Answer:
1. spontaneously
2. resting potential
3. action potentials
4. pacemaker potentials
5. K+
6. Na+
7. into
8. Ca+
Explanation:
Pacemaker cells (also known as sinoatrial node cells) are cells that generate rhythmic impulses and set the pace for blood pumping in the heart. These cells have the ability to rhythmically depolarize and initiate action potentials. In pacemaker cells, Ca2+ and Na+ levels are higher in the extracellular environment, while K+ concentration is higher intracellularly. The pacemaker action potentials have three phases: 1-depolarization, where membrane potential reaches -40 mV and voltage-gated Ca2+ channels open, 2-repolarization, where voltage-gated Ca2+ channels close and voltage-gated K+ channels open, and finally 3-gradual depolarization, which is caused by the slow influx of Na+ ions.
Answer:
1. 45.9 to 62 kg.
2. 82.72 %
Explanation:
1. We have to find out Mr. Swanson's body weight by calculating his body mass index.
From body mass index or BMI = weight of the person in kg / height in meter
BMI = 41.36/ 1.5748
= 41.36 /2.47999504
= 16.67
The normal range of BMI is 18.5 to 24.9. So, Ms. Swanson's desirable body weight would be 45.9 to 62 kgs.
2. Mr. Swanson's percent ideal body weight:
= 
Now calculating the ideal body = 45.5 kg + 2.3 kg for each inch above 5 feet
Ideal body weight (IBW) = 45.5 + 2.3 x 2
= 50 kg
Now calculating the percentage ideal body weight
= 
= 0.8272 x 100
= 82.72 %
The normal range of percentage ideal body weight lies between 90 - 100 percent. Thus, the percentage ideal body weight of Mr. Swanson is low.
3. Some of the physical signs that can be seen in the patient when the patient is dehydrated are :
i). Dry skin
ii). weight loss
iii). thirsty
iv). pale skin color
v). fatigue
vi). tiredness
vii). dizziness
4. The transthyretin of Mr. Swanson is quite low and it indicates malnutrition. His transthyretin is about 15mg/dl. Thus he require proper diet planning and modifications.
5. Mr. Swanson must take in high calorie food and should consume plenty of water. She should also include fibers in her food intake. Mr. Swanson should consult a nutritionist or a dietitian who could properly guide her and make a food chart that includes daily intake of nutritious and protein rich food.
6. For increasing the food intake, Mr. Swanson must follow a healthy diet. He should take small servings but many times a day. Also exercising and drinking plenty of water will increase his food intake and will keep him healthy.
Answer: B. Encouraging athletes to have children together
Explanation: The history of reproductive genetics is complex. During the early part of the last century, eugenics programs were popular. Eugenics is a science that deals with “improving” hereditary qualities. Positive eugenics encourages reproduction by those considered genetically superior. In Nazi Germany, “Pure Aryans” were encouraged to breed to create a superior race. Negative eugenics limits or discourages reproduction by those considered genetically inferior. In the United States, negative eugenics led to laws requiring the involuntary sterilization of thousands of people due to mental or physical handicaps. Events such as these have led people to question the value of eugenics. PF
If you're comparing it to physical bullying then:
Cyber bullying, though digital, can still have a lasting effect on a person's emotional state. Even if it is not face to face, the person will still feel the intended way of the bully.
Physically bullying includes fighting someone head on and can cause physical damage. While Cyber Bullying doesn't start off as physical, it can encourage others that are close to you to physically bully you.
Cyber bullying and physical bullying both are intended to make the other person feel bad most likely because they feel bad themselves.
Cyber bullying and physical bullying both typically don't have a genuine reason for it's occurrence.
Hope this helped! Sorry if I took the question the wrong way!
