It is pH. If you have a pH of 0-6 it is a acidic. If you have a pH of 7 it is neutral. If you have a pH of 8 or above it is a base.
Okay so The most serious dangers of exposure to outer space are a lack of oxygen and ebullism. Ebullism is the formation of bubbles in body fluids due to a reduction in ambient pressure. The pressure in the vacuum of space is so low that the boiling point of the fluids in your body decreases below the body’s normal temperature (37oC), which results in the formation of gas bubbles in your fluids that can really mess you up. You’ll swell up pretty bad, perhaps even up to twice your normal size, but you won’t explode as your skin is very stretchy. Your blood will also not boil. You will, of course, be in an immense amount of pain and your blood circulation will be impeded. Therefore you will die in outer space due to no oxygen and the vacuum in space. Hope this answers your question.
I think the correct answer from the choices listed above is option B. A physical property of aluminum is that it is a good conductor of heat. Other choices presented, describes chemical property of aluminum since it involves reaction which changes the substance into other form.
I think it's the first answer
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He recognized the mathematical patterns of inheritance from one generation to the next. Mendel's Laws of Heredity are usually stated as:
1) The Law of Segregation: Each inherited trait is defined by a gene pair. Parental genes are randomly separated to the sex cells so that sex cells contain only one gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.
2) The Law of Independent Assortment: Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.
3) The Law of Dominance: An organism with alternate forms of a gene will express the form that is dominant.

Answer: Other than electron microscope rest all the microscopes like darkfield,phase contrast , fluorescence, polarizing, brightfield are variations of Light Microscope. Light microscope is an microscope that is used to visualize objects not visible by naked eyes .This microscope uses light and magnifying lenses to see the objects more precisely. The main principle behind all the variations of light microscope is the light emitted that can be either polarising,bright field, or the difference in the phases as in case of phase contrast microscope. All the variations of light microscope uses light as a main source to identify and magnify objects.Electron microscope uses a beam of electron to focus on the specimen.
