How do observations relate to hypotheses? check all that apply. observations leading to a hypothesis come from prior knowledge or research. observations leading to a hypothesis come from the same experiment. a hypothesis is formed based on observations from many experiments. a hypothesis is formed after making observations but before performing an experiment.

The correct answer is A hypothesis is formed after making observations but before performing an experiment.

Observation refers to a careful study of phenomena with the intention of deriving a logical explanation for such phenomena.

In scientific study, research begins with an observation. The observation of a given phenomenon leads the research to draw up a plausible explanation for the observation called a hypothesis.

This hypothesis becomes the guide for experimentation. The experiments are expected to confirm or disprove the hypothesis.

Hence, a hypothesis is formed after making observations but before performing an experiment.

A hypothesis is formed after making observations but before performing an experiment.

Observation is a statement that is based on something noticed or observed. First we observe something and then make hypothesis. Hypothesis is a statement that can be true or false after performing an experiment. Hypothesis can be made on the basis of observations and at that time no experiment was performed so we can conclude that hypothesis is made from observation before performing an experiment.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
