Answer: True
Explanation :
There are a large number of microorganisms that are present in the soil which plays an important role in making the soil rich in nutrients.
The degradation of the organic matter present in the soil is done by the action of several enzymes released by these microorganisms and hence, this leads to the release of several nutrients into the soil.
b. news about a scientific discovery reaches the public sooner.
c. only the most exciting experiments are published.
d. a hypothesis is accepted without any supporting evidence.
Answer: A. A scientific paper is a reliable source of information.
Explanation:
A peer review is a kind of analysis of the research outcome by the people who generally exhibit the same competency as that of the author or researcher and knowledge for a particular subject or topic in which the research has been conducted. Such a process makes the research outcome more authentic and reliable. The author learns to improvise the research process and corrects the mistakes after the peer review.
Answer:
The correct answer is : A scientific paper is a reliable source of information.
Answer:
The variables are the factors, which do not have a fixed value. Their value keeps changing in an experiment. It can be divided in two types: dependent variable and independent variable.
The dependent variable in the experiment is the variable, whose tendency to vary depend on other factors. To test this hypothesis, the rate of photosynthesis with respect to different wavelengths. So, the dependent variable is rate of photosynthesis, as it is dependent on the wavelength of the light.
This is a symbiotic relationship between the Boxer crab and sea anemone.
The symbiosis is a type of relationship between two species which has benifit for both the participating organisms.
Here in case of boxer crab, the crab gets the help from the sea anemone in the form of protection. The sea anemone chases the predators and thereby saves the organism from being hunted.
On the other hand, the sea anemone gets food from the crab's prey which he hunts.
So there's a benifit for both.
