A week or thereabouts. Once it dries out completely, the smell will be gone.
By using relative age. Over a long period of time, sediment will, layer by layer, coat and cover the fossil, making it difficult for paleontologists and scientists to figure out how old the fossil really is.
Your Oscar can not get pregnant. It is an egg layer. It will not be adult or mature until it is around 6 inches long.

brown snakes get to about 1.5 metres long so an adult brown snake gets to about that long. I'm not completely sure though.
She'd spent too long in the sun and damage to her epidermis was evident. The amount of melanin in the epidermis is the reason for the many variations in human skin color. Some of my friends have tattoos but I think I'd rather leave my epidermis the way it is.
Calculating the age of the top and bottom of the layer
My dictionary give this definition - - the normal investment of bone, consisting of a dense, fibrous outer layer, to which muscles attach, and a more delicate, inner layer capable of forming bone.
On the outer surface of the compact bone is a layer of connective tissue.
The time it takes for a thick layer of sedimentary rock to form can vary significantly depending on various factors, such as the depositional environment, the rate of sedimentation, and the type of sediment being deposited. In general, it can take anywhere from a few hundred to millions of years for a thick layer of sedimentary rock to form.
Periosteum is a membrane that lines the outer surface of all bones, except at the joints of long bones.Endosteum lines the inner surface of all bones.Periosteum consists of dense irregular connective tissue. Periosteum is divided into an outer "fibrous layer" and inner "cambium layer" (or "osteogenic layer"). The fibrous layer contains fibroblasts, while the cambium layer contains progenitor cells that develop into osteoblasts. These osteoblasts are responsible for increasing the width of a long bone and the overall size of the other bone types. After a bone fracture the progenitor cells develop into osteoblasts and chondroblasts, which are essential to the healing process.
Oxygen. Nitrogen also helps ozone form (as long as water vapor is not around).

They study how long to get to planets and if there is life in outer space.
Waxy layer on outer surface of green plants is called cuticle .This cuticle is actually present in outer cell walls of epidermal cells . The wax present in cuticle is a type of lipid . It is waterproof layer which prevents excessive loss of water by transpiration . It also protects plant from abrasive damage. Wax is chemically a mixture of esters of long chain fatty acids eg cerotic acid , montanic acid , long chain alkanes , alcohols , ketones .
how long does it take to grow a new layer of skin
The outer planets take longer.
