Answer:
botanist sees that some of her orchids with a black fungus growing on their leaves also have small rotting spots, while other orchids in the atrium that lack the fungus appear healthy. What is the most likely conclusion the botanist can make about the virus
The correct answer is (b) Jupiter has mass less than that of sun which cannot generate enough pressure which can start hydrogen fusion. Jupiter has similar composition as both are entirely made up of hydrogen and helium. They both differ in the core and mass. The mass of Jupiter is so small as compared that it would not be able to generate enough pressure to start hydrogen fusion. Jupiter's core is made of metallic hydrogen and the core of sun is so hot that the hydrogen splits into electrons and protons. This generates hydrogen fusion.
Thus, Sun a star and Jupiter is not a star.
Answer: B. evaporation, condensation, precipitation
Explanation:
The cycle that ensures that fresh water is available is called the Hydrological cycle and it involves several key processes.
As it is a cycle, none of the processes can be considered first but if any could, it would be evaporation. This is when water on the surface is heated and becomes water vapor (gas) and rises towards the atmosphere.
Condensation occurs as the water vapor rises because the further up you go, the colder it gets. These water vapor particles will thus condense and clump together to form clouds.
These clouds keep getting larger until they are too heavy to be carried by the atmosphere in which case they fall to the ground as rain the process known as precipitation.
Answer:
Ecology is the study of environment and biology is study of plant and animals.The interrelationship between an organism and environment
Explanation:
Ecology is the study of organisms, its distribution, abundance,interrelationship with another organism and the interaction of organisms with their environment in which they adapt to survive.
Sunlight is the main source of energy for living beings on earth. Movement of energy flow and nutrient cycle plays a significant role in living beings.
In ecology there are different levels of organization such as species, population community,ecosystem,biome and biosphere.
There are different cycles which an organism required to survive, carbon cycle, nitrogen cycle, oxygen cycle, phosphorous cycle, and of course the most basic thing to survive is the water cycle. All these cycles coming under one term called the biogeochemical cycle.
The ecological pyramids such as pyramids of an ecosystem, pyramids of number pyramids of energy flow and pyramids of biomass based on these pyramids living things survive.
Rachel Carson's warning in silent spring was focused on : The misuse of pesticide
The book was published in 1962 and documented the effect of the use of pesticide to the environment
