Answer:
All the choices are correct
The skin is composed of thin membranous tissue that is quite permeable to water and contains a large network of blood vessels. The thin membranous skin is allows the respiratory gases to readily diffuse directly down their gradients between the blood vessels and the surroundings. When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air.
A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs. The mechanism of taking air into the lungs is however sligthly different than in humans. Frogs do not have ribs nor a diaphragm, which in humans helps serve in expand the chest and thereby decreasing the pressure in the lungs allowing outside air to flow in.
In order to draw air into its mouth the frog lowers the floor of its mouth, which causes the throat to expand. Then the nostrils open allowing air to enter the enlarged mouth. The nostrils then close and the air in the mouth is forced into the lungs by contraction of the floor of the mouth. To elimate the carbon dioxide in the lungs the floor of the mouth moves down, drawing the air out of the lungs and into the mouth. Finally the nostrils are opened and the floor of the mouth moved up pushing the air out of the nostrils.
Frogs also have a respiratory surface on the lining of their mouth on which gas exchange takes place readily. While at rest, this process is their predominate form of breathing, only fills the lungs occasionally. This is because the lungs, which only adults have, are poorly developed.

The biggest difference is the cause. The solar wind is a constant flow of particles from the sun's corona due to their high energy gained from the sun's interior, it's like being boiled off. CME's and flares are the result of “explosive” releases of energy from the sun's magnetic field. Solar flares and solar winds originate within the sun's atmosphere, but differ greatly from one another. Satellites on Earth and in outer space allow a look at solar flares, but you cannot see solar winds directly. However, the effects of solar winds reaching Earth appear to the naked eye when the aurora borealis and aurora australis electrify the night sky.
We support each of the following correct statements with appropriate justification, indicating why or how each statement is correct.
<h3>3. A radiograph of a horse's frontal fetlock joint is called a dorsopalmar (PD) view.</h3>
Dorsopalmar (PD) view The horse's frontal fetlock joint demonstrates dislocation of the antebrachiocarpal joint with soft tissue swelling around the carpal joint
<h3>5. When performing surgery on the digestive system, we must ensure that the suture is well closed. </h3>
Yes. Endoscopic suturing is a procedure performed 100% by endoscopy, a procedure that inserts a flexible tube through the patient's oral cavity and reaches the structures of the digestive system. It is a non-invasive, safe process that does not require any cutting.
<h3>6. Oblique positions are sometimes used in radiographs.</h3>
Yes. Right and Left Anterior Oblique Positions (RAO and LAO) These terms refer to oblique positions in which the right or left anterior side of the body is close to the RI, and can be in an upright or recumbent position.
