Answer:
Promoter.
Explanation:
It is promoter because Promoter is a DNA sequence where's the gene transcription begins. It is the
DNA sequence which RNA polymerase binds or join to
so as to begin transcriptionn of a gene . It is a region where the regulatory elements i.e protein will bind to and the Promoter sequences are found directly upstream or at the end of 5' of the transcription initiation site. This can also encode RNA such as mRNA, trans and so on.
Prophase is the right answer
The can survive fr a long period of time outside a persons body.
Answer:
Autorhythmicity of the heart
Explanation:
It is the study of the characteristics features of the cardiac muscle cells with the ability to initiate action potential at certain level without connection to any external stimulus which the heart beats constantly and rhythmically. Cardiac muscle cells controls the rate of contraction of heartbeats.
1. Thunder is caused by the rapid expansion of the air surrounding the path of a lightning bolt. ... From the clouds to a nearby tree or roof, a lightning bolt takes only a few thousandths of a second to split through the air. The loud thunder that follows the lightning bolt is commonly said to come from the bolt itself.
2. thunderstorms mostly occur in rainforests. Some of the most powerful thunderstorms happen in the United States of America.
3. Cumulonimbus is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents. If observed during a storm, these clouds may be referred to as thunderheads. Cumulonimbus can form alone, in clusters, or along cold front squall lines.
4. The air cools as it rises. Water vapor condenses and forms cumulus clouds. When condensation occurs, heat (latent heat/energy ) is released and helps the thunderstorm grow. At some point, condensation high in the cloud (now in the form of water droplets and ice) falls to the ground as rain.
