Nucleus accumbens

acrosome is the part on the head of the sperm. It is located on the tip and it is made of chemicals. The function of the acrosome is to dissolve the membrane of the egg so the sperm can fertilize it. URL: https://goo.gl/m1bFIq Part: Nucleus Function: the function of the nucleus is to carry the 21 chromosomes to the egg to complete the 42 to be in the zygote URL: https://goo.gl/ED2A9S Part: Tail Sheath Function: Tail sheath acts as a cell membrane for the sperm URL: http://goo.gl/JZjVw8 Part:…

In the prokaryote cell, all the components of the cell are in the cytoplasm because they do not have a cell nucleus but in the eukaryote cell, the materials in the cell nucleus are separated from the cytoplasm. It is dominated mainly of water, but there are some enzymes like protein salts, organelles (mitochondria, Golgi apparatus and so on) and various organic molecules. The cytoplasm helps…

The Mitosis Diamond I was being chased by the biggest mob of people I 've ever seen. I was having to dodge arrows and axes it was this bad. Then I was hit!!! But first let me tell you about the beginning. It all started on a beautiful summer day at my jewelry store. Well let me go to the very beginning when I found the best jewel ever. I was hiking on a famous trail in Australia and about half way on the trail I tripped. I hit my head on a rock and I hadn’t really had a good day.…

Cell Biology Beta cells in pancreatic tissues are described as eukaryotic cells and not prokaryotic, this is because the cell is larger in size and there is a true nucleus present which contains DNA. In prokaryotic cell there isn’t a nucleus and the DNA is free within the cytoplasm. Also Beta cells have many organelles and there is mitochondria present, which in a prokaryotic cell there are fewer organelles and there aren’t any mitochondria present. Beta cells in the pancreatic tissue release…

FTO belongs to a member of Fe(II)- and α-ketoglutarate-dependent AlkB dioxygenase family and was originally recognized as an enzyme involved in the excision of N1- or N3-modified purine or primidine in both DNA and RNA substrates. Jia et al. for the first time demonstrated that human FTO could also demethylate m6A on nuclear RNAs in vitro, and increase and decrease in m6A was manifested in FTO-depleted and overexpressed-HeLa cell, respectively. FTO function has shown to link to the regulation of…

Lab 4: Osmotic regulation of cell volume The eukaryotic organism requires homeostasis to maintain daily activities and life. Zooming into smaller units to make up an organism, cells also require homeostasis in order for the organisms to function. Understanding the different balance cells need to maintain will aid us in understanding how cells in organisms successfully maintain osmo-regulations. Eukaryotic cells have selective permeable membrane giving them the unique function of regulating…

where DNA is structurally in the cell is different between prokaryotes and eukaryotes. In prokaryotes, the DNA is in the cytoplasm, but specifically it is concentrated in the nucleoid region. In eukaryotes, the DNA is all contained and stored in the nucleus. Prokaryotes and eukaryotes also contain ribosomes. Ribosomes are small, roughly spherical organelles without a membrane that are responsible for assembling and building protein. Ribosomes are composed of protein and RNA molecules. Just like…

After being incubated in a water bath at 37 degrees Celsius for 20 minutes, the 8 samples were centrifuged at 400 rpm for 5 minutes and collected for observations. Presence of a red pellet in the first 7 tubes, including control Test Tube 1 were noted, while the red pellet was absent in control Test tube 8. It must also be noted that the pellet became progressively smaller as each successive tube was examined, a result more noticeable after examination of Test tube 5, as seen in Figure 1. The…

In 1635-1702 a physicist named Robert Hooke was the first inventor of the microscope. He first observed thin slices of cork, which he described to be as small rooms, the ones that were similar to the small rooms in monasteries. He only saw the cell wall because cork cells are not alive. After the discovery of the microscope in 1635-1702 by Robert Hooke, another microscope inventor named Anton Leuwenhoek, he discovered the microscope that can magnify things in 1675, and he also discovered the…

II. Method Concentration Gradients Experimet1: In this portion of the experiment, a beaker was obtained with 50mL of water, and it was sat until the water stopped moving. A small crystal of potassium permanganate dye was gently put into the water at the center of the beaker. Then the observation was recorded for the next 5 minutes. Experimet2: In this portion of the experiment, a beaker was obtained with 50mL of water in room temperature, and a teabag was placed into a beaker of water. The…
