When a honey bee stings or a pathogen attacks, the body elicits an inflammatory response. Label the processes that happen during an
inflammatory response.
The inflammatory response is a type of body response produced in response to damaged tissue, attack of pathogen and or any other cause.
The body shows an inflammatory response in the following manner:
1. Recognition of stimulus- receptors recognize the antigens.
2. Release of inflammatory markers: affected cells produce chemicals like histamine, bradykinin, and prostaglandins.
3. Vascular permeability changes and leukocyte (WBC) recruitment- released chemicals causes the blood vessels to leak fluid causing swelling and attract WBC.
4. Accumulation of leukocytes- WBC performs the process of phagocytosis which eats dead or damaged cells and germs.

Explain the importance of gene regulation in prokaryotic cells.
-Explain the importance of gene regulation in eukaryotic cells.
Answer:
Prokaryotic cells can only regulate gene expression by controlling the amount of transcription. As eukaryotic cells evolved, the complexity of the control of gene expression increased. For example, with the evolution of eukaryotic cells came compartmentalization of important cellular components and cellular processes.

Explanation:
AMP-PNP is a non-hydrolyzable ATP analog that cannot be metabolized by cells. Taurocholate is a bile acid that helps emulsify fats. When taurocholate is added to hepatocyte cell culture, it accumulates in those cells. The graph below shows the rate of cellular accumulation of the drug taurocholate in the presence of either no ATP, ATP, or AMP-PNP. Based on this data, describe the mechanism by which taurocholate enters the cell. Justify your answer.
Answer:
ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient.
Explanation:
ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell.
What is ATP?
A vital "energy molecule" present in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers energy to cells by releasing its phosphate groups when it interacts with enzymes like ATP triphosphatase.
Particular to plants and cyanobacteria is the process of photophosphorylation. During photosynthesis, it is the conversion of ADP to ATP utilizing solar energy. In the mitochondria of a cell, the process of cellular respiration also results in the formation of ATP.
This can be done through either anaerobic or aerobic respiration, depending on whether oxygen is present.
Therefore, ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell.

If human red blood cells are placed in a 0 osmoles/L solution, a 100 osmoles/L solution, a 300 osmoles/L solution, and a 500 osmoles/L solution, then _________________ will be the isotonic solution.
OPTIONS:
0 osmoles/L solution
100 osmole/L solution
300 osmoles/L solution
500 osmoles/L solution
If human red blood cells are placed in solutions of different osmolarity, then the 300 osmoles/L solution will be the isotonic solution.
An isotonic solution to the red blood cell would be a solution that has the same solute concentration as the red blood cell.
Isotonic solutions are different from hypotonic and hypertonic solutions. Hypotonic solutions would have lower solute concentrations than the red blood cell while hypertonic solutions would have higher concentrations than the red blood cells.
The red blood cells of humans have a certain amount of solute in their cell sap which has been approximate to be between 286 and 295 osmoles/L. Thus, the only solution close to being an isotonic solution to these cells would be the 300 osmoles/L solution.
More about osmolarity can be found here: https://brainly.com/question/8144230
Answer: 300 osmoles/ L solution
Explanation:
The 300 osmoles/ L solution is the solution closest to the osmolarity of a normal human red blood cell.
This means that the 300 osmoles/ L solution is the isotonic solution. If added to human red blood cells, the shape and size of the red blood cells with remain as they were, unchanged (unlike if a hypotonic/ hypertonic solution was added.)

Beaker A contains 6 liters of water and 1 osmole of glucose. Beaker B contains 10 liters of water and 2 osmoles of glucose. Which one has the greater osmolarity and by how much?
From the ratio of glucose osmole to the volume of water in the two beakers, beaker B would have the greater osmolarity.
The term osmolarity refers to the number of particles of solutes or osmoles of substances per liter of solution.
In this case, the osmolarity of beaker A can be calculated as;
1 osmole/6 liter
= 0.167 osmolar
The osmolarity of beak B can be calculated as:
2 osmoles/10 liter
= 0.2 osmolar
Thus, beaker B with 0.2 osmolar has the greater osmolarity when compared to beaker A with 0.167 osmolar.
More on calculating concentrations can be found here: rainly.com/question/17329736
Answer: B
beaker A is 0.16 Osm/L and Beaker B is 0.2 Osm/L Beaker B has a greater osmolarity by 0.04 Osm/L

What factors create deep ocean currents
Answer:
Deep currents are driven by temperature and water density/salinity. Of course, deep currents impact surface currents, which carry warm water to the poles. Surface currents are also driven by global wind systems fueled by energy from the sun. Factors like wind direction and the Coriolis effect play a role.
