Answer:

1. succession

2. exponential growth

Explanation:

1. Ecological succession is how biological communities change, re-structure and re-assemble over time, usually after some change or disturbance, or occupation of a new habitat. Ecological succession usually starts with a very simplistic structure, with some founder species that begin, then over time (it could be 10 years, it could be millions of years), the population grows in complexity and develops.

2. Exponential growth refers to a specific pattern of growth that occurs when resources are not limited. This pattern is when the size of the population is always increasing at a greater and greater rate. The best example is in bacteria. When they are in favourable conditions, the cells keep dividing, doubling every day, leading to exponential growth until nutrients become limited and growth slows.

In the early twentieth century, what was Alexander Fleming’s hypothesis concerning the relationship between a yellow-green mold
SpyIntel [72]

Answer:

The correct answer is the option c)He thought the mold had released a chemical that prevented the bacteria’s growth.

Explanation:

In the 1920s, Alexander Fleming was working in his laboratory at St. Mary's Hospital in London when, almost by accident, he discovered a naturally growing substance that could attack certain bacteria. In one of his experiments, Fleming observed that colonies of a bacterium had been depleted or removed by a mold that grew on the same Petri dish. He observed that the bacteria furthest from the fungus had grown to produce large-sized colonies, while the colonies closest to the fungus were tiny. He determined that mold made a substance that could dissolve bacteria. The fungus was penicilium chrysogenum and thus Fleming called this substance penicillin, by the name of the mold that produces it. Thus, after several years of experiments in 1930, Howard Florey and Ernest Chain developed at Oxford University the procedures to produce pure penicillin from the fungus that Fleming isolated. Thus penicillin could be concentrated by Florey and Chain, and in 1945 they shared with Fleming the Nobel Prize in Medicine.

Then, <u><em>the correct answer is the option c)He thought the mold had released a chemical that prevented the bacteria’s growth.</em></u>

Qual a relação e as PROPORÇÕES entre Joules, cal, Cal, e Kcal?
RUDIKE [14]

Answer:

Check Explanation

Verificar explicação

Explanation:

English Translation

What is the relationship and the PROPORTIONS between Joules, lime, Cal, and Kcal?

Joules is the SI unit of Energy (heat energy).

Calorie, also called lime, is the amount of heat required to raise the temperature of 1 gram of pure water by 1°C or 1 K.

1 calorie = 4.186 J

A thousand calorie is equal to 1 kcal.

Hence,

1 kcal = 1000 calories = 4186 J

In Portugese/Em português

Joules é a unidade SI de energia (energia térmica).

Caloria, também chamada de cal, é a quantidade de calor necessária para elevar a temperatura de 1 grama de água pura em 1°C ou 1 K.

1 caloria = 4,186 J

Mil calorias é igual a 1 kcal.

Portanto,

1 kcal = 1000 calorias = 4186 J

Hope this Helps!!!
