Absorbing prokaryotic cells. This theory is called the endosymbiotic theory.
The early prokaryotic cells that were absorbed likely evolved into mitochondria and chloroplasts, membrane-bound organelles with their own DNA in single chromosomes and their own ribosomes.
Answer:
Explanation:
1. Visual design
Users can be distracted by the lack of visual design on a prototype because wireframes and other low-fidelity prototypes are very basic. This can cause users to comment on the lack of design and colour and distract both themselves and the researcher from the true goals of the project. The extent of this challenge depends on the level of detail within the prototype.
How to get around this: Ensure the user is aware at the start of a session that the website they are about to view is at an early stage of development and so does not look and feel like they may expect. The research may need to be explicit with some users and point out it is not the visual design that we are interested in for today.
2. Partial journeys
Prototypes often cover only partial user journeys, meaning that users may have to be dropped into a journey at a specific point and may lose the context of the overall task or what they would be coming on the site to do.
How to get around this: As well as creating tasks which set the context, consider including some time at the beginning of the session for users to explore the prototype as they would normally do on that website/app, without giving them long enough to discover the prototype journeys. Introductory questions can also be asked at the start of the session to position the user in the right frame of mind for what the prototype will allow them to do, therefore helping to provide some context alongside the task wording.
Answer:
c. our inhibitions and insecurities
Explanation:
The factors that influence what stimuli we notice and try to make sense of are
1. When some certain characteristics of external phenomena attracts our attention. There is an higher chance of noticing it --- things that STAND OUT.✔
2. An individual perception is controlled and regulated by the acuity of his/her senses.
Take for example, a person with a better sense of smell, its more attracted to the aroma of a freshly baked chocolate cake than others -----acuity of our senses.✔
3. Change or variation attracts attention, as this explains why one might ignore a friend's chat but will swiftly notice when his/her friend is tensed. --- Change or variation✔
4. What an individual choose to notice is also regulated by their personality and inner thoughts as morives play a important role in what we see and miss out on.
5. An individual perceive what he wants to perceive ----- the self-fulfilling prophecy (deals with individuality and perception of one's self)
Kindly note that the option c -our inhibitions and insecurities- does not influence what stimuli we notice and try to make sense of.
Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.
Olds and Milner showed that electrical stimulation of particular brain regions could have a reinforcing effect.
<h3>Electrical brain stimulation</h3>
it is commonly known as focal brain stimulation (FBS), is a type of electrotherapy used in clinical neurobiology and research to activate a neuron or neural network in the brain by either directly or indirectly stimulating its cell membrane with an electric current.
<h3>What is the purpose of brain electrical stimulation?</h3>
- Electrical stimulation can be used to alter how the brain functions because electrical charges are what cause brain activity.
- Brain stimulation has been used to treat stress and mood disorders, and it can even make it easier for people to remember things, solve puzzles, and pay attention.
