Ans: maintain homeostasis
Homeostasis is any
self-regulating process by which biological systems tend to maintain stability
while adjusting to conditions that are optimal for survival. It is the stable
state of an organism and of its internal environment. Maintenance of
homeostasis usually involves negative feedback loops. These loops act to oppose
the stimulus, or cue, that triggers them. The stable condition is the condition
of optimal functioning for the organism, and is dependent on many variables,
such as body temperature and fluid balance, being kept within certain pre-set
limits.
Gorillas are a predator. They eat food and rarely ever get killed for food. But if we take away their habitat by making buildings and houses then they will die for other causes like hunger. If the gorillas go extinct then the food change will get all messed up. The food they normally eat will over populate meaning the food gorillas eat (like fruit) will over populates and take over the area. That means it will start to take up the space that other plants need to grow. The other plants that other animals will need to eat will slowly start moving away because their food is dying. They will start to go somewhere else and mess up that habitat too. Those animals will eat the food needed by the animals that lived there originally and food will become scarce for animals that all need the same type of resources.
Answer:
B. 26amu
Explanation:
The nucleus of an atom in an element contains protons, electrons and neutrons. The proton number equals the electron number in a neutral atom. The proton number is also called the atomic number, denoted by Z.
The mass number also called Atomic mass unit (amu) in this case, of an element is the sum of the proton number and the neutron number in the atom of that element. The mass number is denoted by A.
Hence, A = Z + N
Where A = Mass number
Z = Proton (atomic number)
N = Neutron number
In this question, N is 11 while Z is 15
Hence, the mass number of the element in the question, in AMU, is 15 + 11 = 26amu.
