What is the difference between relative and radiometric dating and why is radiometric dating more accurate?
bonufazy [111]

Answer:

The main difference between relative dating and radiometric dating is that relative dating is the method used to determine the age of rock layers according to their relative depth whereas radiometric dating is the method used to determine the absolute age with the use of decaying products of the natural radioactive. Also, absolute dating is more precise than relative dating because it tells the exact age of the fossils. Both are ultimately based on the fossils found in the strata.

IRISSAK [1]

Answer:

A) Calcitonin injection

Explanation:

Parafollicular cells or C-cells of the thyroid gland produce a hormone which is involved in the regulation of calcium levels in the blood. This hormone is Calcitonin. It works in an antagonistic manner with the Parathyroid hormone (PTH). Calcitonin decreases the calcium level in the blood by increasing absorption of calcium ions in bones. In osteoporosis, when the patient is given the injection of hormone calcitonin, it produces and increase in bone mass because it negatively affects the rate of absorption of bone by the osteoclasts.

construct an explanation for the high incidence of tusklessness in the Gorongosa elephant population.
Setler79 [48]

Answer:

Argument: A trend toward an increased incidence of tusklessness will result in decreased population sizes in the

future.

Claim: In the long term, tusklessness in African elephants is not beneficial to populations, even when heavy

poaching is occurring. So, as tusklessness increases, elephant population sizes will decline.

Evidence: Although poachers kill elephants with tusks, elephants rely on their tusks for survival. Elephants use

their tusks to strip bark off trees for food and to dig up water and minerals from the ground. Male elephants

also use their tusks in competitions with other males for females.

Reasoning: Tuskless elephants are probably not as healthy as those with tusks, as they cannot eat bark off trees

and are unable to dig for water and minerals. During harsh conditions such as droughts, elephants without

tusks would be less likely to survive. Male elephants without tusks are also more likely to be injured during

mating competitions. If too many males are injured or killed, there may be a decline in reproduction.

Over time, many of the tuskless elephants will die or be unable to reproduce, so the population’s size will

decrease.
