Answer:
a. Viral infections may lead to inflammation between the ribs (i.e., costochondritis)
b. Viral infection
c. Viral infection may lead to the influx of chemical mediators (cytokines), increased blood flow, and movement of plasma and white blood cells (leukocytes) from the blood into the injured site
Explanation:
Costochondritis is a painful condition caused by the inflammation of the cartilage that joins the ribs to the breastbone (this joint is known as the “costochondral joint”). Costochondritis is caused by inflammation of the costochondral joint, which may be triggered by multiple causes including, among others, viral/bacterial/fungal infections, exercise or strenuous activity, chest trauma, osteoarthritis, presence of tumors, etc. Acute inflammation is the immediate immune response of the body to harmful stimuli (e.g., viral infections), which is characterized by the increased movement of white blood cells (such as neutrophils and macrophages) that rapidly travel from the blood into the injured area. This plasma contains chemical mediators like pro-inflammatory cytokines which are secreted from immune cells (e.g., Th1 cells, CD4+ cells, macrophages) in order to promote inflammation.
Answer:
50% long black hair and 50% short hair
Explanation:
Attatched is a screenshot of a punnett square that shows the possibilities of the offspring having long or short hair. In short, the genetics of long black hair only need one big "L", while the genetics of short hair need to have 2 short "l"s. So when we draw the punnett square and combine the genetics, we get 50% have Llbb, and 50% have llbb
Chicken is one of the fowl and it is one of the widespread and well-known fowl. It is found in almost all area.
<u>Explanation:</u>
<u>1.Observations of the chicken leg dissection.</u>
- The main observation of the chicken leg dissection is to detect the legs of the chicken and find the muscles, tendons, leg joints and the bones
<u>2. Determine the chicken moves</u>
- Yes, the Movement of chicken can be determined .
- The chicken moves the wings by the push and the pull action with the help of the bones and it turns over the muscles until it reaches the movement.
<u>3.Characteristics of muscles in movement</u>
- The characteristics of muscles help us determine the direction of the movement are the biceps and the triceps muscles are used in the wings for the movement and the tendons attach these muscles to the bone
