Answer: air mass
Explanation: An air mass is a large body of air with generally uniform temperature and humidity. The area over which an air mass originates is what provides its characteristics. As such, air masses are associated with high pressure systems.
As altitude increase the air pressure decreases
yes, because it is in bloodline
Answer:
an asteroid impact
Explanation:
The asteroid that formed a crater located on the edge of the Yucatan peninsula thought to be responsible for the mass extinction of dinosaurs.
Answer:
a. Damage is caused by free radicals that slow down the cell-duplication process.
c. Aging may be caused by the inevitable loss of the ability of cells to duplicate perfectly.
Explanation:
The free radical theory of aging states that aging is caused by accumulation of damage inflicted by reactive oxygen species (free radicals). It proposes that organisms age because they accumulate oxidative damage, Now,this damage comes from reactive oxygen species (ROS), which are partially reduced metabolites of molecular oxygen (free radicals) generated as products of metabolic reactions. Thus, these free radicals cause damage that slow down the cell-duplication process.
Also, Aging may be caused by the inevitable loss of the ability of cells to duplicate perfectly. (SENESCENCE).
When senescence occurs (i.e inevitable loss of the ability of cells to duplicate perfectly) there is progressive deterioration of physiological function, an intrinsic age-related process of loss of viability and increase in vulnerability of cells.
