A is the correct answer I belive
Since it has 4 protons, it must have an atomic number of 4. (That makes it beryllium.)
Since it has a 4 protons and 5 neutrons, it has a mass number of 9.
Answer:
crude oil (petroleum) is the only natural liquid fossil fuel
The correct answer is soul fertility. Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality.[1] A fertile soil has the following properties:[2]
The ability to supply essential plant nutrients and water in adequate amounts and proportions for plant growth and reproduction; and
The absence of toxic substances which may inhibit plant growth.
the source of the filtrate is Loop of Henle.
The Henle loop is surrounded by tissue fluid with a high ion concentration. Osmosis causes water to move out of the descending limb. As a result of the more concentrated filtrate, ions move out of the loop in the thin ascending limb.
The nephron consists of a single long tubule and a ball of capillaries called the glomerulus. Using hydrostatic pressure, plasma is forced through the walls of the glomerulus, becoming filtrate as it crosses, and then collecting within Bowman's capsule. The fluid that enters vertebrate nephrons is called the filtrate.
<h3>Which part of the nephron is called the loop of Henle?</h3>
A million nephrons are the filtering units of the human kidney, which is a complex and highly vascular organ. Each filters water and solutes from the blood that flows through it into the surrounding space and is the cavity between the cup's walls. The other part resembles a U-shaped loop that transports the filtered fluid deep into the medulla.
<h3>Functions of Nephron</h3>
The primary function of the Nephron is to flush out waste products from the blood, which include solid waste and other excesses. This blood is transformed into urine through secretion and excretion.
The nephron, a basic structural unit of the kidney, is a microscopic structure composed of a renal corpuscle and a renal tubule.
