What do you think happens to the oxygenated blood after it enters the left ventricle?

Explanation:

The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.

Which two substances are among the four major types of organic compounds made by living things?
A. Phosphates
B. Nitrates
C. Proteins
D. Lipids

Oxygenated blood leaves the lungs and enters which heart chamber?

A person riding a bicycle wants to move the bicycle forward. She moves her legs up and down on the bicycle's pedals. Then the rider wants to stop the bicycle. She stops pedaling and the bicycle slows. She takes one of her feet off a pedal and puts her foot on the ground to stop the bicycle and stay upright.

Which of these best identifies a pathway of systems in the rider's body, as described in this scenario?

Part A Cut off the top and one side of the milk carton as shown. Use the hole punch (or scissors) to make two holes on opposite sides of the carton. Make sure the holes are low enough for the rubber band to launch the car. Thread the rubber band through the holes, and secure it using paper clips. Stretch the rubber band to launch the toy car away from the box. Pull back the rubber band to different distances, and explain what happens.​

can someone help me w this? A pneumonic device is a memorization tool that helps you remember things. For example, if you can read music you probably have heard, “Every Good Boy Does Fine” to learn the names of the lines on the treble clef EGBDF. Or maybe your math teacher taught you, “Please Excuse My Dear Aunt Sally,” to help you remember the order of operations. It is now your turn to think of a pneumonic device to remember the water cycle in order. Write your pneumonic device below.

To calculate acceleration you must
Select one:

multiply the force and mass

add the force and mass

divide the mass by the force

divide the force by the mass

How can speed be described?
Select one:

The mass multiplied by the acceleration of an object.

The distance an object travels at a certain velocity.

The distance travelled by an object in a certain time.

Why will a sound wave travel through a solid more quickly than through a gas?
Group of answer choices

The particles in a gas are close together, which means the vibrations of the sound wave transmit more slowly.

The particles in a gas are spaced farther apart, which means the vibrations of the sound wave transmit more quickly.

The particles in a solid are spaced farther apart, which means the vibrations of the sound wave transmit more quickly.

The particles in a solid are closer together, which means the vibrations of the sound wave transmit more quickly.

Part A A compass contains a magnet. The magnet responds to Earth's magnetic field. The magnet's north pole points north from most locations on Earth. Based on what you learned about magnetic force, make three predictions, Predict the approximate size of Earth's magnetic field and the approximate location of its North and South Poles. Give a reason for each prediction​

In the Tough Man Competition, very strong men are challenged to push or pull extremely large and heavy objects to test their strength. In one such challenge, they were asked to push one of two rail cars, an engine car and a box car. The data tables show one man’s results. Look over the data table and answer the questions below.

A. Why couldn't the strong man move the box car with a force of 3000 Newtons? Make sure to include Newton's 2nd Law in your explanation.

B. What could be done to move the boxcar?

C. Another student claims that during the competition, the sum of the forces on the boxcar was 0 N. What evidence is the student using to make this claim? Be sure to explain your thinking.
