Answer:
Polar
Explanation:
Polar is a concept which explains the formation of a particular molecule as a result of a separation of electric charges. In such molecule formed, there is a negatively charged end and a positively charged end. The difference in their electronegativity is what determines the strength of the bind formed in the molecule.
Electrically charges object can be used to attract molecules that are polar. This is because, when polar molecules are placed in an electric field, the positive charged end tends to align with the negative plate while the negatively charged end tends to align with the positive end.
Examples of polar molecules are water, hydrogen sulphide, ethanol, and some others.
Answer:
Agua
Explanation:
El agua costituye aproximadamente 3/4 partes de la tierra, 70% del cuerpo humano esta constituido por agua, y aproximadamente el 90% de las células contiene agua. Esta sustancia es la mas importante para el funcionamiento de nuestro organismo y para alcanzar un equilibrio. Todos los seres vivos dependen del agua para sobrevivir, desempeñando un rol único y central en el funcionamiento de los sistemas vivos.
El agua cumple diversas funciones en el organismo, entre ellas, como las mencionadas en el problema, se encuentra:
- Regula la temperatura del cuerpo. Dependiendo de la temperatura ambiental, las moleculas de agua permiten que el cuerpo mantenga la temperatura si el ambiente esta frio, y emane calor si la tempeartura ambiental es elevada.
- Convierte los alimentos en energía. Cumple un rol principal en la descomposición bioquímica de alimentos.
- Ayuda a llevar nutrientes y oxígeno a las células. Una vez extraidos los nutrientes, se convierte en el medio por el cuál estos últimos pueden transportarse hasta alcanzar las celulas de destino final.
- Conforma el 83% de la sangre. Como se mencionó previamente consituye la mayor parte de la sangre. Solo el plasma sanguineo esta constituido por el 90% de agua.
Answer:
1 x 10^13 stadiums will be needed in this scenario
Explanation:
We are told that
1 stadium holds = 1 × 10^5 people and
Number of iron atoms = 1 × 10^18 atoms
If the stadium carries an equivalent number of atoms as that of people.
We can infer that 1 stadium will carry 1 × 10^5 atoms.
The calculation to determine the number of stadiums would then be 1 × 10^18 divided by 10^5 atoms/stadium which was gotten by dividing the total number of atoms by the number of atoms per stadium.
Number of stadiums = Total number of atoms ÷ Number of atoms per stadium
= 1 × 10^18 atoms ÷ 1 × 10^5 atoms/stadium
= 1 × 10^13 Stadiums
This means that 1 × 10^18 atoms would occupy 1 × 10^13 stadiums
Answer:
Salivary glands make saliva, which aids in digestion, keeps your mouth moist and supports healthy teeth. You have three pairs of major salivary glands under and behind your jaw — parotid, sublingual and submandibular. Many other tiny salivary glands are in your lips, inside your cheeks, and throughout your mouth and throat.
