Chrysanthemums are short-day plants. select conditions in which you expect chrysanthemums to flower.

SpyIntel [72]

Due to the information that they are short-day plants, I would expect chrysanthemums to flower during the times of the year when days are shorter and nights are longer.

Plants require sunlight to grow and flower or produce fruit. While some plants require more light than others, almost all plants require some form of light to survive, much less flower. Pants are often classified according to the amount of light that they require, these classifications are:

Day-neutral plants
Long-day plants
Short-day plants

Day-neutral plants are those that can flower regardless of the amount of light that they receive. These are very resistant species of plants that can thrive even through periods of prolonged darkness. Though they do well with even a small amount of light, they will still require it to survive. One example of this kind of plant is the tomato.

Long-day plants are, as the name may suggest, plants who thrive when the days are longer. These plants will not survive or bloom without many hours of sunlight every day. The optimal conditions for this kind of plant are meet during the summer, when the Earth is tilted towards the sun, causing longer days.

Finally, short-day plants are those who require little sunlight to flower. These are different from day-neutral plants in that during days with many hours of sunlight, they will not flower. These plants, such as the chrysanthemums, will only flower if daylight hours are low, meaning that spring and fall are optimal conditions for these plants to prosper.

The structure of protein molecules describe ?

artcher [175]

Proteins are polymers composed of repeating units of amino acids, linked via peptide bonds (bonds between the amine and carboxyl groups of the adjacent amino acids). All proteins have a primary, secondary and tertiary structure and some, such as haemoglobin, have a quaternary structure.

Primary structure of the proteins are the sequence of amino acids and their order. The "R" regions of the amino acids determine the proteins secondary tertiary and quaternary structures.

In the secondary structure, the protein folds into either an alpha helix or a beta pleated sheet. This occurs due to hydrogen bonding between the "R" group of the amino acids.

The tertiary structure gives the protein its 3D shape. Here it is folded further and more bonds (such as disulphide bonds) also form.

In the quaternary structure, prosthetic groups (e.g. a haem group for haemoglobin) is added. If the protein has more than one protein chains, here the chains join to form the final protein.
