Answer:
The interaction between cellulose-digesting organism in the gut of a termite and the termite is +
Explanation:
This relationship that exists between termites and the organisms present in their gut that are capable of degrading cellulose is a relationship called mutualism. Mutualism is part of the biological interactions in which both organisms benefit from the coexistence of both. For this reason this relationship would be positive.
The food of termites is wood, but they cannot produce the enzymes they would need for degradation of the wood. Thanks to this, there are small organisms called protozoa that are found in the intestine of the termites that allow them to degrade the cellulose present in the wood, these organisms help them to degrade the cellulose that by themselves they could not do since termites do not contain the cellulose enzymes responsible for cellulose degradation .In this way TERMITES can get what they need to perform its metabolism and biological functions.
Answer:
In 1864, while working at Glasgow University as Professor of Surgery, Lister was introduced to Pasteur's germ theory of disease, and he decided to apply it to the problem of surgical infections
The nurse suspects that an older adult patient has features of basal cell carcinoma appearing in form of a small dome-shaped lesion with a pearly surface on the face.
What is Basal cell carcinoma?
The most prevalent type of skin cancer that is not melanoma is basal cell carcinoma (BCC).
- It is a tumour that causes localized damage and has a variety of clinical and histological characteristics.
- When viewed at low power magnification, a basaloid epithelial tumour emerging from the epidermis is the primary characteristic of basal cell carcinoma.
- Normally, the palisade-like basaloid epithelium forms a fissure from the surrounding tumour stroma.
The nuclei grow congested in the centre, with scattered mitotic figures and visible necrotic bodies.
The presence of a mucinous stroma serves as a helpful distinguishing factor from other basaloid cutaneous tumours. Additionally, some tumours may exhibit foci of regression, which are regions of eosinophilic stroma devoid of basaloid nests.
Hence, the answer is a small dome-shaped lesion with a pearly surface on the face.

Answer: Option D. "Heme"
Explanation:
Deoxyhemoglobin can be defined as a form of which has no oxygen binded to the hemoglobin.
When deoxyhemoglobin is replaced with oxyhemoglobin then the oxygen binds to the heme component of the hemoglobin protein in red blood cells.
Each heme group has iron atom that has the ability to bind to oxygen (02) molecule.
Four oxygen molecules bind to a single hemoglobin protein.
Hence, the correct answer is option D "Heme".
