Answer:
calcitonin
Explanation:
Calcitonin is a hormone which helps in lowering the high blood calcium levels. It is secreted by thyroid glands. Parathyroid glands are responsible for increasing calcium level in the blood while calcitonin hormone work against parathyroid glands and helps in lowering calcium level. Calcitonin hormone inhibit the activity of osteoclasts which are responsible for releasing of calcium from bones into the blood.
The answer is ultrafiltration. This is helped by the hydrostatic pressure and blood pressure in afferent renal arteriole. Molecules such as water, glucose, urea, sodium chloride, amino acids pass through the semipermeable membrane of the dense capillary network of the glomerulus to form glomerular filtrate. Some of these molecules are later reabsorbed in the renal tubules.
Answer:
The correct answer is -
differences: color, brightness, temperature, size, and mass
similarities: They are balls of gas, mostly hydrogen and helium
Explanation:
Stars look mostly the same from anywhere or any place and tough to differentiate or distinguish one from another. Star can be different on the various ground even they look similar from far away.
Stars can be of various colors from red to blue and brightness can be different as well, color depends on temperature, and brightness depends on the size of the star.
Stars are grouped by the size that ranges from dwarf to supergiant. The temperature of the stars also varies which affects the color and brightness as well.
Stars are the big balls of gases composed of mainly helium and hydrogen all are always under a nuclear reaction.
Answer: Option A.
Tundra
Explanation:
Tundra biome have the lowest annual precipitation because it is the coldest of all the biomes and it is plain without trees and have frost molded land scape. It have low or poor nutrients which do not support plants growth, low temperature or have the lowest temperature, little precipitation and short growing seasons.
It's annual precipitation is less than 25 centimeter annually and they are also considered as desert, after the short growing seasons, it is followed by harsh conditions which the plants and animals present there posses a special type of adaptation for survival in the area. They are found in high altitude landmass such as Canada, Russia, Alaska e.t.c.
