The light-dark cycle caused by the rising and setting of the sun is responsible for what are called circadian rhythms. These are biological processes that show a cycle of around 24 hours, the time between consecutive rising of the sun. Experiments have shown that without the external cue of sunlight, the circadian rhythms of organisms tend to break down. These can be reset by being re-exposed to these cues. Jet lag is due in part to a re-setting of the circadian rhythm, as you travel to a different time zone, your body has to become used to a different timing of night and day. <span> </span>
<span>The first three scientific inquiry is being related because
they are all equivalent to the facts of finding emission.
They develop a question that must be answered.
1. The first scientific inquiry is to pose a question or else a problem is being investigated.
2. The next step is the observation, and it helps to form a hypothesis which explains the phenomenon or effect of what is observed.
Scientific inquiry is the diverse ways in which scientist study the natural world and then propose the explanations which are based on evidence which is derived from their work. Also, students develop science ideas of knowledge and understanding how scientist they do study the natural world.</span>
Cytokinesis occurs after mitosis is complete. It is when two daughter cells are formed, each with their own nuclei, after a single cell has <em>completely </em>divided.
Answer:
Yes, Since the interphase cells in G2 would have twice the DNA as the interphase cells in G1 phase or start of S phase.
Explanation:
Interphase has three stages: G1, S and G2 phase. DNA replication occurs in the S phase and doubles the DNA content of the cell. So, the DNA content of the interphase cells of the same tissue depends on stages of interphase.
The interphase cells which are in the G1 phase has half the DNA content as it is present in the interphase that has entered the G2 phase after completion of DNA replication in S phase.
Answer:
1. Nucleoid
2. Plasmid
Explanation:
Prokaryotes are groups of organisms characterized by the lack of a membrane-bound nucleus in their cell. Due to this, the genetic material (DNA) of prokaryotes are found naked i.e. not housed. The DNA of a prokaryote is arranged in a single coiled chromosome located in a region of the cell called NUCLEOID.
However, some prokaryotes e.g. bacteria carry genes on extrachromosomal pieces of circular DNA called PLASMID. Plasmids carry certain genes like antibiotic resistance genes.
