Compare and contrast a hypothesis and a theory

Answers

Answer 1

Answer: A hypothesis is proposed explanation that's made on the basis of limited evidence as a starting point for further scientific investigation.

A theory, and I suppose you're referring to the scientific theory, is a well-substantiated explanation for some aspect of the natural world. It's based on a large body of facts that have been repeatedly confirmed through extensive observation and experiment.

Answer 2

Answer: Compare and Contrast Theories and Hypotheses. A hypothesis is a possible scientific explanation of an observation or set of observations.

A gardener crosses tall true–breeding pea plants with short true–breeding ones. Tall plants are dominant to short ones. He collects the seeds to grow F1 plants and then allows them to self–pollinate to form an F2 generation. Which of the following describes the traits of the offspring correctly?

Answers

If the parental plants (P-generation) have the genotypes TT (tall) and tt (short), respectively, all the F1 plants will be tall heterozygotes (genotype Tt).

>Those Tt-plants will (statistically) have the following distribution of genotypes and phenotypes among their offspring (the F2 generation): 25% TT (tall homozygotes); 50% Tt (tall heterozygotes) and 25% tt (short homozygotes).

>In other words: 3/4 of the offspring will have the tall phenotype (genotypes TT and Tt); and 1/4 will be short plants (genotype tt). -

Which cell structure is correctly paired with its primary function? 1. ribosome–protein synthesis 2. mitochondrion–movement 3. vacuole–cell division 4. nucleus–storage of nutrients

Answers

Answer:

1. Ribosome–protein synthesis

Explanation:

Ribosomes are structures that are floating in cytoplasm and can be found attached to the endoplasmic reticulum. Ribosomes are also called as the protein factory of the cell because their foremost function is the protien synthesis. Proteins are required by the cell for basic cellular functions, cell division and damage repair etc.

By locating active __________, geologists determine the likelihood of earthquakes in a region

Answers

By locating active faults, geologists can determine the likelyhood of earthquakes in a region. A fault is a crack in the earth's surface along which movement occurs. Movement along faults cause earthquakes. Seismologists use various intruments such as GPS and seismographs to monitor movement along faults to attempt to predict the likelihood of a quake.

The word that would best complete the sentence, "By locating active ____, geologist determine the likelihood of earthquake in a region", is fault line. The presence of the fault lines increased the risk of a certain area to the disasters such as earthquake when there is a movement underground.
