Answer:
526.12 μm³
Explanation:
Given that;
A typical human cell is approximately 10.00 μm in diameter &
enclosed by a membrane that is 8.000 nm thick.
What is the volume of the cell including the membrane?
First, let's determine the radius of the human cell=
= 
= 
= 5 μm
Now, the radius of the cell including the membrane
= 5 μm + 8.000 nm
= 5 μm + 0.008 μm
= 5.008 μm
The volume of the cell including the membrane is given by the formula:
![V_{cell]= \frac{4}{3} *\pi *(r_{cell})^3 um^3](https://tex.z-dn.net/?f=V_%7Bcell%5D%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%5Cpi%20%2A%28r_%7Bcell%7D%29%5E3%20um%5E3)
526.1160731 μm³
526.12 μm³
Answer:
The correct option is;
Water absorbing energy in large amounts to increase energy by a degree of temperature
Explanation:
The growth of trees to towering heights has to do with the formation of plant cell walls which are built by the aggregation Glucose molecules to form Cellulose molecules. The cellulose molecules further combines to form microfibrils by forming hydrogen bonding. The microfibrils that combine to make cell walls
Therefore, the growth of a tree is dependent on the formation of hydrogen bonds between water molecules to enable uptake of water into the plants which enable photosynthetic reaction that result in the formation of glucose
The transpiration, which is the conversion of water into vapor or gas at the leaves facilitates the uptake of more water for the formation of more glucose molecules and creation of hydrogen bonds
The hydrogen bonds between chlorophyll molecules is facilitated by forming hydrogen bond with water molecules.
The correct answer is: D) excited
A molecule is in an excited state when its energy level is higher than the ground state. That molecule stays in excited state for short time and then returns to a state with lower energy. This return to a lower energy level is described as decay and is the inverse process of excitation.
The transition from ground to excited state of an atom is possible if electrons gain energy that is higher than the difference in energies between the two energy orbits.
