How does the greenhouse effect affect climate change
exis [7]

Earth's temperature depends on the balance between energy entering and leaving the planet’s system. When incoming energy from the sun is absorbed by the Earth system, Earth warms. When the sun’s energy is reflected back into space, Earth avoids warming. When absorbed energy is released back into space, Earth cools. Many factors, both natural and human, can cause changes in Earth’s energy balance, including:

<span><span>Variations in the sun's energy reaching Earth</span><span>Changes in the reflectivity of Earth’s atmosphere and surface</span><span>Changes in the greenhouse effect, which affects the amount of heat retained by Earth’s atmosphere</span></span>

These factors have caused Earth’s climate to change many times.

Scientists have pieced together a record of Earth’s climate, dating back hundreds of thousands of years (and, in some cases, millions or hundreds of millions of years), by analyzing a number of indirect measures of climate such as ice cores, tree rings, glacier lengths, pollen remains, and ocean sediments, and by studying changes in Earth’s orbit around the sun.

This record shows that the climate system varies naturally over a wide range of time scales. In general, climate changes prior to the Industrial Revolution in the 1700's can be explained by natural causes, such as changes in solar energy, volcanic eruptions, and natural changes in greenhouse gas (GHG) concentrations.

Recent climate changes, however, cannot be explained by natural causes alone. Research indicates that natural causes do not explain most observed warming, especially warming since the mid-20thcentury. Rather, it is extremely likely that human activities have been the dominant cause of that warming. Hope i was helpful.

Shortly after the zygote is formed, it begins the processes of duplication and division. Each resulting new cell has:
seropon [69]

Answer:A. the same number of chromosomes as was contained in the zygote.

Explanation:a zygote is formed when the sperm fertilize the egg .

After fertilization,the zygote undergoes cleavage.cleavage is the mitotic Division of the cells of a zygote to produce daughter cells.

These daughter cells are called blastomere,which contains the same number of chromosomes as the parent cells.the cells formed do not grow in size but continues to divide, forming a mass of cells.

This mass may be solid at first but as cleavage continues,the cells move away from the center,leaving a fluid filled cavity in the middle (blastocoel).

The mass of cells are called blastula.

Blood pressure machine is already a technology now, so that one is wrong. 

Well, actually, in-home robots would not be able to help with healthcare as much. 

And electronic asprin I don't see how that would help.

So, I think the answer would be the b. Virtual doctor appointments.
