The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.
Answer:
8A
Explanation:
I= Q/t, where
I= current (A)
Q= charge (C)
t= time (s)
First convert the time from minutes to seconds.
1 minute= 60 seconds
2 minutes= 2×60= 120 seconds
Using the formula,
I= 960÷120
I= 8A
Answer:
A.The weak force acts within protons and neutrons, and the electromagnetic force has an infinite range.
Explanation:
Weak force explanis the interaction among subatomic particles (e.g. protons and neutrons) and is directly involved in the radioactive decay of the atoms. This is the reason that it has been well studied to understand nuclear fission reactions. Its range is very limited and does not exceeds beyond subatomic particles.
On the other hand, electromagnetic force is a very strong force that holds atoms together. It has infinite range. Once can assume the strength of this force from the basic understanding that, within an atom, electrons and protons exist together despite of their opposite charges. Nevertheless, the integrity of atom is not disturbed.
Answer: B. Pathways by which matter is transferred between organisms and the environment
Explanation:
Biogeochemical cycles can be define as cycles which involves the natural pathways by which inorganic and organic matter is transferred within the living organisms and the environment.
The essential elements such as water, carbon, phosphorous, nitrogen and oxygen are transferred among the various spheres of the earth like atmosphere, biosphere, lithosphere and others which forms the integral part of the non-physical environment.
Major neurocognitive disorder due to vascular disease. The dementia is the medical word for a group of indications that point on the way to a disruption of assured brain activities that fall largely under conscious control and help define each one of us as unique human beings. In line with these variations, vascular dementia is now recognized as major vascular neurocognitive disorder.
