Answer: b. fossil fuels are nonrenewable, so humans will run out of them eventually. burning fossil fuels also contributes to global climate change by releasing carbon dioxide into the atmosphere.
Explanation:
Fossil fuels are limited and we will run out of them eventually. They cannot be replenished in a single human's lifespan. Fossil fuels contribute to the destruction of ecosystems, but not only that. They release carbon dioxide into the atmosphere that warms the Earth. Therefore, anything other than B. would be incorrect.
Answer:
TAAGCCATGACATGATCG
Explanation:
Transcription is the process of transfer of genetic information from DNA to RNA, typically to a messenger RNA (mRNA). During transcription, a particular DNA sequence called 'gene' is used as template to create an mRNA which is subsequently used to synthesize a protein by the process of translation. During this process (transcription), Uracil (U) bases pair with Adenine (A) and replace thymine (T) bases in RNA.
Answer:
A student visits the beach during a very hot day. She steps on the sand and jumps because it is so hot as a result of "conduction."
Explanation:
The process of the conduction happens because of the flow of kinetic energy from one molecule to the other by direct contact. When she first steps the beach on the hot sand, after that the energy moves from the hot sand to the cooler body by conduction. While walking on the sand for few time, the feet will feel hot. The movement of the heat takes place from the hot sand to the bottom of the feet by conduction. When the objects come in contact with each other the heat transfers as a result of conduction.
