Explanation:
Genetic alterations made to an organisms DNA would cause the synthesis of certain proteins that would lead to improvement in that organism’s ability to survive in and through specific components of its environment.
In the context of agriculture, potential benefits of genetic engineering include allowing agricultural organisms to thrive in any environment they were to be grown in, and to fight and persist against biological threats, such as a harmful bacteria.
Overall, potential benefits of genetic engineering in agriculture can be summarized improving the agricultural industry: higher productivity, quality, and efficiency of the crops.
To balance chemical equations, what must be done is the same number of each element in the input must be present in the output. For example, photosynthesis.
H2O + CO2 —> C6H12O6 + O2
As can be deduced, the input only has 2 H, 1 C, and 3 O. Whereas, the output has 6 C, 12H, and 6 O. When balancing I recommend to balance the unique elements if possible (for example, H is only in one molecule on each side)
So you get 6(H2O) + 6(CO2) —> C6H12O6 + 6(O2)
Hope this helped!
Answer is: <span>Mutations sometimes improve the chances of survival for a plant.
</span>Mutations are very important because they change <span>variability in populations and in that way enable evolutionary change.
</span>There are three types of mutations:
1) good or advantageous mutations - <span> improve the chances of survival for a plant.
2) </span>bad or deleterious - decrease the chances of survival for a plant.
3) neutral - not affect he chances of survival for a plant.
MZn: 65 g/mol
mZnCl₂: 65g+35,5g×2 = 136 g/mol
.....................
Zn + 2HCl -----> ZnCl₂ + H₂
65g.......................136g............
65g Zn ---- 136g ZnCl₂
3,57g Zn ---- X
X = (3,57×136)/65
X = 7,47g ZnCl₂
