The experiment to help Lillian's parents will consist of planting various carrots using both kinds of fertilizers, and maintaining a constant carrot type, amount of light, and amount of water throughout each plant.

In order to perform an accurate experiment, we need to identify three kinds of variables:

In an experiment, the Independent variable is one whose value does not depend on the others. What this means is that this variable will not react to changes that occur in others. In this experiment, the independent variable is the fertilizer, given that it is not affected by the species of carrot, type of soil, or any other variable present.

The dependent variable in an experiment is just the opposite, it is, as the name implies, a variable whose value depends on the other variables present. In an experiment, this variable represents the data that we seek to measure. For this experiment, the dependent variable is the growth rate of the carrots because it is affected by the amount of water, light, and type of fertilizer we use, as well as being what we wish to measure.

Finally, the last variable we must identify is that of the control variable, also known as the constant or standardized variable. This variable is of vital importance for the accuracy of any experiment. This variable corresponds to those factors which we maintain constant through each trial in the experiment, for the example above, it is the amount of water and light, as well as the type of carrot, Lillian's parents will use.

Triggering of the muscle action potential occurs after Ach binds to chemically gated channels in the motor end plate membrane. Acetylcholine (Ach) is a neurotransmitter produced by nerve cells.

An action potential is an electrical signal that travels along the cell membrane as a wave.

This action potential (muscle action potential) drives the contraction of muscle fibers.

When the action potential reaches the neuromuscular junction (i.e., the motor end-plate), acetylcholine (Ach) is released into the synaptic cleft.

Subsequently, Ach can bind and open specific channels localized on the surface of the muscle cells, thereby depolarizing them and triggering muscle contraction.

Answer:

Explanation:

Photosynthesis requires energy to build organic molecules.

Remove brackets before and after requires and comma in the sentence, it will be correctly punctuated as above.

Answer:

Explanation:

photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

A climate zone is a world area or region distinguished from a neighbor by a major physical climatic characteristic that is of global scale.

Answer:

The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources). Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.

Answer:

The gas inhibits the escape of heat from Earth’s

Explanation:

This is the main cause of global warming. They cause climate change by trapping heat and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.

The earth temperature depends upon the balance between the incoming radiation from the sunlight and the energy that is reflected back to space. Carbon dioxide absorbs the heat sent to earth by the sun, it acts as an insulator of the earth and helps to keep the atmosphere warm and make suitable for life process.

But, when the concentration of carbon dioxide in the atmosphere is increased, it means more and more increase in the temperature of the planet and cause global warming and make the life difficult on the planet. As a result of that whole life on the earth would be in danger.

Answer:

If you increase carbon dioxide, the temperature can go up causing our earth to have global warming problems.

Difference threshold refers to the just-noticeable difference between two stimuli (Option D). This difference represents the minimum level of stimulation that can be detected by an individual at least half the time.

An absolute threshold can be defined as the lowest level of a stimulus which can be detected by a person at least half the time.

In psychology, an absolute threshold is defined as the minimal amount of energy required to achieve the stimulation of the sensory receptors.

Stimuli from the surrounding environment include touch, light, sound, etc.

Answer:

Most life on Earth depends on photosynthesis.The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.
