Answer:
c. The current changes are happening much faster than past changes.
Explanation:
This is correct because the earth's atmosphere is warming at an exceedingly high rate. This is due to the rise in amounts of carbon dioxide in the atmosphere among other factors. If the current trends were a representation of Earth's natural climate cycle then they would not be as high as they are now.

Do you think that our society should try to genetically “engineer” babies? Do you think that one day we will? Explain your answers.
Im giving out brainliest!
Answer:
I think they should not genetically engineer babies because it is inhumane, they might as well make robots and forget about humans. Sadly I think one day we will, if they are able to implant a baby in a woman, they will soon be able to make a baby without a womb.
Answer:
I don't think we should "engineer" babies, they have their own life and changing that to make another that God did not make will turn out weird. God creates the babies, only he can make them perfect. But sadly, yes, I think people will try to "engineer" babies.

How are the products and reactants of photosynthesis and cellular respiration related?
The formation of food by trapping the sunlight is called photosynthesis. The digestion of the food to get the energy in the presence of oxygen is called respiration.
These two processes are interrelated with each other because the product of photosynthesis is glucose which is made up of carbon dioxide and oxygen.
In respiration, the cell uses the molecule which is made in the process of photosynthesis that is glucose. It breakdown into its monomer and give the energy.
Hence, In this way, these reactions are inter- related.

Which coast of north America has the greater amount of earthquakes, volcanoes and mountain s?
Answer:
There are more earthquakes on the West coast of the United States, because the boundaries of the North American, Pacific, and Juan de Fuca tectonic plates are located there. As the edges of the plates slide past or are forced under each other, the movement creates earthquakes

Explain why insect farming is more sustainable than raising large livestock, such as cattle or chickens. Do you think more Americans will embrace the idea of eating insects? Why or why not?
Answer:
The major environmental advantages of insect farming compared to livestock production are as follows: (1) less land and water is required; (2) greenhouse gas emissions are lower; (3) insects have high feed conversion efficiencies; (4) insects can transform low-value organic by-products into high-quality food or feed.
Insects release fewer greenhouse gases than traditional livestock. Rearing traditional livestock accounts for 18% of greenhouse gas emissions (pdf, p . 63), which trumps emissions by the transportation industry. ... Insects also release much less ammonia and methane than pigs and cattle.

Kawana knows that the sandwich she eats for lunch will give her energy for lacrosse practice that afternoon, but she wonders exactly how the food will reach her cells and enable her muscles to move. Give a brief description of how energy from food is made available for cellular use.
Answer:
In my own point of view, energy from food can be made available for cellular use because the food (the sandwich) she eats for lunch contains balanced diet. In which she eats through the mouth, swallows the food which goes down the oesophagus and it reaches the stomach and digestion processes starts. The digested food is stored in the body and is thereafter made available for cellular use
