Law of Gravity and its Propounder
The Law of Gravity, one of the fundamental principles of physics, was propounded by Isaac Newton in the year 1687.
Explanation
Isaac Newton, an English mathematician, physicist, and astronomer, developed the Law of Gravity while studying the motion of celestial bodies. Here's a detailed explanation of the concept:
1. Law of Gravity: The Law of Gravity states that every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
2. Newton's Contribution: Isaac Newton's groundbreaking work on the Law of Gravity was presented in his book titled "Philosophiæ Naturalis Principia Mathematica" (Mathematical Principles of Natural Philosophy).
3. Universal Applicability: Newton's Law of Gravity is applicable to all objects in the universe, from small particles to massive celestial bodies. It explains the forces that govern the motion of planets, moons, and even objects on Earth.
4. Mathematical Formulation: Newton's Law of Gravity can be mathematically represented as F = G * (m1 * m2) / r^2, where F is the force of gravity, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers.
5. Significance: Newton's Law of Gravity revolutionized our understanding of the universe and laid the foundation for classical mechanics. It provided a unified explanation for the motion of celestial bodies and terrestrial objects.
In conclusion, Isaac Newton is the propounder of the Law of Gravity, which he presented in 1687. His contributions to physics and mathematics have had a profound impact on the scientific community and continue to shape our understanding of the universe.

Blood Groups and Compatibility
Blood groups are determined by the presence or absence of certain antigens on the surface of red blood cells. The two most important antigens are A and B, which can be present in various combinations to form different blood groups. In addition to the A and B antigens, there is a third antigen called Rh factor, which can be positive (+) or negative (-).
Universal Recipient
The universal recipient is the blood group that can receive blood from any other blood group without experiencing an adverse reaction. This is because the recipient's blood does not contain any antibodies that would react with the donor's blood antigens.
The universal recipient blood group is:
AB positive (AB+)
Explanation
When we consider blood group compatibility for transfusions, there are a few general rules to follow:
1. A person with blood group A can receive blood from donors with blood groups A and O.
2. A person with blood group B can receive blood from donors with blood groups B and O.
3. A person with blood group AB can receive blood from donors with blood groups A, B, AB, and O.
4. A person with blood group O can receive blood only from donors with blood group O.
Based on these rules, we can determine that the blood group AB is the universal recipient. This is because individuals with blood group AB have both A and B antigens on their red blood cells and do not have antibodies against either A or B antigens. Therefore, they can receive blood from donors with any blood group without experiencing an adverse reaction.
It's important to note that the Rh factor (positive or negative) does not affect the compatibility for transfusions in terms of being a universal recipient. It only becomes relevant when considering Rh compatibility for Rh-negative individuals.

Answer:
The only breed of dog that can't bark is the Basenji.
Explanation:
Here is a detailed explanation of why Basenjis don't bark:
- Basenji: The Basenji is a breed of dog that originates from Central Africa. It is known for its unique characteristics, one of which is its inability to bark.

- Reason for Not Barking: The Basenji's inability to bark is not due to any physical limitation but rather a genetic trait. The breed has a unique larynx structure, which prevents them from producing the typical barking sound.
- Alternative Communication: Basenjis are still capable of expressing themselves and communicating with their owners and other dogs. They use a combination of body language, facial expressions, and the aforementioned vocalizations to convey their emotions and needs.
- Quiet Nature: Due to their lack of barking, Basenjis are often considered a quieter breed compared to others. However, it is important to note that they can still make other noises and can be quite vocal when they want to be.
