As we have discovered, Biology is a very broad subject covering a huge number of topics. As such, there is also a vast amount of terminology to get your head around.

But what if you only plan to take Biology at GCSE leveland then want to move onto a whole different area of studies? Do you still need to put in effort learning lots of scientific terminology even though you may never use it again? Also, by grasping the key terminology of GCSE Biologythen you will find it much easier to grasp new biological words and terms should you choose to further your education within the subject area.

However, because we are aware that not everyone aspires to study Biology through to A Level and beyond, we will focus primarily on the bare essentials, starting with the topics that you will study as part of your two-year course.

At this foundation level, though, you will surely come to realise that the language you first thought was a bit baffling actually isn't that difficult at all! Hopefully, by the end of this blog you will be well on your way to loving the interesting subject! AQA officials have worked alongside teachers to create a specification that will stimulate and motivate students. This updated course incorporates a range of practical as well as evaluative topics, designed to answer that big question: How does Science work?

The specification is based on a series of topics related to the living world and relevant to students. It is designed to help them understand how Science can be used to explain the world in which they live and the impact humans have on it.

The topics covered are: Cell Biology, Organisation, Infection and response, Bioenergetics, Homeostasis and response, Inheritance, variation and evolution and Ecology. The assessment offered by AQA is split into two examscovering roughly equal proportions of the topics covered.

Here are the topic terms explained to put you one step ahead when you begin your GCSE Biology course. Cell Biology is the study of the structure and the function of cellsexploring the concept that the cell is the fundamental unit of all living organisms. The term encompasses the characteristics of a cell, meaning the tissues and organisms that each one composes. Since the cell is the smallest unit of a living organism, these building blocks of life must be examined under microscope.

Organisation is a biological term used to describe the hierarchy of biological systems and structures. As a word that is quite familiar to most societies, you may recognise this term as one which describes the process or state wherein an infectious agent invades the tissues of the hosting organism and multipliesforming a disease or illness.

Glossary of Biological Terms

Infectious agents, which are not normally found in the body, can be viruses, bacteria or parasites. Bioenergetics is concerned with both Chemistry and Biology simultaneously, looking at the energy that makes and breaks chemical bonds in molecules found in living organisms.

Homeostasis is a term which refers to the ability of a cell or group of cells to look for and maintain a stable condition when dealing with external changes. This is commonly used to describe the functions of body parts like the kidney, liver and skin, which each strive to maintain a constant internal environment no matter what the body is up against externally.

As a biological term, inheritance means the process of transmitting characteristics genetically from parent to offspring. Variation, in biological terms, refers to any differences between cells, organisms or groups of organisms caused by genotypic variation. This can also indicate any differences caused by environmental factors, specifically called phenotypic variation. Evolution is the natural change in heritable characteristics of living organisms over consecutive generations.

There is usually a change in the genes of a population from one generation to the next, resulting from mutation, genetic drift or natural selection. The reason for such evolution is for the organism to adapt physically or in behaviour. Ecology is a branch of Biology which is concerned with the relationships between organisms and their physical surroundings. The interdisciplinary field includes aspects of Biology and Geography.

As we have explored in some of our other posts re GCSE Biology, contemporary scientists don't feel that educational courses reflect the new advancements in Biology. Advances in technology are forever changing what we are capable of doing and finding outnot just in the world of science, so it is inevitable that this modern technological era has has a huge influence on Biology in recent years, as shown by the outstanding breakthroughs within the field.

In fact, modern molecular Biology relies very heavily on new technologies. However, the technological components of Biology courses at this level have scarcely changed over the last few decades.

The Essential Vocabulary to Help With Biology Lessons

Scientists believe that modern Biology courses, if they want to really encourage young biologists and give them a real insight into the live science as it exists today, should bring courses up to date and make them more relevant to the discipline. These concepts, which are described as bioinformaticsare important to contemporary biologists and therefore so is the vocabulary linked to them too.Attribution CC BY.

This book is the perfect amount of content for an introductory, non-majors biology course, especially those taught in a condensed, single-semester format. All of the major units are covered without excessive detail and organized in a logical Comprehensiveness rating: 4 see less. I did not come across any profoundly inaccurate statements but found many topics are oversimplified.

The text focuses more on fundamental principles but adds new research into just about each section. Usually there is not enough content within the text on these newer topics and gaps would need to be filled in by the instructor. Vocabulary is suitably defined throughout the text and topics are kept well separated by headings to provide natural breakpoints in content.

Each section is relatively the same length and appropriately longer or shorter when necessary. It is easy to select the desired content by chapter and sub-section. I did not run into any broken links.

The search function was easy to use and very reliable. There are not many cultural or historical references. The text fails to provide examples that break the stereotypical pattern of scientists and does not introduce students to scientists from different cultures. There is no reference to even general research ethics or examples of current bioethical concerns.

A good choice for a non-major or survey course in Introductory Biology. I just used it for the first time this past semester and plan to continue using it in future iterations of the course. This textbook covers all of the major areas in basic biology: the chemistry of life, cell respiration, photosynthesis, cell structure, genetics, evolution, cell division, biotechnology, species diversity, body systems, and ecology.

The concepts Comprehensiveness rating: 5 see less. The concepts are described at the appropriate depth for an introductory biology course, such as Human Biology.

Each chapter contains references, appropriately defined key terminology, a chapter summary, and content review questions. Supplementary images and diagrams are comprehensive, as well, and reflect and enhance the textual content. I found the content to be accurate to the degree that we cover materials in a non-majors course.

There are items that are simplified slightly, but this is the case in all introductory texts. I feel comfortable with the accuracy.

Even if this an array BigML. Specifies the type of ordering followed to build the model.

There are three different types that you can specify: 0 Deterministic 1 Linear 2 Random For more information, see the Section on Shuffling your dataset below. To get the final number of candidate fields we round down to the nearest integer, but if the result is 0 we'll use 1 instead.

Sets the number of random fields considered when randomize is true. Example: 10 randomize optional Boolean,default is false Setting this parameter to true will consider only a subset of the possible fields when choosing a split. See the Section on Random Decision Forests below. The range of successive instances to build the model. See the Section on Sampling below.

So, if it is 3, then a both children of a new split must have 3 instances supporting them. Since instances may have non-integer weights, non-integer values are valid.

Example: 16 tags optional Array of Strings A list of strings that help classify and index your model. By default, rows from the input dataset are deterministically shuffled before being processed, to avoid inaccurate models caused by ordered fields in the input rows. Since the shuffling is deterministic, i. However, you can modify this default behaviour by including the ordering argument in the model creation request, where "ordering" here is a shortcut for "ordering for the traversal of input rows".

The row range is specified with the range argument defined in the Section on Arguments above.

To specify a sample, which is taken over the row range or over the whole dataset if a range is not provided, you can add the following arguments to the creation request: Finally, note that the "ordering" of the dataset described in the previous subsection is used on the result of the sampling.

The default is false. When randomized, the model considers only a subset of the possible fields when choosing a split. The size of the subset will be the square root of the total number of input fields. So if there are 100 input fields, each split will only consider 10 fields randomly chosen from the 100.

Every split will choose a new subset of fields. Although randomize could be used for other purposes, it's intended for growing random decision forests. To grow tree models for a random forest, set randomize to true and select a sample from the dataset. Traditionally this is a 1. Once a model has been successfully created it will have the following properties. This will be 201 upon successful creation of the model and 200 afterwards.

Make sure that you check the code that comes with the status attribute to make sure that the model creation has been completed without errors. This is the date and time in which the model was created with microsecond precision. It has an entry per each field type (categorical, datetime, numeric, and text), an entry for preferred fields, and an entry for the total number of fields. It includes a very intuitive description of the tree-like structure that makes the model up and the field's dictionary describing the fields and their summaries.

In a future version, you will be able to share models with other co-workers or, if desired, make them publicly available. This is the date and time in which the model was updated with microsecond precision. A Model Object has the following properties: Creating a model is a process that can take just a few seconds or a few days depending on the size of the dataset used as input and on the workload of BigML's systems.

The model goes through a number of states until its fully completed. Through the status field in the model you can determine when the model has been fully processed and ready to be used to create predictions.

Support is a number from 0 to 1 that specifies the minimum fraction of the total number of instances that a given branch must cover to be retained in the resulting tree.
