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.

Muscle contraction is an example of which of the following types of work? Group of answer choices electrical concentration heat
Citrus2011 [14]

Answer:

Muscle contraction is an example of mechanical contraction.

Explanation:

Muscular contraction is the activation of generating tension which appear in the muscle fiber as it does't change the length of muscle and is followed by muscular relaxation.

Muscle contraction is based on force and length.

The process of skeletal muscle contraction is an energy requiring process.

In order to perform mechanical work,actin and myosin  utilizes the chemical energy into ATP that ultimately require during muscle contraction and relaxation.

In a working muscle,glucose is released  from glycogen that are stored in the muscle by the process of glycolysis in which glucose broken down into ATP that is required by cells and tissues.

Evidence for coordinated stasis is found in ____.
KonstantinChe [14]

The correct answer is option (A) the fossil record.

Coordinated stasis refers to the stasis or the no evolutionary changes in the organisms for millions of years, which is followed by extinction and formation of the new species.

Fossil records have the evidence of ecological and evolutionary stability in the species over a long period of geological time scale separated by intervals of abrupt change. The best example of this being the animals of the Middle Devonian Hamilton group. Thus, fossil record is the only source of record showing this long period of stasis and separated by periods of abrupt changes in the species due to environmental pressures.
