Answer:
Nitrogen can be transformed into a utilizable form like NO2 by the fixation process.
Explanation:
The conversion of nitrogen into various chemical forms is described through the Nitrogen cycle. The nitrogen of atmosphere is less usable. However, it can be made usable by various interactions of complex genes that allow nitrogen conversion by different organisms.
One such interactive process is of Fixation. In this method, nitrogen is modified into ammonia by symbiotic microorganism. They have the enzyme called nitrogenase which makes the bond of hydrogen with nitrogen to make ammonia.
the the second least force as it go it lose more and more force until it falls when it force the ball to drop the minute it hits the floor it has the least force
Correct answer: B) Production of gametes and hormones
The male reproductive system include a number of sex organs that play an important role in the human reproduction. All the male organ are located either on the outside of the body or within the pelvic region.
Male reproductive system includes external genital organs and internal genital organs . The external genital organs consists of penis, scrotum and internal genital organs include epididysis, accessory gland and vas deferens .
The main function of male reproductive system is the production and secretion of male sex hormones like testosterone which is required to maintain male reproductive system. It help in the production and transportation of sperm and discharge them in to the female reproductive system at the time of intercourse.
Answer:
1. The one nearest the surface is the "zone of aeration", where gaps between soil are filled with both air and water. Below this layer is the "zone of saturation", where the gaps are filled with water.
2. Larger pores mean less friction between flowing water and the sides of the pores. Smaller pores mean more friction between flowing water and pore walls and more twists and turns for the water to navigate. A permeable material has a greater number of larger, well-connected pore spaces. An impermeable material has fewer, smaller pores that are poorly connected.
3. A cave is any cavity in the ground that is large enough that some portion of it will not receive direct sunlight.
A cavern is a specific type of cave, naturally formed in soluble rock with the ability to grow speleothems.
4. The size of the pores underground rock material has and if the pores are connected
5. Karst regions are formed when there is a chemical reaction between the groundwater and the bedrock. As rain, streams, and rivers flow over the earth's surface, the water mixes with the carbon dioxide that naturally exists in air, and the soil becomes acidic and corrodes the calcium carbonate rock. The carbonate solution seeps into fissures, fractures, crevices, and other depressions in the rock. Sinkholes develop and the fissures and crevices widen and lengthen. As the openings get larger, the amount of water that can enter increases.
Answer:
Bacteria, Protist (Animal-like) and Protist (Fungi-like).
Explanation:
Bacteria, Protist (Animal-like) and Protist (Fungi-like) are the organisms which are unicellular and heterotroph. Unicellular are those organisms which are made of single cell and heterotrophs are those which feed or take food from other organisms. So these organisms i. e. Bacteria, Protist (Animal-like) and Protist (Fungi-like) have both qualities such as they are unicellular as well as heterotroph.
