Answer:
CD40L
Explanation:
The CD40 ligand (CD40L) protein is a transmembrane glycoprotein which is expressed on activated T cells and belongs to the tumor necrosis factor (TNF) superfamily. The hyper IgM syndrome is caused by mutations in the CD40L gene, where the defective protein can no longer bind CD40 on antigen-presenting cells. The X-linked Hyper IgM syndrome is characterized by abnormal levels of immunoglobulins, i.e., low levels of IgG and IgA, and increased/normal levels of IgM. Because CD40L gene is located on the X chromosome, this disorder is observed much more frequently in males than in females.
Wild animal attacks should qualify as biological disasters rather than geological disasters.
Disasters generally refer to accidents that happen rather suddenly and result in widespread damages or loss of lives
- Biological disasters are disasters whose causes have biological origins such as plants, animals, humans, and microbes.
- Geographical disasters are caused by natural geographical events such as landslides, cyclones, hurricanes, volcanic eruptions, and so on.
Wild animals are biological organisms, hence, an attack from them would be a biological disaster.

Physical change only change the appearances of a substance, not it’s chemical composition. Chemical changes cause an entirely new substance with new chemical formula.
