Of the statements below, identify the one that best describes the relationship between plants and oxygen.
viva [34]

Answer: A. plants produce oxygen during photosynthesis and they also need oxygen from the air for cellular respiration.

In the process of photosynthesis the plants in the presence of sunlight, water and carbon dioxide produces a carbohydrates as food and oxygen is liberated into the atmosphere. The process of photosynthesis takes place in day and plants avail oxygen from the roots and leaves for respiration. The food produced is broken down into carbon dioxide and water with the release of energy in the presence of oxygen during cellular respiration. Plants produce oxygen as a byproduct of photosynthesis and use oxygen for cellular respiration.

On the basis of the above information, A. plants produce oxygen during photosynthesis and they also need oxygen from the air for cellular respiration is the correct statement that describes the relationship between plants and oxygen.

What are the steps in filament theory
Inessa [10]

Answer and Explanation:

The steps of the sliding filament theory are:

Muscle activation: breakdown of energy (ATP) by myosin.

Before contraction begins, myosin is only associated with a molecule of energy (ATP), which myosin breaks down into its component molecules (ADP + P) causing myosin to change shape.

Muscle contraction: cross-bridge formation

The shape change allows myosin to bind an adjacent actin, creating a cross-bridge.

Recharging: power (pulling) stroke

The cross-bridge formation causes myosin to release ADP+P, change shape, and to pull (slide) actin closer to the center of the myosin molecule.

Relaxaction: cross-bridge detachment

The completion of the pulling stroke further changes the shape of myosin. This allows myosin and ATP to bind, which causes myosin to release actin, destroying the cross-bridge. The cycle is now ready to begin again.

The repeated cycling through these steps generates force (i.e., step 2: cross-bridge formation) and changes in muscle length (i.e., step 3: power stroke), which are necessary to muscle contraction.

What is the greatest advantage of using different methods that result in the same outcome?
viva [34]

The advantages of using mixed method are, the pros and cons can be identified and compared for each method. Thus option B is correct.

<h3>What are advantages of using mixed method?</h3>

Mixed methods in research is an advanced form which is basically a combination of quantitative research and qualitative research.

It can help the researcher to gain a more clear and complete picture as it integrates benefits of both methods.

Mixed methods research is used in the behavioral, health, and social sciences, societal research.

Qualitative research has smaller sample size, so mixed methods research is applied for the comparative strength of externally valid quantitative research.

Mixing methods allowed to get findings in detail to the conclusion.

Using mixed methods from different data on same subject can give more credible results.  

Thus option B is correct.

A sample of marble has a volume of 6cm3 and a density of 2.76g/cm3 what is it mass
marissa [1.9K]

To solve for the mass of a substance is to simply get the

product of volume and density, that is:


mass = density * volume


 


So calculating for mass:


mass = (2.76 g / cm^3) * 6 cm^3


mass = 16.56 g
