One hypothesis is that plant cells emerged as the product of an endosymbiosis between "primitive" eukaryotic cells and cyanobacteria.

Is a hypothesis a question?

A hypothesis is not a question. If you are in Jr. High or something near that, you can use the structure: If......, then.... to state your hypothesis. For example: If I place one plant in a closet and one plant in the sunlight, then the plant in the sunlight will grow faster.


Do fossils and rocks support the hypothesis of continental drift?

Yes, fossils and rocks support the hypothesis of continental drift. Matching plant and animal fossils found on different continents suggest they were once part of the same landmass. Rocks with similar ages and compositions found across continents also provide evidence for the movement of these landmasses over time.


What benefits do Animals get from plants?

Plants and animals evolved together, so it is not surprising that there are many complex plant/ animal relationships. This process of interdependent evolution of two or more species is called co-evolution. Some relationships are beneficial to both parties, while others have a clear benefit for one at the expense, or even death, of the other. Four important plant/ animal interactions are explored here: plant/ herbivore, plant/ pollinator, plant/ disperser, and other examples of mutualism.


The one gene one polypeptide hypothesis is the currently accepted hypothesis explaining how genes help to determine the phenotype of an organism?

The one gene one polypeptide hypothesis posits that each gene in our DNA encodes for a specific polypeptide or protein. Each protein plays a role in determining the traits or characteristics of an organism. This hypothesis helps in understanding how genetic information is transferred from DNA to proteins, which are key players in determining an organism's phenotype.


What is meant by saying a hypothesis must be testable?

It must be possible to observe whether the hypothesis is true.

What are some hypothesis regarding the metaphysical branch of physics?

The metaphysical branch of physics is about the philosophy of physics. Ontology is one of the most important hypothesis studying the nature of existence.


what Is a statement or claim regarding a characteristic of one or more populations?

A statement or claim regarding a characteristic of one or more populations is typically referred to as a hypothesis in scientific research. This is a proposed explanation for a phenomenon based on available evidence and predictions. It serves as a starting point for further investigation and testing.


Which of the might be a valid hypothesis for why a plant appears to be dying?

One possible hypothesis could be that the plant is not receiving enough sunlight, leading to a lack of photosynthesis and reduced growth. Another hypothesis could be that the plant is being overwatered or underwatered, causing stress to the roots and affecting nutrient uptake. Additionally, a potential hypothesis could be that the plant is experiencing a pest infestation or disease, which is impacting its health.


What laws are there in Nevada regarding the teaching of evolution and creation in school?

Nevada is pretty evolution friendly when it comes to its science standards. Nevada is also one of the few states that doesn't have a big evolution-creation controversy.


Where could one find information regarding the plant called catkin?

There are several places where someone can find more information regarding the plan called catkin. Some possible options are Wikipedia, Name That Plant and Wisegeek.


Why is evolution reffered to as a theory?

I don't exactly know why evolutionists refer to it as a theory, but I do know this. A theory is an explanation or model based on observation, experimentation, and reasoning. According to the definition of a theory, evolution is not a theory. Evolution cannot be based on observation. No one was here to observe it. So evolution should be classified as a hypothesis not a theory. It is only a guess as to how things came about.


What is the null hypothesis of a one-way ANOVA What is the alternate hypothesis?

Null hypothesis of a one-way ANOVA is that the means are equal. Alternate hypothesis a one-way ANOVA is that at least one of the means are different.

Why do scientists call evolution a theory?

Because it cannot be proven or replicated.AnswerIn science, a hypothesis is a good idea, a possible explanation, which might be right and might be wrong. Hypotheses can be refuted by experimentation. If the expectation from the hypothesis is not met by the outcome of experiment, the hypothesis is refuted. The longer a hypothesis survives unrefuted the more confidence we have in it. Evidence can support a hypothesis. The more evidence one has in support of a hypothesis, the more grows our confidence in it. Within the philosophy of science of Karl Popper, a hypothesis cannot be proven, but one can have a mighty amount of confidence in one, proportional to the amount of evidence in support of it. Unrefuted and with backing evidence, a hypothesis is promoted to a theory! A theory is better than a hypothesis. Evolution has much evidence from comparative genetics, comparative morphology and the fossil record. Evolution was once a hypothesis. Darwin collected a large mass of evidence for On the Origin of Species and now we have evidence from Mendelian genetics and comparative genetics, which Darwin knew nothing of. We now have a greater fossil record than Darwin did. There is far more evidence these days (for what is now called Neodarwinism or the Modern Synthesis- the combination of genetics and Darwin's basic 1859 ideas) than there was in Darwin's time. Evolution now has so much evidence that it is best to call it a theory, rather than a hypothesis. Yes, theories are unproven, but in Popperian philosophy of science they cannot be proven. Theories survive refutation and have much evidence and explain a lot. Biology regards evolution as its baseline, its most important idea ever. It might only be a theory of which we can only be 99% confident, but it explains everything so well that most biologists should better call it a fact rather than a theory. Evolution is such a good theory that its pedantic differentiation from 'fact' is entirely unnecessary.


What are 2 theories regarding the rate of evolution?

One theory is the punctuated equilibrium model, which suggests that evolution occurs in rapid bursts of change followed by long periods of stability. Another theory is the gradualism model, which proposes that evolution happens at a slow and steady pace over long periods of time.
