Explanation:
water boils at 100 degrees Celcius and freezes at zero degrees Celcius. if you want to keep water in a liquid phase, the temperature has to be between 0 and 100 therefore earth is the only planet that is able to keep water in a liquid phase as it is not too hot nor too cold
Answer: Neutral
solution
Neutral solution
have equal number of hydrogen ions and hydroxyl ions in a solution. Its pH is
naturally equal to 7 and the charge in that solution is neutral since the
concentrations are equal. In the event that the concentration is unequal, the
solution would have had a positive or negative charge.
Additionally, acidic
solutions have more hydrogen ions than hydroxide ions while an alkaline solution
contains more hydroxide ions than hydrogen ions.
Viruses may enter a host cell either with or without the viral capsid. The nucleic acid of bacteriophages enters the host cell “naked,” leaving the capsid outside the cell. ... Some enveloped viruses enter the cell when the viral envelope fuses directly with the cell membrane.
