Explanation:
Bacteria have existed from very early in the history of life on Earth. Bacteria fossils discovered in rocks date from at least the Devonian Period (419.2 million to 358.9 million years ago), and there are convincing arguments that bacteria have been present since early Precambrian time, about 3.5 billion years ago. Bacteria were widespread on Earth at least since the latter part of the Paleoproterozoic, roughly 1.8 billion years ago, when oxygen appeared in the atmosphere as a result of the action of the cyanobacteria. Bacteria have thus had plenty of time to adapt to their environments and to have given rise to numerous descendant forms.
The nature of the original predecessor involved in the origin of life is subject to considerable speculation. It has been suggested that the original cell might have used RNA as its genetic material, since investigations have shown that RNA molecules can have numerous catalytic functions. The Bacteria and Archaea diverged from their common precursor very early in this time period. The two types of prokaryotes tend to inhabit different types of environments and give rise to new species at different rates. Many Archaea prefer high-temperature niches. One major branch of the archaeal tree consists only of thermophilic species, and many of the methanogens in another major branch can grow at high temperatures. In contrast, no major eubacterial branch consists solely of thermophiles. Both Bacteria and Archaea contain members that are able to grow at very high temperatures, as well as other species that are able to grow at low temperatures. Another prominent difference is that bacteria have widely adapted to aerobic conditions, whereas many archaea are obligate anaerobes. No archaea are obligately photosynthetic. Perhaps the archaea are a more primitive type of organism with an impaired genetic response to changing environmental conditions. A limited ability to adapt to new situations could restrict the archaea to harsh environments, where there is less competition from other life-forms.
What is China’s major land problem?
Podemos dizer que as populacoes de nossa senhora do socorro e aracaju apresentam esse movimento pendular?
é possivel afirmar que Aracaju e Nossa senhora do socorro apresentam movimentação pendular, se existe uma movimentação de pessoas para fora dessas cidades, para fugir da violencia, ou de outra caracteristica negativa que essas cidades apresentam.
Isso ocorre porque o movimento pendular é o termo que se refere a descentralização, ou seja a saída de pessoas de grande centros urbanos para regiões no ionterior. Isso ocorre porque as pessoas estão fugindo de caracteristicas negativas dos centros urbanos como violenica, poluição, transito, alto preço imobiliario, dentre outros.
Obs: Perguntas em pertugues devem ser postadas no campo "world languages" porque esse não é o servidor brasileiro e sim o servidor americano.

Submit your project identifying potential customers. Be sure to follow these guidelines:Identify the type of products your new company sells.
Describe the target market for your products.
List at least 10 potential customers in your target market.
Explain why these customers would be interested in your company’s products.
Write your response in complete sentences and paragraphs.
Explanation:
target market, or target audience, is the pool of customers to whom you want to potentially sell your products or services. Your target market is not everyone who is located in your business’s area. It’s only made up of the people who are good fits for your products. Basically, you want to figure out which fish in the ocean you’re going to focus on catching.

Explanation:
How many square inches will it take to cover the outside of the triangular pyramid below? 12 in 10.4 in and 12 in
Answer:
249.6 sq. in.
Explanation:
In this question, we need to find the surface area of the triangular pyramid in order to calculate how many square inches are needed to cover it. The formula for the surface area of a triangular pyramid is the following
[tex]\frac{1}{2}[/tex](a × b) + [tex]\frac{3}{2}[/tex](b × s)
We can say that the values provided represent the following variables.
a = 12in
b = 10.4in
s = 12in
[tex]\frac{1}{2}[/tex](12 × 10.4) + [tex]\frac{3}{2}[/tex](10.4 × 12)
[tex]\frac{1}{2}[/tex](124.8) + [tex]\frac{3}{2}[/tex](124.8)
62.4 + 187.2
249.6 sq. in.
Finally, we can say that it would take 249.6 sq. in. in order to cover the triangular pyramid.

Which of the following strategies would best help a city combat a growing urban heat island?
A.
raise the electricity usage in city buildings
B.
eliminate native species growing in a city
C.
improve police resources to fight crime better
D.
combat the overuse of asphalt and concrete surfaces
Please select the best answer from the choices provided.
Answer:
D). Combat the overuse of asphalt and concrete surfaces.
Explanation:
Urban Heat is characterized as the circumstance in which a particular urban area has a considerably increased temperature because of specific human activities. As per the question, the most adequate strategy to assist a city in fighting the battle against the increasing 'urban heat island' would be to 'avoid the excessive use of surfaces made of concrete and asphalt.' The key reason behind this is that 'asphalt and concrete surfaces tend to possess an extremely higher heating capacity' and thus, it absorbs heat from the sun and causing the land temperatures to reach higher till 60° celsius. Therefore, preventing the overuses of such surfaces would be the most adequate strategy to keep the temperatures in control. Hence, option D is the correct answer.

China’s growth over the past 20+ years has been rapid. why?
Answer:
Economists generally attribute much of China's rapid economic growth to two main factors: large-scale capital investment (financed by large domestic savings and foreign investment) and rapid productivity growth. These two factors appear to have gone together hand in hand.
It appears that religion has been around in one form or another for most of human history. Do you think it is getting stronger, dying out, or staying about at the same level of importance? Why?
I think this question is very dependent on who you ask personally I dont think its dying out but I definitely think it's less of a key aspect of society then it ever was. I think this because being apart of the the younger generation we have been taught to question everything, and religion doesn't always have the answers nor does it line up with alot of morals that people have.
i don't know this is just my opinion I hope it helps!!

Give one effect of deforestation on the soils of the rainforest
Answer:
soil erosion and coastal flooding.
Explanation:
Erosion generally decreases the productivity of forests by decreasing the available soil water for forest growth and through loss of nutrients in eroded sediment.
Soil erosion can go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species.
Identifiquen que montañas corresponden las siguientes coordenadas: LATITUD LONGITUD MONTAÑA 28ºN 86ºE 32ºS 70ºO
Answer:
1) Las montañas ubicadas en las coordenadas 28º N 86º E son las de la cordillera del Himalaya, dado que dichas coordenadas se corresponden con la región de Nyalam, en el Tíbet, dentro de la República Popular China y muy cerca de la frontera con Nepal. Es una zona de elevada altitud (se ubica a casi 4,000 metros sobre el nivel del mar), en plena cordillera de los Himalayas.
2) Las montañas ubicadas en las coordenadas 32ºS 70ºO son las de la cordillera de los Andes en América del Sur, dado que las coordenadas brindadas pertenecen a Calingasta, en la Provincia de San Juan, Argentina, región cuyo pico máximo de altitud supera los 6,000 metros sobre el nivel del mar.
