The angle formed between the line of pull of a muscle and the longitudinal axis of the bone in which the muscle is acting. The line of pull is usually indicated by the joint angle. It affects the strength of muscle action; at only certain angles of pull can a muscle exert maximal tension.
The amount of money paid into a company by its owners is referred to as the invested capital.
<h3>What is the invested capital?</h3>
The expression 'invested capital' makes reference to the physical resources (generally cash) that is provided to a company for its development/growth.
The invested capital is a fundamental issue for the success of a company or organization, especially in the early stages of development.
The invested capital of a given company can be mathematically estimated by adding assets and subtracting liabilities, which in the economy field is known as a balance sheet.
In conclusion, the amount of money paid into a company by its owners is referred to as the invested capital.

The only reaction that will most likely take place based on the activity series is; C: Ba + Na₂CO₃
<h3>Activity Series</h3>
From the activity series given, we can say that during a displacement reaction, the more reactive metal will always displace the lesser reactive metal from a compound.
Let us look at each of the given options;
A) Ag + FeCl₃
From the activity series, Silver(Ag) is less reactive than Iron(Fe) and as such Silver cannot displace iron from its' compound.
B) Zn + CaO
Zinc (Zn) is a less reactive metal than Calcium (Ca), so it cannot cannot displace Calcium from its' compound.
C) Ba + Na₂CO₃
Barium (Ba) is a more reactive metal than Sodium (Na), and therefore Barium will displace sodium from its compound in a displacement reaction.
D) Cr + KNO₃
Chromium (Cr) is a lesser reactive metal than Potassium (K), and it therefore cannot displace Potassium from its compound.
Complete question is;
Which reaction will most likely take place based on the activity series? Li > K Ba > CaNa > Mn > Zn > Cr> Fe> Cd Ni > H > Sb > Cu > Ag > Pd > Hg > Pt
A. Ag + FeCl₃
B. Zn + CaO
C. Ba + Na₂CO₃
D. Cr + KNO₃

Collagen is referred as the feature which is associated with the maturation phase of normal wound healing through its deposition on the wounded or injured area.
<h3>What is Collagen?</h3>
This is referred as a type of protein which is found in connective tissues and its role is to provide structural support to the different tissues which are found in the body system.
Collagen stimulates new tissue growth by attracting fibroblasts and encouraging deposition of more of it to the affected area. This helps the cells to be formed from pre-exising ones.
This is therefore the reason why collagen was chosen as the most appropriate choice in this type of scenario.
