3 different characteristics
Arctic temperatures are increasing; the Red Fox is expanding its habitat to compete with arctic fox. Arctic temperature is a climate characterized by being long, cold and short winters and a cool summer. The Arctic is largely surrounded by land it consists of an ocean.
Renewable resources are easily obtained and can be created quickly. Things like fossil fuels take millions of years to create. C is the answer because as k stated fossil fuels are nonrenewable and take millions of years to create, Soybeans are easily made so it's renewable.
Hope I helped. :)
Answer:
Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions.
Explanation:
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.)
