What part of the bone is responsible for producing red blood cells?

Soft marrow

Joints

Skin

Muscle

Soft marrow
The bone marrow is the soft, spongy tissue with many blood vessels that are found in the center of some of your bones, such as the thigh and hip bones. It contains stem cells that develop into red blood cells that carry oxygen throughout your body.

 What is the term for an animal that mainly eats meat? 

Omnivore

Carnivore

Herbivore

Predator

What organ works with your heart to supply oxygen to your body? 

Brain

The lungs

Kidney

Stomach

The lungs
The right side of the heart collects and pumps blood to the lungs. The lungs refresh the blood with a new supply of oxygen, thus its reddish color. 

It is the force that pulls any two objects together.

Gravity

electricity

Volume

Weight

Gravity
Gravity is the force with which the body draws objects towards its center. The force of gravity keeps all the planets in orbit around the sun.

What is the fibrous connective tissue that attaches muscle to the bone?

Veins

Elastic
