Explanation:
Over its lifetime, a low mass star consumes its core hydrogen and converts it into helium. The core shrinks and heats up gradually and the star gradually becomes more luminous. Eventually nuclear fusion exhausts all the hydrogen in the star's core
Hello!
A polar molecule is where one of the atoms in a molecule has a slight positive charge, and another has a slight negative charge, due to the unequal sharing of electrons.
Water is one of these molecules - the electrons spend more time around the oxygen atom in the center, and less around the hydrogens, so the hydrogen atoms have a slight positive charge, and the oxygen a slight negative.
Therefore, your answer is B, water has a slight negative and a slight positive charge at opposite poles.
Hope this helps!
Answer:
Articular articular cartilage is very important part of the long bone structure. It is present between the bones at the joints and help in reducing the friction between the joints. the epiphytes is data present at the end of the long bones are usually have a covering of the articular cartilage and it has a very thin layer of cartilage that helps in reducing the friction .
It also act as a shock absorber between the two bones and helps in the transmission of force from one phone to another and divide the force across the skeletal system. It also transmit the force on the bones with low fictional coefficient. The articular cartilage are very susceptible and prone to the injury and it lacks blood vessels and nerves. Articular cartilage is made up of hyaline cartilage and is made up of densely packed extracellular matrix which certain type of specialised cells known as chondrocytes. It is also made up of water , collagen , proteoglycans and glycoproteins .

cause the less the vapor the more the direct heat
This is absolutely false.
There is a wide diversity of life teaming around hydrothermal vents. These communities include primary producer organisms, but instead of obtaining energy from the sun, these bacteria use a process called chemosynthesis to convert minerals and other chemicals in the water into energy. These bacteria support a wide range of other animal species, including giant tube worms, deep sea mussels, serpulid or “feather duster” worms, and vent crabs, the apex predator of the vent community.
