Every cell of the organism has the same DNA sequence and same genes. However, not all genes are expressed in every single cell at the same time. Only those genes necessary for a specialised function of a specialised cell are expressed in the specialised cell. For example, skin cells have some different proteins than nerve cells. Genes responsible for those "skin proteins" are activated in skin cells and are turned off in nerve cells.
Two primary techniques to identify use cases are USER GOAL TECHNIQUE AND EVENT DECOMPOSITION.
Use case refers to an activity which a system perform as a result of the request input by a user.
User goal technique is used to determine the specific goal that must be perform by the system for the user; user goal technique identify all the users of the system and their goals for using the system.
The event decomposition is used to determine the event to which the system must respond.<span />

Explanation:
<span>Penicillium does not seem to have sexual phase</span>
I believe the correct answer is true. Veins are often formed from hot water solutions. Hydrothermal deposits are a very common method of filling already existing fractures and occurs at varying depths. T<span>here are lots of veins formed by hot water that cause fractures or work their way up into non fractured rock. </span>
