Answer
I added 4 and 5 as an attachment due to time constraint.
Explanation:
1. at a steady state ca2+ taken by vesicle = 40n/mol
enclosed volume of CSR = 5μ/mg
concentration of ca2+ in vesicle =
40*10⁻⁶/5x10⁻⁶
= 0.008
= 8x10⁻⁹mol/L
2. radius of circle =75nM
volume = 150nm
volume of vesicle = 4/3 x pi x r³
= 1.33 x 3.14 x (75x10⁻⁹)³
= 1.77 x 10⁻²¹
when we convert this we get
1.77x10⁻¹⁸L since 1m³ is equal to 100oL
surface area =4x3.14x(75x10⁻⁹)²
= 12.56x5.625⁻¹⁵
= 7.065x10⁻¹⁴m²
this is 7.065x10⁻¹⁰cm²
3. number of vesicle/CSR
= 5x10⁻⁶/1.77x10⁻¹⁸
= 2.824x10¹²
surface are = 2.824x10¹² x7.06x10⁻¹⁰
= 19.95x10²
The answer is halite i hope this helps
Answer:
Here are the options to complete the question
A. plants
B. animals
C. inorganic compounds
D. genetic engineering
The CORRECT ANSWER IS D.
D. genetic engineering
Explanation:
Drugs can be produced or obtained by extracting the essential component needed from a plant source, animal source and inorganic compounds.
Genetic engineering is a synthetic source of drug production, needed to solve or make ready drugs with the aid of advanced technology/process.
Capillary action<span> (sometimes </span>capillarity<span>, </span>capillary motion<span>, or </span>wicking<span>) is the ability of a </span>liquid<span> to flow in narrow spaces without the assistance of, or even in opposition to, external forces like </span>gravity<span>. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper and plaster, in some non-porous materials such as sand and liquefied </span>carbon fiber<span>, or in a cell. It occurs because of </span>intermolecular forces<span> between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of </span>surface tension<span> (which is caused by </span>cohesion<span> within the liquid) and </span>adhesive forces<span> between the liquid and container wall act to propel the liquid.</span><span>[1]</span>
