Answer:

A.)

Genetic differences permitted some mosquitoes to become immune to DDT.

Explanation:

DDT-resistant mosquitoes were first detected in India in 1959, and they have increased so rapidly that when a local spray program is begun now, most mosquitoes become resistant in a matter of months rather than years.

Hope this helps you out : )

Answer:

What are stinkhorns?  Stinkhorns are mushrooms that are found from the tropics to more temperate regions such as Wisconsin.  They can suddenly appear in mulch, lawns, and areas with bare soil.  These visually-shocking fungi get their common name from their characteristic, unpleasant odor.  Although they are often unwanted additions to home gardens, stinkhorns do not cause plant disease.  Because stinkhorns can grow on dead organic material, they actually are beneficial in that they contribute to the recycling of plant debris into nutrients that improve soil fertility and can be used by garden plants.

What do stinkhorns look like?  Stinkhorns grow into various shapes, but they are bestknown for looking like horns or penises.  A few species grow several appendages, resulting in an octopus-like appearance.  Some species have a veil attached below the cap that resembles a lacey skirt flowing from the mushroom’s hollow stalk.  Stinkhorns can range in color from white, beige, and olive to bright orange or red with black accents.  The tips of mature stinkhorns are usually coated in a spore-containing slime.  Gardeners often discover immature stinkhorns as they dig in the soil.  The immature forms appear as whitish to pink or purple, egg-shaped masses.  Stinkhorns develop rapidly sometimes growing up to four to six inches per hour, and can generate enough force to break through asphalt.

Where do stinkhorns come from?  Stinkhorns are often first introduced into a garden in organic materials (e.g., soils and mulches) that contain microscopic hyphae (i.e., fungal threads) of stinkhorn fungi.  Once stinkhorns mature, they produce a pungent, off-putting odor that is reminiscent of rotting flesh or dung.  This smell may disgust people, but it attracts insects, particularly flies.  Flies and other insects eat the slimy material at the tips of stinkhorns and carry spores in this slime to new locations as they move around in the environment.  In many ways, this process is comparable to the distribution of pollen by bees (but of course without the more appealing scents associated with most flowers).

zavuch27 [327]

Answer:

*Sensory adaptation* is the common adaptation in all three sense. Sensory adaptation is the process in which changes in the sensitivity of sensory receptors occur in relation to the stimulus. All senses are believed to experience sensory adaptation.

Explanation:

This adaptation is shared as well as used differently as explained below.

1) Hearing+balance :In terms of hearing, our ears adapt to loud sound as it hits the small bones located in the inner ear. The loud sound leads the inner ear bone/s to contract. This contraction causes the reduction or delay of transmission of sound vibrations to the inner ear. Detection of the vibrations follows. However, this process of auditory adaptation usually does not work very well with loud sounds that are sudden or instantaneous. Examples of these sounds are gun shots or explosions

2)Smell :Low concentrations of several chemicals present in the air can be detected by the sensory receptors in the nose. These chemicals that we quickly detect include those in perfumes or air fresheners
