Biology

Arlecino [84]3 years ago

I think you're looking for osmosis.

Osmosis is a kind of method where substances used to flow from a place to another. Osmosis is where water molecules flow from a region of higher water potential to a region of lower water potential, through a partially permeable membrane.

A partially permeable membrane means that membrane can select what can go through or not. Also, osmosis must be the flow of water, nothing else.

Match the description on the right with the force on the left.
Marat540 [252]

Magnetic force - B.

Electrical force - A.

Gravitational force - D.

Contact force - C.

<h3><u>Explanation:</u></h3>

When a charge moves about its path, it produces a magnetic force around it. This magnetic field is perpendicular to the axis of movement of the charge and is directly proportional to the amount of charge, speed of the charge, and inversely proportional to distance between the charge and the point of measurement. Michael Faraday discovered this phenomenon.

Electrical force of attraction or repulsion is seen between the two charged bodies, or one charged body and one uncharged body which can induce charge to the uncharged body. The attraction or repulsion between the charged bodies are seen if the bodies are close enough, and this is called electrical force.

The gravitational force is also a non contact force that is seen between two bodies which is always attractive in nature and is seen between any two bodies.

A contact force like friction is a type of force that takes place only when two bodies are in contact with each other.

Peroxidase is a protein. What is this protein’s function, and how did it get its name?.
Olin [163]

Answer:

Most peroxidases are ferric heme proteins; one notable exception being the glutathione peroxidase, which is a selenium-containing enzyme. They are present in virtually all living species.

Protein has many roles in your body. It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.
