Lysogenic means that the virus is able to live and replicate inside the cells of the host …without causing disease. Lysogenic viruses are different from lytic viruses in that they are not able to immediately kill the cells they infect. Lysogenic viruses are able to enter the cells and integrate their DNA into the cells’ chromosomes. This can happen in two ways: (1) the virus can insert its DNA into the host’s chromosome while it…
Unicellular organisms are only made up of one cell. This one cell is responsible for all the functions of the organism. Unicellular organisms can be found in both plants and animals and include things like bacteria and amoebas. One of the key differences between multicellular and unicellular organisms is that multicellular organisms are able to carry out more complex functions than unicellular organisms. This is because multicellular organisms have many cells that can work together…
The blood’s journey starts in the heart, and from there the blood travels to the left ventricle of the heart. Finally, the blood is pumped out into the pulmonary artery and the rest of the body. The inferior vena cava carries blood away from the body. It begins near the heart, and empties into the left atrium. From there, the blood travels to the left ventricle of the heart, and finally out into the pulmonary…
There are plenty of possible triggers why a volcano erupts. Some of these factors include changes in the atmosphere, changes in the Earth’s gravity, and the presence of groundwater. Lava flows are the result of a volcano’s molten rock being expelled. molten rock is expelled from a volcano’s lava chamber when the pressure of the molten rock forces its way out. They are shaped like rivers and can be up to a few kilometers wide.…
Nitrogen is an important nutrient for human health. It is essential for the growth and development of plants and other organisms, and it is also important for the production of DNA, proteins, and other vital molecules. In addition, nitrogen is essential for the production of energy in the body. Nitrogen is found in many different foods and beverages, and it is also found in many fertilizers and other agricultural products. Nitrogen is also a by-product…
The study of ecology is an important part of our understanding the world around us. It helps us to better understand how living things interact with other living things and their environment, as well as how human activities impact ecosystems. Ecology plays a vital role in maintaining the balance of nature. In this article, we’ll look at why ecology is so important, what it does and how it can be used to help improve our…
You may have heard people use the term “state” and wondered if they were talking about a state of matter, or an object’s condition. So what does the word state mean in chemistry? Is it a type of matter, something that changes, or both? A state is defined as “a particular condition at a given time.” The word has many other meanings too! For example: To describe one of the 50 states in America; Or…
Sandstone has a wide variety of uses. It is often mined for use in various construction projects, and it is also used to make glass. Sandstone is formed by the quartz grains in sand deposits becoming cemented together over time. This process usually occurs underground, and huge quarries are dug out of the earth to reach this natural resource. Sandstone usually forms in layers, or strata, making it easier to mine. The most common type…
Meiosis is the process of cell division that creates gametes (sex cells) that are required for sexual reproduction. In meiosis, a cell divides twice to produce four new cells. Each new cell has half the number of chromosomes as the original cell. It is necessary because it helps all sexually reproducing organisms pass down half their genes to their offspring. Sexual reproduction also contributes to genetic diversity, which helps species evolve and adapt over time.…
Esterification is an organic reaction in which two molecules covalently bond to each other with the loss of a small molecule. In a nutshell, esterification is the reaction of an alcohol with either an acid or another alcohol. Commonly, you’ll see this reaction described as: A compound that contains a hydroxyl group (-OH) and is bonded to an alkane chain (CH3CH2) or alkyl group (C6H14) forms esters when it reacts with a carboxylic acid or…
