Answer 1

❥︎ᴀɴsᴡᴇʀ:

1. The Universe is thought to consist of three types of substance: normal matter, ‘dark matter’ and ‘dark energy
2. It is thought that life began when lightning hit the sea. Lightning sent energy into the water . Chemicals in the sea were mixed together to form energy.New substances called amino acid were made from which life was able to growth.
3. One of the key characteristics that makes us human appears to be that we can think about alternative futures and make deliberate choices accordingly. Creatures without such a capacity cannot be bound into a social contract and take moral responsibility. Once we become aware of what we cause, however, we may feel morally obliged to change our ways. So be aware, then, that all species of apes are under threat of extinction through human activity.
4. We called wierd prine number because they are infinitely many prime numbers , there is no end.
5. There are certain ways through which we can beat the bacteria for e.g the pasteurization process, through heat shock, through the acidic treatment, Antibiotics, through the cell wall disruption with the help of chemicals like calcium chloride and at molecular level we can alter the sequences of their genome to make them useful or compatible for us

Hope this may helpful for u ☺️

ANSWERS :-

★The Universe is thought to consist of three types of substance: normal matter, 'dark matter' and 'dark energy'. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.

★We know that life began at least 3.5 billion years ago, because that is the age of the oldest rocks with fossil evidence of life on earth. These rocks are rare because subsequent geologic processes have reshaped the surface of our planet, often destroying older rocks while making new ones.

★Evolutionary biology and scientific evidence tell us that all humans evolved from apelike ancestors more than 6 million years ago in Africa. ... Apart from our obvious intellectual capabilities that distinguish us as a species, humans have several unique physical, social, biological, and emotional traits.

★Because prime factors doesn't have an end..

★A process called sterilization destroys spores and bacteria. It is done at high temperature and under high pressure. In health care settings, sterilization of instruments is usually done using a device called an autoclave.
