write a paragraph to show your knowledge about diabetes that include the following terms:
Glucose, Glucagon, Pancreas, Negative Feedback, Homeostasis, and Liver

Answers

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

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.

2. A. What is osmosis?

2. B. Describe how water molecules
move through the cell membrane during
osmosis.


Answers

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.

Diffusion is the movement of particles from a higher concentrated area to a lower concentrated area
Omosis is the movement of solvent particles across a sermipermeable membrane from a dilute solution into a concentrated solution

What part of the respiratory tract is considered the respiratory zone?
A. Bronchioles
B. Larynx
C. Trachea
D. Alveoli

Answers

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.

Yep, the correct answer is D.) Alveoli

Explanation:

Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.

What do you mean by traits?

Traits may be defined as the appearance or manifestation of the desired characters. Traits are also known as phenotypes.

Every factor or gene has two alternative copies, one comes from the father and one comes from the mother. These two copies are present in the same location on the homologous chromosome. They are known as alleles of each other.

Therefore, Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.
