41.Which statement best describes the relationship that exist among proteins, DNA, and cells
Romashka-Z-Leto [24]
41. C.DNA is made up of proteins, which tells a cell how to function
42.
<span>C. So they can move materials from one area of the cell to another quickly

A DNA is made of proteins which was synthesized by ribosomes of the cell to produce protein and these proteins are churned into mRNA and then these mRNA and used to catalyse the DNA production. DNA of a cell in the nucleus is the programmed individuality that controls, manages and organises the entire cell to function and initiate cellular activities.

It is more efficient, thus, to move materials quickly.

What occurs if a t cell binds to an antigen and the t cell does not receive a co-stimulatory signal?
tresset_1 [31]
The correct answer is that "the T cell enters a state of anergy".

The activation of T cells requires two signals: (1) antigen specific signal presented by an antigen presenting cell (either a macrophage or a dendritic cell) that activates t cell receptors and (2) co-stimulatory signals that is not antigen specific but rather found in the plasma membrane of the antigen presenting cell (i.e. CD28). In the absence of a co-stimulatory signal, the t cell will enter a state of anergy or the inability to produce an immune response toward an offending antigen.

I Will DEEM BRAINLIEST!!!!! What problem did run into the most when you tested your prototypes? What did you do to fix this prob
mixas84 [53]

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.
