To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7 neutrons
Answer:
C, birthrate exceeds death rate
Explanation:
If emigration were to exceed the birthrate, the population would decrease due to so many people leaving and with the birth rate getting lower due to so.
If the death rate exceeded the birthrate, people would be dying all over and no babies would go "goo goo ga ga" because they're probably dead.
If death rate exceeded the immigration rate, then people would just be coming to a country just to die. Like, who would want that?
So yeah, it's C.
The correct answer is C. It is reliable because the article is based on multiple studies done by scientists at multiple veterinary schools.
Explanation:
Information is considered as reliable if it is supported by evidence and the author is an expert in the field. According to this, the information about the Labrador Retriever in the encyclopedia is reliable because it is based on multiple scientific studies and articles that likely used evidence such as tests, observations, among others. Besides this, the studies were done by scientists at veterinary schools, which are considered to be experts and authorities in the field of dog breeds. Thus, this source "is reliable because the article is based on multiple studies done by scientists at multiple veterinary schools."
Answer:
to maintain homeostasis
Explanation:
The bionic pancreas is a technology created to reduce and adjust blood sugar levels in patients with diabetes. This external device was developed by Ed Damiano's lab at Boston University. This management system is well known to maintain homeostasis by managing blood sugar levels: the bionic pancreas contains two pumps, one with insulin and the second one with glucagon for controlling the sugar levels when they change in the blood.
