How would our world be different if humans did not discover how to use yeast thousands of years ago?

Answers

Answer 1

Answer:

what is yeast? a microscopic fungus consisting of single oval cells that reproduce by budding, and are capable of converting sugar into alcohol and carbon dioxide.

Explanation:

ok so it would be different because we wouldnt have alchool and carbon dioxide and sugar would be useless

Answer 2

Answer:

Once upon a time there were no farms. People ate fruit off the vine and killed animals as they ran. They roasted things when it suited them but just as often ate them raw. The world was like this for thousands of years, a place of arrows and nuts where everything that was necessary could be found. One might imagine many reasons for giving up on those old, superficially idyllic, ways. Perhaps it was hunger, that ultimate mother of invention, or maybe it was just invention itself, unmotivated by need.

1.How would you describe the relationship between the eagle and the hare?

2.According to the video, why can't the eagle afford any mistakes?

3.How could an overpopulation of eagles affect the hare population?


1)Describe the relationship between a predator population and the population of its prey.

2)What is a keystone species? Give an example.

3)What is a limiting factor? Give an example.

4)What is the role of camouflage in prey and predator?

Answers

Explanation:

1. Remember, the video began with the words, "For one death, for the other, are all decided in an instance." Meaning, both could result in each other harm. There is

2. The eagle can't afford to make any mistakes because we are told, "even the slightest injury can leave it too weak to hunt and cause it to stave."

3. More eagles means more hares are hunted, and as more hares are been killed, the lesser the hare population.

4. The increase in the predator population leads to a reduction in the population of the prey. In other words, as more predators start looking for prey to eat, the prey population decreases.

5. In simple words, a keystone species is a type of predator whose presence in the community has far-reaching effects on other species in the community. One common example is the sea star species found in coral reefs, see stars feed on mussel and sea urchin thereby helping to regulate the population of mussels and sea urchin. Doing this ultimately helps other species survive.

6. A limiting factor is an attribute or factor that reduces the exponential growth in the population of an organism.

7. Camouflage allows preys to hid from their predators. Usually made possible by their physical appearance.

How are primary and secondary succession similar and how are they different?

Answers

Primary and secondary succession occur after both human and natural events that cause drastic change in the makeup of an area. Primary succession occurs in areas where there is no soil and secondary succession occurs in areas where there is soil.

Answer:

Both human and natural activities that result in a substantial change in the composition of an area create primary and secondary succession. In locations where there is no soil, primary succession takes place, and in areas where there is soil, secondary succession takes place.

Carbohydrates can be used for energy storage or to build structures. Plants store energy as ________A__________ and animals store energy as _______B_________. Plants build structures out of ______C__________.

Answers

Answer:

A. starch

B. glycogen

C. cellulose

Explanation:

Molecules of carbohydrates providing energy and support consist primarily of sugar polymers.  They are formed from monosaccharide monomers in long chains and rings. The basic composition of monosaccharides, disaccharides and polysaccharides comprises the elements C, H O, with several polar groups of OH.

Polysaccharides consist of glucose joined by 1-4 glycosidic bonds. They are used as energy storage in photosynthesis and used by animals in respiration, ethyl alcohol fermentation and lactic acid fermentation for ATP synthesis. Plants transport glucose as sucrose, and store it as starch, while animals store glucose as glycogen.

Glucose is readily converted into another form of chemical energy as ATP. Plants also make up insoluble and stable cellulose and lignin structural units in plants.
