<span>Since the early 1990s, geneticists have produced "genetically modified" crops that yield fruits and vegetables commonly found in U.S. supermarkets. Genetically modified plants (and also applicable to animals) in agriculture are those plants whose DNA are being modified using genetic engineering techniques.</span>

1 Electronegativity is the ability of an atom to attract electrons.
Explanation:
Answer: x=41
Sin, cos and tan are part of the trigonometric function. Sin is calculated from opposite/hypotenuse, while cos is calculated from adjacent/hypotenuse.
There is some formula that can be derived from the equation. One of them is sin (90-x)= cos x
If you use it, the calculation would be:
<span>sin 49° = cos x
</span><span>sin 49= sin (90-x)
49= 90-x
x= 90-49= 41</span>
Answer:
3
Explanation:
At pH 3, the pentapeptide Ala-Glu-His-Val-Cys would contain two positively charged groups and one negatively charged group.
This is evident in that peptides have both carboxylic and amino groups.
Given that peptides have a certain amount of H⁺ and OH⁻ ions, it converts to zwitterions.
This conversion process is based on pKₐ and pKb of the acid and the base accordingly.
Therefore, they have two positively charged groups and one negatively charged grou
Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. ... Solids, liquids and gases all expand when heat is added.
