Answer:

To be put simply, bacteria can be on things that are used quite often such as toilet seats, television remotes etc. If someone does something dirty such as plant seeds in dirt and not wash their hands, the next thing they touch will have bacteria on it. If you touch what has this bacteria on it, it stays on your hand. But if you wash your hands it will be gone, but if you touch your face, mouth, nose or eyes it will travel inside you, causing harm if it is a very bad type of bacteria.

Identify the correct path for OXYGEN-POOR blood

Oksanka [162]

Answer:

The correct pathway for oxygen-poor blood is right atrium → right ventricle → pulmonary artery → lungs (first option).

Explanation:

Unoxygenated or oxygen-poor blood is that which comes from tissues that have exchanged O₂ for CO₂. The venous return is in charge of taking that blood to the heart and then to the lungs.

Oxygen-poor blood reaches the right atrium from the vena cava.
From the atrium the blood passes to the right ventricle through the tricuspid valve.
The right ventricle pumps the blood to the lungs through the pulmonary arteries, the only arteries that carry venous blood.

Once in the lungs, the blood exchanges CO₂ for O₂, returning to the heart through the pulmonary veins.

The other options are not correct because:

Left atrium, left ventricle, aorta, body corresponds to the flow of oxygenated blood that comes from the lungs and is pumped to the entire body.
Left atrium, right atrium, left ventricle, right ventricle not correspond to the order in which blood flows through the heart.
Right ventricle, right atrium, pulmonary veins, lungs not correspond to the flow of oxygen-poor blood.

BARSIC [14]

Answer:

dependent

Explanation:

The experiment is trying to find out the how the attitude of the boys changes when they are told that they are good at it.

In any experiment to find out the relation between two variables it is observed that change in which variable causes a change in the other variable.

The variable which changes irrespective of the other variable is called the independent variable.

The variable which changes because of the change in the independent variable is called the dependent variable.

Here, the independent variable is what the boys were told before playing the game and the dependent variable is their performance.

Hence, the passage in quotations makes reference to the dependent variable.
