When comparing the birth patterns of humans and non-human primate, Rosenberg and Trevathan discovered some very clear differences:
1. The human period of labour and child birth is exceptionally long and painful compared to other non-human primates.
E.g. a human labour can last anywhere from 10-20 hours while that of a chimpanzee lasts only 2 hours.
2. Humans have the ability to walk straight, the trade off however is that it is extremely difficult and painful to give birth to a big brained human baby.
The right answer is: Leptin
.
Leptin is a hormone closely linked to the regulation of energy consumption and expenditure: appetite, metabolism, and hunger.
A hormone is a protein with a messenger function. This means that once released into the bloodstream, she goes to another part of the body to transmit a message to specific receptors.
Leptin is manufactured in white adipocytes (adipose tissue) where triglycerides (fats) are stored and acts on the hypothalamus.
Answer:
depolarizing
Explanation:
According to my research on studies by different medical professionals, I can say that based on the information provided within the question the neuron is depolarizing. This is what happens when voltage-gated sodium ion channels are inactivated causing an increas in the neuron's membrane conductance for sodium ions.
