How do helper T cells activate?
Answers
Helper T cells are activated by a process called antigen presentation, in which APCs (antigen presenting cells) present a foreign invader's peptides on their surface in the context of MHC molecules. Once the helper T cells bind to the complex, they become activated, multiply, and release signaling molecules that coordinate the immune response.
Helper T cells, also known as CD4+ T cells, are a type of white blood cell that play a critical role in the immune system. They help to coordinate and regulate the immune response to invaders such as viruses and bacteria.
Helper T cells are activated by a process called antigen presentation. This process begins when a foreign invader, such as a virus, enters the body. The invader is then recognized by specialized cells called antigen-presenting cells (APCs). These APCs, such as dendritic cells, macrophages, and B cells, engulf the invader and break it down into small peptides.
These peptides are then displayed on the surface of the APC, along with a special protein called a major histocompatibility complex (MHC) molecule. This complex is what the helper T cells recognize. Helper T cells have special receptors called T cell receptors (TCRs) on their surface that can bind to the MHC-peptide complex.
Once the helper T cells bind to the complex, they become activated and start to multiply. They release a variety of signaling molecules, such as cytokines, that attract other immune cells to the site of infection and help to coordinate the immune response. Activated helper T cells also differentiate into different subsets such as TH1, TH2, TH17, Tregs etc each with different functions.
It's important to note that helper T cells can only be activated by foreign invaders that are recognized by the MHC complex. This is why self cells and molecules are not attacked by the immune system.

Reasoning
Explain why your evidence (what you wrote in Box 2) supports your claim (what you wrote in Box 1). Also, explain the scientific principles behind your reasoning. Remember to provide enough detail so that a friend who did not do the experiment could learn from your description
Answers
Answer:
Claim: Increasing the amount of foliage does not lead to an increase in the final number of slinquettes with red, short fur.
Evidence: The data table shows the results of eight trials where the amount of foliage was manipulated. In all trials, regardless of the amount of foliage (whether "lots" or "some"), the final number of slinquettes with red, short fur remained at 0. There were no instances where increasing the foliage resulted in an increase in the population of slinquettes with red, short fur.
Reasoning: The evidence from the data table supports the claim that increasing the amount of foliage does not lead to an increase in the final number of slinquettes with red, short fur. This suggests that the presence or absence of foliage does not have a significant impact on the population of slinquettes with red, short fur.
Based on the provided data, it is reasonable to infer that factors other than foliage, such as temperature, fur color mutation, and fur length mutation, may have a stronger influence on the population dynamics of slinquettes. These factors could be responsible for the observed patterns in the data.
It's important to note that the reasoning provided here is based solely on the given data and analysis. In a real scientific investigation, additional factors, experimental controls, and statistical analysis would be required to draw definitive conclusions.
which statement describes the way in which phosphorylation directly contributes to signal transduction?
Answers
Proteins can connect with new binding partners thanks to phosphorylation, which modifies the structure of the protein.
Phosphorylation sites are created by protein kinases (also known as "writers"), frequently have an impact after being recognized by phospho-binding proteins (also known as "readers"), and are afterwards eliminated by protein phosphatases (also known as "erasers").
This writer-reader-eraser toolbox has been crucial in the evolution of new functionalities necessary for the development of multicellular organisms and enables phosphorylation events to control a wide range of regulatory activities. Typically modular in organization, the proteins that make up this system of protein kinases, phospho-binding targets, and phosphatases are made up of several globular domains and smaller peptide motifs having binding or catalytic capabilities.
Through genetic recombination, the linking of these binding and catalytic modules in novel ways, as well as the choice of certain domain combinations, have aided in the emergence of new, physiologically advantageous processes. Conversely,

Which body response to an acute inflammation will the nurse assess if the client is experiencing a systemic response?
Answers
The body response to an acute inflammation that the nurse will assess if the client is experiencing a systemic response is Fever and tachycardia.
Acute inflammation occurs when a specific injury occurs in which certain soluble mediators like cytokine, acute phase protein and chemokines are released to the injury site that promotes migration of neutrophils and macrophages.
The signs of inflammation include heat, pain, redness, swelling, pain and loss of function.
When acute inflammation does not settle in a week or so it can lead to chronic inflammation that can last for years also.
Fever and tachycardia are the common responses seen during acute inflammation.

When you get cut, your skin cells release hormones that signal platelets to come and stop the bleeding. Platelets then release more hormones that signal even more platelets to help stop bleeding. The hormone signals continue until the cut is closed. Explain WHY this is a positive feedback loop.
Answers
Answer:
See the answer below
Explanation:
The process of blood clotting is a positive feedback loop because it is a process that needs to go into completion, unlike in negative feedback loops in which the initial status quo (the setpoint) needs to be returned to.
In positive feedback loops, when the system senses a change from normal, the control center increases this change until the initial process that triggered the change goes to completion.
The bleeding in a cut skin needs to be stopped, hence, the control center will signal the effector to keep releasing hormones for more platelets to be formed until the bleeding subsides. Hence, the process is a positive feedback loop.

In the somatic cell of a mammalian female, one of the two x chromosomes is randomly inactivated and condensed, resulting in the formation of a ________.
Answers
In the somatic cell of a mammalian female, one of the two x chromosomes is randomly inactivated and condensed, resulting in the formation of a Barr Body.
One of the two X chromosomes is randomly and irreversibly inactivated in cells other than egg cells very early in female embryonic development. The term "X-inactivation" or "lyonization" refers to this process. Females, like males, have one functioning copy of the X chromosome in each body cell thanks to X-inactivation. In placental mammals like humans, the choice of which X chromosome will be inactivated in a certain embryonic cell is random, but if an X chromosome is inactivated, it will be inactive for the lifetime of the cell and its offspring in the organism (its cell line). The outcome is that all of the organism's cells have an equally distributed distribution of inactivated X chromosomes, with roughly half of the cells having an inactivated paternal X chromosome and the other half having an inactivated maternal X chromosome (X-inactivation).
