Answer: <u><em>D. An observation that has a number associated with it</em></u>
Explanation: The answer is D. An observation that has a number associated with it. I would explain further, but it is pretty self explanatory.
<em>Good luck!</em>
You may have feelings of inadequacy when you can't have—or give your children—the kind of life that others seem to have. All of these situations and challenges can lead to stress, which in turn lead to the development of Self Defeating Behaviors (SBD).
<h3>What is beneficial traits?</h3>
- Beneficial traits are extremely varied and may contain anything from protective coloration to the ability to operate a new food source, to a change in size or constitution that might be useful in a certain environment.
- Over time, these favorable traits become more common in the residents. Through this process of natural preference, favorable characteristics are transmitted through generations. Natural preference can lead to speciation, where one species gives rise to a new and distinctly different species.
- The artificial section is the identification by humans of seductive traits in factories and animals, and the steps taken to enhance and memorialize those traits in future years.

The right answer is C
This process is called anaerobic respiration. It doesn't need dioxygen to occur (it can happen with or without O2).
Anaerobic respiration is a mechanism in which electrons pass through a chain of transporters whose final acceptor is a mineral substance other than oxygen, unlike aerobic respiration where the final acceptor is dioxygen. The final acceptor may be the nitrate ion (as in the case of Pseudomonas), carbon dioxyde or the sulfate ion.
Some bacteria (Pseudomonas) are able, anaerobically, to reduce nitrates to nitrites and then, depending on the case, to dinitrogen (with the enzyme Nitrate reductase A).
NO3- ==> NO2- ==> N2.
Why is the active site specific for only one type of substrate? Enzymes have a lock and key type fit so only a specific substrate fits in the activation site.
Answer: The cells have differentiated.
Explanation:
The process by which a cell changes from one type to another is called cellular differentiation. When this happens, the cell changes to a more specialized type. So this creates differentiated daughter cells which are important in a multicellular organism because <u>they are able to perform different and specialised functions</u> in an organism.
