Master Segun's Class. In today’s class, we will be talking about the biology of heredity (genetics). Enjoy the class! 𝗕𝗶𝗼𝗹𝗼𝗴𝘆 𝗼𝗳 𝗛𝗲𝗿𝗲𝗱𝗶𝘁𝘆 (𝗚𝗲𝗻𝗲𝘁𝗶𝗰𝘀) CONTENT 1. Definitions of genetic terms 2. Hereditary variation and causes of variation 3. Transmittable/transmissible characters 4. How characters get transmitted 5. Mendel’s work in genetics Definitions of Genetic Terms 1. Genetics is the scientific study of heredity and variation in all living things. The word genetics was coined by Dilliam Bateson (1906). 2. Hereditary/Inheritance is the transmission and expression of characters or traits from parents to offspring. It accounts for the usual resemblance between a parent and its offspring. 3. Variation is the differences which exist between parents and offspring and among the offspring. 4. Genes are hereditary or basic units of inheritance located in chromosomes and responsible for the transmission of characters from parents to offspring. The hereditary units...

 Master Segun's Class Welcome to class! In today’s class, we will be talking about wave motion. Enjoy the class! 𝗪𝗮𝘃𝗲 𝗠𝗼𝘁𝗶𝗼𝗻 Wave motion is the transfer of energy and momentum from one point of the medium to another point of the medium without actual transport of matter between two points.  Wave motion is classified into three different ways they are, 1. The medium of propagation, 2. The dimensions in which a wave propagates energy 3. The energy transfer Classification of Wave Motion: Based on the Medium of Propagation Classification of Wave Motion Based on the Medium of Propagation Number of Dimensions a Wave Propagates Energy BASED ON THE TRANSFER OF ENERGY 1. Standing waves (or stationary waves) 2. Progressive wave Standing waves remain confined to a region without any transfer of energy and momentum whereas the progressive waves transfer energy and momentum between the particles of the medium. MECHANICAL WAVES (ELASTIC WAVES) The waves which require a material me...

 Master Segun's Class. I am eager to have you join us this weekend class!! In today’s Biology class, We will be learning about Balance in Nature. We hope you enjoy the class! CONTENT Dynamic Equilibrium in Nature Factors Affecting Population Abiotic Factors Affecting Population Biotic factors affecting Population Family planning and birth control DYNAMIC EQUILIBRIUM IN NATURE When population-influenced factors (abiotic and biotic) are favourable, growth is promoted but when they are unfavourable growth is retarded. A factor which limits the population growth is called a LIMITING FACTOR. The sum of all the limiting factors is known as ENVIRONMENTAL RESISTANCE The net effect of the abiotic and biotic factors is at a point, the population size of living organisms tends towards a dynamic equilibrium known as BALANCE IN NATURE. When the population increases, the environmental resistance increases too. For instance, food decreases in a population and this results in a competition which l...

Master Segun's class.  Welcome to Class!! e I am eager to have you join me in this weekend class!! In today's Biology class, We will be learning about Overcrowding and Food Shortage. We hope you enjoy the class! CONTENT Overcrowding Factors Causing Overcrowding Effects of Overcrowding Adaptation to Overcrowding Food Shortage 𝗢𝗩𝗘𝗥𝗖𝗥𝗢𝗪𝗗𝗜𝗡𝗚 This is a situation in which a population increases beyond a point called the carrying capacity where the resources (eg food and space) are not enough to support all the individuals in the population. Therefore, overcrowding reduces the food and space available for individual species in the population. FACTORS CAUSING OVERCROWDING 1. Natality: An increase in the rate at which a particular species gives birth in a restricted area result in overcrowding. 2. Increase in the food supply 3. A decrease in mortality: Overcrowding results when the rate of death of organisms in a habitat is lower than the rate of birth. 4. Immigration: Inflo...
