For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it.A hypothesis is a tentative statement about the relationship between two or more variables. It is a specific, testable prediction about what you In the scientific method, falsifiability is an important part of any valid hypothesis. In order to test a claim scientifically, it must be possible that the claim...Which of the following statements is not true of scientific experiments? A hypothesis is a proposed answer to a tightly focused question; a prediction is a specific claim that follows from a hypothesis and that can be tested in an experiment.The null hypothesis and alternative hypothesis are statements regarding the differences or effects that occur in the population. When considering whether we reject the null hypothesis and accept the alternative hypothesis, we need to consider the direction of the alternative hypothesis statement.

Question Seventy four pts

Is it imaginable for scientists to review occasions that happened or animals/vegetation that lived tens of millions of years ago?

No The regulations of physics that exist as of late are not the similar laws of physics that existed in the past, so there is no technique to evaluate plant or animal fossils to those of modern organisms and deduce the function of fossilized buildings

No There is no strategy to analyze plant or animal fossils that lived tens of millions of years in the past as a result of the regulations of nature that exist lately have changed dramatically from the previous

Some antibiotics used to treat bacterial infections kill the bacteria by way of chemically punching holes in the mobile wall of the bacteria, by way of preventing the bacteria from replicating their DNA, or by means of many different movements that in the end motive cellular loss of life Why do those antibiotics not paintings to kill viruses and remedy other people of viral infections?

Viruses mutate at a rate faster than the rate at which antibiotics can paintings to kill them

Viruses are just too virulent to be killed via those antibiotics

The endoplasmic reticulum (ER) is a single membrane steady with the nuclear envelope and a chain of interconnected sacs right through the cell Why would possibly or not it's advisable to the mobile for the ER to be continuous with the nuclear envelope?

It may well be recommended for the ER and nuclear envelope to be hooked up because it would make it more uncomplicated for the ER to hold out photosynthesis

It may well be really helpful for the ER and nuclear envelope to be attached because it might make it more straightforward for the nucleus to if truth be told carry out cellular breathing

It may well be recommended because it takes less energy, DNA, carbohydrates, and phosophlipids for the ER to synthesize centrioles

It might be beneficial for the ER and nuclear envelope to be connected because it could make it easier for messages to get from the nucleus to the ER where proteins and lipids are made for the cell; this is able to perhaps require the use of much less energy
