Answer:
Keratinocytes are the predominant cell type of epidermis and originate in the basal layer, produce keratin, and are responsible for the formation of the epidermal water barrier by making and secreting lipids. Keratinocytes also regulate calcium absorption by the activation of cholesterol precursors by UVB light to form vitamin D The significance of the VDR is that stimulation of it plays a role in the proliferation of the stratum basale and differentiation of keratinocytes as they move upwards in the epidermis. The exocrine functions of the skin are by way of the sweat and sebaceous glands. Another important role of the skin is a sensation to touch, heat, cold, and pain by the actions of the nociceptors. The general appearance, turgor, and other qualities also give insight into the general health of the body.

Answer:
ECG paper is a grid where time is measured along the horizontal axis.
Each small square is 1 mm in length and represents 0.04 seconds.
Each larger square is 5 mm in length and represents 0.2 seconds.
Voltage is measured along the vertical axis.
10 mm is equal to 1mV in voltage.
The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form
Heart rate can be easily calculated from the ECG strip:
When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.
For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).
The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.
For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).
Answer:
1 unit.
Explanation:
According to nutrition information provided by the USDA, 0.25 cups of Granola contain roughly 14 grams of carbohydrates. Since Sue needs to take 1 unit of insulin for every 15 grams of carbohydrates, her parents should prepare to inject her with 1 whole unit for her afternoon snack.
