Temperature and salinity
<h3><u>Explanation;</u></h3>
- Differences in the density of water can cause currents to form and move.
- Density is affected by temperature and salinity. Cold water or water with dissolved salts (higher salinity) is denser than warm water or water without dissolved salts.
- The different densities cause the water to move, forming a density current. In the oceans, the deep,bottom currents are colder and saltier than the surface currents.
Answer:
It introduces the body to a virus strand(s) to initiate internal resistance, which is created after a variety of metabolical processes. The idea is that the body would develop immunity to the virus without actually "getting" the virus.
Explanation:
The value of q in p2= 0.49 is A.
0.49(2x0.7xq)+q2=1
1.4qxq2=0.51
1.4qxq=0.714
q+q=0.510
q=0.26
round it up to 3
