Answer:
The river will increase Beijing’s water supply, which is currently at risk of not meeting the city’s needs. This increase will help to soften the effect of droughts.
The downside of the new river is that it may disrupt natural areas, including habitats for plants and animals. The project will also be expensive and may take up space that could be used for homes, businesses, or agriculture.
luteinizing hormone
Ovulation. Estrogen levels peak towards the end of the follicular phase. This causes a surge in levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This lasts from 24 to 36 hours, and results in the rupture of the ovarian follicles, causing the oocyte to be released from the ovary.
hope this helps :)
Answer:
Blood is not present in the urine of healthy person since the blood cells, platlets and plasma proteins are large enough to prevent their glomerular filtration. These components of blood are not present in the glomerular filtrate and hence, are absent in urine as well.
Explanation:
The first step in urine formation is glomerular filtration which filters the nitrogenous wastes and other compounds and forms glomerular filtrate. Glomerular filtrate undergoes tubular reabsorption and tubular secretion to form urine.
The components of blood such as blood cells, platelets, proteins of plasma are not added to the glomerular filtrate. They exit the glomerulus of nephrons via efferent arteriole. Since blood components are not filtered to become part of glomerular filtrate, blood is absent in the urine of a healthy person.
The scientific method can best be described as a plan or set of procedures.
