Answer: stage of fruit ripening, characterised by a surge of respiratory activity and usually coinciding with full ripeness and flavour in the fruit.
The study of tree rings is called dendrochronology. Trees produce a single growth ring each year and by studying the size and composition of each ring scientists can get information about the age of the tree, available nutrients in the area, and general climatic conditions. A relatively small ring may indicate a year when there was very little rainfall and a larger ring indicates favourable conditions for plant growth.
Ice cores hold information on past global volcanic activity and past atmospheric conditions. Tiny bubbles in the ice cores give information on the concentration of gases in the atmosphere. Ice core data plays a key role in linking the increase in carbon dioxide concentrations to present day global warming.

3. </span>The skeleton gives the body its shape, which changes with growth. In
addition to determining characteristics such as height and the size of
the hands and feet, stable body shape enables essential functions. For
example, a stable rib cage and spine enable the lungs to fully inflate
when breathing. Conditions such as osteoporosis of the spine and broken
ribs can alter the shape of the chest and impair this vital body
function.

5.Larger bones contain bone marrow, a spongy tissue inside the bones.
There are two main types of marrow, red and yellow. Red marrow is
responsible for production of all of the body's red blood cells and many
of its white blood cells. Red blood cells are produced at an average
rate of approximately 200 million per day. These cells carry
life-sustaining oxygen to the body tissues.
In adults, red marrow is found primarily in the breastbone, hips, ribs,
skull, spinal bones and at the end of long bones of the arms and legs.
Several types of white blood cells, which protect the body from
infections, are also produced in red bone marrow. Yellow bone marrow
contains primary fat cells but can transform into red marrow if the body
needs to increase blood cell production, such as if anemia develops
In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.
