Give three reasons why you might have a situation in which bacterial colonies were found on the first section of a streak plate,

but not on sections two and three.

Hi. You have not shown the sections this question refers to, nor have you provided more information about those sections. This makes it difficult for your question to be answered. However, I will try to help you as best I can.

Generally speaking, we can consider that there was no growth of bacterial colonies in sections 2 and 3, because, for some reason, the bacteria was not inoculated in sections 2 and 3. What could also have happened, is that the bacteria in the sections 2 and 3 were eliminated, but the bacteria from section 1 managed to survive and form colonies.

Another possibility is that after inoculating the bacteria in section 1, you didn't handle the bacteria correctly in the other sections, leaving that bacteria to dry out and die.

Finally, the culture media in sections 2 and 3 could be inappropriate for bacteria to develop and form colonies.

The Spanish Civil War is also known as The Crusade (Spanish: La Cruzada)

Soviet Union and Mexico supported the Cold War.

Countries like the Soviet Union and Mexico supported the Allies,

while countries like Germany and Italy supported Nazism.

<h3>Who were the Allies of the Nazis?</h3>

The Axis countries (Germany, Italy and Japan) and the Allies (France, England, USA and, later, USSR) constituted the alliances formed in the Second War. World War II was a conflict of global proportions that took place between 1939 and 1945.

With this information, we can conclude that the Spanish Civil War resulted from a confrontation between fascist and communist nationalist forces, which began to vie for power in the country.

Well, wind and solar energy are good places to look at. The highest wind speed recorded in Antartica was roughly 199 mph, so they would definitely gain a large amount of energy from the wind. A smaller turbine can handle severe weather conditions, so setting some up along the most wind ridden places would be good. Solar energy would also be the best option since their days are longer than their nights over there. There can be days at a time where the sun doesn't rise at all, and then there are some where there is sunlight for a full 24 hours. So, it really depends on your preference, and the cons and pros of the energy type.
For wind: Set up a series of turbines along the areas that have the most wind. Turbines can withstand large storms. There is usually some kind of wind blowing.
For solar: Set up some solar panels where they would be able to get the most amount of sunlight. There are 24 hour long days of sunlight, but there are also some days where there is no sunlight at all.

Hope this helps you a bit.

Which of the following is a major determinant of the distribution pattern of a population?
horrorfan [7]

Answer:

a.) rate of population growth

Explanation:

The population growth rate determines how a population will be distributed in a region. Populations with a high growth rate need to occupy more spaces, in addition to needing to consume a greater volume of natural resources. As the population grows, the distribution in the region becomes more intense, the opposite also happens. When the population growth rate indicates that the population is decreasing it means that this population will need less space and therefore, its geographic distribution will be smaller, as well as its impact on the region.
