Fill out the data table below with the range of each factor that will produce the optimal number of oxygen bubbles.

Answers

The optimal ranges for the formation of oxygen bubbles vary between each plant, however, only water, c02, and temperature are limiting factors for photosynthesis.

This question is based on observations made during the course of an experiment designed to measure the optimal ranges at which oxygen bubbles form, given that these are an indication of photosynthesis.

Due to this, the information given will be generalized. Firstly, there is no exact optimal range of light for the formation of oxygen bubbles (photosynthesis) given that this is not a limiting factor.

Excess of light will have no effect on photosynthesis, only the lack of light can cause negative effects, therefore any light past the minimum threshold is fine.

On the other hand, water, light, and C02 are in fact limiting factors and have optimal ranges. For water, this optimal range varies greatly and therefore I cannot offer a general value, but an excess of water will "drown" plants by not allowing the formation of air pockets in the soil.

C02 sits at an optimal range of 1,000-1,300ppm for the best results. Lower concentrations cause a lower rate of photosynthesis given that it is the primary substrate for the process to begin. At too high levels, plants will have to adapt which can slow the process.

Finally, temperature is also a limiting factor for photosynthesis. Its exact value cannot be given since it varies greatly between plant species.

However, in general, terms, since it is an enzyme-dependent reaction, we can apply the general temperature at which enzymes function best which is around 37 degrees.

place each of the labels in the proper position to denote whether they would pass through the filtration membrane or not.

Answers

The labels that will pass through the filtration membrane are water, glucose, and sodium.

The labels that will not pass through the filtration membrane are red blood cells, lymphocytes, antibodies, and platelets.

The filtration membrane is a microporous glomerular barrier membrane made of polymeric materials that are used for the separation and filtration of substances based on their molecular weight.

Depending on the molecular size of a substance situated in the blood, we can determine if such substances can be filtered through the filtration membrane or not.

However, the lower the molecular weight of the substance, the higher their likelihood of filtration.

In the plasma, the substance that has a lower molecular weight are water, glucose, and sodium while substance associated with protein, blood cell, and platelets contains higher molecular weight.

What is the conversion factor from km. to ft.? If Joe traveled 12 kilometers, how many feet did he travel?

Answers

Answer:

The distance traveled by Joe in feet is 39,372 ft:

Explanation:

The conservation factor from km to Ft is 1 km = 3280.84 feet.

* In order to convert the value-form km to ft then we multiply the given value of the length by 3281.

*We are given that:

*Distance traveled by Joe = 12km

*Distance in feet = 12×3281

*Distance in feet = 39,372 ft

**Thus, the Distance traveled by Joe in feet is 39,372 ft.

The conversion factor from kilometers to feet is 3280.84 feet/kilometer. This means that there are 3280.84 feet in every kilometer.

So, if Joe traveled 12 kilometers, he traveled 12 * 3280.84 = 39370.08 feet.

1 kilometer = 3280.84 feet

12 kilometers = 12 * 3280.84 feet = 39370.08 feet

Therefore, Joe traveled 39370.08 feet if he traveled 12 kilometers.

Chemical energy from broken bonds is transformed into mechanical energy for muscles. The correct option is A.

What is chemical energy?

Chemical energy is the energy held in atom as well as molecule bonding.

Chemical energy can be located in things like batteries, biomass, oil, natural gas, and coal.

For instance, when humans burn wood in a fireplace or gasoline in a vehicle's engine, chemical energy is transformed into thermal energy.

Chemical energy, such as that held in the bonds of atoms and molecules, is stored energy. As a result of a chemical process, this energy is released.

Many chemical bonds throughout the body break during respiration, releasing energy. The movement of muscles is one activity that uses this energy.

Broken bonds' chemical energy is converted into mechanical energy for muscles.

Thus, the correct option is A.
