Answer:
Option D
Explanation:
Options for the question
A)import seeds produced in the southern hemisphere.
B)plant the flowers out-of doors in november.
C)keep the plants in a warm growing environment.
D)expose the plants to an hour of light in the middle of each night until the end of april.
Solution
Since Chrysanthemum is a short-day plant, its flower mainly develop during night and hence they require long nights of 11 to 12 hours. Blackout system is sometimes used to induce flowering.Flowering can be delayed by regulating both light and temperature. this is done by exposing plants for a short period of time to light (can be artificial) and to some source of heat that produces 85° F or higher temperature.
Thus if flowers are required in month of may, flowering can be delayed by exposing Chrysanthemums plant to light and heat source during night time

Answer:
endocytosis
Explanation:
Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested material.
Biodiversity is a term used to describe the enormous variety of life on Earth. It refers to every living thing, including plants, bacteria, animals, and humans.
Answer:
The correct option is B <em>Pressure-sensitive baroreceptors uses tonic receptors which adapt slowly to the stimulus</em>
Explanation:
a. The thalamus receives stimulus from all of the five senses (sight, smell, taste, hear, touch). FALSE. Olfactory information is not sent to the thalamus for its process. The rest is.
b. Pressure-sensitive baroreceptors uses tonic receptors which adapt slowly to the stimulus. TRUE. Among the different types of tonic receptors, we may find baroreceptors, irritation receptors, tactile receptors, and proprioceptors. Tonic receptors characterize by their slow adaptation to the stimulus. The first discharge is maximal when the stimulus is received and then it progressively decreases. They send a continuous signal to the CNS.
c. The three layers that the retina is made of: photoreceptors, bipolar cells, rod cells. FALSE. There are in fact three layers in the retina: photoreceptors, bipolar cells, and ganglion cell layers. NOT rod cells.
d. The sense of smell uses phasic receptors which continuously fire as long as the stimulus is present. FALSE. Olfactive sense uses phasic receptors, but not continuously. These receptors shoot when they receive the stimulus, and then cease if the stimulus keeps constant.
