A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.
I would say protein as I believe that carbohydrates are digested faster whereas protein takes longer to break down. It can take up to 3 hours to digest proteins as they are long well soldered molecules which constitute them and as well as being well chewed, the food must be attacked by gastric, pancreatic and billiary juices to render them down.
This would be known as anaphylaxis. I know this very well as I am allergic to so many things. This can result into being life threatning as well. Depending on what the reaction is to, there is things to control the systems til you get help ie., epipens for like bee stings.
Because if you think about it the kingdoms are the houses to these organisims the reason phylum does not belong in fungi because they are two different things Protista is a kingdom only for protist
solution:
The relative constancy of the body or the ability to maintain an iptimim internal environment is called homeostasis.
Homeostasis, refers to stability, balance, or equilibrium. Physiologically, it is the body’s attempt to maintain a constant and balanced internal environment, which requires persistent monitoring and adjustments as conditions change. Adjustment of physiological systems within the body is called homeostatic regulation, which involves three parts or mechanisms:
1. the receptor
2. the control center
3. the effector
The receptor receives information that something in the environment is changing. The control center or integration center receives and processes information from the receptor. The effector responds to the commands of the control center by either opposing or enhancing the stimulus. This ongoing process continually works to restore and maintain homeostasis. For example, during body temperature regulation, temperature receptors in the skin communicate information to the brain (the control center) which signals the effectors: blood vessels and sweat glands in the skin. As the internal and external environment of the body are constantly changing, adjustments must be made continuously to stay at or near a specific value
.
Thus this is the required answer.
