<u>Answer</u>:

Rich countries can be described as having consumerist society in which the increasing acquisition of goods and services is encouraged. Thus, from a society such as this, the waste produced is also extremely large. So large that in many cases the system that should handle it is not capable of doing so.

Furthermore, the people themselves do not dispose of this waste in a responsible manner. Instead, parts of it are just through into nature where it eventually ends up in aquatic and especially marine environments.

By reducing the amount of used goods or at least the amount of packaging, will be a first step in reducing this environmental danger. However, more is necessary.

The consumerist mindset is not sustainable. Instead of throwing away a product such as a plastic cup, it could be reused several times. This would also lead to a waste reduction.

Perhaps the best solution is to recycle if not all, then most of the waste produced. By recycling, the waste itself will be eliminated to a large degree. Also, the amount used will not be such a big problem anymore as the used products are recycled into new ones.

Recycling will benefit greatly the marine environments by ceasing further pollution. The waste already present could be gathered and turned once more into a useful product.

Unfortunately, this solution is also the most expensive as extensive financial resources are necessary for the creation of the infrastructure of a recycling waste management system. However, long-term this investment will show itself to be profitable as, after all, our health is dependent on Earth's health.

Ou just read an article on the Endosymbiotic Theory. Based on what you read, what is the importance of the Endosymbiotic Theory?

VikaD [51]

Answer: The endosymbiotic theory suggests that eukaryotic organisms evolve from primitive prokaryotic organisms.

Explanation:

According to the endosymbiotic theory the organelles like mitochondria and chloroplast in the eukaryotic cells have arisen from aerobic bacteria. The aerobic bacteria being prokaryotic cell was consumed by the anaerobic bacteria or prokaryotic cell.

The following are the evidences of the origin of eukaryotic organisms from prokaryotic organisms:

1. The chloroplast and mitochondria have circular DNA like bacteria.

2. The mitochondria and chloroplast reproduce through binary fission which also occurs in bacteria.

Life as we know it depends on the genetic code: a set of codons, each made up of three bases in a DNA sequence and corresponding

slava [35]

Answer:

In the most general case of x bases and y bases per codon, the total number of possible codons is equal to xy . In the case of the hypothetical Martian life-forms, is the minimum codon length needed to specify 17 amino acids is 5 (25 = 32), with some redundancy (meaning that more than one codon could code for the same amino acid). For life on Earth, x = 4 and y = 3; thus the number of codons is 43, or 64. Because there are only 20 amino acids, there is a lot of redundancy in the code (there are several codons for each amino acid).

yulyashka [42]

number 8 is b because when you eat plants or animals, it get transfred to glucose which is then transfered to atp. Think about it this way, when you are sick, you dont just go outside in the sun to recharge and then you suddenly get better, and energy, you have to rest and eat certain foods that will restore your ATP levles.

5. What is the difference between mitochondria and chloroplast?

FinnZ [79.3K]

Answer:

C. Mitochondria convert sugars into energy, while chloroplasts carry out

photosynthesis.

Explanation:

Chloroplasts have the ability to use light to convert carbon, derived from carbon dioxide into sugar. Mitochondria on their part break down simple sugars into carbon dioxide and release energy. Chloroplasts are larger and have greater complexity than mitochondria, and they have several critical functions to perform, besides the generation of ATP. Apart from converting carbon dioxide to carbohydrates they synthesize amino acids, fatty acids, and the lipid contained in their own membranes.

Mitochondria are to be found in both plant and animal cells, whereas chloroplasts are found only in plant cells. The former have a structure composed of a prokaryotic cell, whereas Chlorplasts are made up of stacks of thylakoids surrounded by a fluid called stroma. According to some theories, mitochondria exist because of endocytosis of aerobic bacteria, while chloroplasts are around because of the result of endocytosis of photosynthetic bacteria.

Chloroplasts exist only in plant cells and lend the green color of most plants. Mitochondria on the other hand are found in both animal and plant cells and are engaged in the production of ATP. To use simple layman language, mitochondria in animal cells changes energy into forms that animals can use, while chloroplasts in plant cells convert sunlight into energy that plants can use. From this it follows that mitochondria in a sense are the power plant in the animal cells, because it generates energy. Chloroplasts provide the green color to the plant due to the chlorophyll present in them.

Mitochondria cells are 1 to 10 um long in length. These can change shapes, get around, and divide into two. The cell is surrounded by an envelope of two membranes. The membrane on the outside is smooth while the other one is marked by what are called cristae.

Photosynthesis happens only in plants. This is because only plants contain chloroplasts. Thus we can see that mitochondria and chloroplasts are the building blocks of life for plants and animals respectively in the sense that they provide nourishment to the organisms. The two are also representative of the dividing line between the two kingdoms of life on earth-the animal and the plant.

These two structures are markers of two philosophies of life form if one may use the use the term. One that is self sustaining, manufacturing its own food, the other that is dependent upon the former as the primary source of food, but far more complex and evolved way of life in many other aspects.
