- Scr0360: logical operators in
Summary
I provided an explanation of logical operators and truth tables. Then I
presented and explained a Scratch program that illustrates the use of thelogical
and ,
or , and
not operators when used in conjunction
with relational operators.
Finally, I provided the specifications for two student-programming projects
for you to demonstrate your understanding of what you learned from the firstprogram and from earlier modules. One of the student-programming projects is
relatively difficult requiring an understanding of DeMorgan's theorem
(see
Resources ) .
Copies of all three programs have been posted online for your review
(see
Resources for the URL) . If you
don't find the program using that URL, search the Scratch site for the usernamed dbal.
What's next?
Future modules using the Scratch programming language will continue to deal
with
selection and will also deal with
loops .

How bacteria create energy to survive?
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments

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
