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:
Only the extracts from heat-killed cells treated with RNase are unable to transform nonvirulent bacteria into virulent bacteria.
Explanation:
The experiment by Avery, McCarty and MacLeod aimed to identify Griffith's "transforming principle," which is a principle that explains how transformation is a way of recombining, exchanging, or transferring genetic information between organisms or from one organism to another. For this, they used cell that were heat inactivated and purified the transforming principle of these cells.
The purified cells did not give positive results in the tests done by the scientists, but they presented transformants very similar to the DNA. However, Avery suspected that the result should be reinterpreted and that the molecule was not a DNA. This is because RNA degrading enzymes had no effect on the transforming principle and only RNase-treated heat-killed cell extracts are unable to transform non-virulent bacteria into virulent bacteria.
Answer:
As more people rush into the hospital, less spave willl be available depedning on where they are placed, what happened, and what care is needed. If there was a fire, there would be alot of people with burns or smoke inhalation causing the hospitals disatser response to take act differenetly instead if there was an epidemic where people are sick but not usually physically harmed.
Explanation:
What your brain says about the object's distance is Nothing - this is a visual pattern recognition test, not distance. The size of the object and the distance it is from the observer determine the size of the image that forms on the retina.
- Nothing - this is a visual pattern recognition test, not distance.
<h3>How does the image arrive on the retina?</h3>
After the pupil, the image reaches the lens and is focused on the retina. The eye's lens produces an inverted image, and the brain converts it to the correct position. In the retina, more than one hundred million photoreceptor cells transform light waves into electrochemical impulses, which are decoded by the brain.
With this information, we can conclude that The size of the object and the distance it is from the observer determine the size of the image that forms on the retina.
