Certain genes that allow for a certain thing to happen are turned on or turned off as needed. A brain cell may have the gene needed to send electrical pulses to other brain cells or other parts of the body, whereas a heart cell may have the genes that allow it to contract to pump blood. (I don't know if those are real genes, but hopefully you get the idea)
Concretions im pretty sure because they are in a <span>spherical shape</span>
Answer:
1. Non-living
2. Reproduce
3. Nucleic acid
4. RNA
5. Protein
6. Capsid
7. Burst
8. Lytic
9. Lysogenic
Explanation:
Viruses are set of organisms classified as NON-LIVING (1) because they do not exhibit the characteristics that living things exhibit. Viruses are incapable of REPRODUCING (2) on their own, and hence, need a living host to infect in order to replicate itself.
In the structural composition of a virus, it is made up of only one type of NUCLEIC ACID (3), which can either be DNA or RNA (4). The nucleic acid is surrounded by a PROTEIN (5) coat called CAPSID (6).
There are two ways a virus can infect its host. First, it can replicate itself causing the host cell to BURST (7) or lyse in a process called LYTIC CYCLE (8). Also, the virus can remain dormant in the host cell and continually replicate with the host cell in a process called LYSOGENIC CYCLE (9).
1. Alloy = Compound
2. Gold = Au
3: Salt Water = Liquid Solution
4. Potassium = K
5. Neutron = No Electric Charge
6. Sugar = Solid Solution
7. Sodium = Na
8. Proton = Positive Electric Charge
<u>I'm sure these are the right answers, but if I got anything wrong, please feel free to state/comment about it. Hope this helps!!</u>
It’s A an generation that’s the only one that makes sense because evolution is a change over time too
