Answer:Luteinizing Hormone
Explanation:Luteinizing Hormone (LH) is a gonadotropin synthesized and secreted by the anterior pituitary gland in response to GnRH. Like FSH, LH is involved in reproductive processes in both males and females. When follicle maturation is complete, an LH surge triggers ovulation.
Breakwaters protect an anchorage from the effects of weather and longshore drift, while jetties protect against erosion, by keeping the waves from sweeping the sand away. Difference, they both protect against different things.
The rate-limiting step for the secretion of secretory proteins or the appearance at the plasma membrane for membrane protein is generally thought to be the rate of exit from the ER. Biosynthesis in or at the ER, including folding, modifications, and assembly, hence is the most crucial step for efficient secretion.
Answer:
<h3>In mammals, <u>air is warmed and humidified in the nasal cavity.</u> Air then travels down the pharynx, through the trachea, and into the lungs. In the lungs, air passes through the branching bronchi, reaching the respiratory bronchioles, which house the first site of gas exchange.</h3>

Answer:
The correct answer is: Type 1 Pneumocytes, and Type 2 Pneumocytes.
Explanation:
The alveoli are structures that form a hollow cavity and are found in the lungs. Alveoli have the very important task of gas exchange, in which deoxygenated blood becomes oxygenated blood to be distributed to every organ in the body.
Alveoli walls are composed of two types of cells:
- Type 1 Pneumocytes have the function of gas exchange between the capillaries, and for that reason, they are very thin and permeable.
- Type 2 Pneumocytes have the function to produce surfactant, a substance very important to maintain the elastic recoil of the lungs. Without surfactant, the lungs would collapse.
