Student’s name Professor’s name Course number Date Parasites and Diseases Trypanosoma cruzi is a parasitic species of the genus Trypanosoma which causes Chagas disease in America. The condition caused by Trypanosoma cruzi, also known as American human trypanosomiasis, exists in two types in humans: as a trypomastigote in blood, and as amastigote when in cells (Sastry et al. 79). The cell structure of Trypanosoma cruzi plays an essential function during its life cycle by allowing for morph into the three types (trypomastigote, epimastigote, and amastigote) according to the location of the cell in the anatomy of the host. The cells replicate after penetration of another cell has...

Name Instructor Course Date Module 2 Fertilization Discussion No, humans cannot use mitosis for reproduction because of the following reasons. Mitosis is the procedure by which somatic cells are also known as non-reproductive cells split. It implies that only the non-reproductive cells can divide while the reproductive cells important in human reproduction cannot be divided in the process of mitosis. Somatic cells majorly make up body tissues and organs including muscles, lungs and hair cells. Reproductive cells, for example, the ova are not somatic cells and hence cannot divide through mitosis (Daily Motion, Min 3). Mitosis thus plays little to no function during fertilization since the...

Form and Function of Lungs Name Institution Form and Function: Lungs The organ chosen is the lungs which allow to transfer oxygen to the bloodstream from the environment. The location of the lungs is in the chest on either side of the heart which is used in pumping blood, makes it easy for the blood to enter and leave for oxygen transportation. Also, their location behind the rib cage facilitates the pumping since lungs have no muscles to pump, but rib cage does. The base of the lungs is flatter where they meet with the diaphragm which powers most of the breathing work (Newman, 2018). Lungs are bellow-like shaped that allows that to expand and contract. The expansion enables the sucking of the...

Student’s Name Professor’s Name Course Date Enzyme activity Introduction Enzymes are the catalysts which speed up chemical reactions. Their compounds are proteins, and their role is essential for digestion of carbohydrates and lipids. The best-known enzymes belong to the digestive system, and they break down substances into their compounds so that their absorption in the small intestine is successful. That is because complex substances cannot pass the cellular membrane and pass through the small intestine to the bloodstream to nourish the body. For example, amylase breaks down starch into sugars; maltase breaks maltose into glucose and lactase breaks lactose into galactose and glucose...

Student’s Name: Professor’s Name: Course: Date: Golgi Apparatus: The Structure and Function of the Golgi apparatus They are also known as the Golgi complex and represent a stack of flattened sacs found within cells of both plants and animals. They are pancake-shaped with a cavity known as cisternae. They provide a point of connection between the endoplasmic reticulum and the plasma membrane. They operate through the transfer of material from one side to the next from one sac to the next. Movement of products can also occur in a sac which then moves to the other side without transferring the material to other sacs along the way. Golgi apparatus are organelles found in eukaryotic cells. Its...

NAME: INSTRUCTOR: COURSE: SELECTIVE PERMEABILITY The experiment put to question the selective permeability of water, starch, glucose, and iodine (Student helper, 2018 para.1). The wake of this trial is that this bag is permeable to iodine. Proceeds of the experiment no doubt answer the problems. The hypothesis is that iodine will get into the bag because it is permeable to iodine. During the summation of iodine to a liquid containing starch, it turns blue-black or purple contrarily it remains yellow (Student helper, 2018 para.19). The dialysis tubing is a semipermeable membrane that shows the detachment techniques and movement of molecules across a membrane. The bag represents a cell membrane....
