Answer:
Q2->They all form acids when combined with hydrogen. They are all fairly toxic. They readily combine with metals to form salts.
Q3->Because their outermost orbit is complete. In Mendeleev's original periodic table there was no place reserved for noble gas. They were discovered in end of 19th century. So Mendeleev created zero group without disturbing original periodic table.

An example can be your heart, stomach, or your skin... Hope it helped! God bless you :)
Denature
as
when something causes the enzyme to change shape, thus changing shape of the active site and not allowing any substrate molecules to fit in the site and bind. Denaturation makes it so reactions don't occur between the substrate and the enzyme
Answer:
<u>Passive</u> transport
Explanation:
There are two ways molecules can get in and out of the cell. These processes are called Passive and Active transport.
Passive transport is the movement of molecules and materials from high to low concentration. No energy is needed for this process because it happens naturally.
This is in contrast to what Active transport is, where energy is needed because it moves the molecules or materials against the concentration gradient where they move from lower to higher concentration.
Answer:
A flexible connective tissue, known as cartilage varies from bones in many ways, its microcomposition is less developed in comparison to the bone and is avascular. It is not supplied with nerves and thus depends upon the process of diffusion to attain nutrients. The three kinds of cartilage are fibrous, hyaline, and elastic.
Of these the most widespread kind is the hyaline cartilage, it looks like glass. It is witnessed in embryos, where the formation of bone takes place as hyaline cartilage, which ossifies later. In adults, it is found on the tips of the ribs, on the articular surfaces of the long bones, the parts of the skull, and the rings of the trachea.
Fibrous cartilage is witnessed in the pubic symphysis and intervertebral discs and exhibits many collagen fibers.
Elastic cartilage is witnessed in the internal support of the external ear and the epiglottis and is yellow, springy, and elastic in characteristics.
