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.

What happens to the states of matter when the temperature changes
stepladder [879]

    They may either release heat or gain heat. With a temperature increase, the kinetic energy increases and the state of matter will increase (example, ice to water aka solid to liquid)

    If the temperature decreases, then the kinetic energy decreases and the state of matter will decrease (example, water vapor to water aka gas to liquid)

Have a nice day!

    I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

The chromosomes of offspring are not identical to those of their parents or siblings because ______ is shuffled during meiosis.
tigry1 [53]

The chromosomes of offspring are not identical to those of their parents or siblings because <u>genetic information</u> is shuffled during meiosis.

Meiosis can be described as a cell division process by which gamete cells divide. The number of chromosomes is reduced to half in this cell division process.

During the process of meiosis, genetic information is shuffled between non-sister chromatids of the homologous chromosomes. This shuffling process is referred to as crossing over. A new combination of alleles is formed due to the process of crossing over.

It is due to the process of crossing over that the organisms produced are not identical to each other or the parents. Genetic diversity is important in order for populations to survive which is possible through the process of meiosis.

What is a change in a DNA sequence called
Shkiper50 [21]
Mutation. this happens when a cell copies its DNA to divide. its more common than you may think, a "typo" occurs every 100, 000 or so nucleotides, thats about 120, 000 "typos" every time a cell divides.

Why do you think a small surface area to volume ratio would cause a problem?
Scilla [17]

Answer:

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.
