Multicellular organisms need organ systems so that different functions may take place. For example, our bodies are divided into numerous important systems that we depend on to live. Our respiratory system to breathe, which is where our lungs are, our digestive system to supply our cells with nutrients in order to function which is why we need sustenance.

Complex organisms need cells that can perform many different functions. they need to be supported on a cellular level. Without specialized cells you they won't be able to perform different functions.

Do you think it is possible for scientists to incorporate chloroplasts into the skin cells of humans? What would this mean for h
Alisiya [41]

Similarly to mitochondria on which the animals and fungi rely upon, the chloroplasts are the solar-power plants of the plant cell. With the advancement in the field of genetics and biotechnology, it may be feasible for scientists to incorporate chloroplasts into human skin cells. However, there may be few issues, which the human beings would have to encounter with, these are as follows:  

1. The immune system of the humans may attack the chloroplasts, but maybe they would be safe if they are present within the cell.  

2. As the skin of the humans would be undergoing the process of photosynthesis, then they would have to be in green color, thus, the melanocytes of the skin would have to be engineered in order to generate another pigment.  

3. The humans may get skin cancer and sunburns when they would be out feeding on sunlight, that is, the ultraviolet part of the sunlight would cause the destruction of the living cells.  

4. In order to undergo the reaction of photosynthesis, the humans would require more water than usually required by a normal human being, and this could be a disadvantage in a desert surrounding.  

5. The process would not help to generate much energy for an active species like humans, as the daily energy requirements for a human being would be attained by absorbing around 10000 kJ of energy, that is, around 150 hours in a day of sitting in the Sun, which is impossible.

How many grams of urea (non volatile, non electrolyte) must be added to 1250. g water to give a solution with a vapor pressure l
Lady bird [3.3K]

Answer:

\large\boxed{\large\boxed{107g}}

Explanation:

The <em>vapor pressure lowering</em> is a colligative property and it follows  Raoult's law.

The <em>vapor pressure lowering</em> of a solvent in a solution, ΔP, is equal to the mole fraction of the solute, Xsolute, multiplied by the vapor pressure of the pure solvent, P°.

               \Delta P=X_{solute}\times P^0

ΔP and P⁰ are given:

  • ΔP = 1.39mmHg
  • P⁰ = 55.32mmHg

<u>1. Mole fraction of solute</u>

Thus, you can calculate Xsolute:

           1.39mmHg=X_{solute}\times 55.32mmHg\\\\X_{solute}=0.02513

<u>2. Moles of solute</u>

Now you can calculate the number of moles of water and the number of moles of solute.

  • Number of moles of water = mass in grams / molar mass

  • Number of moles of water = 1,250g/18.015 (g/mol) = 69.3866mol

  • Xsolvent = 1 - Xsolute = 1 - 0.02513 = 0.97487

  • Xsolvent = moles of solvent / moles of solution

  • 0.97487 = 69.3866mol / moles of solution

  • moles of solution = 71.1752mol

  • moles of solute = moles of solution - moles of solvent = 71.1752mol - 69.3866mol = 1.7886mol

<u>3. Mass of urea</u>

Formula:

  • Mass = number of moles × molar mass
  • Mass = 1.7886 mol × 60.06 g/mol = 107.42 g

You must round to 3 significant figures: 107 g
