Question

Examine the physical characteristics of the frog and determine if it is a vertebrate or an invertebrate. ( help, ill mark the brainliest)

Answer 1

Answer:

It is a vertebrate as it has fully developed skeletal system including a vertebral column

Answer 2

Answer:

I REALLY HOPE THIS HELPS YOU A LOT!!

GOOD LUCK.

pls mark me brainliest

Explanation:

First lets look at the physical characteristics of a frog

1. Nostrils - for gas exchange (Respiration)

Invertebrates don't have nostrils. The feature used for breathing is either the trachea or the gills. Most vertebrates have Nostrils (Not all)

2. Moist skin - Also for gas exchange (Respiration)

This feature cannot determine whether is is vertebrate or invertebrate but instead determines whether it is an amphibian or not. This is a general characteristic for Amphibians.

3. Four limbs (limbs in general) - For movement

This too doesn't determine if it vertebrate or not because both vertebrate and invertebrate animals have limbs (legs)

4. Wide mouth - For nutrition

This one is helpful when determining whether it is vertebrate or invertebrate. Because NO invertebrate animal bear a wide mouth.

*Not all Vertebrates have wide mouth*

5. Webbed hind limbs

This one can conclude it all. Only vertebrates (amphibians) have hind limbs or lets say webbed hind limbs. if not the hind only vertebrates have the webbed limbs (bird, reptile, some mammals)

6. Lacks a tail

This one definitely can't determine if it is vertebrate or invertebrate but only in terms of Amphibians or lets say frog.

If you put the frog aside you would realise that the tail is the most common feature between vertebrates and this is a very helpful characteristic that helps you determine. Absolutely NO invertebrate have a tail.

7. It has a backbone

This one is the main characteristic of a vertebrate animal. This is where their name even generates from. No

invertebrate animal have a backbone.

These characteristics have been grouped into features for only invertebrates, only vertebrates, both, only Amphibians

And, we have No. 6 in only invertebrate.

No. 1, 4,and 5 for only vertebrates

No. 3 for both

And, 2, 6 for only amphibians.

SO FROG IS  A VERTEBRATE
