Hemoglobin is a protein in red blood cells that carries oxygen from the lungs to body tissues. People with hemoglobin levels les

s than 12 g/dl are anemic. A public health official in Jordan suspects that the mean for all children in Jordan is less than 12.

Answer:The Null hypothesis state that the mean hemoglobin level for all the children in Jordan is 12g/dl.

While the Alternative Hypothesis state that the mean hemoglobin level for all the children in Jordan is less than 12g/dl

Explanation:

The Null hypothesis H0: This is the hypothesis that state that there is no statistical difference between the two variables in the hypothesis. It is the hypothesis that the researcher is work to nullify.

The Alternative hypothesis H1: This is the hypothesis that states there is a statistically difference between two variables.

An atom has at least one positive proton and at least one negative electron. Which of the following is true about the protons an
allsm [11]

Answer: Protons and electrons are far apart with lots of empty space in between.

Explanation:

Atom is defined fundamental part of a matter. Atom is composed of three sub particles protons, electrons and neutrons.

In an atom, electrons are located in orbits around the nucleus. Nucleus of an atom is located at center of the atomic sphere where protons and neutrons are present. Hence, it will be correct to say that "protons and electrons are far apart with lots of empty space in between".

How long would it take
Valentin [98]
Solution:
4.2 x 10^6 bp/10^3 bp/seconds         = 4.2 + 103 s which is 4200 seconds and equivalents to 70 minutes

In addition, assuming a pause of 2 seconds for re initiating after completing every okazaki fragment and assuming the okazaki fragments average 1000 nucleotide long.  
4.2 x 10^6 bp/10^3 bp                        = 4200 okazaki fragments                           4200 * 2 seconds                               = 8400 seconds which is 140 minutes or 2 hours 20 minutes of pauses alone.                                                                        

Therefore, overall time would be pauses plus the 70 minutes so total time of 210 minutes. Assuming that the replisome completely disassociates from the DNA after every okazaki fragment and must spend one-minute rebinding.

4200 okazaki fragments. 60 seconds rebinding time per fragment:                        4200 x 1 minute = 4200 minutes rebinding time plus 70 minutes for actual replication. 4200 minutes is 70 hours which is almost 3 days.
