In the scientific method, a(n) ______ is an investigation carried out under controlled conditions to test a hypothesis.

Hello. You have not submitted the experiments to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.

A dependent variable is one that is influenced by an element, in order to present a result, that is, it is a variable that does not establish itself, being dependent on another variable to establish itself. An example of a dependent variable can be seen in an experiment that seeks to determine the differences in growth rates of bean plants that were fertilized with different organic fertilizers. As you can see, this is an experiment where the different organic fertilizers influence differences in the growth rate of bean plants. Thus, the growth of these plants depends on the fertilizer, this growth being the variable dependent on the experiment.

A control group, in turn, is an element of the experiment that does not receive the element that is being tested in the same experiment. The control group is important, because it allows the researcher to see the results of a system where the tested element does not exist, thus being able to determine the real differences that the tested element is capable of causing. Using the same example presented in the paragraph above, we can see that the different organic fertilizers are the elements tested in the experiment. These fertilizers will be applied to the plants, however it is important that at least one of these plants does not receive any fertilizer, so that the difference between a system with fertilizer and a system without fertilizer can be evaluated. This plant that received no fertilizer is the control group.

You're correct.

Impermeable and/or non-porous materials include clay, non-fractured igneous and metamorphic rocks. Porous/permeable layers are called aquifers; impermeable layers called aquiludes.

Option A: In terms of making biofuel, the farm crop that would typically result in the largest amount of oil produced per acre of crop is Algae.

Algae are known for their high oil content, which can be extracted and converted into biofuel. Algae have a fast growth rate and high oil productivity, making them an attractive option for biofuel production. They can be grown in large quantities in relatively small areas, such as ponds or bioreactors, maximizing the oil yield per acre.

However, compared to algae, the oil content and yield per acre in other crops mentioned here are generally lower. Corn and soybeans are typically cultivated for their primary agricultural uses, such as food crops or animal feed, rather than as dedicated oil crops.

Answer:

The word for the blank spot is Recessive.

Explanation:

Food chains, webs, and energy pyramids are all methods used to represent the flow of energy and nutrients in an ecosystem. A food chain is a simple linear representation of the transfer of energy from one organism to another. It typically starts with a primary producer and ends with a top predator.

A food web, on the other hand, is a more complex representation of interconnected food chains. It shows the feeding relationships among many different species in an ecosystem.

Finally, an energy pyramid represents the amount of energy that flows through each level of a food chain or web. It is typically shaped like a pyramid because the amount of energy decreases as you move up the trophic levels.

Overall, food chains are simple and straightforward, while food webs and energy pyramids are more complex and show the interconnectivity of species and energy flow in an ecosystem.

Fermentation

Explanation:

Hope this helps!

The production of alcohol by yeast cells is the result of anaerobic respiration. The correct option is D).

All living cells undergo respiration, a chemical activity that releases energy from glucose. Without oxygen, anaerobic respiration occurs and produces less energy but does it more quickly. Fermentation refers to anaerobic respiration in microorganisms.

When you work out vigorously, your muscles engage in anaerobic respiration. Compared to aerobic respiration, less energy is released because glucose is not completely broken down.

During intense activity, lactic acid accumulates in the muscles. Later, the lactic acid must be oxidized to produce carbon dioxide and water.

Therefore, the correct option is D) Anaerobic respiration.

Answer:

from areas of high pressure to areas of low pressure

Explanation:

Air flows from areas of high pressure to areas of low pressure due to pressure differences.

Air molecules naturally move from an area of higher pressure to an area of lower pressure in an attempt to equalize the pressure.

This movement of air creates wind or air currents.

The air moves in the direction where the pressure gradient is steepest, which is typically from areas of high pressure to areas of low pressure.

This movement is known as the flow of air from high pressure to low pressure.

Hope this helps!

Answer:

from areas of high pressure to areas of low pressure

Explanation:

The moving force of air flows from areas of high pressure to areas of low pressure. Air moves from high-pressure zones to low-pressure zones because of the difference in air pressure. This movement of air from high to low pressure is what creates wind. The greater the difference in pressure between two areas, the stronger the wind will be. So, the correct answer is "from areas of high pressure to areas of low pressure".

Explanation:

has a sizable percentage of its npp devoted to secondary chemicals. This is due to the possibility of secondary chemicals, such as poisons and other chemical defences, aiding in the plant's herbivore defence.

The warm, swampy atmosphere may also encourage the development of bigger plants with more powerful roots that can help them anchor themselves and take up nutrients from the nutrient-rich soil. The plant can thrive under these circumstances by allocating a large part of NPP to the roots. Life on Earth depends on a wide variety of creatures called plants. Through the process of photosynthesis, they are primary producers that turn light, water, and carbon dioxide into energy. The development and reproduction of the plant are then fueled by this energy.

False. The given statement is not true. The given statement presents a contradiction in units. The diameter of an arteriole is provided in millimeters (mm), while the rate of blood flow is given in cubic centimeters per second (cm^3/s).

This discrepancy in units makes it impossible to determine the blood speed in the arteriole based on the information provided. To calculate blood speed, one would need to know the cross-sectional area of the arteriole in addition to the flow rate. With the given information, it is not possible to accurately determine the blood speed. It's important to note that the diameter of an arteriole can vary depending on the specific vessel and the physiological conditions. Arterioles are small branches of arteries that regulate blood flow and play a role in controlling blood pressure. The blood speed in arterioles is typically slower compared to larger arteries as arterioles have a smaller diameter and higher resistance to blood flow.

True. The motor division of the somatic nervous system provides both excitatory and inhibitory signals to skeletal muscles. The somatic nervous system controls voluntary movements and is composed of two parts: the sensory division and the motor division. The motor division is responsible for carrying motor signals from the brain and spinal cord to the skeletal muscles. It provides both excitatory and inhibitory signals to the skeletal muscles, which helps to coordinate and control movements. Excitatory signals activate the muscles, causing them to contract, while inhibitory signals prevent the muscles from contracting. Both types of signals are important for proper muscle control and movement. In summary, the motor division of the somatic nervous system provides both excitatory and inhibitory signals to skeletal muscles.

Explanation:

Source is where the carbon dioxide is been produce from while the sinks are the various portion that utilizes the carbon dioxide.

If the source releases more of carbon dioxide into the atmosphere than the sink takes up then excess of carbon dioxide will be found in the atmosphere which is not good for the earth as it leads to global warming together with other green house gases.

When the sinks takes up more, then carbon dioxide will be insufficient to the sources with some source having it and others not having at all. Carbon dioxide is of high importance to plant as its a major source of food production through photosynthesis this will be greatly affected.
