inject DNA or RNA into the nucleus of a cell to reproduce.
Answer:
The characteristic of injecting DNA or RNA into the nucleus of a (host) cell corresponds to viruses.
Explanation:
Viruses are not considered living beings, since they are only made up of genetic material covered by a viral capsid and cannot fulfill the functions of a cell. For this reason viruses need to introduce their genetic material into a host cell, to transcribe its genetic code and achieve replication.
Due to their mechanism of reproduction, viruses are biological agents capable of producing disease by altering the conditions of the organisms they use as hosts.

2. Given a force of 100 N and an acceleration of 10 m/s, what is the mass?
Given:
Show your work:
F = 280n
a=0.5 m/s2
m=i
Explanation:
This question is a bit unclear. I think it's two questions conjoined. Anyways,
F=m×a
F=100N
a=10m/s^2
m=?
Making m the subject of formula
m=F/a
Substituting we have,
m= 100/10
m=10kg
Using the formula for m above
F=280N
a= 0.5m/s^2
m=?
m=280/0.5
m=560kg
Let's check our answers
F=m×a
F=10kg×10m/s^2
F=100N
Correct✓
F=560kg ×0.5m/s^2
F=280N
Correct✓
I hope this is timely;-)
