Yes, a frog's brain is less advanced than a human brain, both in terms of size and complexity. Frogs have a relatively simple brain structure that is specialized for basic survival functions, while human brains are highly developed and capable of complex thinking, problem-solving, and emotional processing.
Not if you're human. Amphibians and most reptiles have a three-chambered heart.
The frog heart and human heart are similar in that there are two atria. Each atrium brings in either oxygen rich or oxygen deprived blood from the body, pumping it to the ventricle(s).The difference between our hearts is that frogs have one ventricle while humans have two. Our human, two-ventricle system keeps oxygen rich and poor blood separated. In a frog both categories of blood are pumped into the same ventricle.It is not good for the body to mix oxygen rich and poor blood, but the frog heart has specialized ridges of tissue which help to separate the two. So, although there is some mixing, enough unmixed blood gets to the right places.The frog heart and human heart are similar in that there are two atria. Each atrium brings in either oxygen rich or oxygen deprived blood from the body, pumping it to the ventricle(s).
After the initial steps in resuscitation, a newborn is albeit with a heart rate less 100. What is the effective action to take in resuscitation
Frogs have a heart and blood vessels like all other vertebrates. The heart pumps deoxygenated blood from the body to the lungs, and then pumps oxygenated blood from the lungs to the body. However, frogs only have a three chambered heart, which permits oxygen rich and oxygen poor blood to mix. This is less effecient than the four chambered hearts of mammals and birds.
The mechanical power of the human heart is ~1.3 watts. It takes a much higher rate of energy turnover (~13 watts) to provide this mechanical power, since the mechanical efficiency of the heart is very low (less than 10%).
All amphibians have skin glands that exude toxic substances that repel predators. Leopard frogs have less than most. It would only be dangerous to a human who was particularly sensitive (allergic) or who ate a lot of them whole and raw...not terribly likely.
antibiotics make these medicines less effective?

No, a pelvic infection will not make Mirena less effective.
They are less dense than water.
The comparison of a human fist to the size of the heart is often made because both are roughly similar in size and shape, making it an easy visual reference. The heart is a vital organ, central to the circulatory system, and its health is crucial for overall well-being, which makes it a common point of focus in discussions about health. In contrast, other organs like the lungs or intestines have different shapes and functions, making them less intuitive for such comparisons. The fist analogy is particularly effective for emphasizing the importance of heart health in a relatable way.
