Cell Division‚ Heredity‚ and Rcolution Practice Questions Cell Division An organism is heterozygous at two gene loci on different chromosomes. Explain how these alleles are transmitted by the process of mitosis to daughter cells. After mitosis the parent cell’s genome is dividedninto two daughter cells. In most eukaryotes‚ the nuclear envelope that separates the DNA from the cytoplasm disassembles. The chromosomes align themselves in a line spanning the cell. As the cell elongates‚ corresponding

or made in the body from other energy sources like carbohydrates. Calories ingested in a meal and not used immediately by tissues are converted to triglycerides and transported to fat cells to be stored. Hormones regulate the release of triglycerides from fat tissue so they meet the body’s needs for energy between meals. Excess triglycerides in plasma is called hypertriglyceridemia causing obesity. It’s linked to the occurrence of coronary artery disease in some people. Elevated triglycerides may

Relationship between Climate Change and Migration There are many ways which people might be displaced or compelled to migrate because of climate change and extreme weather. Rapid – onset events include hurricane and floods which lead to displaced people temporarily. Drought and desertification are called slower – onset events. Despite slower – onset events are a gradual effect of humankind; it can become more dangerous for a long time for environmental and humankind. Droughts have already affected

Cell Structure and FunctionAbstractThis report is about cell structure and function. The cell is the basic unit of life. All living things are madeof cells. By doing this lab‚ I hoped to learn how a cell looked and how it functioned. I also wanted toknow the differences between prokaryotic cells and eukaryotic cells.IntroductionThe concept of this lab is producing a replica of an animal cell‚ and a plant cell. Producing the models of the cells helps to provide a better understanding of each cell

Telomerase is an enzyme that adds the end of telomeres to the DNA in germ cells. A nucleoid is the place in bacterium where DNA is found. Nucleoids are not encompassed by a membrane. Chromatin is located in chromosomes and it contains RNA‚ DNA‚ and different proteins. Heterochromatin is DNA that is in very tightly bound irregular

From time immemorial human race knew that the ultimate source of energy for the earth is from the sun. Modern science has established that this energy is quantifiable‚ for better understanding‚ as electromagnetic radiation‚ EMR. Radiations

Albert C. Perez May 10‚ 2017 The article “The evolutionary psychology of hunger”‚ focuses on the “coordinating mechanisms” of the human body which are set up to deal with the physiological and psychological aspects. The general question of the article is how hunger plays a part in influencing these “coordinating mechanisms” in order to solve an “adaptive problem” and to what degree. These mechanisms according to the article influence things such as our ability to focus on tasks depending on the

In biochemistry we study about the cell it’s parts‚ functions and chemical reactions‚ a medical technologists should understand the cell because it is the cell‚ which is being observed whenever someone is trying to figure out what is wrong with his or her health. There is what we call the “cbc” or complete blood count this is an evaluation of the red blood cells‚ white blood cells and platelets‚ if you know nothing about cells it will be impossible for you to figure out what is doing

Evolutionary Psychology of gender development emphasizes that adaptation during the evolution of human produced psychological differences between males and females. Evolutionary psychologist argue that primarily because of their differing roles in reproduction‚ males and females faced different pressures in primeval environments when the human species was evolving. So according to evolutionary psychologist females contributions to the gene pool were improved by securing resources for their offsprings

Inhalation (Breathing in) As you inhale‚ your diaphragm contracts or tightens and moves downward and this lead to increases the space in your chest cavity which causes your lungs to expand. The intercostal muscles that are found between your ribs helps with enlarge the chest cavity as they contract which pulls your rib cage both upward and outward as you inhale. The expandation of your lungs causes the air to be breathed in through your nose or mouth. The air goes down your windpipe and into lungs
