How is the theory of evolution an example of a scientific theory?
Scientific method is an empirical method of knowledge acquisition, involving careful observation, formulating hypotheses based on such observations, testing deductions drawn from the hypotheses, and refinement or rejection of hypotheses based on the results of the tests.ext we have to know what “theory of evolution” we’re talking about. Let’s begin with the theory proposed by Charles Darwin in the Origin of Species.
I don’t know what “No assumptions here” in the question details is supposed to mean. Making hypotheses is part of the scientific method. Maybe it means that a hypothesis is assumed subject to verification, while an assumption is an axiom not subject to test. The scientific method makes testable hypotheses but never makes firm assumptions.
Darwin made a lot of observations. Then he made two hypotheses:
The observed variation among individuals can accumulate to produce all the differences we observe among species.
The effect of these variations on the ability of a living entity to survive and reproduce preserves some variations and eliminates others.
The heritability of variations was essential to the theory, but it was an observed fact, not an assumption or a hypothesis.
Because Scientific method is an empirical method of knowledge acquisition, involving careful
Natural selection operates on populations over many generations. Which of the following allows natural selection to occur?
the unequal ability of individuals to survive and reproduce
Answer:the unequal ability of individuals to survive and reproduce
How can glaciers cause deposition

Which units are used in a pyramid of biomass?
or are the units used in a pyramid of biomass
Each tropic level in the pyramid measured in units or . The biomass can also be measured in the form of energy i.e. . A pyramid biomass is the graphical illustration of the biomass present in the unit area of various level.
Two different types are pyramid are there, one inverted pyramid( shown in pond ecosystem, with mass of phytoplankton's-producers are lower; and than the heterotrophs- fish and insects) second one is upright one; in which the weight of producer is more than the consumers.
What is indirect contact
Indirect contact transmission occurs when there is no direct human-to-human contact.
There are two types of contact transmission: direct and indirect. Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person. Indirect contact transmission occurs when there is no direct human-to-human contact.
How does the grand canal promote transport of goods in China
The Grand Canal is the longest canal in the world. It is also a famous tourist destination. The canal was first constructed during the Sui dynasty. The King Fu Chai of Wu ordered the digging of the canal between the Yangtze and the Huaihe River for the purpose of transporting troops to launch an attack on to the state of Qi. In 605 A.D., emperor Yang Di established the Eastern Capital in Luoyang and this is how the trasport of goods was promoted in the Grand Canal.
