- Scr0380: the forever and repeat
The second program uses a
forever block in conjunction with an
embedded
if block and a counter variable to create a counter loop.
That program was used as the jumping-off point for a discussion of thesimilarities and differences between a
forever/if block combination and a
repeat block.
The third program uses a
repeat until block to cause a sprite to run
in a small circle until the user pressesthe space bar. I pointed out that
unlike the
forever block, it is possible to connect another block to
the bottom of a
repeat until block. Therefore, it is not necessary for a
repeat until block to be the last block in a script.
Finally, I provided the specifications for a student-programming project for
you to demonstrate your understanding of what you learned from the threeprograms listed above and from earlier modules.
What's next?
One of the new features of Scratch v2.0 is the ability for you to create your
own blocks. The next module will discuss that feature.

explain assimilatory nitrate reduction
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
