Answer:
cientists would use a control sample that has no DNA from bighead carp in Edna surveillance in order to verify that no DNA has contaminated the gel. It would eliminate certain errors in the experiment. What are some of the things that your DNA can be contaminated with?
Explanation:
Answer:
There is currently no consensus regarding the definition of life. One popular definition is that organisms are open systems that maintain homeostasis, are composed of cells, have a life cycle, undergo metabolism, can grow, adapt to their environment, respond to stimuli, reproduce and evolve.
Explanation:
Chemical work, mechanical work, and transport work.
Chemical: An example would be the ATP building large molecules such as proteins for the cell (s)
Mechanical: An example of this would be the contraction of your muscle (s). The reason for this is because In your muscle cells, ATP transfers phosphate groups to certain proteins which allows them to then change shape starting a chain of events leading to your muscles contracting
Transport: An example would be transport work pumping solutes into a cell membrane.
Hope this helps! :)
Answer:
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lack soil.
Secondary succession is one of the two types of ecological succession of a plant's life. It is the process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil.
Explanation:
Primary succession takes time for completion around 1000 years, whereas secondary succession area takes 200 years for completion. In primary succession, there is a lack of soil and humus for the sustaining of life whereas, in secondary succession, soil and humus are present with some organisms.
A Secondary succession can take a few hundred years.
Heterotrophs, or consumers, are organisms that must obtain energy by consuming other organisms (autotrophs or other heterotrophs) as food.
