Answer: Oxygen atom has 8 Protons
Explanation:
Oxygen atom (O) has an atomic number of 8, and a mass number of 16.
Recall that atomic number of any element is equal to the number of protons in its electronic shell, hence, the number of protons in oxygen atom is also 8
Answer:
C. Go through a step called metaphase.
Explanation:
In plant and animal cells metaphase is a step they both share.
Streams or rivers form when water that does not find an underground aquifer, drains off the land by either seeping through the soil or spilling over the surface into the river or stream bed.

4.
Explanation:
In trial A, people have no immunity so there are more chances of infection and in trial C, only 50% of people have immunity so chances of infection are less, so infection will spread faster in trial A than trial C.
If compared, trial C will have less infected people than trial A because people in trial A has no immunity and people in trial C have 50% of immunity, so only fewer people will get infected even after six point of contact.
As percentage of immune people (trial C) is 50, so there are equal chances of immunity and non-immunity. there are three reasons of infection that include source, susceptible person and transmission. source and susceptible person can be the reason of infection in some non-immune people but the transmission reason can vary. s<em>o, there is probability that three nonimmune people lie under transmission reason and are not coming in contact with infected people, medical equipment or environment, that causes infection and those three people are not getting infected.</em>
<em>Hence, the correct options are 1, 3 and 4.</em>
Answer:
Deltoid
Explanation:
The muscles of the trunk and the muscles of the lower extremity will be used for stability and moving the box across the 2 meters. The muscles of the upper extremity would be used to varying degrees to lift, hold, and lift the box to sternum level and place it in its place and which muscles contribute to the specific portion of the task you intend to study will depend on the magnitude of the load, the frequency the task is completed, the velocity at which the task is completed, the height differential between where the box is lifted from to the height at which the box is placed when the task is completed.
