Answer:
A negative feedback initiated by the external simuli or the products of a reaction aims to reduce the products/ output of the reaction. Hence In negative feedback the stimulus is reduced. An example of a negative feedback would be if a person had an elevated body temperature, the homeostatic response would be to lower the body temperature.
Explanation:
carbohydrates and proteins
Answer: The water levels would rise because the frozen ice caps are putting their water into the ocean. When they melt all of the water that was previously frozen is going into the ocean and raising sea levels.
In fetal life, the lungs are not expanded, so most of the blood from the right ventricle is shunted from the pulmonary artery to the aorta through the patent ductus arteriosus. With a few breaths the lungs expand, and blood flows from right ventricle to pulmonary artery into the lungs. Withdrawal of circulating prostaglandin from the mother plus bradykinins released from the expanding lung of the infant cause the ductus to close over a few minutes to hours. The closed ductus remains as the ligamentum arteriosum.
The right answer is A.
The foreshore, also called intertidal zone, is the tidal zone of the tides on the coast. The alternation of the tides which discover more or less the substrate according to the phases of the Moon determines the conditions of humidity, salinity and temperature of the foreshore.
These variations lead to a vertical ecological structuring of the foreshore in so-called supralittoral, mediolittoral and infralittoral stages. The floristic and faunistic stands of these stages are distinct, according to the requirements of organisms in water, salinity and temperature. Therefore it would be beneficial for organisms living in this period that it can live without depending on the water present in their environment since the presence of the latter is inconstant.
The foreshore is divided into several floors that correspond to different ecological conditions. These coastal stages are defined by the duration of their emergence and therefore by the level of the different tides.
