The first option for 1 and the second option for 2
A) .was immediately accepted
Explanation:
The theory of plate tectonics was immediately recognized as the explanation for the moving continents. It provided a more scientific background as why continents drift apart and the seafloor keeps spreading.
- The theory explains that the earth is broken up into series of slabs called lithosphere which moves on the weak, ductile and fluid asthenosphere.
- The movement of part of the earth mantle provided the mechanism through which the lithosphere moves. This is now known as the mantle convection.
- This theory provided a scientific mechanism through which the plate moves and seafloor spreads.
- It was immediately accepted when the theory was propounded by Alfred Holmes in the 1930s

B. Ice-albedo feedback
Explanation:
The ice-albedo feedback is one process that can significantly increase the rate of greenhouse emissions in response to a decreased albedo.
Albedo is the ratio of reflected light to incident light.
A decrease in albedo suggests that a surface is absorbing more light than it is reflecting. This is typical of areas with land cover and vegetation.
Areas with a high reflectivity have a high albedo. Snow, ice and polar regions are good reflectors of solar radiation. They have a very high albedo close to 100%. Much of the surface area is buried with ice.
Examples of greenhouse gases are carbon dioxide, methane, water vapor e.t.c
How does a low albedo relates to increase in greenhouse gas emission?
- The ice-albedo feedback can substantially contribute to greenhouse gas emission.
- The high reflectivity of ice causes long wave radiation to warm the air around a icy body in polar regions.
- When ice melts, they leave land bare and exposed.
- Melt water collects in pockets.
- Exposed land leads to a decrease in albedo.
- Organisms can thrive more in warm terrain.
- Also, pockets of carbon dioxide gases trapped in ice is released.
- Organisms release carbon dioxide into the atmosphere during cellular respiration.
- Soils originally permafrost will become stable and this will encourage more human occupation of the area.
- All these activities leads to an increase in the emission of greenhouse gases in an area with low albedo.

Adenine (A) binds with Thymine (T).
<span>Guanine (G) binds with Cytosine (C).
</span>
Adenine and Guanine are purines. Thymine and Cytosine are pyrimidines.
Hope this helps !

Answer:
Antibiotics cannot kill viruses because bacteria and viruses have different methods to survive and replicate. Viruses replicate via inserting their DNA into a host cell.
