"what factors do you think contribute to animals being exposed to toxins? how can individuals prevent exposure?"

tiny-mole [99]

Depending on whether the animals are in nature or in a home environment, the factors that contribute to animals being exposed to toxins are man-made. Factories contaminate air and water. Combustion from engines pollutes the air. Garbage that is disposed contaminates the air, water and land. Often times, the lure of food for any animal, is what brings the animal into closer human contact, thus increasing the exposure to toxins. For a pet, the home environment and the decisions the pet owner takes to have chemicals like cleaners, fertilizers or pesticides and like motor oil increase exposure to toxins.

Individuals can prevent exposure for themselves and their pets by decreasing the use of motor vehicles, reducing the amount of garbage and trash produced, being a informed consumer who attempts to purchase more organic, Earth and animal friendly goods and services. Boycott corporations which contribute to the decline of the environment and increase exposure to these toxins. Other simpler ways, in environments with smog or other industrial pollutants, wearing clothing that covers most of the body, including breathing masks, gloves and glasses or goggles.

How does the foot of a bivalve differ from the foot of a cephalopod, or the foot of a snail? In what ways do these differences r

stira [4]

Answer:

Bivalve- Wedge shaped foot

Snail- Large and flat foot

Cephalopod- Foot is modified into siphon.

Explanation:

Molluscs are predominantly marine animals with a soft body,however,they are known to inhibit fresh water as well as terrestrial habitat.

They possess a *muscular foot*,which is used for *locomotion and anchorage*,they vary in shape and function depending on the type of mollusc.

MODIFICATION OF FOOT IN MOLLUSCS:

Bivalve- Foot is usually wedge shaped

Snail- Foot is large and flat

Cephalopod: Foot is modified int a siphon( a tube-like organ)

ADAPTATIONS OF FOOT IN MOLLUSCS

1)Bivalves have pointed retractable foot(wedge foot) that protrudes from the wheel and is adapted for *moving or burrowing*.

2)Snail have a mucus-laden muscular foot adaptation,that reflexes and contracts allowing movement(*crawling*) in water and terrestrial habitats

3)The foot of cephalopod is adapted for *moving* about by a kind of jet propulsion in water.
