Lack of light and animals affect the rate of photosynthesis
Answer:
d. Measure thyroid-stimulating hormone level
Explanation:
The most suitable next step in management of this patient is to measure a thyroid stimulating hormone, or thyrotropin level.
This patient's apparent treatment refractory dyslipidemia is most likely contributed by undiagnosed thyroid disease. Despite sticking to the treatment with atorvastatin, his LDL AND total cholesterol are raised.
Additionally, there are some clinical signals that give an idea about the diagnosis of hypothyroidism especially fatigue and constipation.
Hypothyroidism is concerned with and is a very common secondary cause of dyslipidemia and thyrotropin level measures are indicated.
Hyperlipidemia may show better results to thyroid stimulating hormone.
Hence option D is the right answer.
Explanation:
To protect the animals, plants, and more. Without having the habitats they'll die/go extinct. The plants will soon rot/wither away.
<h2>The given statement is true</h2>
Explanation:
Iron absorption occurs in the duodenum and upper jejunum of small intestine
- At physiological pH ferrous iron is rapidly oxidized to the insoluble ferric form
- Gastric acid lowers the pH in the duodenum which enhances the solubility and uptake of ferric iron
- Once iron gets inside the enterocyte it can be stored as ferritin;Ferritin is a hollow spherical protein which helps in storage and regulation of iron levels within the body
- Ferritin molecule have ferroxidase activity which helps in the mobility of Fe2+ out of the enterocyte by ferroportin
- Transferrin is the major iron transport protein which transports iron through blood
- Fe3+ binds to transferrin so Fe2+ transported through ferroportin must be oxidized to Fe3+
- Fe2+ needs to be oxidized first so that it can be transported through ferroportin
- Once iron gets inside the cell it can be used for various cellular processes
