Answer: 1: allergic disorders
2. Immunodeficiency disorders
3. Autoimmune disorders
4. Cancers
Immune system overreacts to an antigen part of the immune system does not function properly the body's immune system attacks its healthy cells, mistaking them for pathogens masses of cells form and steal nutrients from healthy.
What do you mean by Allergy?Allergy may be defined as a reaction by our immune system to something that does not trouble most other people. It affects a person more specifically.
When a person gets affected by any allergy, the immune system of that person may overreact by producing more antibodies. These antibodies attack the allergen particles and cause adverse symptoms.
A person who has allergies has them because his or her body over reacts to a material that would otherwise be ignored. It is an overreaction of the immune system triggering a immune attack response that is unneeded.
Therefore, a person who has allergies has a compromised immune system because the body's immune system overreacts to an antigen.

A cell has a 1% salt concentration. It is placed into a solution containing a 10% salt concentration.
What will happen to the cell?
Choose 1 answer:
Water will move out of the cell, causing it to swell.
Water will move into the cell, causing it to shrink.
Water will move into the cell, causing it to swell.
Water will move out of the cell, causing it to shrink.
Answer:
Water will move out of the cell, causing it to shrink.
Explanation:
When something with a low salt concentration is placed in a higher concentration of salt, the salt in the solution will try to suck out the water in the cell. Just remember why we hate salt, because it sucks! There's a little joke to help u remember. Thanks, Ms. Hoj :)
Answer:
CORRECT (SELECTED)
Water will move out of the cell, causing it to shrink.
Explanation:
The cell has lower concentration of solute and a higher concentration of water than the solution it is placed in. This means that water will move out of the cell, causing it to shrink.
Which of the following is always true of two organisms in
the same taxonomic class?
A.They can breed with one another
B.They have certain physical features in common
C.they evolved at the same time
D.they live in the same ecosystem
Answer:
they can breed with one another, they have certain physical features in common, they evolved at the same rate, they live in the same ecosystem. Lions and house cats share common features, but cannot breed with one another.
Explanation:
They share a common ecology, they may breed with one another, share some physical characteristics, evolve at the same rate, and inhabit the same ecosystem, hence option D is correct.
What are the taxonomic classes?If two species are members of the same class, they are also members of the same higher-level taxon. They share the same phylum and kingdom in this instance.
Kingdom, phylum or division, class, order, family, genus, and species are the seven main taxonomic ranks.
The taxon with the greatest number of species is the kingdom. In taxonomy, it is the broadest category into which the creatures can be divided.
The classification of five kingdoms was made by R.H. Whittaker. The kingdoms of Monera, Protista, Fungi, Plantae, and Animalia are included in this classification.
Therefore, option D is correct.

Seth will attend college in the fall and live in the dormitory, so he is required to obtain a blank against bacterial meningitis, which will stimulate his body to produce immunity to the disease. He reads that meningitis is a fast-acting and potentially fatal disease, transmitted by blank in the respiratory droplets of infected individuals. The bacteria are blank that cause disease by destroying blank and releasing blank that disrupt the body’s normal homeostasis. Bacterial infections are treated with blank , which block the growth and reproduction of bacteria.
Key answer: bacteria, vaccine, cells, pathogens, toxins, antibiotics
Answer:
vaccine
bacteria
pathogens
cells
toxins
antibiotics
Explanation:
Bacterial meningitis is a serious disease that is caused by an infection which results into Inflammation of brain and spinal cord membranes.
It is generally caused by virus but also caused by fungus and bacteria. A vaccine is required to fight against the bacterial meningitis. Symptoms include fever, stiff neck and headache. This disease is carried by the bacteria present in the throat of infectious person and can transmit through coughing, sneezing and kissing. The bacteria are the pathogens, releases a toxin which destroy cells and surface components of nervous system.
This disease is treated with intravenous antibiotics and corticosteroids (sometimes).
Hence, the correct answers for blanks are vaccine, bacteria, pathogens, cells, toxins, and antibiotics in sequential order.

What part of the respiratory tract is considered the respiratory zone?
A. Bronchioles
B. Larynx
C. Trachea
D. Alveoli
Answer:
D. Alveoli
Explanation:
Functionally, the respiratory system is separated into a conducting zone and respiratory zone:
Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.
Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.
Answer:
Yep, the correct answer is D.) Alveoli

What is currently happening with Mount Etna?
Answer:
As Italy’s National Institute of Geophysics and Volcanology (INGV) explains on a recent blog post, the nascent eruption began on the night of May 29. Starting off by producing a thick column of ash rising from the New Southeast Crater, it gave way on May 30 to a far more lava-heavy display in the area, featuring two fissures blenching out lava.
Answer:
There is currently no eruptive activity at the volcano involving fresh lava and monitoring signals do not suggest an immediate change likely; only a weak thermal anomaly continues to be present from the southeast crater complex.

write a paragraph to show your knowledge about diabetes that include the following terms:
Glucose, Glucagon, Pancreas, Negative Feedback, Homeostasis, and Liver
Answer:
Glucose is a simple sugar molecule that helps play a role in high/low blood sugar levels. If your blood level is too low Glucagon is released to increase your blood sugar and if it’s too high Insulin is secreted to lower blood sugar; both Insulin and Glucagon are hormones.This being said these two hormones are secreted by the pancreas. Both of these two hormones are examples of negative feedback leading to a stability In homeostasis. It is regulated by the liver, however if homeostasis is disrupted the body will stop functioning properly leaving no insulin to be produced. Therefore the end result is Diabetes

1. A. What is diffusion?
1. B. Use diffusion to
explain what happens when you drop a
sugar cube into a mug of hot tea.
2. A. What is osmosis?
2. B. Describe how water molecules
move through the cell membrane during
osmosis.
Answer:
Diffusion is the spreading of something more widely. When you drop a sugar cube in hot tea the sugar cube spreads out and the sugar starts to dissolve in the tea. Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. If the concentration of water molecules ouside the cell is lower than the concentration of water molecules outside the cell then the water moves out through osmosis. Water travels through the cell membrane.
