Answer:
Disruptive selection
Explanation:
Disruptive selection favors both of the extremes ( large and small beaks) Thank me later:)
From the
books of Geography Seattle is well known for its rain and dark, gloomy skies, but
it may surprise many how pleasant the weather can be, particularly during the
summer months. Using data from meteorological services for the past 50 years,
we can conclude that November through March brings cool temperatures, heavy
cloud cover and rain falling on most days. The coldest month is January with
average lows in the mid to upper 30s F (about 3°C). Weather is pleasant from
April through October, with the best weather in July and August when highs
average in the 70s and rain is uncommon. Skies are mostly clear and smog-free,
though mornings can produce an on-shore flow resulting in low clouds and fog
which typically burns off by mid-day.
J-shape curve
J-shape curve is a curve that shows the population density of an organisms as they increase rapidly in a logarithmic or exponential form but abruptly stops due to environmental resistance. Thus, the population rate is largely determined by the biotic potentials and size of the population. However, exponential growth produces J-shaped curve.
Answer: open more frequently to allow water and CO2 into the leaf tissue.
Explanation: Oxygen and C02 enters into the leaves to gives energy and sugar as food,to enable the plant to grow.
It allows the process of photosynthesis. Photosynthesis is the process whereby green plant and other orgasm manufacture light into chemical energy. Plants through the opening of the leaves breath in carbon dioxide and breath out oxygen. While animal in the other hand breath in oxygen and breaths out carbon dioxide.
The continuous opening and closing of stomata is responsible for photosynthesis.
