1. <span>what is the amount of the bolus dose, in both milligrams and milliliters, that you will administer in the first minute?
</span>The doses is 0.9 mg/kg and the weight of the patient is 143 pounds. So, the total doses of drug needed will be:
Total doses= 0.9 mg/kg * 143 pounds * 0.453592 kg/pound= 58.37 mg.
10% of the doses will be given bolus for 1 min, so the amount would be:
Bolus doses= 10%*58.37 mg= 5.837 mg.
In mililiters, it would be: 5.837 mg * 1ml/mg= 5.837 ml.
<span>2. what is the amount of the remaining dose that you will need to administer?
The remaining dose would be 90% of the total dose. You can either calculate it directly or subtract the bolus doses from the total doses.
Remaining doses= total doses- bolus doses= </span>58.37 mg- 5.837 mg= <span>52.533mg</span>
Answer: A scientific law is a theory that has been proven to be true everytime that event occurs, say laws of motion for example. A theory is really just a scientific hypothesis or a piece of knowledge believed to be true but not proven, its just a theory. Hope this helps, good luck!
Answer:
Following are the roles of the digestive, excretory and endocrine systems in terms of homeostasis:
- The endocrine system regulates the secretion of various hormones and homeostatic mechanisms in response to signals of the hypothalamus and pituitary glands.
- The excretory system maintains homeostasis by purifying the blood and getting rid of toxic waste from the blood.
- The digestive system is mainly involved in the transfer and regulation of nutrients from food.
Explanation:
Role of Endocrine System:
- The endocrine system mediates all the chemical signaling in the body.
- Hormones are chemical messengers that the endocrine system uses to maintain chemical homeostasis.
- Endocrine system manages glucoregulation by controlling the secretion of the hormones glucagon and insulin by the pancreas. Low and high blood sugar levels are sensed by the brain which then signals the endocrine system to release glucagon and insulin respectively.
- The endocrine system is also indirectly involved in thermoregulation. A low core temperature signal received by the hypothalamus initiates the release of TSH by the pituitary gland and then that of T3, T4 thyroid hormones that stimulate shivering thermogenesis in the skeletal muscles.
Role of Digestive System:
- The digestive system regulates the amount of nutrients absorbed in the body.
- Although the absorption of nutrients in food is not exactly according to bodily needs, the absorption of dietary iron and calcium is strictly regulated by the digestive system.
Role of Excretory System:
- The excretory system carries out osmoregulation which is the maintenance and regulation of water and salt levels in the blood.
- The excretory system regulates the excretion of toxic waste from the blood.
- Excess water, salts, urea and bilirubin (produced as a result of RBC break down) are some of the excretions.
Answer:
The correct answer will be option B.
Explanation:
Plant cell shows distinguishing features from the animal cell which can be easily observed like:
1. Shape: Plant cell is usually rectangular while the animal cell is circular.
2. Membrane : Plant cell posses two layers- outer cell wall and inner plasma membrane while the animal cell only plasma membrane.
3. Vacuole: plant cell contains a single large vacuole whereas animal cell contains small vacuole if any.
4. Ribosomes: plant cell posses more free cytoplasmic ribosomes while animal cell contains more attached ribosomes.
On the basis of this, we can predict that James is preparing a plant cell with balloon shoeing large vacuole and marbles as ribosomes.
Thus, option B is the correct answer.
