Ice does not need to melt into liquid water before it can return to the atmosphere as water vapor. tf

The answer is true.

Hope this helps

True.

Explanation:

The ice can become water vapor without having reached the first liquid phase. This process is called sublimation and consists of the passage of a solid to the vapor state without first passing through the liquid state, that is, as the dry ice is heated, it is transformed directly into water and not liquid water.

When heat is supplied to an ice body (0 ° C), for example, the temperature remains constant until the ice melts. The energy is used to break up the internal crystalline structure of the ice and melt it. If that heat is high enough it can turn the ice directly into the water vapor.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
