Explanation:
At the bottom of the energy pyramid, there would be the producers.
In here the producers are grass and wheat. (D)

Explanation:
Molar mass of NaCl = 58.44 g/mol
Mass of NaCl = 195 g
Volume of solution = 4.05 L
Molarity of solution is
![\dfrac{195}{4.05}\times \dfrac{1}{58.44}=0.824\ \text{M}](https://tex.z-dn.net/?f=%5Cdfrac%7B195%7D%7B4.05%7D%5Ctimes%20%5Cdfrac%7B1%7D%7B58.44%7D%3D0.824%5C%20%5Ctext%7BM%7D)
The molarity of the solution is ![0.824\ \text{M}](https://tex.z-dn.net/?f=0.824%5C%20%5Ctext%7BM%7D)
Moles of NaCl = 4.63 mol
Volume is given by
![\dfrac{4.63}{0.824}=5.62\ \text{L}](https://tex.z-dn.net/?f=%5Cdfrac%7B4.63%7D%7B0.824%7D%3D5.62%5C%20%5Ctext%7BL%7D)
The volume of the solution that contains the required amount NaCl is ![5.62\ \text{L}](https://tex.z-dn.net/?f=5.62%5C%20%5Ctext%7BL%7D)
Volume of solution = ![25.35\ \text{L}](https://tex.z-dn.net/?f=25.35%5C%20%5Ctext%7BL%7D)
Moles of solution is given by
![0.824\times 25.35=20.89\ \text{mol}](https://tex.z-dn.net/?f=0.824%5Ctimes%2025.35%3D20.89%5C%20%5Ctext%7Bmol%7D)
The number of moles of NaCl is
.
<span>The balance equation will be
234/91 Pa --> 234/92 U + </span>a beta particle
An example of it is potassium-40 nucleus. A beta particle has a high-energy and high-speed electron in the radioactive decay. These particles ranges <span> from 0 MeV to 4 MeV. It carry one charge only and it is positively charge, it is called positron.</span>
Answer:
For gene therapy, stem cells can be trained in a lab to become cells that can help fight disease. Liposomes. These fatty particles have the ability to carry the new, therapeutic genes to the target cells and pass the genes into your cells' DNA.
