Dimas [21]

Answer:

Osmosis

Explanation:

As mentioned in the question,Pacific sea horse is an organism that face the constant challenge of losing water to their saltier environment. So if the environment is saltier it means that water will be moved from the Pacific horse' body cells into the environment to balance the concentration of salts. This process will happen when water molecules will move down the concentration gradient through selectively permeable membrane's of horse's body. This causes the loss of water from the body of horse and maintaining the salt levels of outside environment. This is called the process of Osmosis.

Here water move from an hypotonic environment (with less salts) into a hypertonic environment (with more salts).

Hope it helps!

Which chamber receives blood from the veins of the systemic circuit?

Nadya [2.5K]

<span>Right atrium The answer here requires you to know what the systemic circuit is. That's the circuit that takes oxygenated blood from the heart to the rest of the body and then returns the deoxygenated blood to the heart. With that in mind, let's look at the 4 chambers of the heart. Left atrium gets oxygen rich blood from the lungs and pumps it into the left ventricle. So we know this isn't the correct chamber and we can also ignore the left and right ventricles as well since they receive blood from their respective atriums. That leaves only the right atrium and it's definition is Right atrium gets oxygen poor blood from the body and pumps it into the right ventricle. And that does sound like the correct chamber to me. So the answer is "right atrium"</span>

Explanation:

Any blow with mechanical damage, change in temperature or pressure, UV radiation, plutonium, strontium, X-rays, electricity, loud noises is considered physical noxa.

Examples of this can be: Physical hazards: noise, radiation (ultraviolet, x-rays), electricity, blows, breaks, burns, cuts.

Chemical noxa is toxic and poisons, mostly of exogenous origin, that enter the body accidentally.

Examples of this can be: Chemical noxes: insecticides, pesticides, poisons, toxic gases, co2, co.

Biological noxas are living beings or viruses recognized as pathogenic agents, since they cause diseases of varying symptoms, evolution and severity, but which are called infectious diseases.

Examples of this can be: bacteria, protozoa, fungi and non-cellular entities, such as viruses.

Psychosocial noxas are actions or lack of actions that can cause mental disorders and that can lead to physical problems. Its impact is often negative on general well-being, particularly for young people.
