40 POINTS. BRAINIEST ANSWER, ANSWER ALL. MAKE SURE IT'S RIGHT. DON'T JUST DO IT FOR THE POINTS OR ILL REPORT UR AS

1. Humans take in oxygen and release carbon dioxide using lungs. Which organism below uses book lungs to exchange oxygen and carbon dioxide?

A. Fish.
B. Bird.
C. Spider.
D. Airplane Plant

2. The following picture shows the human circulatory system.
What is the function of the organ marked as X?

A. To filter blood
B. To pump blood
C. To add oxygen to the blood
D. To remove carbon dioxide from the blood

3. There are three types of muscle found in the body. Where are these three types found?

A. Heart, brain, skeletal muscle
B. Heart, blood vessel walls, bones
C. Heart, skeletal muscle, blood vessel walls
D. Skeletal muscle, blood vessel walls, pancreas

1. C .

A Book lung is a type of respiratory organ that is found in specific air-breathing arachnid arthropods , meaning , scorpions and some spiders.

2. B , To Pump blood.

The heart pumps blood to all parts of the body , which x points to the heart. Blood provides Oxygen and nutrients to the body removing carbon dioxide and wastes. Oxygen rich-blood then flows from the lungs back into the left atrium + left upper chamber of the heart, through four pulmonary veins.

3.  The three types are cardiac,  smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart one of our strongest muscles. So I'd say it's option C but that could be wrong.

Explanation:

i really wish i could answer this question for you

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
