The answer is; DNA helicase
They unzip the double helix into single strands during replication. The unzipping occurs at regions called origins where replication is initiated. The protein breaks the hydrogen bonds (using energy from ATP) between the complimentary bases of the strands hence forming a replication fork.
Answer:
D. Heart contraction and pulse are connected with one another.
E. Atrial diastole and ventricle diastole.
Explanation:
Heart construction and pulse of an individual are connected as one can hear the pulse every time contraction of the heart is completed. Pulse can be understood by this that it represents the number of the contractions is completed by heart each time.
In the pulse tracing, there are two parts of the heart that are discernible which represents the contraction of the heart that are Atrial diastole and ventricle diastole.
Mitosis is cell division in to daughter cells with the same chromosome number as the parent cell
Protects body organs and support
Answer:
With the heavy inner core, the earth's orbit and rotation will remain stable over the long term, giving us day and night and summer and winter. ... These swirling convection currents result in the earth's magnetic field which keeps us properly oriented for travel, and shields earth from deadly cosmic rays
Explanation:
The inner core is the fourth layer inside the Earth. It is a solid metallic ball made mainly of iron. Here, temperatures reach extraordinary levels, estimated to be between 7,200–8,500ºF (4,000–4,700ºC). Although the inner core is very hot, it is not liquid like the outer core.
