Answer:
The overall three-dimensional structure of a polypeptide is called its tertiary structure. The tertiary structure is primarily due to interactions between the R groups of the amino acids that make up the protein. ... These include hydrophobic interactions, ionic bonds, hydrogen bonds, and disulfide bridge formation.
Nails are made of iron because, iron is strong and sturdy; although nail rust when it undergoes oxidation when expose to water but it is not explosive.
Barium and phosphorus are not suitable for nail making because of their properties.
Barium is an element which reacts with virtually all non metals, forming poisonous products which are dangerous to health and to the environment. It also reacts explosively with water.
Phosphorus is not found in its pure form in nature, it conducts electricity and it is combustible in nature.<span />
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
To compensate for this dragging, the patient will bend the knee to lift the foot higher than in a normal stride (high steppage). Foot drop typically affects the muscles responsible for moving the ankle and foot upward, specifically the anterior tibialis, extensor halluces longus, and extensor digitorum longus.
Answer:
1-a voice of one calling in the desert, `Prepare the way for the Lord, make straight paths for him. '" And so John came, baptizing in the desert region and preaching a baptism of repentance for the forgiveness of sins.
2-God
John 1:1 is the first verse in the opening chapter of the Gospel of John in the New Testament of the Christian Bible.

3-Matthew 5 is sometimes referred to as the “Sermon on the Mount.” The main focus is on Jesus educating his disciples. He begins preaching to the masses on a mountaintop. The beginning of his message outlines who is blessed and why they receive these blessings.
