when undergoing meiosis, during metaphase the chromosomes line up in the middle of the cell so that in anaphase, it can be easily and evenly divided among the two daughter cells
In our solar system, the sun is our closest star and it’s huge. Around 1 million earths can fit inside the sun to show you that perspective.
The sun glows so brightly because of nuclear fusion. Nuclear fission is a certain type of reaction and it releases enormous amounts of energy. Very small particles of mass create thermal energy.
Answer:
B. Ribosome
Explanation:
Ribosomes are the organelles that serve as a site for protein synthesis. Each ribosome has two subunits. The small subunit first joins with mRNA and the initiator tRNA to start the process of protein synthesis. The large subunit joins the complex and the proteins are synthesized according to the nucleotide sequence of the mRNA read in the form of genetic triplets. Ribosomes are present in cytosol as well as on the surface of the rough endoplasmic reticulum of a eukaryotic cell. In both locations, they are involved in the process of protein synthesis.
In the Asian culture, they have a formal respect system where they maintain a distance from others. Many are uncomfortable with a direct eye to eye contact. The patient is not being rude, they are only doing as their culture dictates. With this being said, the nursing action that is most appropriate is to continue with the instructions and conversation. If the nurse decides to walk around to face the patient, this is considered a direct conflict in their culture. Do not stop giving the instructions on the stool specimen and offer the patient to come back as they will be offended. Also, never tell the Asian patient to look at you as you are talking as they may find it degrading. So the answer to the question is; continue with the instructions and verify that the client understands.
Answer:
Generally, mammals have a pair of bran-shaped kidneys. The mammalian kidney has 2 distinct regions, an outer renal cortex and inner renal medulla. Both regions are packed with microscopic excretory tubules, nephrons, and their associated blood vessels. Each nephron consists of a single long tubule and a ball of capillaries, known as glomerulus. The blind end of the tubule forms a cup-shaped swelling called Bowman’s capsule, that surround the glomerulus. From Bowman’s capsule, the filtrate passes through 3 regions of the nephron which are proximal tubule, the loop of Henle. A hairpin turns with a descending limb and an ascending limb and the distal tubule. The distal tubule empties into a collecting duct, which receives processed filtrate from many nephrons. The many collecting ducts empty into the renal pelvis, which is drained by ureter.
For the structure of nephron, each nephron is supplied with blood by an afferent arteriole, a branch of the renal artery that subdivides into the capillaries of the glomerulus. The capillaries converge as they leave the glomerulus, forming an efferent arteriole. It is surrounded by the Bowman’s capsule. The double-walled epithelial Bowman’s capsule is formed by the invagination of the blind end of the nephron. The glomerulus and Bowman’s capsule form the first region of the nephron and is known as the renal corpuscle or the Malpighian body. The capillary walls are composed of a single layer of endothelial cells with openings between them with a diameter 50-100nm. These cells are pressed up against basement membrane which completely envelops each capillary, separating the blood in the capillary from the lumen of Bowman’s capsule. The inner layer of the Bowman’s capsule is composed of a cell called podocytes which have arms that give off structures resembling tube-feet called foot processes or secondary processes. The secondary processes support the basement membrane and capillaries beneath it and gaps between the processes (slit pores) facilitate the process of filtration. The Malpighian body leads into the remainder of the tubule.
