Answer:
Sympathetic nervous system
Explanation:
The sympathetic nervous system of the autonomic division prepares the body for stress or emergency conditions by generating the “fight-or-flight” responses. The sympathetic nervous system triggers the release of stress hormones from the adrenal medulla to generate the set of physiological responses.
There is dilation of the pupil, and an increased rate of heartbeat and increased blood pressure. Other responses include dilation of airways and dilation of blood vessels that supply blood to skeletal muscles, heart muscles, liver, etc. Under the given emergency condition, the sympathetic nervous system of Meghan was activated to generate the fight or flight response.
Answer:
B. At the edge of the plates
Explanation:
<u>Gravity </u>is the principal <u>driving force </u>of <u>plate tectonics </u>(second one is convection<u>)</u>. It causes different density plates to move on the Earth's surface. However, when a <u>denser plate coincides the less denser plate, the high density plate subducts</u> below the <u>lesser density plate</u>. The process, therefore, is called <u>subduction</u>. During this collision of plates, <u>shearing resistance increases</u> and all <u>pressures come at the edge of the plate</u>. The process continues and the lithosphere drags the rest of the plate. The portion of plate below the less denser plate then reaches the mantle. Here, the edge of plate is destroyed due to high temperature of mantle as well as pressure.
Answer:
<u>Luteinizing hormone </u>(LH) stimulates Leydig cells to secrete testosterone
<u>Follicle stimulating hormone (FSH)</u> stimulates Sertoli cells to secrete protein and other molecules required for spermatogenesis
Explanation:
Under the influence of gonadotropin-releasing hormone, the anterior pituitary releases luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In males, LH stimulates interstitial cells of testes (Leydig cell) to secrete the hormone testosterone. FSH acts indirectly to stimulate spermatogenesis by causing the release of androgen-binding protein (ABP) from the Sertoli cells. The function of ABP is to maintain the higher concentrations of testosterone to stimulate the final steps of spermatogenesis in the seminiferous tubules.
Answer:
The correct answer will be option-D
Explanation:
The evolution of vascular tissues in plants from non-vascular plants was an adaptive feature to survive in the terrestrial environment. The group of plants in which vascular tissues evolved and developed is the Pteridophytes which contained stellar organization of the vascular bundles.
The pteridophytes exhibited xylem and phloem which allows the rapid uptake of the water and nutrients from the soil which allowed the growth of the plant and since plants got enough water and nutrients from the soil, they adapted to grow tall so that they can maximize the output of photosynthesis in bright sunshine.
Thus, option-D is the correct answer.
The type of property rights regime suits this scenario is private property regime. The land is owned by richard so this is a private land already but the government will impose some rules and regulations to it for the betterment of the environment.
