Answer:
Stress
Explanation:
Environmental stressing agent such as starvation or exposure to toxic chemicals may cause the Phage Lambda to excise and enter the lytic cycle.
<em>When water is abundant:</em>
-Temporal regulation of stomata is used:
Open during the day
Closed at night
- At night, there is no photosynthesis, so no demand for CO2 inside the leaf.
- Sunny day = demand for CO2 in leaf is high = stomata wide open.
- As there is plenty of water, plant trades water loss for photosynthesis products.
- If the leaf's CO2 concentration is low, the stomata will stay open to continue fueling photosynthesis.
- High temperatures will also signal stomata to close.
- When limited water is available in the soil, plants try to prevent water loss.
This scientific study revealed that predation is the dominant factor affecting prey population on cycling. Population cycles is the feature where populations rise and fall over a predictable period of time. For example there are some species where population numbers have reasonably predictable patterns of change. From the study depicted in the question; when snowshoe hares are scarce, many lynx leave their home range in search of food. An increased predation of the hare due to high populations of lynx and other predators increases the decline in the hare population.
Answer:
Option A
Explanation:
Corona is defined by the strong magnetic fields. When these strong magnetic fields confine solar atmosphere and produces violent bubble of gases then it is said to cause coronal mass ejection (CME).
When a CME passes through the solar wind, it causes production of high velocity solar energetic particles that follow magnetic field lines and passes through the space between the Sun and the Earth. The charged particle added by CME intensifies the solar wind.
Hence, option A is correct
