1. Which aspects of soil do you think are easiest to change? Which are more difficult

1 answer:

7 0

Difficult to change - nutrients! crops won’t grow on soil that has had all of the nutrients used up. example: after growing corn in the same place for 50 years, corn will not grow anymore because all of the nutrients it needs to grow will no longer be in the soil

Which flowchart correctly shows how genes are inherited?. . A. DNA→ RNA→ protein→ trait. . B. trait→DNA→ protein→ RNA. . C. RNA→

WINSTONCH [101]

I believe the correct answer among the choices presented above is option A. The flow that correctly shows how genes are inherited is DNA→ RNA→ protein→ trait. The DNA gets transcripted into RNA which is translated to the proteins which turns into traits.

What do the numbers 3 and 4 refer to in 3NH4

xz_007 [3.2K]

The numbers 3 and 4 means that there are 3 Nitrogen atoms, and 12 Hydrogen atoms in the chemical formular (3NH4). The 3 coefficient in front of the compound applies to all of the elements while the 4 applies to only hydrogen (H). This means that the compound contains 3 Nitrogen atoms and 12 (4 multiplied by 3) Hydrogen atoms.

Electrons in the outermost energy level are usually involved in chemical reactions which are called ___________________ .

Elena-2011 [213]

Answer:

Chemical bonding

Explanation:

Outer most shell's electrons are called valence electrons and they are responsible for the formation of chemical bonds either ionic or covalent when atoms react with each other.

Outer most electrons hold immense importance in the type of chemical bonding an atom will go through in the formation of a molecule.

For example, sodium has only one electron in outermost shell so it is very hard for sodium to share electrons and become stable. Therefore, it never goes for covalent bonding but only goes for ionic bonding where it gives off one electron to another atom (say chlorine who has 7 electrons in outermost shell) and in this process sodium chloride is formed and both sodium and chlorine get stable electronic configuration.

Please see picture for better understanding. Therefore, we can say that Electrons in the outermost energy level are usually involved in chemical reactions which are called chemical bonding or formation of chemical bonds.

Hope it help!
