The Solar System The solar system still to this day one of the most fascinating subjects of study in the science world. In our time‚ we are one of the first generations to see the planets of our solar system up close‚ and we have been able to view evolution of these planets through time. Our solar system consists of a middle aged star called the Sun‚ 9 planets‚ about 100 moons‚ thousands of asteroids‚ millions of icy bodies‚ and many comets revolving around all of it. We can begin by looking

Bacterial cells are Prokaryotic cells. These cells have several internal structures and surface structures. The cell walls are of two types‚ gram positive and gram negative. Out of all the structures‚ the two selected structures are the cell- wall and endospores. The cell- wall of bacterial cells is found in three distinct shapes such as spherical‚ spiral and rod shaped. The cell wall of the bacterial cells is composed of the proteins and polysaccharides. This is collectively called peptidoglycan

characteristics of a healthy cell and a cancer cell is very different. Healthy cells stop reproducing when there are enough cells‚ however‚ cancer cells continue to reproduce. Due to this continued growth a tumor‚ which is a cluster of cancer cells‚ is formed. Cancer cells do not interact with other cells like the healthy cells. Healthy cells stop growing when they hear signals from the nearby cells‚ in contrast‚ cancer cells do not respond to these signals. When healthy cells get old or damaged they

a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

though a cell is the basic unit of an organism it can be pretty complex inside of one. So why don’t we try and make it a little simpler by comparing it to something we’re all more comfortable with? Take Disneyland for example! Everyone is familiar with Disneyland and how it works. Let’s see just how similar these two can be. First‚ would be the entrance gate. The entrance gate could be our cytoplasm. Cytoplasm is the jelly-like fluid that fills a cell and inside is all the other cell organelles

Assignment – Renewable Energy For my Renewable Energy Summative Assignment I chose Solar Energy from Space. I chose this topic because I have always been interested in meteorites‚ stars‚ planets; anything in space has always sparked my curiosity. Therefore‚ I took the opportunity to learn more about the wonders of space and also to learn more about the solar energy process since we are using it more and more every day. Solar Energy from Space has evolved immensely in the past few years and has become one

The cells of the adaptive immune system are special types of leukocytes‚ called lymphocytes. There are two main types of lymphocytes‚ B cells and T cells‚ which are derived from hematopoietic stem cells in the bone marrow. T cells are involved in cell-mediated immune response‚ whereas B cells are involved in the humoral immune response. The surface of each lymphatic cell has receptors that enable them to recognize foreign substances. There are two major subtypes of T cells: the helper T cell and

describe the major levels of structure (such as planet‚ star‚ galaxy) in the universe. Planet: (a) Orbits a star‚ (b) large enough for its own gravity to make it round‚ (c) has cleared most other objects from its orbital path. Sun: The star of our solar system. Star: Large‚ glowing ball of ignited gas that generates heat and light through nuclear fusion in its core. Galaxy: A great island of stars in space‚ containing a few hundred million or trillion stars held together by gravity‚ orbiting a
