Create a visually appealing and educational image related to biology. It should feature a stylized representation of different species displaying distinctive structures and traits. This includes: a human able to wiggle their ears, a deer listening for predators, a human with a tail bone, a lizard with a balancing tail, a fearful human with goosebumps, an aggressive cat with raised hackles, a person standing upright supported by their pelvis, and a snake with a tiny nonfunctional pelvis. Also include a demonstration of vertebrate categorization, showing an octopus, a shrimp, a fish, and a crab. Additionally, embody an embryo development comparison among fish, amphibians, reptiles, birds and mammals. Finally, include a depiction of adult vertebrates presenting homologous structures such as a backbone.

Question Number 1:

Humans have a lot of homologous structures in common with other animals, and several of these structures are no longer in working order in human bodies. These nonfunctioning structures are called vestigial structures. They still show evidence of common ancestry, but they do not do the same things in humans as they do in other animals.

Listed below are mostly vestigial structures. Select the one that serves a purpose in humans.

A. ear muscles: ability to wiggle ears in humans versus rotating ears to hear predators in prey animals like deer and rabbits

B. tail: tail bone in humans versus long tails for balance and communication in other animals like lizards and wolves

C. hair raising: goosebumps in humans versus raising hackles to appear larger and aggressive in other animals like cats and monkeys

D. pelvis: supports upper body and attaches to lower body in humans versus being tiny and nonfunctional in legless animals like whales and snakes

Question Number 2:

Which animal is a vertebrate?

A. octopus

B. shrimp

C. fish

D. crab

Question Number 3:

Fish, amphibians, reptiles, birds, and mammals have similar embryos.
They all start with gill slits. Fish and some amphibians grow to have gills. Some amphibians, reptiles, birds, and mammals develop lungs to breathe air.
They all start with tails. Fish, some amphibians, reptiles, and birds grow tails. Humans do not keep their tails.
Fish and reptiles develop scales. Amphibians, birds, and humans have skin. Birds have feathers, and humans have hair.

With which animal do humans exhibit the most linear relationship?

A. birds

B. fish

C. amphibians

D. reptiles

Question Number 4:

What is a homologous structure that humans share with other vertebrates when they are fully grown?

A. spine

B. gills

C. hair

D. tail

A. Pelvis..etc

B. Fish

C. Birds

D. Spine

100%

Hey Bugaboo is correct

1. pelvis: supports upper body and attaches to lower body in humans versus being tiny and nonfunctional in legless animals like whales and snakes

2. fish
3. birds
4. spine
Have an amazing day!

Thanks bugaboo 💕

Anonymous is right for all except c and c is birds

hey bugaboo is 100% correct i just took the quiz and got 4/4

yooo thanks;)))

thankssssss

none of yall is right

bugaboo is correct thanks
