One way in which organisms maintain homeostasis is by detecting foreign cells and particles like pathogens and cancer cells. once the pathogen is detected and identified, other systems in the organism's body can attack the invader, thus keeping the organism healthier. cells of the human immune system are finely tuned to recognize and respond quickly to disease-causing organisms. (Note: you will find model 1 in the attached files)
A pathogen has entered the bloodstream of an individual. Draw the symbol that represents the pathogen.One response of human immune system is endocytosys of the pathogen by a phagocyte (a type of white blood cell). Refer to model 1. Which diagram in the cell mediated response illustration shows this porcess?Draw the symbol that represents phagocytesAnother type of white cell that is involved in the cell mediated response is a helper T-cellDraw the symbol that represents the helper T-cell in model 1Circle the speciealized surface proteins on a helper T-cellAccordign to model 1, are all the helper T-cell the same? Justify your answer with specific evidence from model 1The following statement are labeled for the cell mediated process in model 1--- a piece of pahtogen is presented on the surface of the phagocyte
--- the helper T-cell disperses a chemical signal to activate other immune response systems
--- the helper T-cell binds to the piece of pathogen presented on the phagocyte
--- Pathogen is broken appart by chemicals in the phagocyte
Determine the order of statements by referring to model 1Decide where each statement belongs in the diagram and label model 1 appropriately. More than one statement might match a diagram, and some diagrams may not match any statement.According to model 1, do helper T-cell interact with a free pathogen in the blood?Answer
The pathogen in the model is represented with a star.The first diagram in the model represents the phagocytosis process. And the phagocyte cell is represented by the bigger irregular cell. In model 1, T cells are the perfectly circular-shaped cells with the Th inside. And the surface proteins in the T-cell are those sticks attached to their membranes. If you look at the model carefully, you will see that these proteins are different in each T-cell. The union site with the antigen changes from cell to cell, making each T-cell specific. One cell has squared binding sites, the other one has semicircular binding sites, while the last one has triangular binding sites. Order of statements: Pathogen is broken appart by chemicals in the phagocyte (Diagram 1 - 3th cell) A piece of pahtogen is presented on the surface of the phagocyte (Diagram 1 - 4th cell) The helper T-cell binds to the piece of pathogen presented on the phagocyte (Diagram 3)The helper T-cell disperses a chemical signal to activate other immune response systems (Diagram 4)T-Cells do NOT interact with free pathogens. They interact with the antigens on the phagocyte cells.Explanation:

Trisha measured the
volume of a cube using a
ruler. The length, width and
height all measured 8 cm.
The mass of the cube was
128 9. what is the density of
the cube? help
Answer:
0.25
Explanation:
density = mass / volume
data given :
mass=128 g
volume of a cube = L *L *L (L is length)
=8*8*8
=512 cm³
density = 128/512
=0.25 g/cm³
Trisha measured the volume of a cube using a ruler. The density of the cube is 0.25 g/cm³.
What is density?
The mass per unit volume is known as density. A scalar quantity, density. It is represented by the letter D, and the Greek letter rho is used as the sign for density. Mass divided by volume is how density is computed.
Mass is a physical body's total amount of matter. Mass is defined as the sum of the moles of the material and the compound's molar mass. Volume is the space taken by an object
Given the mass = 128 g
The volume of a cube = L x L x L (L is length)
Putting the value in the formula
8 x 8 x 8 =512 cm³
Density is mass/volume
Putting the value in the formula
density = 128 / 512 = 0.25 g/cm³
Thus, the density of the cube is 0.25 g/cm³.

What ratio of guinea pigs in the offspring would you predict from a Ss x ss cross?
Answer:
75:25
75% S
25% s
Explanation:
The ratio of guinea pigs in the offspring that we would predict from a Ss x ss cross is 1:1.
What is a genetic cross?
The deliberate breeding of two different individuals that results in offspring that carry part of the genetic material of each parent.
In a cross between a heterozygous dominant (Ss) guinea pig and a homozygous recessive (ss) guinea pig, the expected genotypes would be :
Ss (heterozygous dominant) :1ss (homozygous recessive) : 1S, for every guinea pig that is homozygous dominant (Ss) there will be 2 guinea pigs that are homozygous recessive (ss), resulting in the ratio of 1:1. Therefore, both the ratios will be equal. Therefore, the resulting progeny will have both the genotypic and the phenotypic ratios sames.

Answer:
A
Explanation:
It is the cell membrane
The plasma membrane is a boundary of cell responsible for the movement of any substance in and out of the cell, hence a is the correct option.
What is a cell membrane?All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. The cell membrane controls the flow of substances into and out of the cell.
Watery fluid surrounds and fills cells, this liquid facilitates the movement of substances across the cell membrane as well as within and outside the cell.
Some solutes (solids) can pass through cell membranes depending on their nature.
Therefore cell membrane allows the substance to pass into cell and out of the cell, hence option a is correct.

According to the CDC, is the flu vaccine safe and effective?
Need answer ASAP pls I’ll give brainiest
Answer:
any vaccine effectiveness can vary, recent studies show that flu vaccination reduces the risk of flu illness by between 40% and 60% among the overall population during seasons when most circulating flu viruses are well matched to the flu vaccine.
Explanation:
this is right i had to to a test and a whole lesson over this. ^^^^ that all is from my notes!
Yes, the flu vaccine is safe and effective according to the CDC.
The Centers for Disease Control and Prevention (CDC) recommends annual flu vaccination for everyone aged six months and older, with very few exceptions. The flu vaccine has been extensively studied, and the CDC and other health organizations have found it to be safe and effective in preventing flu infections and reducing the severity of illness for those who do get infected.
The flu vaccine is developed each year to protect against the most prevalent strains of the influenza virus that are expected to circulate during the upcoming flu season. It stimulates the body's immune system to produce antibodies against the virus without causing the flu itself. While the vaccine's effectiveness can vary from season to season due to changes in the circulating flu strains, it still provides significant protection and lowers the risk of severe complications and hospitalization.
As with any medical intervention, there can be some side effects, but they are usually mild and short-lived, such as soreness at the injection site or mild fever. Serious reactions to the flu vaccine are rare. The benefits of getting vaccinated far outweigh the risks, especially for high-risk groups, such as young children, older adults, pregnant women, and individuals with certain medical conditions.
Overall, the CDC and other health authorities strongly recommend flu vaccination as a safe and effective public health measure to protect individuals and communities from the flu and its potential complications. It is an essential part of flu prevention strategies and is encouraged for everyone to help reduce the spread of the virus and its impact on public health.
