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.

The right answers are on the attached image.
Baroreflex is a reflex triggered when a baroreceptor is stimulated. In the human body, baroreceptors are found in the carotid sinuses and the sinus of the aorta. These receptors are stimulated during changes in blood pressure. Baroreceptors are sensitive to the stretching of blood vessels.
As blood pressure rises, baroreceptors transmit nerve impulses to the vasomotor center of the medulla oblongata, which is then inhibited. This results in vasodilatation of the blood vessels to reduce blood pressure.

The testes are oval organs about the size of very large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord. Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm.
