False. Not all living things on Earth are radioactive. Radioactivity is a natural process that can be found in some elements and materials, but it does not apply to all living organisms.
False. While most organisms require oxygen for survival, there are some anaerobic organisms that can live in environments without oxygen. These organisms have adapted to use other molecules for energy production.
False. A substance is organic if it contains carbon-hydrogen bonds, regardless of whether it originated from living or non-living sources.
False. The term biodegradable refers to a substance's ability to be broken down by natural processes, such as microorganisms, into simpler, non-harmful compounds. However, a substance being biodegradable does not automatically mean it is not dangerous, as its breakdown products could still be harmful to the environment or living organisms.

False, polymers are molecules made from repeating units of identical or nearly identical compounds called monomers that are linked together by a series of covalent bonds.
true
false... it is called spontaneous generation and has been proven to be wrong.
It is true organisms have to compete for living space.
True. Biogenesis is the scientific theory that living organisms arise from other living organisms through reproduction. This theory contrasts with the idea of spontaneous generation, which suggests that life can arise from non-living matter.
No. Every living organim must have some form of interaction to operate. False. Easier for people to under stand than no.
False. All living organisms have either DNA or RNA (or both) as their genetic material. These molecules carry the instructions for the development, functioning, growth, and reproduction of living organisms.
False. Not all living things on Earth are radioactive. Radioactivity is a natural process that can be found in some elements and materials, but it does not apply to all living organisms.
A false statement about the characteristics of life could be that all living organisms require oxygen to survive. In reality, some living organisms, such as certain bacteria and archaea, are able to thrive in environments with low or no oxygen.
True. When you eat, you consume the DNA of other organisms, as DNA is present in the cells of all living things that you consume as food.
It is true that in multicellular organisms cilia and flagella are the major means of locomotion. Locomotion is one of the characteristics of living organisms.
