Which best matches the description with the genetic material? a. nucleotides form a helical structure that is called a gene. (incorrect) b. chromosomes are located in the cytoplasm. c. chromosomes create genes. d. dna is located in the nucleus.

The correct answer is option d, that is, DNA is located in the nucleus.  

DNA that is deoxyribonucleic acid, is a self-replicating substance located in the nucleus and is found in almost all the living species as the prime component of chromosomes. It is considered as the carrier of the genetic information.  

It is a molecule comprising of two chains, which coil around each other to produce a double-helix carrier of the genetic data that is used in the development, growth, reproduction, and functioning of all the known living species and various viruses.  

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
