Newtons first law of motion states that an object at rest stays at rest and an object at motion stays in motion with the same speed so think about it if the planets started movin faster or slower it would mess stuff up

an animal carcass had 24 grams of carbon 14 when it was alive and 3 grams when its fossilized remains were discovered how old is
KengaRu [80]
The carbon 14 left from this animal is 3 grams of 24 grams which is: 3g/24g= 1/8 times of its original mass. Then, the age of the animal fossil would be:

final weight= initial weight * (1/2) ^ time/half-live
1/8 initial weight = initial weight  * (1/2) ^ time/half-live
log2 1/8= log2 (1/2) ^ time/half-live
-3= -time/half-live
time= -3 * -(half-live)
time= 3 half-live

If the half-live is 5730 years, the age would be: 3* 5730= 17.190 years.

Bumek [7]

Answer:

The correct answer is "The common ancestor of coyotes and domestic dogs is more recent than the common ancestor of red foxes and domestic dogs".

Explanation:

One of the fastest way to known if two species have recent common ancestors is to look if they have common taxonomic ranks. In this case we can conclude that The common ancestor of coyotes and domestic dogs is more recent than the common ancestor of red foxes and domestic dogs, because the coyotes (Canis latrans) and the domestic dogs (Canis familiaris) share the same genus (Canis). The common ancestor of foxes and domestic dogs is more ancient because red foxes (Vulpes fulva) do not share the same genus has domestic dogs (Canis familiaris).

Pancreatic cells, which secrete a large amount of digestive enzymes, are labeled with radioactive leucine and then chased for se
stiv31 [10]

Answer:

On the exterior of the cell.

Explanation:

The black spots as mentioned in the given case would appear on the exterior of the cell after three hours, which suggests that the proteins or the enzymes had been discharged from the pancreatic cell. The mentioned method of labeling and then chasing the component is known as a pulse-chase experiment.  

In this experiment, the labeled compounds are used to follow the dynamics of cellular pathways and procedures. The molecules in a cell get produced and degraded spontaneously at various rates. These changes in the localization of the molecule and its expression levels with time can be determined by exposing or pulsing cells to a labeled compound.  

After this the cells are exposed sequentially to the same compound unlabeled, the process is termed as the chase. The compounds are generally labeled with fluorescent dyes or radioisotopes.
