Like all other reptiles, birds have scales. Also, birds lay eggs like other reptiles.
Answer: Option B. "Deep"
Explanation:
Thermohaline circulation helps to drive the global conveyor belt, which is a global-scale system of currents. Due to the movement of ocean currents through different polar regions, it allows depletion of nutrients and carbon dioxide at surface waters and get enrich again as move through deep waters in the conveyor belt.
Winds in the ocean helps to drive ocean currents in the upper ocean’s surface and these ocean currents moves below the ocean surface as well. the process that controls the movement of ocean current deep in the ocean is called Thermohaline circulation that is based on differences in the water’s density, and controlled by temperature (thermo) and salinity (haline).
Thermohaline circulation forms in the polar regions of Earth. Ocean water in the polar region gets colds that allows the formation of sea ice, which in turn make the surrounding seawater saltier and increases the ice density and sinks. This allows the deep-ocean currents to drive the Global conveyer belt.
The conveyor belt starts from the surface of North Atlantic pole, where seawater become saltier and ice starts sinking. This deep water heads south along the western Atlantic basin. The conveyor belt get recharged as it travels along the coast of Antarctica and carries more cold, salty, dense water. The current get divided into two different sections, one traveling to the Indian Ocean and the other moves into the Pacific Ocean. The two sections of the current get warm and rises, as they travel northward, then turn back around westward and southward.
The warmed surface waters continue to circulate around the globe and follows depletion of nutrients and carbon dioxide. But they get enrich again when they travel through deep waters all around the the Global conveyer belt.
Hence, the correct answer is option is B "Deep".
Answer:
The correct option is 'C' that is eventually the population stop increasing or would decreases due to lack of food and living space.
Explanation:
In 1798, he wrote an essay on Principle of population where he described that how the population will grow with economy.
He claimed that the population will grow until the food supply decreases and then the population will stop growing due to lack of food and space and those individuals that can fight against this condition and and could attain food, space and other essential necessities will survive.
A. Fine Focus.
B. Nucleus, Cytoplasm, and membrane
C. 30 Micrometer.
Erythrocytes are well known to have no nucleus but in fact, they lack most organelles such as the Golgi apparatus endoplasmic reticulum and mitochondria. Hair consists of two parts the root and the hair shaft. The root is the part of the living hair located in the middle layer of the skin the dermis.
Epidermal root cells in some plants produce root hairs and tubular growths that increase the surface area of the root. Unlike other cells in the body, red blood cells do not have a nucleus. This habit dates back to when mammals began to evolve. Other vertebrates such as fish reptiles, and birds have erythrocytes that contain dormant nuclei. To allow red blood cells to carry an increased load of oxygen cells evolved to function without a nucleus and other associated organelles.
