Answer:
12
Explanation:
Suppose the four different strains are P, Q, R, S. Thus, the first infection can be from any of the four strains and it occurs in 4 ways.
Since an individual cannot be infected again with the strain from which he/she is been previously infected;
Then, at the second time;
The possible number of strain to be infected with = 4-1 = 3 ways
Thus; the number of possible different levels of severity can be viewed by forming two lettered word P, Q, R, and S without repetition which is:
= 4 × 3
= 12
The tissue that predominantly contains fibers that form a netlike support structure is the connective tissue.
<h3>What is the connective tissue?</h3>
Connective tissue is one of the types of primary tissues which has the function of supporting and integrating the rest of the cells since it is the tissue that gives a union of different tissue elements that make up the organs.
This tissue helps move nutrients to the cells they contain in order to give them nutrition, they can also transport other types of substances. Within the types of connective tissue are cartilage, adipose tissue and blood.
Therefore, we can confirm that the tissue that predominantly contains fibers that form a netlike support structure is the connective tissue.

Some foods and eating patterns may make it easier to keep obesity in check. Healthy food choices and diet patterns that help prevent heart disease, diabetes, and other chronic conditions may also help to prevent weight gain.
Eat whole foods-whole grains, vegetables, fruits, nuts, healthful sources of protein (fish, poultry, beans), and plant oils. Processed food should be minimal. Limit sugared beverages, refined grains, potatoes, red and processed meats, and other highly processed foods, such as fast food.
Deoxyribonucleic acid or DNA is a chemical that contains nitrogen and is very important for living organisms. It plays and important role in making up the genetic constitution of the cell. It is hereditary and passes from one generation to another.
DNA is double stranded helix which coils and binds to non-histone proteins to pack inside the nucleus of the cell. Every living organism contains DNA or RNA as a genetic material.
Because there is no indication of what's the highlighted structure I'm going to tell you where all the four muscles of the quadriceps femoris originate from.
The vastus lateralis originates on the greater trochanter and the lateral lip of linea aspera. The vastus intermedius originates on the lateral and anterior surfaces of the femur's body. The vastus medialis originates on the medial lip of the linea aspera and the intertrochanteric line. R<span>ectus femoris originates, </span>superior to the acetabulum, on <span>the ilium.</span>
