Process by which the internal structure of a mineral is altered by the addition or removal of elements. Change in phase (mineral type) and composition are due to the action of chemical agents. Chemical weathering is dependent on available surface for reaction temperature and presence of chemically active fluids.
RR x rr
or if you're using the letter "t" to represent the alleles TT x tt
Homozygous means that a particular gene has identical alleles on both chromosomes. TT is for a dominant (stronger) trait and tt is for a recessive (weaker) trait.
Hope this helps! :)
KIA tubes and SIM tube in this exercise to determine whether or not your unknown produced H2S.
<h3>What gas is produced by Salmonella?</h3>
F0F1 ATP synthase activity is necessary for Salmonella typhimurium to produce hydrogen sulfide and fermentative gases.
<h3>H2S production by Salmonella enterica?</h3>
Infections with Salmonella enterica continue to have a serious impact on global public health. H2S-negative Salmonella have lately surfaced, despite the fact that the capacity of S. enterica to produce H2S is an essential phenotypic trait utilized to screen and identify Salmonella with selective media.
<h3>H2S is it produced by Shigella?</h3>
Shigella do not create H2S, hence colonies on Hektoen agar appear bluish-green rather than having the black center seen with Salmonella. Shigella are comparatively biochemically inactive and do not ferment lactose or xylose.

Answer:
B.) classification
Explanation:
In biology, classification is a way to organize living things. In science generally, this could expand to include any type of object.
I’m pretty sure it’s the second one
