Answer:
A. Plants will only flower during long day periods when the day length exceeds their necessary photoperiod
Explanation:
Photoperiodism is a phenomenon that refers to the response of an organism to the length of day. This phenomenon causes a physiological change in the organisms involved (plants or animals). However, the best studied example of change caused by photoperiodism is that of FLOWERING IN PLANTS.
Different plants flower at different times in response to the day length. Certain plants called LONG DAY PLANTS e.g. spinach and potato etc only flower when the length of day exceeds their photoperiod (threshold), which is usually 12 hours. These plants require very short periods of darkness to flower.
Hence, according to the question, FLOWERING response in plants is the best explanation to describe photoperiodism.
Answer:
B. Both move across the sky from east to west.
C. Both change positions in the sky due to Earth's revolution.
E. Both appear in different positions in the sky due to Earth's rotation.
Explanation:
Sun and stars doesn't move in the sky. We see sun and stars move from east to west, it is due to the rotation of earth, not the movement of sun and stars.
Sun and stars are luminous objects, so only sun is visible at daytime and starts are not because sun is more luminous than stars.
Answer:
Plants have two main types of asexual reproduction: vegetative reproduction and apomixis. ... Bulbs, such as a scaly bulb in lilies and a tunicate bulb in daffodils, are other common examples of this type of reproduction. A potato is a stem tuber, while parsnip propagates from a taproot.
Explanation:
Why this late its about to be 12 am in my country
B, because it's not an advantage for something to be expensive and time consuming
Answer: two major steps: transcription and translation
Explanation:
Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.
