The pitcher-plant mosquito (Wyeomyia smithii) has a genetically-controlled behavioral response to changing seasons: these mosquitos transition from an active period of growth and reproduction in warmer months to diapause, or dormancy, in cooler months. The environmental cue that induces mosquitos to enter diapause is daylength, which gets shorter towards the end of the mosquitos’ active period.In the habitat range of the pitcher-plant mosquito, regions that are further south tend to have longer periods of warmth than regions that are further north. So, the active period for mosquitos in southern regions lasts later into the year, when the days are shorter. As a result, the daylengths that induce diapause in southern mosquito populations are, on average, shorter than the daylengths that induce diapause in northern mosquito populations.Researchers have observed that climate change has led to longer periods of warmth in the pitcher-plant mosquito’s northern range.Based on the information above, which of the following best predicts the effect of climate change on the northern populations of pitcher-plant mosquitos?

Timing of seasonal activities of plants in relation to change in environmental conditions is called

As the amount of daylight decreases in the fall and winter, processes such as cellular respiration slow down so plants can conserve energy. When this happens, what stage is the plant most likely entering?A.ProtectionB.PhotoperiodismC.Day-neutral periodD.Dormancy

The tropical pitcher plant is a unique plant that obtains its nutrition by digesting insects. The plant traps insects in its pitcher-shaped leaves and dissolves them as part of the digestion process. Tropical pitcher plants grow in warm, moist places in which the soil is poor in nutrients. Because of their feeding habits, pitcher plants are able to control the insect populations in the areas in which they live. Which best describes the pitcher plant’s niche? controlling insect populations sharing a habitat with insects having pitcher-shaped leaves being a unique type of plant

A season is a subdivision of the year, marked by changes in weather, ecology, and hours of daylight. Seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis relative to the plane of revolution. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface. These variations may cause animals to go into hibernation or to migrate, and plants to be dormant. It is scientifically fascinating how bears and other animals instinctively know when to hibernate. During May, June and July, the northern hemisphere is exposed to more direct sunlight because the hemisphere faces the sun. The same is true of the southern hemisphere in November, December and January. It is the tilt of the Earth that causes the Sun to be higher in the sky during the summer months which increases the solar flux.(Adapted from Wikipedia)Which sentence is unnecessary and could be eliminated without disturbing the flow and information of the paragraph?ResponsesA These variations may cause animals to go into hibernation or to migrate, and plants to be dormant.These variations may cause animals to go into hibernation or to migrate, and plants to be dormant.B It is scientifically fascinating how bears and other animals instinctively know when to hibernate.It is scientifically fascinating how bears and other animals instinctively know when to hibernate.C It is the tilt of the Earth that causes the Sun to be higher in the sky during the summer months which increases the solar flux.It is the tilt of the Earth that causes the Sun to be higher in the sky during the summer months which increases the solar flux.D Seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis relative to the plane of revolution.
