Answer:
DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide. The sugar is the 3' end, and the phosphate is the 5' end of each nucleiotide.
Answer:
TRUE
Explanation:
In the cardiovascular system, the blood flows from <u>high pressure to low pressure.</u>
In the ventricular ejection phase, when the muscles of the ventricles contract, the<u> pressure gradient in ventricles rises</u>. This increases in the <u>pressure in the ventricles exceeds the pressure in the pulmonary artery </u>and aorta, thus opening pulmonary and aortic valves and ejecting the blood from the heart.
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.

Approximately 74 percent of adults in the United States are overweight. BMI
is known as body mass index and it is calculated by
BMI= weight/height
BMI = kg/m²
Body mass index helps to determine if a person is overweight or
underweight. Being over weight means having a BMI of 25-29.9 while
having below 18.5 means being underweight.
Recent studies have however shown that approximately 74 percent of adults
have a BMI of greater than 25 which means they are overweight.
