It is a measurement of population per unit area or unit volume.....
BASIC AND BEST :)
The correct answer is A. Heliocentric theory
Explanation:
Galileo Galilei was an Italian astronomer, mainly known for his observations that led Galilei to conclude planets revolve around the Sun (Heliocentric theory) instead of the sun and other planets revolving around the Earth (Geogcentrict theory). One of the observations that make Galilei drew this conclusion were telescopic observation of Venus, in this Galieli noticed similar to the moon Venus had different "phases" or changed its size and lighting, which was only possible if the sun was in the center of the solar system and planets revolve around it including the Earth. Thus, that Galileo was Venus changing size proved the Heliocentric theory.
Answer:
the ratio of resolution will be 
Explanation:
We have given the diameter of Telescope A is 1 meter
And diameter of telescope B is 6 meter
We know that resolution of telescope is inversely proportional to diameter of the telescope
So 
We have to find the ratio of resolution of B to A
So 
So the ratio of resolution will be
Answer:
B. All of these are drivers
Explanation:
The populations of lot of amphibians, with rare exceptions, are constantly on the decline around the world. The main reason behind this is the human activity, as it has caused lot of changes, pollution, and dangers for the amphibian populations, which has led lot of amphibians to be on the verge of extinction.
The pollution, especially of the waters, has been a major factor for the decline of the amphibian population. Lot of very toxic chemicals have made the water unsuitable for living and poisonous, which systematically killed off the amphibian populations.
The habitat loss, as with any other group of animals, has left the amphibians without places to live. They have been left without their shelters, food sources, mating grounds, and they have started to die out.
The invasive species, especially the predatory ones, have also had big negative impact. The amphibians didn't had any defense mechanism against the introduced predators, so they were easy prey and their numbers rapidly went down.
Answer:
Organic and traditional farming are fundamentally different in that conventional farming depends on chemical intervention to combat pests and weeds and provide plant nutrition. Organic farming, on the other hand, produces balanced, abundant food by relying on natural concepts such as biodiversity and composting.
