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:
It varies due to their polarities.
Explanation:
Remember, a membrane is a semi-permeable membrane. There are some substances that can cross the membrane and others have to take different route. It all comes down to their polarity. If we were to examine a membrane made of phospholipid bilayers, one side of it has hydrophilic heads and the inside has hydrophobic tails. The membrane is therefore polar, allowing polar substances to enter in and out of the cell. Non polar substances, such as water have to take a different route, through special proteins called aquaporins.

Answer:
A. The man's genotype is Bb. Phenotypes of the offsprings:- heterozygous brown-eyed- homozygous blue eyedGenotypes of the offsprings:- Bb- bbb. The blue is recessive, so the woman's genotype is bb. It is impossible for her to have B because it is dominant over b.c. The woman can only produce bb or blue-eyed.d. The man's genotype is Bb. It is impossible for him to produce an offspring with blue-eyes if his genotype is BB.e. The man can produce Bb or brown-eyed and bb or blue-eyed.
