Answer:
Protosomes
Explanation:
Protosome is a multicellular organism whose mouth grows before the anus from a primary embryonic opening which includesphyla mollusk, arthropod or annelid. Protosomes are developed by spiral cleavage during embryo development.
Protosome animals have bilateral symmetry and three germ layers. Some of the examples of protostomes are snails and slugs (mollusk), earthworms (annelids), and spiders, lobsters, barnacles (arthropods).
Hence, the correct answer is Protosomes .
The correlation between thirst and kidney function is the following:
Thirst is the regulator of the state of hydration, necessary to eliminate the osmotic load, it can help preserve kidney function.
The instantaneous perception of osmolarity in the blood allows us to generate the sensation of thirst.
In other words, this sensation is in turn caused by a high concentration of osmolytes (compounds that affect osmosis, or the way it is measured, osmolality or osmolarity) or by hypovolemia.
The receptors that control cellular dehydration are called osmoreceptors and are located in the lateral preoptic area.
Osmoreceptors detect this decrease in cellular water and trigger thirst, as well as the release of Anti-Diuretic Hormone into the bloodstream.
Antidiuretic hormone helps regulate the amount of water in the body by controlling the amount of water excreted by the kidneys.
Therefore, we can conclude that the sensation of thirst appears the sodium concentration is higher than normal, when drinking water, the concentration gradient is reduced, which allows the normal functioning of kidney function.

Explanation:
Positive feedback occurs to increase the change or output: the result of a reaction is amplified to make it occur more quickly. Negative feedback occurs to reduce the change or output: the result of a reaction is reduced to bring the system back to a stable state.
The blood is collected in heparinized capillary tubes to prevent clotting. Heparin is a blood thinner and this anticoagulant is produced naturally by mast cells and basophils. But heparin can not dissolve or break the preformed clots.
The answer is False. The mediastinum is not a cartilage that
forms the lower portion of the breast bone, the mediastinum is the middle part
of the chest cavity, which is located between the lungs of an individual. The
Mediastinum is the area located between the lungs, it contains organs such as
the heart and its large arteries and veins. It may also include the trachea,
the esophagus, the bronchi and last but not the least the lymph nodes.
