A student decides to set up an experiment to see if detergent affects the growth of seeds. He sets up 10 seed pots. 5 of the see

Trava [24]

Answer:

The correct answer is option C) "More than one variable is being tested".

Explanation:

One of the basis of scientific experimentation is to test one variable at the time in order to make sure that the response that is being obtained is the result of that variable and not another one that is not taking into account. In this case, the student is making the mistake of assessing two variables at the same time: the use of detergent and placing the plant in the sun or in the shade. At the end of the experiment the student will not know if the response is the effect of the detergent, the exposure to the sun or a combination of both.

Someone help me with this one please

astraxan [27]

Producers are organisms that capture sunlight from the sun to make organic food. Consumers are animals and get food by consuming other organisms. Decomposers break down all dead organisms from a soil bacterium part of the food cycle. Detritivore feed on organic matter. Producers get their food from the sun. And compete with all organisms above them on the food pyramid. A food chain is a cycle pathway of life, relationships among organisms is a mutualism that results in energy. Most energy is lost as metabolic heat, the total heat, and energy wast. Meaning that each level only receives 10% of the energy in the level

Hope this helps if I am wrong please let me know :)

In a population of beetles, there are green and brown colorations that occur with equal frequency. After a forest fire, only 20

Artemon [7]

Answer:

A population bottleneck occurred, altering the resulting allele frequencies.

Explanation:

A population bottleneck occurs when the size of a population is reduced by at least a generation. In this case, genetic drift acts more quickly to reduce genetic variation in small populations, but going through a “bottleneck” can greatly reduce variation, even if the bottleneck does not last for many generations. This effect called a bottleneck usually happens when a major disaster occurs in the population's habitat, changing the allelic frequencies and even the genetic variability of the population.

The population bottleneck can be seen in the question above, where after a forest fire, only 20 beetles remain in a population of beetles. 18 of them are green and 2 of them are brown.

Please sort each of the following statements as being either an external or internal factor that affects the growth of microorga

alexandr402 [8]

Answer:

External factors can be described as factors which give rise to a situation from outside. Internal factors bring a change or give rise to a situation from internal conditions.

External Factors:

Temperature of food storage during processing.

Humidity of the storage environment

Presence of gases, such as CO2, during packaging

Preservatives, such as salt and sugar

Handling of food by manufacturers

Internal Factors:

pH of the food

Presence of antimicrobial compounds

Nutrient content (Such as vitamins and minerals)

Moisture content or water activity

Protective structure of food, such as feathers, hide and skin
