Hey guys, it's Markie and welcome back to my channel. If this is the first video you're watching from my channel, I suggest you subscribe so that you'll be updated on the educational videos that I'll upload like this. So welcome to another episode of the Senior High School Subject Series that I do here on my channel where I share with you the topics or lessons that I talk about on specific subjects of Senior High School. Before I continue this video, if you're interested in painting or art, or DIY, you can check out Darling Arts channel and be inspired by her beautiful paintings that she uploaded on her channel. I will also link her channel in the description box below so you can check it out.
So let's start the 10 lessons for Biology 1 and 2. General Biology 1 and 2 are specialized subjects for students who will enroll in the STEM strand of senior high school. So our subject for today is General Biology 1. This subject is designed to enhance the understanding of the principles and concepts in the study of biology, particularly life processes at the cellular and molecular levels. This also covers the transformation of energy in organisms.
So content and competency. Content is the lessons or topics that we will talk about in biology 1 and competency is what you will do or need to achieve. So first topic, cell.
Under that, we have cell theory, cell structure and functions, prokaryotic vs eukaryotic cell types, cell modification. So what you will do is you have to explain the postulates of the cell theory. So as early as now, you research for the different cell theory describe the structure and function of major and subcellular organelles you have to research about that another is distinguish prokaryotic and eukaryotic cells according to their distinguishing features I am not sure if you already took this one in junior high school but I think you did and for biology one you can still talk about prokaryotic and eukaryotic cells if you don't know that yet then you can research about that in advance Another is you have to classify different cell types.
Plant, animal tissues, and specify the functions of each. So we have cell types of plant cells and animal cells. So you have to specify their difference. Another under cell is we have cell cycle, the mitosis, and meiosis. What you're going to do is characterize the phases of the cell cycle and their control points.
So you have to read the phases of the cell cycle what is happening to our cells another is you have to describe the stages of mitosis and meiosis so these are the different cell cycles mitosis and meiosis so all you have to do is research for the stages of this cell cycle and describe each stage of this cell cycle another is you have to explain the significance or application of mitosis and meiosis so You have to connect mitosis and meiosis to real-life situations. So, what are the significance or applications of these cell cycles? Another is you have to identify disorders and diseases that result from the malfunction of the cell during the cell cycle. So, you have to read about that. Under cell, we still have the transport mechanisms.
Letter A, simple deflation. Letter B, facilitated transport. Letters.
Letter C, active transport. And letter D, bulk, secular transport. So ano ba yung mga yan?
So ano ba yung kailangan yung gawin? As a STEM student that is who is going to take the subject, you have to describe the structural components of the cell membrane. Ano ba yung mga structural components na makikita mo sa inyong cell membrane?
So you have described that. You also have to relate the structure and composition of the cell membrane to... its function.
Another is you have to explain transport mechanisms in cells. You have to talk about diffusion, osmosis, facilitated transport, and active transport. So as early as now, you read about these transport mechanisms that is going on inside the cell.
Another is you have to differentiate exocytosis and endocytosis. Ano ba yan? So you have to read about that.
Another topic in biology 1 is what we call biological molecules under that we have structures and functions of biological molecules we have carbohydrates lipids proteins enzymes and nucleic acids so what we have to do is we have to categorize the biological molecules you have to categorize categorize that one according to their structure and function or yung mga ginagawa nila sa ating katawan. Explain the role of each biological molecule in specific metabolic processes. So ano ba yung function?
of lipids, of carbohydrates in our metabolic processes. So describe the components of an enzyme. So you read what is an enzyme and describe its component.
Another is you have to determine how factors such as pH, temperature and substrate effect enzyme activity. Another is we have energy transformation we have ATP-ADP cycle photosynthesis and respiration so all you have to do is explain coupled reaction processes and the squadron of ATP in energy coupling and transfer. Another is you have to describe the major features and chemical events in photosynthesis and respiration so you have to research or read about them. You also have to explain the importance of chlorophyll and other pigments.
So for sure, you already talked about this in elementary. So for biology 1, you still have to talk about this one. Describe the significant events of the Calvin Cycle. If you're not familiar with the Calvin Cycle, you can google that right now. And research about that so that you'll have an advantage when you enroll in STEM and take biology 1. Still under energy transformation, you have to distinguish major features of glycogen.
glycolysis, Krebs cycle, electron transport system, and chemosmosis. Describe reactions that produce and consume ATP and explain the advantages and disadvantages of fermentation and aerobic respiration. So basically, that's what you talked about in biology 1. Now let's proceed with general biology 2. So general biology 2 we have, this subject is designed to enhance the understanding of the principles and concepts in the study of biology. particularly hereditary and variation, and the diversity of living organisms, their structure, functions, and evolution.
So remember that you can only take General Biology 2 if you pass or you're done with General Biology 1. So that's still the case, content and competency content, the discussion or lessons, and competency is what you need to do or need to achieve. So for General Biology 2, the first topic is organization. Organismal biology we have plant and animal organ systems and their functions and feedback mechanisms So all you have to do is compare and contrast the following processes in plants and animals So you have to talk about reproduction development nutrition gas exchange transport circulation regulation of body fluids chemical and nervous control immune systems and sensory and motor mechanics Another is you have to explain as a STEM student. You have to explain how some organisms maintain steady and conditions that possess various structures and processes. Describe examples of homeostasis.
Another topic in general biology 2 is genetics. You have to talk about Mendel's law of inheritance, sex linkage, central dogma of molecular biology, and recombinant DNA. What is that?
So all you have to do is predict genotypes and phenotypes of parents and offspring using the laws of inheritance. So if you're not familiar with laws of inheritance, there are a lot of them on Google. you can search for that and study that in advance.
You have to explain sex linkage and recombination. You also have to describe modification to Mendel's classic ratios of gene interaction. Illustrate the molecular structure of DNA, RNA, and protein. So when you talk about illustration, of course, you have to draw that one.
Diagram, another drawing. Diagram the steps in DNA replication and protein. So you research about that in advance.
Another topic for General Biology 2 is the evolution and origin of biodiversity. We have relevance, mechanism, evidence basis, and theories of evolution. All you have to do is describe the general features of the history of life on Earth. So ano ba yan? Another is you have to explain the mechanisms that produce change in population from generation to generation.
And here we are talking about biodiversity. biodiversity and evolution and origin. Another is show patterns of descent with modification from common ancestors to produce the organismal diversity observed today.
And of course, you have to explain evidences of evolution. There are a lot of people. Fourth topic when it comes to general biology tool is the systematics based on evolutionary relationships. So what are you going to do?
Then you have to explain how the structural and developmental characteristics. Relatedness of DNA sequences are used in classifying things. What are those DNA sequences?
That are used in classifying living things. You have to read about that. Identify the unique distinctive characteristics of a specific taxon relative to other taxa.
Another issue to describe species diversity and cladistics including the types of evidence and procedures that can be used to establish evolutionary relationships. So basically, that's what you need to talk about in General Biology 1 and 2 if you're planning to enroll in STEM strand in senior high school. So I suggest you study in advance, especially if you're planning to enroll in STEM because it's not easy or simple to discuss in STEM strand. So that's it guys, I hope you learned something today. If you learned something, don't forget to give this video a like or a thumbs up, share it to your friends, and comment below if you have any questions about system stride or general biology one and two so that pop up a supplement you can also check the description box below for the other videos about the difference in your high school subjects so don't forget to subscribe to my channel for more educational tips and advice this has been your friend sir Markie thank you for watching love alone
