Homeostasis:

It is a characteristic of a system that regulates its internal environment and tends to maintain a stable, relatively constant condition of properties.

In plant it is necessary to maintain homeostasis to function properly. Endocrine plays an important role in homeostasis as hormones regulate the activity of body cells and the release of hormones into the blood is controlled by a stimulus that either causes an increase or a decrease in the amount of hormone secreted.

Earth Scientist Earth science or geoscience is an all-encompassing term that refers to the fields of science dealing with planet Earth. It can be considered to be a branch of planetary science, but with a much older history. There are both reductionist and holistic approaches to Earth sciences.

Which solution has the greater concentration?

WITCHER [35]

The higher concentrated solution is 0.250 mole LiCl dissolved in 250 ml of solution

( B).0.250mole of LiCl diluted in 250ml solution

Explanation:

Procedure to find the intensity of the solution:

To find the intensity of the solution, we have to use the following formula

M1V1=M2V2

250mL of a 0.500 M aqueous solution of LiCl is diluted with water

$M1V1=(250) \times (0.500)=125M$

250 ml of a 0.250M aqueous solution of LiCl is diluted with water

$M2V2=(250) \times (0.250)=62.5M$

Thus the PH level of a solution increases from ascending order, Therefore the Solution with 62.5M is a higher concentration than that of the solution with 125M.

Una determinada cantidad de neón ocupa 0,5 litros (L) a 200ºC. Calcular el volumen que ocuparía a 0ºC si la presión se mantiene

Basile [38]

Answer:

$V_2=0.87L$

Explanation:

¡Hola!

En este caso, al considerar la información dada, inferimos que este problem se resuelve aplicando la ley de Charles, dado que tenemos una relación entre el volume y la temperatura:

$\frac{V_2}{T_2}=\frac{V_1}{T_1}$

Así, despejamos V2 (volumen final) y obtenemos:

$V_2=\frac{V_1T_2}{T_1}\\\\V_2=\frac{0.5L*473.15K}{273.15K}\\\\V_2=0.87L$

Saludos!

Which orbital would the electron of a ground state hydrogen atom occupy? 1s 1p 2p none of the above 0s?

noname [10]

From the periodic table, we can see that:
At ground state, the hydrogen atom has one electron
Based on the electronic configuration, at ground state this electron should be occupying the orbital (1s)

Since (1s) is not one of the choices, therefore, the answer is "none of the above"
