Page 2 Summary: Detailed Examples and Learning Objectives

This page continues the discussion on kineses, providing a detailed example of woodlice behavior in response to moisture levels. It then outlines learning objectives for the lesson.

The woodlice example illustrates how kinesis works in practice:

  1. In dry conditions, woodlice move more rapidly and change direction more often, increasing their chance of returning to a damp area.
  2. In damp areas, they slow down and change direction less frequently, helping them stay in favorable conditions.
  3. If they remain in dry areas for too long, they switch to moving rapidly in straight lines, increasing their chances of finding a new damp area.

Example: Woodlice exhibit kinesis by changing their movement patterns in response to moisture levels, which helps prevent desiccation and increases survival chances.

The page concludes with three key learning objectives or questions:

  1. What is a stimulus and response?
  2. Describe taxes and kineses.
  3. What is positive and negative taxis?

These objectives summarize the main points of the lesson, focusing on the fundamental concepts of stimuli and responses, the differences between taxes and kineses, and the distinction between positive and negative taxis.

Highlight: Understanding the concepts of stimuli, responses, taxes, and kineses is crucial for A level biology chapter 14 response to stimuli and forms a key part of the AQA A Level Biology topic 6 specification.

Page 1 Summary: Introduction to Survival and Response

This page introduces the fundamental concepts of survival and response in organisms, focusing on taxes and kineses. It begins by defining key terms essential for understanding the topic.

Vocabulary:

  • Stimulus: A detectable change in the internal or external environment of an organism.
  • Response: The result of a stimulus detected by a receptor, which may involve movement or behavioral change.
  • Receptor: An organ or specialized cell that can detect the change causing the stimulus.
  • Taxis: A simple response whose direction is determined by the direction of the stimulus.
  • Kinesis: A response where the organism doesn't move directly towards or away from a stimulus but changes its speed and rate of direction change.

The page explains that the ability to respond to stimuli is a characteristic of life that enhances survival chances. It outlines the basic process of stimulus and response:

stimulus → receptor → coordinator → effector → response

This process can involve either chemical control or nerve cells. The text emphasizes that organisms with more appropriate responses have a greater chance of survival and passing on their genes.

Highlight: The ability to respond to stimuli is crucial for survival, allowing organisms to avoid dangers and find resources.

The page then delves into more detailed explanations of taxes and kineses:

Taxes are classified as positive towardsthestimulustowards the stimulus or negative awayfromthestimulusaway from the stimulus and are named based on the nature of the stimulus.

Example: Single-celled algae exhibit positive phototaxis by moving towards light, which is essential for their photosynthesis and survival.

Kineses are described as responses where the organism's movement is not directly towards or away from the stimulus. Instead, the organism changes its speed and rate of direction change.

Highlight: Kineses are particularly important when a stimulus is less directional, such as with humidity or temperature gradients.

The page concludes with an example of kinesis in woodlice, illustrating how this behavior helps them maintain optimal moisture conditions and increases their chances of survival.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Stefan S

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Android user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Anna

Best app on earth! no words because it’s too good

Thomas R

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

Basil

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

David K

iOS user

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
