of the cells within a complex multi-cellular organism such as a human being contain the same DNA; however, the body of such an organism is clearly composed of many different types of cells.
<u>What, then, makes a liver cell different from a skin or muscle cell</u> is <em>the way each cell deploy (utilizes) its genome</em>. In other words, the particular combination of genes that are turned on (expressed) or turned off (repressed) dictates cellular morphology (shape) and function. This process of gene expression is <em>regulated by cues</em> from both within and outside cells, and the<em> interplay </em>between these cues and the genome <u>affects essentially all processes</u> that occur during embryonic development and adult life.
Outside/Environmental cues include small molecules, secreted proteins (growth factors or signaling molecules), temperature, and oxygen.
The signaling molecules trigger intercellular signaling cascades (series of chemical reactions) that ultimately cause semipermanent changes in expression of genes. Such changes in gene expression can include turning genes completely on or off.
This process is thought to regulate a vast number of cell behaviors, including cell fate decisions during embryogenesis, cell function, and chemotaxis (i.e. cell movement in response to concentration gradient of a particular substance.)
Answer:
phobia
Explanation:
Phobia defined as irrational fear against something. The fear will cause anxiety feeling that make the threat feels much bigger than it should be. (For example, some people have a phobia of insects, and will scream uncontrollable and sobbing every time they see one of them)
A person will determine a situation as dangerous or threatening based on their past experience. This will vary greatly, which make phobia can come from any condition. Many phobias not comes from a dangerous or life-threatening condition but acquired from a really unpleasant memory.
