Q

Lymphatic Filariasis/ elephantiasis

A

Nematoda/transferred by mosquito vector’s/infected lymph nodes/causing swelling of lymph nodes vessels/use insect repellent

23
Q

River blindness/onchocerciasis

A

Nematoda/transmitted by the bites of blackflies/live in skin often migrate to the eye/use insect repellent and nets

24
Q

What are examples of phylum Annelida

A

Segmented worms/Leach and roundworm

25
Q

Lancelots

A

In vertebrae’s/have all four common characteristics throughout life/can swim but usually stay buried/suspension feeders/ closest living in vertebrae’s to vertebrae’s

26
Q

New world monkeys

A

Central and south America/all are arboreal/long tail for grabbing trees/nostrils wide open and far apart/endangered due to re-four station/examples Golden lion to Maren and spider monkey

27
Q

Apes

A

Diverged from monkeys 22 to 25,000,000 years ago/Lack tail long arms and legs/mostly vegetarian/larger brains/higher degree of social organization and intelligence

28
Q

Fish

A

Creates slash have a stream lined body/use gills/produce slime to help protect them from infection/lateral lines sense disturbance in the water such as vibrations of moving pray or predators

29
Q

Hominoids

A

Humans and for other groups of apes are they are gibbons gorillas orangutans chimpanzees/humans closely related to chimpanzees

30
Q

worm phylum

A

Platyhelminthes are flatworms/Nematoda are roundworms/and Annelida are segmented worms

31
Q

Fish: hagfish and Lambrays

A

Only jawless fish/notochord is main support/Craney rates/hagfish have no backbone/lampreys have poorly developed a backbone/lamp Ray have rasping mouth that attaches to fish and socks blood

32
Q

Fish sharks and raise/CHONDR I CHTHY AAN S

A

Flexible carrilage/skeleton no bones/sharks are fast swimmers, adapt predators, good sense organs/Rays adapted to life on the bottom of ocean, lie half buried most of day, sharp spine with venom glands

33
Q

Common cordate characteristics/Vertebrae’s and in vertebrae’s

A

Dorsal hollow nerve cord/notochord is stiff but flexible rod of cells along the dorsal side on their bodies/retail that extends beyond the Enis/pharyngeal slits or pouches

34
Q

Fish, Ray finned fish

A

Skeleton made of bone, cartilage reinforced/fins supported by thin flexible skeletal raise/operculum protective flap that covers the gills/swimbladder gas filled sac that helps keep them boy and in water/example trout goldfish

35
Q

Protostomes

A

First mouth

36
Q

Coelom

A

Completely lined tissue derived from mesoderm

37
Q

Coelom ate

A

True coelom, segmented worms

38
Q

Psuedocoelomate

A

False coelom, acts like one but isn’t, roundworm

39
Q

Acoelomate
