Answer:
Protein
Explanation:
It has nitrogen, hydrogen, oxygen, carbon, and sometimes small amount of sulfur
The question does not have the option which are:
depleted in red light; inactive form
enriched in red light; active form
depleted in red light; active form
enriched in red light; inactive form
depleted in red light; inactive form
Answer:
depleted in red light; inactive form
Explanation:
The understory is the lower portion of the forest canopy which is characterised by the shade-tolerant species of the plants.
The light that reaches the lower portion or in the understory is depleted in the red light wavelength.
The phytochromes are the photoreceptor or blue-green pigment which response to the red and far-red wavelength. The low light converts the phytochrome to its inactive form Pr form which is reversible.
Thus, the selected option is correct.
Ok, a few things here:
This is an egg drop experiment, so I'm assuming you are testing out different ways of protecting the egg.
The independent variable is what you want to change: This would be the type of protection you have on the egg
The dependent variable is what would be effected by the changes in the independent variable: which would be something like the integrity of the egg after it hits the ground. You'd have to measure that somehow.
There are two types of controlled variables: <em>Internal and External.</em>
Internal variables are within the scope of the experiment and can be controlled, whereas external variables are outside the scope of the experiment and we have no control over them.
Internal:
- Height of the drop
- Type of egg
- Person dropping
- How the egg is dropped
- Surface being dropped on to
External:
- The person designated to drop the egg is sick
- You run out of eggs to drop
- Somebody loses all the planning for the experiment
- The weather forces you to do the experiment inside versus outside
- The wind blows your egg off course, leading to it hitting the ground at an angle
So, the way your teacher "chucks" the eggs off the roof should be a controlled internal variable. The action should be done as consistently as possible to avoid an uncontrolled variable.
The answer is C. Continental Tropical, Hope this helped!
